The activity type filtering was not stable in relation to addresses
filter which was generating unexpected Send/Receive type in the
corner-case when both sender and receiver was in the address list.
Updates status-desktop #11960
Brings consistency in case when sender and receiver are both in the
filter address list. This fixes the case of sender and receiver in
addresses and filters out duplicate entries.
Also
- refactor tests to provide support for owners
- adapt TestGetActivityEntriesWithSameTransactionForSenderAndReceiverInDB
to the use of owner instead of from
Trigger async fetching of extra information on each activity filtering
request. Only emit the update event for incomplete entries.
Other changes:
- Make DataEntry light as event payload by making all the fields
optional
- Add new required fields to the activity DataEntry
- Add collectibles.ManagerInterface to aid testing
Note: this PR keeps compatibility with current master by always
providing non-optional multi-transaction ID. The TODO will be executed
before merging the status-desktop PR.

Updates status-desktop #11597
Balance history was not checked for all chains if no history on
some chain.
Removed `SetInitialRange` from wallet API as internal implementation.
This method was called on adding a brand new Status account to initialize
blocks_range table to avoid transfers history checks.
Mainly refactor API to have control on pending_transactions operations.
Use the new API to migrate the multi-transaction ID from to transfers
in one SQL transaction.
The refactoring was done to better mirror the purpose of pending_transactions
Also:
- Externalize TransactionManager from WalletService to be used by
other services
- Extract walletEvent as a dependency for all services that need to
propagate events
- Batch chain requests
- Remove unused APIs
- Add auto delete option for clients that fire and forget transactions
Updates status-desktop #11754
Added a unit test for changing app and wallet DBs passwords.
Refactored geth_backend to simplify and allow wallet db password changing.
Fixed opening database with wrong password.
interface for initializing db, which is implemented for appdatabase and
walletdatabase. TBD for multiaccounts DB.
Unified DB initializion for all tests using helpers and new interface.
Reduced sqlcipher kdf iterations for all tests to 1.
The only place where appDB is used in wallet is activity,
which refers to `keycards_accounts` table. So a temporary
table `keycards_accounts` is created in wallet db and updated
before each activity query.
Adding new smart contracts and generated go files.
Deploy token owner function and master token address getter.
Adding deployer and privilegesLevel columns to community_tokens table.
Passing addressFrom to API calls.
Issue #11250
1) Only fetch history for networks that match test mode enabled
* Trade Off: it will be only refetch in 12 hours so changing test mode won't trigger a refetch until app is restarted or 12 hours.
I think it is ok as change test mode is not a common use case
2) Do not consider networks that are enabled or not as this can be change more often than every 12 hours
Add wallet events feed to TransactionManager and send pending changed
events on add and delete
Also
- Remove hardcoded values in the filter query
- Small improvement to query
Updates status-desktop #11233
This fixes returning address identity after that was changed by
the real to/from fix. Previously the address was wrongly used as from
Updates status-desktop #11233
Added test to validate the fix
Also change JOIN to LEFT JOIN between `multi_transactions` and `transactions` table so that we return all entries from `multi_transactions` table even if there is no matching entry in `transactions` table, which might be the case for multi transactions that that could not be detected. This will postpone the error case until we get into details of the multi transaction.
Updates status-desktop #11233
Implement activity.Scheduler to serialize and limit the number of
calls on the activity service. This way we protect form inefficient
parallel queries and easy support async and rate limiting based on the
API requirements.
Refactor the activity APIs async and use the Scheduler for managing
the activity service calls configured with one of the two rules: cancel
ignore.
Updates status-desktop #11170
Main changes:
- Refactor activity API to propagate token identities.
- Extend service to convert token identities to symbols for filtering
multi-transaction
- Filter transfers, pending_transactions and multi-transactions based
on the provided token identities
- Return involved token identities in activity API
- Test token filtering
Also:
- Fixed calling cancel on a filer activity completed task to release
resources
Notes:
- Found limitations with the token identity which complicates things
by not allowing to filter by token groups (like token-code does)
Updates status-desktop #11025
The new API returns all known recipients of a wallet, by
sourcing transfers, pending_transactions and multi_transactions tables
The API is synchronous. Future work will be to make it async.
In some corner cases, when watching a famous wallet, it can
be that there are too many recipients to be returned in one go. Offset
and limit can be used to paginate through the results.

Issue #10816
fetch strategy:
Before:
- block fetching commands for different accounts were in the same wait
group, making them dependent on each iteration.
- transfers loading command was checking database for new unloaded
blocks on timeout and was in the same wait group with block fetching, so
it was often blocked until all block fetching commands finish for
iteration.
Now:
- block fetching commands run independently for each account
- transfers fetching command is run once on startup for unloaded blocks
from DB
- fetch history blocks commands are launched once on startup for
accounts with no full history loaded
- transfers are loaded on each iteration of block range check
without waiting for all ranges to be checked
Refactor the filter interface to be an async call which returns
the result using a wallet event
A call to the filter API will cancel the ongoing filter and receive
an error result event
Closes status-desktop #10994
Main changes:
- extend DB query include status for transactions and pending_transactions
- extend DB query to aggregate data from complex activity entries
- extend tests to include the new status values
Other changes:
- Improve tests with mocked addresses in DB to have a true to/from state
Update status-desktop #10746
Extended the migration process with a generic way of applying custom
migration code on top of the SQL files. The implementation provides
a safer way to run GO code along with the SQL migrations and possibility
of rolling back the changes in case of failure to keep the database
consistent.
This custom GO migration is needed to extract the status from
the JSON blob receipt and store it in transfers table.
Other changes:
- Add NULL DB value tracking to JSONBlob helper
- Index status column on transfers table
- Remove unnecessary panic calls
- Move log_parser to wallet's common package and use to extract token
identity from the logs
Notes:
- there is already an index on transfers table, sqlite creates one for
each unique constraint therefore add only status to a new index
- the planned refactoring and improvements to the database have been
postponed due to time constraints. Got the time to migrate the data
though, extracting it can be done later for a more efficient
implementation
Update status-desktop #10746
- reverted a change that stopped looking for ERC20 transfers if no nonce
and balance change found within a block range for ETH
- implemented sending EventRecentHistoryReady event at a proper time
- moved EventFetchingRecentHistory event to Strategy type as it does not make
sense to send this event in loop
- moved iterating through blocks logic to inside of `loadTransfers` command, which
now accepts a block range.
- reuse `uniqueHeaders` function in commands.go
- clean up
Updates #10246
- old `accounts` table is moved/mapped to `keypairs` and `keypairs_accounts`
- `keycards` table has foreign key which refers to `keypairs.key_uid`
- `Keypair` introduced as a new type
- api endpoints updated according to this change
It uses the current data only and doesn't extend with new types or
include new features in activity sources DBs.
Major changes:
- Partially filter by chain IDs
- Partially filter by Status if it is the case
- Partially filter by token types
- Filter by counterparty addresses
- Use wallet accounts for TO/FROM instead of filters
Closes: #10634
This commit does a few things:
1) Extend create/import account endpoint to get wallet config, some of
which has been moved to the backend
2) Set up a loop for retrieving balances every 10 minutes, caching the
balances
3) Return information about which checks are not passing when trying to
join a token gated community
4) Add tests to the token gated communities
5) Fixes an issue with addresses not matching when checking for
permissions
The move to the wallet as a background task is not yet complete, I need
to publish a signal, and most likely I will disable it before merging
for now, as it's currently not used by desktop/mobile, but the PR was
getting to big
were stored in cache by pointers, which caused falsy cache hits in loop
because pointers with same address were created for different block
numbers. Now cache uses block numbers of uint64 as key, which can
overflow but it is not a problem since we use this cache for values
comparison, not as user data.
Fix crash on nil pointer in log.
Remove some unused code.
Protect nonceRanges with mutex while reading.
Updates #10246
Add the possibility of retrieving the metadata of wallet activity based
on the given filter criteria.
Current implementation relies that after fetching the metadata, user
will follow up with more requests for details. However, after some
experimenting I'm considering extracting all required information
for the summary viewing while filtering. This way there will be no
need for another batch requests for transfers, multi-transactions and
pending transactions to show the summary. Only when user wants to see
the details for one will specifically request it.
For this first prototype, the filter criteria is limited to:
- time
- type
- addresses
Major changes:
- Add the filter definition to be used in propagating the filter
information
- Add GetActivityEntries API to return the list of activity entries
for the given addresses/chainIDs by a view in the complete list
- GetTransfersForIdentities to batch retrieve further details of the
transfers
- GetPendingTransactionsForIdentities to batch retrieve further details
of the pending transactions
- Added a new package testutils for tests.
- Added tests

Add history.exchange sub-package with following responsibilities
- fetch and caches daily exchange rates for tokens
- Partial update if missing form yesterday back
- Implement all time fetching special case
- Fetches the price of the token after merging entries for the selected
chains
history.service package changes
- Return ValuePoint instead of DataPoint
- Value point contains the value in fiat as float64 instead
- Convert merged values from tokens balance (wei) to fiat
Other changes
- Move start/stop balance history to startWallet/stopWallet
- Move cryptocompare to thirdparty package to avoid recursive import
- Rename DataPoint.Value to DataPoint.Balance
- Don't merge entries for single chain
This commit fixes an issue where when accepting a contact request
the other end would display an extra notification.
It also changes WaitOnResponse to collect results. This should make
tests less flaky, since sometimes messages are processed in different
batches.
Now we need to be though exact on what we expect from the response (i.e
use == instead of >, otherwise the same behavior applies)
This uncovered a couple of issues with messenger.Merge, so I have moved
the struct to use a map based collection instead of an array.
This change improves on the previous implementation which used
the block number that doesn't work with incompatible blockchains e.g. L1 vs. L2
Closes: #9205
Extends wallet module with the history package with the following
components:
BalanceDB (balance_db.go)
- Keeps track of balance information (token count, block, block timestamp)
for a token identity (chain, address, currency)
- The cached data is stored in `balance_history` table.
- Uniqueness constrained is enforced by the `balance_history_identify_entry`
UNIQUE index.
- Optimal DB fetching is ensured by the `balance_history_filter_entries`
index
Balance (balance.go)
- Provides two stages:
- Fetch of balance history using RPC calls (Balance.update function)
- Retrieving of cached balance data from the DB it exists (Balance.get
function)
- Fetching and retrieving of data is done for specific time intervals
defined by TimeInterval "enumeration"
- Update process is done for a token identity by the Balance.Update function
- The granularity of data points returned is defined by the constant
increment step define in `timeIntervalToStride` for each time interval.
- The `blocksStride` values have a common divisor to have cache hit
between time intervals.
Service (service.go)
- Main APIs
- StartBalanceHistory: Regularly updates balance history for all
enabled networks, available accounts and provided tokens.
- GetBalanceHistory: retrieves cached token count for a token identity
(chain, address, currency) for multiple chains
- UpdateVisibleTokens: will set the list of tokens to have historical
balance fetched. This is a simplification to limit tokens to a small
list that make sense
Fetch balance history for ECR20 tokens
- Add token.Manager.GetTokenBalanceAt to fetch balance of a specific
block number of ECR20.
- Add tokenChainClientSource concrete implementation of DataSource
to fetch balance of ECR20 tokens.
- Chose the correct DataSource implementation based on the token
"is native" property.
Tests
Tests are implemented using a mock of `DataSource` interface used
to intercept the RPC calls.
Notes:
- the timestamp used for retrieving block balance is constant

Sometimes eth_getBlockByNumber returns txs with chainId which is not
equal to chanin's id. That caused an error and tx fetching was
interrupted. From now on such txs will be skipped.
- avoid making RPC request for `zero - zero` range
- avoid checking of nonce for a lower block in the range if it is zero
in a higher block
- on `wallet_getTransfersByAddress` scanning of history is skipped if
zero block is already reached
- no need to fetch block num before fetching token balances
- old existing ranges are merged when wallet service is started
- a new range is merged with an existing one if possible
This will decrease the number of entries in blocks_range table as
currently it can grow indefinitely (@flexsurfer reported 23307 entries).
This change is also needed for further optimisations of RPC usage.
- Wallet service is not started on foreground event on status-go side
anymore, it leaves a client side opportunity to decide whether new
blocks should be watched.
- `watchNewBlocks` parameter is added to `StartWallet`.
- Some requests are removed/moved to the place where they are necessary.
If one request failed, the whole batch would fail.
This caused issue as one of the contract is constantly returning an
error now, and essentially there was not way to fetch balance.
Also extend the timeout to 20s as we throw 165 request to Infura in one
go and it takes its time to reply to those, although it seems like we
should batch them on our side instead of sending them all cuncurrently.
StartWallet was called before service initialization.
After the recent changes this call was moved after initialization, but
the geth system automatically start services.
This meant that `IsStarted()` returned true, although the reactor was
not started, and only after calling `StopWallet()` and `StartWallet()`
again the system would reach the right state.
This commit changes the behavior so that we only check whether the
reactor has been started when calling `IsStarted()` and we allow
multiple calls to `Start()` on the signal service, which won't return an
error (it's a noop if callled multiple times).
- unused API methods are removed
- some unusued code is removed too
- API docs are updated
That's just a portion of clean up that should be done,
but the rest of it will probably happen in different PR
with changes to the way how we watch to chain updates.
- In order to avoid handling of the reorganized blocks we use an offset
from the latest known block when start listening to new blocks. Before
this commit the offset was 15 blocks for all networks. This offset is
too big for mainnet and causes noticeable delay of marking a transfer as
confirmed in Status (comparing to etherscan). So it was changed to be 5
blocks on mainnet and is still 15 blocks on other networks.
- Also before this commit all new blocks were handled one by one with
network specific interval (10s for mainnet), which means that in case of
lost internet connection or application suspension (happens on iOS)
receiving of new blocks would be paused and then resumed with the same
"speed" - 1 blocks per 10s. In case if that pause is big enough the
application would never catch up with the latest block in the network,
and this also causes the state of transfers to be delayed in the
application. In this commit in case if there was more than 40s delay
after receiving of the previous block the whole history in range between
the previous received block and ("latest"-reorgeSafetyDepth) block is
checked at once and app catches up with a recent state of the chain.
*** How it worked before this PR on multiaccount creation:
- On multiacc creation we scanned chain for eth and erc20 transfers. For
each address of a new empty multiaccount this scan required
1. two `eth_getBalance` requests to find out that there is no any
balance change between zero and the last block, for eth transfers
2. and `chain-size/100000` (currently ~100) `eth_getLogs` requests,
for erc20 transfers
- For some reason we scanned an address of the chat account as well, and
also accounts were not deduplicated. So even for an empty multiacc we
scanned chain twice for each chat and main wallet addresses, in result
app had to execute about 400 requests.
- As mentioned above, `eth_getBalance` requests were used to check if
there were any eth transfers, and that caused empty history in case
if user already used all available eth (so that both zero and latest
blocks show 0 eth for an address). There might have been transactions
but we wouldn't fetch/show them.
- There was no upper limit for the number of rpc requests during the
scan, so it could require indefinite number of requests; the scanning
algorithm was written so that we persisted the whole history of
transactions or tried to scan form the beginning again in case of
failure, giving up only after 10 minutes of failures. In result
addresses with sufficient number of transactions would never be fully
scanned and during these 10 minutes app could use gigabytes of
internet data.
- Failures were caused by `eth_getBlockByNumber`/`eth_getBlockByHash`
requests. These requests return significantly bigger responses than
`eth_getBalance`/`eth_transactionsCount` and it is likely that
execution of thousands of them in parallel caused failures for
accounts with hundreds of transactions. Even for an account with 12k
we could successfully determine blocks with transaction in a few
minutes using `eth_getBalance` requests, but `eth_getBlock...`
couldn't be processed for this acc.
- There was no caching for for `eth_getBalance` requests, and this
caused in average 3-4 times more such requests than is needed.
*** How it works now on multiaccount creation:
- On multiacc creation we scan chain for last ~30 eth transactions and
then check erc20 in the range where these eth transactions were found.
For an empty address in multiacc this means:
1. two `eth_getBalance` transactions to determine that there was no
balance change between zero and the last block; two
`eth_transactionsCount` requests to determine there are no outgoing
transactions for this address; total 4 requests for eth transfers
2. 20 `eth_getLogs` for erc20 transfers. This number can be lowered,
but that's not a big deal
- Deduplication of addresses is added and also we don't scan chat
account, so a new multiacc requires ~25 (we also request latest block
number and probably execute a few other calls) request to determine
that multiacc is empty (comparing to ~400 before)
- In case if address contains transactions we:
1. determine the range which contains 20-25 outgoing eth/erc20
transactions. This usually requires up to 10 `eth_transactionCount`
requests
2. then we scan chain for eth transfers using `eth_getBalance` and
`eth_transactionCount` (for double checking zero balances)
3. we make sure that we do not scan db for more than 30 blocks with
transfers. That's important for accounts with mostly incoming
transactions, because the range found on the first step might
contain any number of incoming transfers, but only 20-25 outgoing
transactions
4. when we found ~30 blocks in a given range, we update initial
range `from` block using the oldest found block
5. and now we scan db for erc20transfers using `eth_getLogs`
`oldest-found-eth-block`-`latest-block`, we make not more than 20 calls
6. when all blocks which contain incoming/outgoing transfers for a
given address are found, we save these blocks to db and mark that
transfers from these blocks are still to be fetched
7. Then we select latest ~30 (the number can be adjusted) blocks from
these which were found and fetch transfers, this requires 3-4
requests per transfer.
8. we persist scanned range so that we know were to start next time
9. we dispatch an event which tells client that transactions are found
10. client fetches latest 20 transfers
- when user presses "fetch more" button we check if app's db contains next
20 transfers, if not we scan chain again and return transfers after
small fixes
Wallet database refactored so that every query ensures isolation by the network id.
Network id provided when database object is created, thus it is transparent to other parts
of the wallet module.
Additionally every uniqueness index is changed to ensure that it doesn't prevent adding
object with same id but from a different network.
* Store tx and receipt in db and cast it to TransferView on read
* Store Log instead of log index
* Use contract from log and bring back address field
* Add tx status and id fields
[services/wallet] Several changes in API after feedback
- Timestamp from block header stored in blocks table and added to each transfers
- From field is computed from signature to offload this computation from client side
- `history` event is added back, so that client can ignore historical blocks when watching
only for new blocks
- block number and timestamp are marshalled in hex. consistent with ethereum data structures
