Installation

Install the package with yarn or npm:

yarn install
npm install

Build

Build the package with yarn or npm:

yarn build
npm run build

Tests

Create a .env file with environment variables. You can use the .env.example file as a reference.

Test the package with yarn or npm:

yarn test
npm run test

Initialization

Initialize the SafeApiKit

import SafeApiKit from '@safe-global/api-kit'

const safeService = new SafeApiKit({
  chainId: 1n,
  // Optional. txServiceUrl must be used to set a custom service. For example on chains where Safe doesn't run services.
  txServiceUrl: 'https://safe-transaction-mainnet.safe.global'
})

API Reference

estimateSafeTransaction

Estimates the safeTxGas for a given Safe multi-signature transaction.

const estimateTx: SafeMultisigTransactionEstimateResponse =
  await safeService.estimateSafeTransaction(safeAddress, safeTransaction)

proposeTransaction

Creates a new multi-signature transaction and stores it in the Safe Transaction Service.

const pendingTxs: SafeMultisigTransactionListResponse = await safeService.getPendingTransactions(
  safeAddress
)

const pendingTxs: SafeMultisigTransactionListResponse = await safeService.getPendingTransactions(
  safeAddress,
  currentNonce

  safeAddress
)

const allTxsOptions: AllTransactionsOptions = {
  executed,
  queued,
  trusted
}
