Is there any way to integrate the current protocol-kit with viem.sh?, I only see ethers-web3 adapters

[guillermoriv]

I was just wondering if somehow I could create an adapter or if this is something that you guys are planning to do under viem.sh

@guillermoriv I found a way in wagmi documentation to get the "Signer" (ethers) when you have a "WalletClient" (viem). With the Signer you can create the adapter.

https://wagmi.sh/core/ethers-adapters#wallet-client--signer

I know this is not a solution, because you should install ethers, but I think could be a way to handle this moment of migrations from ethers to viem

thanks man, will take a look on this!

I've started developing a Safe library for viem.

https://piggybank.stauro.dev

Example usage for transaction proposal:

import { http, createPublicClient, parseEther, createWalletClient, Hex } from 'viem'
import { goerli } from 'viem/chains'
import { publicSafeActions, walletSafeActions } from '@stauro/piggybank/actions'
import { EIP3770Address, OperationType } from '@stauro/piggybank/types'
import { ApiClient } from '@stauro/piggybank/api'
import { privateKeyToAccount } from 'viem/accounts'

const safeAddress = process.env.SAFE_ADDRESS as EIP3770Address

const publicClient = createPublicClient({
  transport: http(),
  chain: goerli,
}).extend(publicSafeActions(safeAddress))

const walletClient = createWalletClient({
  transport: http(),
  chain: goerli,
  account: privateKeyToAccount(process.env.PK as Hex),
}).extend(walletSafeActions(safeAddress))

const txData = {
  to: process.env.SAFE_TO as EIP3770Address,
  value: parseEther('0.001'),
  operation: OperationType.Call,
  gasPrice: await publicClient.getGasPrice(),
}

const safeTxGas = await publicClient.estimateSafeTransactionGas(txData)

const baseGas = await publicClient.estimateSafeTransactionBaseGas({ ...txData, safeTxGas })

const nonce = await publicClient.getSafeNonce()

const safeTxHash = await publicClient.getSafeTransactionHash({ ...txData, safeTxGas, baseGas, nonce })

const senderSignature = await walletClient.generateSafeTransactionSignature({ ...txData, nonce, safeTxGas, baseGas })

const apiClient = new ApiClient({ url: 'https://safe-transaction-goerli.safe.global', safeAddress })

await apiClient.proposeTransaction({
  safeTransactionData: { ...txData, safeTxGas, baseGas, nonce },
  senderAddress: walletClient.account.address,
  safeTxHash,
  senderSignature,
  chainId: goerli.id,
  origin: 'Piggybank',
  nonce,
})
