Cross-Chain Bridge

AIHI Network implements a native cross-chain bridge built upon the Optimism Standard Bridge framework, enabling secure and permissionless transfers of ETH and ERC-20 tokens between Ethereum and the AIHI Chain.

The bridge adopts a lock-and-mint / burn-and-unlock model:

Ethereum → AIHI: Users lock ETH or ERC-20 tokens on L1 and receive minted AIHI-native tokens on L2. Transfers are confirmed in real time, typically within 5–10 seconds.

AIHI → Ethereum: Users burn AIHI-native tokens on L2 to initiate withdrawals. Following a 7-day dispute period (per OP Stack security model), the original tokens are unlocked on L1.

Key features:

Bi-directional ETH and token transfers

Default sender = receiver to ensure simplicity and security

Fixed-value gas deduction handled automatically during bridging

Real-time status updates on bridge interface and explorer

Transaction hash verification for each bridge event

Full compatibility with Optimism Bridge contracts

Planned extensions include bridging to additional OP Stack chains (e.g. Base, Zora), other Ethereum L2s (e.g. Arbitrum, zkSync), and eventually Cosmos/Polkadot via unified cross-chain messaging protocols.
