PROBLEMThe Challenge

Required a verifiable command execution path for cross-chain flows, plus supporting modules (auth, gas, deposits) as part of the end-to-end system.

✓

SOLVEDThe Solution

Integrated the CGP contract suite (Gateway/AuthWeighted/GasService/DepositService) with weighted multisig auth, gas payment/refund, and CREATE2-based deposits. Implemented a Beatoz relayer that monitors on-chain events and executes verified commands, supported by deploy scripts and tests.

Technical Deep Dive

Overview

  • ▶Solo-built cross-chain integration between Beatoz EVM and Axelar CGP.
  • ▶Includes CGP contracts (Gateway/Auth/Gas/Deposit) and an event-driven relayer.

Key Components

CGP Contract Layer

  • ▶Gateway (execute command batches) + AuthWeighted (weighted multisig, epoch/validator set) + GasService + DepositService (CREATE2 deposits).

Relayer (Event Monitoring → Command Execution)

  • ▶Monitors source-chain events and executes destination-chain commands.
  • ▶Built with batching/direct-RPC style optimizations to reduce overhead while preserving reliability.

Operational Focus

  • ▶Cross-chain systems are failure-first: idempotency, retries, and observability are first-class concerns.
