Initialization

Instantiate an EthAdapter

First of all, we need to create an EthAdapter, which contains all the required utilities for the SDKs to interact with the blockchain. It acts as a wrapper for web3.js or ethers.js Ethereum libraries.

Depending on the library used by the Dapp, there are two options:

• Create an EthersAdapter instance
• Create a Web3Adapter instance

Once the instance of EthersAdapter or Web3Adapter is created, it can be used in the SDK initialization.

Initialize the SafeApiKit

import SafeApiKit from '@pnsdomains/api-kit'

const safeService = new SafeApiKit({
  txServiceUrl: 'https://safe-transaction-mainnet.safe.global',
  ethAdapter
})

API Reference

getServiceInfo

Returns the information and configuration of the service.

const serviceInfo: SafeServiceInfoResponse = await safeService.getServiceInfo()

getServiceMasterCopiesInfo

Returns the list of Safe master copies.

const masterCopies: MasterCopyResponse = await safeService.getServiceMasterCopiesInfo()

decodeData

Decodes the specified Safe transaction data.

const decodedData = await safeService.decodeData(data)

getSafesByOwner

Returns the list of Safes where the address provided is an owner.

const safes: OwnerResponse = await safeService.getSafesByOwner(ownerAddress)

getSafesByModule

Returns the list of Safes where the module address provided is enabled.

const safes: ModulesResponse = await getSafesByModule(moduleAddress)

getTransaction

Returns all the information of a Safe transaction.

const tx: SafeMultisigTransactionResponse = await safeService.getTransaction(safeTxHash)

getTransactionConfirmations

Returns the list of confirmations for a given a Safe transaction.

const confirmations: SafeMultisigConfirmationListResponse =
  await safeService.getTransactionConfirmations(safeTxHash)

confirmTransaction

Adds a confirmation for a Safe transaction.

const signature: SignatureResponse = await safeService.confirmTransaction(safeTxHash, signature)

getSafeInfo

Returns the information and configuration of the provided Safe address.

const safeInfo: SafeInfoResponse = await safeService.getSafeInfo(safeAddress)

getSafeDelegates

Returns the list of delegates for a given Safe address.

const delegateConfig: GetSafeDelegateProps = {
  safeAddress, // Optional
  delegateAddress, // Optional
  delegatorAddress, // Optional
  label, // Optional
  limit, // Optional
  offset // Optional
}
const delegates: SafeDelegateListResponse = await safeService.getSafeDelegates(delegateConfig)

addSafeDelegate

Adds a new delegate for a given Safe address.

const delegateConfig: AddSafeDelegateProps = {
  safeAddress, // Optional
  delegateAddress,
  delegatorAddress,
  label,
  signer
}
await safeService.addSafeDelegate(delegateConfig)

removeSafeDelegate

Removes a delegate for a given Safe address.

const delegateConfig: DeleteSafeDelegateProps = {
  delegateAddress,
  delegatorAddress,
  signer
}
await safeService.removeSafeDelegate(delegateConfig)

getSafeCreationInfo

Returns the creation information of a Safe.

const safeCreationInfo: SafeCreationInfoResponse = await safeService.getSafeCreationInfo(
  safeAddress
)

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 transactionConfig: ProposeTransactionProps = {
  safeAddress,
  safeTxHash,
  safeTransactionData,
  senderAddress,
  senderSignature,
  origin
}
await safeService.proposeTransaction(transactionConfig)

getIncomingTransactions

Returns the history of incoming transactions of a Safe account.

const incomingTxs: TransferListResponse = await safeService.getIncomingTransactions(safeAddress)

getModuleTransactions

Returns the history of module transactions of a Safe account.

const moduleTxs: SafeModuleTransactionListResponse = await safeService.getModuleTransactions(
  safeAddress
)

getMultisigTransactions

Returns the history of multi-signature transactions of a Safe account.

const multisigTxs: SafeMultisigTransactionListResponse = await safeService.getMultisigTransactions(
  safeAddress
)

getPendingTransactions

Returns the list of multi-signature transactions that are waiting for the confirmation of the Safe owners.

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

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

getAllTransactions

Returns a list of transactions for a Safe. The list has different structures depending on the transaction type.

const allTxs: SafeMultisigTransactionListResponse = await safeService.getAllTransactions(
  safeAddress
)

const allTxsOptions: AllTransactionsOptions = {
  executed,
  queued,
  trusted
}
const allTxs: SafeMultisigTransactionListResponse = await safeService.getAllTransactions(
  safeAddress,
  allTxsOptions
)

getNextNonce

Returns the right nonce to propose a new transaction right after the last pending transaction.

const nextNonce = await safeService.getNextNonce(safeAddress)

getTokenList

Returns the list of all the ERC20 tokens handled by the Safe.

const tokens: TokenInfoListResponse = await safeService.getTokenList()
