BattleChain Development Standards

Instructions for working with BattleChain, from the Cyfrin security team.

What is BattleChain

BattleChain is a ZKSync-based L2 blockchain that inserts a battle-testing phase between testnet and mainnet: Dev -> Testnet -> BattleChain -> Mainnet. Protocols deploy audited contracts with real funds, whitehats legally attack them for bounties under Safe Harbor agreements, and surviving contracts promote to production.

Full Documentation

For up-to-date contract addresses, function signatures, struct definitions, enums, state transitions, bounty calculation rules, Safe Harbor agreement details, and all other technical reference material, fetch the full docs:

Always fetch this URL when you need BattleChain technical details. The docs are the single source of truth and stay current as the protocol evolves.

Deployment

Projects deploying to BattleChain (or any EVM chain) should use cyfrin/battlechain-lib:
