ComPilot Signature Gating provides NexeraID signature-based smart contracts that help on-chain protocols gate access to their smart contracts on a per-transaction basis. This solution enables protocols to enforce KYC and compliance requirements directly at the smart contract level.

Traditional blockchain smart contracts are permissionless by default. ComPilot's signature-based gating system restricts access by requiring users to obtain valid signatures from NexeraID's API before executing transactions.

Key Benefits

No operational costs for updating allowlists
Single source of truth prevents synchronization issues
Privacy preservation - denied transactions never appear on-chain
Flexible compliance based on KYC conditions and transaction inputs

How It Works

The system uses a three-component architecture:

API Endpoint - Provides signatures that authenticate users on-chain
Smart Contract (TxAuthDataVerifier) - Verifies transaction signatures on-chain
SDKs - Simplify integration between applications and the API

Basic Integration

Smart Contract:

import "@nexeraid/sig-gating-contracts/contracts/signers/TxAuthDataVerifier.sol";
 
contract YourProtocol is TxAuthDataVerifier {
    function protectedFunction() external requireTxDataAuth() {
        // Your protected logic here
    }
}

Front-End:

const signatureResponse = await getSignature({
  account: userAddress,
  contractAddress: protocolAddress,
  functionName: "protectedFunction"
});
 
if (signatureResponse.isAuthorized) {
  // Execute signed transaction
}

Deployment Information

Supported Networks: Ethereum, Polygon, Base, Arbitrum, Optimism, BSC/BNB, Avalanche (Mainnet & Testnets)

Use Cases

Compliant DeFi - Restrict access based on KYC status
Gated NFT Minting - Control distribution to verified users
Regulatory Compliance - Meet jurisdiction-specific requirements
Institutional Access - Enterprise-grade access controls
