CRYPTO DEV SIGNER

This package is written because at the time no good solution seemed to exist for solving the following combined requirements and issues:

  • A service has custody of its users' private keys.
  • The are a large number of private keys involved (hundreds of thousands and up).
  • Need to sign transactions conforming to EIP-155, with the ability to arbitrarily specify the "chain id".
  • Do not want to store the keys inside an ethereum node, especially not the one connected to the network.
  • Want to use the "standard" web3 JSON-RPC interface, so that the component can be easily replaced later.
  • Multiple providers don't work on either web3.js and/or web3.py.
  • As a bonus, provide a practical keystore solution for testing in general for web3 projects.

TECHNICAL OVERVIEW

Scripts

When installed with pip/setuptools, this package provides a Unix socket IPC server as crypto-dev-daemon implementing the following web3 json-rpc methods:

  • web3.eth.personal.newAccount
  • web3.eth.personal.signTransaction
  • web3.eth.signTransaction

Classes

The classes and packages provided are:

keystore

  • Keystore: Interface definition
  • ReferenceKeystore: Implements the Keystore interface, with a postgresql backend expecting sql schema as defined in ReferenceKeystore.schema

transaction

  • Transaction: Interface definition.
  • EIP155Transaction: Creates transaction serializations appropriate for EIP155 replay protected signatures. Accepts a web3 format transaction dict as constructor argument together with nonce and optional chainId.

signer

  • Signer: Interface definition. Its signTransaction method expects an object implementing the Transaction interface.
  • ReferenceSigner Implements Signer, accepting a single argument of type Keystore interface.
