FHE Inference

Encrypted ML

Run inference on CKKS-encrypted tensors. Plaintext never leaves the user.

Interactive form — coming next session

Two-phase async UI in progress. The precompile itself is 0x0000000000000000000000000000000000000807 and live on testnet — use the canonical Solidity / viem code below to integrate from your own contract.

ABI summary

(
  bytes encryptedTensor,      // CKKS-encrypted input
  string modelName,
  bytes evaluationKeyRef,     // StorageRef to eval key
  uint256 layerCount,
  address executor,
  ...19 fields total
)
→ delivers CKKS-encrypted result (only key holder can decrypt)

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