Deployed Addresses

​
EVM Chains

All EVM chains use a consistent deployment pattern with deterministic addresses where possible.
Chain ID: 1 (Gasyard ID: 1)

​
Special Networks

Gasyard ID: 5HyperLiquid bridging is managed through Arbitrum infrastructure. Use Gasyard ID 5 as the unique identifier when targeting HyperLiquid.

​
Gateway Contract Interface

The Gateway is the core intent contract. It is non-upgradeable for trust minimization.

​
Key Functions

// Create a bridge intent
function bridgeToken(
    address token,
    uint256 amount,
    uint256 destChainId,
    address destRecipient,
    uint256 minOutput,
    uint256 expiry,
    bytes calldata metadata
) external;

// Execute an intent (solver only)
function executeOrder(
    bytes32 orderId,
    address recipient,
    uint256 amount
) external;

​
Key Events

event OrderCreated(
    bytes32 indexed orderId,
    address indexed sender,
    address token,
    uint256 amount,
    uint256 destChainId,
    address destRecipient,
    uint256 minOutput,
    uint256 expiry,
    bytes metadata
);

event OrderExecuted(
    bytes32 indexed orderId,
    address indexed solver,
    uint256 outputAmount
);

​
Router Interfaces

​
GatewayRouter (Source Chain)

Handles source-side swaps before bridging. 
// Swap input token and bridge
function swapAndBridge(
    address inputToken,
    uint256 inputAmount,
    bytes calldata swapData,
    uint256 destChainId,
    address destRecipient,
    uint256 minOutput,
    uint256 expiry
) external;

// Bridge with native token (ETH)
function bridgeNative(
    uint256 destChainId,
    address destRecipient,
    uint256 minOutput,
    uint256 expiry
) external payable;

​
SolverRouter (Destination Chain)

Handles destination-side swaps after payout. 
// Execute with swap
function executeAndSwap(
    bytes32 orderId,
    address recipient,
    address outputToken,
    bytes calldata swapData
) external;

​
Deposit Address Factory

CREATE2 factory for deterministic deposit addresses, enabling gasless deposits. 
// Generate deposit address for a user
function getDepositAddress(
    address user,
    bytes32 salt
) external view returns (address);

// Deploy and forward deposit
function deployAndForward(
    address user,
    bytes32 salt
) external;

​
Security Features

All contracts implement:

Role-Based Access

Only authorized addresses can execute specific functions

Token Whitelisting

Only approved tokens can be bridged

Replay Protection

Order IDs can only be executed once

Non-Upgradeable Gateway

Core contract cannot be modified after deployment
