Interactive form — coming next session

Two-phase async UI in progress. The precompile itself is 0x0000000000000000000000000000000000000819 and live on testnet — use the canonical Solidity / viem code below to integrate from your own contract.

ABI summary

  ModalInput[] inputs,

Callback pattern

Two-phase precompiles deliver results via AsyncDelivery at 0x5A16214fF555848411544b005f7Ac063742f39F6 calling your contract’s callback. Always verify msg.sender == ASYNC_DELIVERY to prevent injection.

function onLongRunningResult(bytes32 jobId, bytes calldata result) external {
    require(msg.sender == ASYNC_DELIVERY, "unauth");
    // ... decode result based on this precompile's response ABI
}
