How It Works

Example: Bridging ETH (Ethereum) to USDC (Arbitrum)

1. User Initiates Bridge

   • Inputs:

     • Source token: ETH (Ethereum)

     • Destination token: USDC (Arbitrum)

     • Amount

     • Encrypted destination address

2. Route Creation

   • Relayers are selected randomly from the active node pool.

   • Path encrypted using public keys of selected nodes.

3. Asset Lock

   • ETH is locked in the TOR smart contract on Ethereum.

   • A zkSNARK proof is generated, asserting lock conditions without revealing details.

4. Hops Execute

   • Each node decrypts one layer and forwards to the next.

   • Final node sees the destination chain and executes a mint or release.

5. USDC Delivered

   • Shielded transaction executed on Arbitrum.

   • Recipient receives USDC privately, with transaction metadata obfuscated.
