Creating a Link that holds funds is easy. Have a look here how you can create one yourself!
There are two ways of creating a Link. If you are using EthersV5, you can simply call one SDK function to create a Link. If you are not using EthersV5, or want to have more control over the Link creation process, you can call a set of SDK functions.
Create a Link using EthersV5
The 'one function' approach requires you to pass in an EthersV5 signer, together with some basic information of the Link.
plain textimport peanut, { getDefaultProvider } from '@squirrel-labs/peanut-sdk'; import { Wallet } from 'ethersv5'; const chainId = '11155111' // Sepolia const mnemonic = 'announce room limb pattern dry unit scale effort smooth jazz weasel alcohol' async function createLink(): Promise<string | null> { let wallet = Wallet.fromMnemonic(mnemonic) const provider = await getDefaultProvider(chainId) wallet = wallet.connect(provider) const { link, txHash } = await peanut.createLink({ structSigner: { signer: wallet }, linkDetails: { chainId: chainId, tokenAmount: 0.01, tokenType: 0, // 0 for ether, 1 for erc20, 2 for erc721, 3 for erc1155 tokenDecimals: 18, } }) return link } createLink().then((link) => console.log(link))
Create a Link using Signer Agnostic Functions:
You're not using EthersV5, but some other signing library (viem, web3js, wagmi, inhouse etc)? No problem! You will have to prepare the transactions(s), submit the transaction with your wallet, and use the resulting transaction hash to generate the link. The following is an example that does not use a particular signer.
plain textconst chainId = '11155111' // Sepolia const mnemonic = 'announce room limb pattern dry unit scale effort smooth jazz weasel alcohol' async function createLink(): Promise<string | null> { let wallet = Wallet.fromMnemonic(mnemonic) const provider = await getDefaultProvider(chainId) wallet = wallet.connect(provider) const linkDetails = { chainId: chainId, tokenAmount: 0.001, tokenType: 0, // 0 for ether, 1 for erc20, 2 for erc721, 3 for erc1155 tokenDecimals: 18, } const password = await peanut.getRandomString(16) const preparedTransactions = await peanut.prepareDepositTxs({ address: wallet.address, linkDetails, passwords: [password], }) const transactionHashes: string[] = [] for (const unsignedTx of preparedTransactions.unsignedTxs) { const convertedTx = peanut.peanutToEthersV5Tx(unsignedTx) const signedTx = await wallet.sendTransaction(convertedTx) transactionHashes.push(signedTx.hash) } const { links } = await peanut.getLinksFromTx({ linkDetails, passwords: [password], txHash: transactionHashes[transactionHashes.length - 1], }) return links[0] } createLink().then((link) => console.log(link))
