This is an Ethers@v6 Signer that can be used together with Ethers.js applications, using AWS KMS as the key storage. For GCP KMS look here

Getting Started

npm i @dennisdang/ethers-aws-kms-signer

import { AwsKmsSigner } from "ethers-aws-kms-signer";

const kms = new KMSClient({
  region: "us-east-1",
  credentials: {
    accessKeyId: "x",
    secretAccessKey: "y",
    sessionToken: "z", // required if using temporary credentials
  },
});

const provider = new JsonRpcProvider("rpc endpoint");
const signer = new AwsKmsSigner(
  "db3e7082-2b67-49a8-a7e1-092d52a1b2b8",
  kms,
  provider
);
const SomeContract = new Contract(
  "0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0",
  yourJsonAbi,
  signer
);

const tx = await SomeContract.mint("to-address", tokenId);

await tx.wait();

console.log(tx);
