Gnosis Safe from backend

[arnaudjnn]

Is it possible to use a Gnosis Safe wallet from the backend (Node.js)? I'm trying to list NFTs using the marketplace pre-build contract.

Thanks

Yes! it's possible. Requires you to instantiate a signer from the @gnosis.pm/safe-ethers-adapters library. Here's a code example:

import { ThirdwebSDK } from "@thirdweb-dev/sdk";
import { ethers, Wallet } from "ethers";
import Safe from "@gnosis.pm/safe-core-sdk";
import { SafeEthersSigner, SafeService } from "@gnosis.pm/safe-ethers-adapters";
import EthersAdapter from "@gnosis.pm/safe-ethers-lib";

// gnosis safe setup
const provider = ethers.getDefaultProvider("rinkeby");
// private key from one of the holders of the safe
const signer = new Wallet(process.env.PKEY as string, provider);
// switch to the service for the chain you want to use
const service = new SafeService(
  "https://safe-transaction.rinkeby.gnosis.io"
);
const ethAdapter = new EthersAdapter({ ethers, signer });
// create a safe instance
const safe = await Safe.create({
  ethAdapter,
  safeAddress: "your_gnosis_safe_address",
});
// create a signer for the safe
const safeSigner = new SafeEthersSigner(safe, service, provider);
// now you can connect to the SDK from the gnosis signer
const sdk = ThirdwebSDK.fromSigner(safeSigner, "rinkeby");

lmk if that works for you

Works well, thank you very much!

Can we add it to the doc here?

Glad it worked, did you have to change anything from that setup?

Great idea to add to the portal, PRs are appreciated! https://github.com/thirdweb-dev/docs
