Send Transactions

In this guide, you will learn how to create Safe transactions, sign them, collect the signatures from the different owners, and execute them.

For more detailed information, see the Starter Kit Reference.

Prerequisites

Install dependencies

First, you need to install some dependencies.


_10
pnpm add @safe-global/starter-kit

Steps

Imports

Here are all the necessary imports for this guide.


_10
import { createSafeClient } from '@safe-global/sdk-starter-kit'

Create a signer

Firstly, you need to get a signer, which will be the owner of a Safe account after it's deployed.

This example uses a private key, but any way to get an EIP-1193 compatible signer can be used.


_10
const SIGNER_ADDRESS = // ...
_10
const SIGNER_PRIVATE_KEY = // ...
_10
const RPC_URL = 'https://rpc.ankr.com/eth_sepolia'

Initialize the SafeClient

When deploying a new Safe account, you need to pass the configuration of the Safe in the safeOptions property. The Safe account is configured with your signer as the only owner in this case.


_10
const safeClient = await createSafeClient({
_10
provider: RPC_URL,
_10
signer: SIGNER_PRIVATE_KEY,
_10
safeOptions: {
_10
owners: [SIGNER_ADDRESS],
_10
threshold: 1
_10
}
_10
})

Create a Safe transaction

Create an array of Safe transactions to execute.


_10
const transactions = [{
_10
to: '0x...',
_10
data: '0x',
_10
value: '0'
_10
}]

Send the Safe transaction

If you configured your Safe with threshold equal to 1, calling the send method will execute the Safe transaction. However, if the threshold is greater than 1 the other owners of the Safe will need to confirm the transaction until the required number of signatures are collected.


_10
const txResult = await safeClient.send({ transactions })
_10
_10
const safeTxHash = txResult.transactions?.safeTxHash

Confirm the Safe transaction

If the Safe transaction needs to be confirmed by other Safe owners, call the confirm method from a new SafeClient instance initialized with each of the signers that need to confirm it.


_10
const newSafeClient = await createSafeClient({
_10
provider: RPC_URL,
_10
signer,
_10
safeAddress: '0x...'
_10
})

Finally, retrieve all the pending Safe transactions from the Safe Transaction Service and confirm the one you just created with each missing owner.


_10
const pendingTransactions = await newSafeClient.getPendingTransactions()
_10
_10
for (const transaction of pendingTransactions.results) {
_10
if (transaction.safeTxHash !== safeTxHash) {
_10
return
_10
}
_10
_10
const txResult = await safeClient.confirm({ safeTxHash })
_10
}

Recap and further reading

After following this guide, you are able to deploy new Safe accounts and create, sign, and execute Safe transactions with the Starter Kit.
