Using System Contracts

These system contracts follow similar interfaces to other Ethereum Layer 2 solutions. You can interact with these contracts using standard Ethereum libraries and tools.

Example: Bridging ETH from L1 to L2

// On Sepolia (L1)
IL1StandardBridge bridge = IL1StandardBridge(0xe9a531a5d7253c9823c74af155d22fe14568b610);

// Deposit ETH to L2
bridge.depositETH{value: amount}(
    minGasLimit,
    emptyBytes  // No additional data
);

Example: Sending a Message from L2 to L1

// On RISE Testnet (L2)
IL2CrossDomainMessenger messenger = IL2CrossDomainMessenger(0x4200000000000000000000000000000000000007);

// Send message to L1
messenger.sendMessage(
    targetL1Address,
    abi.encodeWithSignature("someFunction(uint256)", value),
    minGasLimit
);
