API Side

See using the sdk for more details on how features plug into the SDK and the API interface in the type declaration.

If you're building a feature that needs to write transaction logs or account states you can also use the batching feature of blockchain-metadata, which will only emit once after all updates are processed. Depend on the blockchainMetadata node and use the batch method to queue up updates:

await blockchainMetadata
  .batch()
  .updateAccountState({
    assetName: 'bitcoin',
    walletAccount: 'exodus_0',
    newData: { cursor: 'some cursor' },
  })
  .updateAccountState({
    assetName: 'ethereum',
    walletAccount: 'exodus_0',
    newData: { cursor: 'some cursor' },
  })
  .updateTxs({
    assetName: 'ethereum',
    walletAccount: 'exodus_0',
    txs: [{ id: '123', confirmations: 42 }],
  })
  .commit()
