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
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
Closes status-desktop: #8175, #8226, #8862
* feat(@desktop/wallet): added iso4217 library for fiat currency display decimals
* feat(@desktop/wallet): added token peg info and use numbers for token market values
* feat(@desktop/wallet): added
* feat(@desktop/wallet): added iso4217 library for fiat currency display decimals
* feat(@desktop/wallet): added token peg info and use numbers for token market values
* feat(@desktop/wallet): extend wallet api to fetch prices in multiple currencies
* chore(@desktop/wallet): rename token peg field for clarity
Add functionality to sample and retrieve balance history and cache
it in memory for the current transfer controller.
The end of the balance history is snapped at twice per day to
avoid having to query the blockchain again for each fetching within
12 hours interval
The functionality will be extended with DB caching, API call batching,
"smarter" cache hitting and syncing between devices
Updates: #7662
Main changes:
- Extend saved addresses DB with sync info: sync timestamp, update timestamp
and soft removed flag
- Create custom protobuf message payload to sync saved addresses
- Cleanup saved addresses on each start of messenger, by deleting
soft removed older entries
- Sync all saved addresses on Messenger.SyncDevices calls
- Sync particular changes to saved addresses
- Add SavedAddressManager instance to messenger
- Note, can't find a clean way to pass the SavedAddressManager to the
messenger, so we create another one
- Add tests for sync and new DB API
Closes: #7229
Remove Favourites APIs and update the saved address APIs
Added up migration scripts that move the favourites from the old table
to the saved_addresses table with true flag and then drop the favourites table.
Required by #6546
Added functionality to find target address when 6th param in path is added
for ex: "m'/44'/60'/0'/0/500" reperents the Address at the 500th index
Added a api to get the Address derived from a private key
* feat: enable wallet without network binding
* feat: make transfer network aware
* feat: allow to pass initial networks via config
* fix: nil check and feed
* feat: Add documentation with better function name
* fix: do not init the manager more than once
* fix: PR feedbacks
* Bump version
* Update Jenkinsfile.tests
* Convert int to string
