Sign ETH transactions with keys stored in AWS KMS * Free software: MIT * Documentation: ## Features * Sign Transactions ## Video Demo [![Python Ethereum KMS Signer Demo](https://user-images.githubusercontent.com/7620533/135247248-7c3efda3-b8f8-4936-a2b6-363cb05ba513.png)](https://youtu.be/fZ-mtMb2BjY "Python Ethereum KMS Signer Demo") ## Why? In the crypto world, all the assets, tokens, crypto you might own is protected by the secrecy of the private key. This leads to a single point of failure in cases of leaking of private keys or losing keys because of lack of backup or any number of reasons. It becomes even harder when you want to share these keys as an organization among many individuals. Using something like AWS KMS can help with that and can provide full benefits of all the security features it provides. Sigantures can be created without the key ever leaving the AWS's infrastructure and could be effectively shared among individuals. This library provides a simple and an easy-to-use API for using AWS KMS to sign ethereum transactions and an easy integration with `web3.py` making it practical for using KMS to manage your private keys. ## Quickstart ### Get ethereum address from KMS key ```python from ethereum_kms_signer import get_eth_address address = get_eth_address('THE-AWS-KMS-ID') print(address) ``` ### Sign a transaction object with KMS key ```python from ethereum_kms_signer import sign_transaction dai_txn = dai.functions.transfer( web3.toChecksumAddress(to_address.lower()), amount ).buildTransaction( { "nonce": nonce, } ) # Signing the transaction with KMS key signed_tx = sign_transaction(dai_txn, key_id) # send transaction tx_hash = web3.eth.sendRawTransaction(signed_tx.rawTransaction) ``` ### Provisioning AWS KMS key with terraform An `ECC_SECG_P256K1` key can be provisioned using terraform by using the following configuration along with the aws provider. More details can be found on [provider docs]() ```tf resource "aws_kms_key" "my_very_secret_eth_account" { description = "ETH account #1" key_usage = "SIGN_VERIFY" customer_master_key_spec = "ECC_SECG_P256K1" } resource "aws_kms_alias" "my_very_secret_eth_account" { name = "eth-account-1" target_key_id = aws_kms_key.my_very_secret_eth_account.id } ``` ## Examples Few examples can be found [here](https://github.com/meetmangukiya/ethereum-kms-signer/tree/main/examples). ## Credits This package was created with [Cookiecutter](https://github.com/audreyr/cookiecutter) and the [zillionare/cookiecutter-pypackage](https://github.com/zillionare/cookiecutter-pypackage) project template.
