xdeployer. Hardhat plugin to deploy your smart contracts across multiple EVM chains with the same deterministic address.

safe-tx-hashes-util. This Bash script calculates the Safe transaction hashes by retrieving transaction details from the Safe transaction service API and computing both the domain and message hashes using the EIP-712 standard.
