GMEngine

Generate visible, honest on-chain activity across multiple EVM networks. Daily GM, contract deployments, NFT mints, streaks, and automated relaying. This repository contains Solidity smart contracts used on GMEngine.xyz platform. They are designed for daily on-chain activity (GM, deploy, mint, streaks) and optional relayer automation using EIP-712 signatures.

Contracts

• GMContract.sol

  • Daily GM tracker with streaks and totals.
  • Supports manual GM (gmSelf()) and AutoGM relayed GM.
  • Authorization is based on EIP-712 messages { user, nonce, deadline }.

• DeployFactory.sol

  • Daily deployment streak tracker.
  • Supports manual deploy (deploySelf()) and AutoDeploy relayed deploy.
  • Deploys user-owned minimal contracts on demand.

• MinimalContract.sol

  • Minimal per-user contract used for explorer visibility.
  • Stores owner, deployedAt.
  • Provides interaction method: a free ping() that increments counters and emits Ping.

• MinimalContractPayable.sol
