Understanding Bridge Mechanics

Token Bridging Process

graph LR
    A[Source Chain] -->|Lock Tokens| B[Bridge Contract]
    B -->|Notify| C[Bridge Service]
    C -->|Release| D[Target Chain]

The bridge operates through a lock-and-mint mechanism:

  1. Tokens are locked in the source chain's bridge contract

  2. Bridge service verifies the lock transaction

  3. Equivalent tokens are released on the target chain

Native Currency Bridging

When bridging native currencies:

  • ETH → æternity: Receives wETH (AEX-9 token)

  • AE → Ethereum: Receives wAE (ERC-20 token)

Security and Verification

The bridge maintains a 1:1 ratio between locked and released assets. You can verify this through:

  • Smart contract inspection on both chains

  • Public contract addresses

  • Real-time bridge statistics
