Wallet

Wallet service starts a loop that watches for new transfers (eth and erc20). To correctly start the 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.

Returns

Objects in the same format.

wallet_getTokensBalances

Signals

Two signals can be emitted:

  1. newblock signal

Emitted when transfers from new block were added to the database. In this case block number if the number of this new block. Client expected to request transfers starting from received block.

{
  "type": "wallet",
  "event": {
    "type": "newblock",
    "blockNumber": 0,
    "accounts": [
      "0x42c8f505b4006d417dd4e0ba0e880692986adbd8",
      "0x3129mdasmeo132128391fml1130410k312312mll"
    ]
  }
}
  1. reorg signal.

Emitted when part of blocks were removed. Starting from a given block number all transfers were removed. Client expected to request new transfers from received block and replace transfers that were received previously.

{
  "type": "wallet",
  "event": {
    "type": "reorg",
    "blockNumber": 0,
    "accounts": [
      "0x42c8f505b4006d417dd4e0ba0e880692986adbd8"
    ]
  }
}
  1. history signal

Emmited when historical transfers were downloaded. Block number will refer the first block where historical transfers were found.

{
  "type": "wallet",
  "event": {
    "type": "history",
    "blockNumber": 0,
    "accounts": [
      "0x42c8f505b4006d417dd4e0ba0e880692986adbd8"
    ]
  }
}
