Wallet service API

Wallet service provides RPC API for checking transfers history and other methods related to wallet functionality. To enable service two values need to be changed in the config:

  1. Set Enable to true in WalletConfig
{
  "WalletConfig": {
    "Enabled": true,
  }
}
  1. And expose wallet API with APIModules
{
  APIModules: "eth,net,web3,peer,wallet",
}

API

wallet_getTransfersByAddress

Returns avaiable transfers in a given range.

Parameters

  • address: HEX - ethereum address encoded in hex
  • toBlock: BIGINT - end of the range. if nil query will return last transfers.
  • limit: BIGINT - limit of returned transfers.
  • fetchMore: BOOLEAN - if true, there are less than limit fetched transfers in the database, and zero block is not reached yet, history will be scanned for more transfers. If false only transfers which are already fetched to the app's database will be returned.

    ],
    "message": "something might be here"
  }
}
  1. new-transfers

Emitted when transfers are detected. In this case block number is a block number of the latest found transfer. Client expected to request transfers starting from received block.

  1. recent-history-fetching

Emitted when history scanning is started.

  1. recent-history-ready

Emitted when history scanning is ended.

  1. fetching-history-error

Emitted when when history can't be fetched because some error. Error's decritption can be found in message field.

  1. non-archival-node-detected

Emitted when the application is connected to a non-archival node.

Flows

Account creation

When a new multiaccount is created corresponding address will not contain any transaction. Thus no point in checking history, it will be empty.

  1. Call wallet_setInitialRange
  2. Call wallet_checkRecentHistory
  3. On recent-history-ready request transactions via wallet_getTransfersByAddress
  4. Repeat wallet_checkRecentHistory in N minutes (currently 20 minutes in status-react for upstream RPC node. If a custom node is used interval can be arbitrary)

Logging into application

  1. Call wallet_checkRecentHistory
  2. On recent-history-ready request transactions via wallet_getTransfersByAddress
  3. Repeat wallet_checkRecentHistory in N minutes (currently 20 minutes in status-react for upstream RPC node. If a custom node is used interval can be arbitrary)

Watching transaction

  1. Call wallet_watchTransaction
  2. On success call wallet_checkRecentHistory
  3. On recent-history-ready request transactions via wallet_getTransfersByAddress
