Protocol Architecture

Designed for zero friction digital dollar commerce.

Track 1 · Universal Naming

Sovereign ₦TAG Registry

Claim permanent identities bound directly to Arc Mainnet USDC addresses. No homoglyphs, no spoofing, and 100% interoperable across wallets, agents, and payment apps.

Track 2 · Zero Gas Token Friction

Pure Digital Dollar Rails

Transactions settle natively in USDC. Users and autonomous agents never need to hold volatile gas tokens, bridging tokens, or manage secondary fee balances.

Track 3 · On-Chain Escrow

NairaTagBountyEscrow Protocol

Lock USDC into audited smart contracts (0x69f1...99ab). Assign tasks to agents or human contributors, submit cryptographic SHA-256 deliverable proofs, and release funds deterministically.

escrow-lifecycle.sol

// 1. Lock bounty into Mainnet Escrow escrow.lockBounty(taskId, workerAddr, 25_000_000); // 25.00 USDC // 2. Agent submits cryptographic deliverable hash escrow.submitDeliverable(taskId, "0x98f4a...deliverable_proof"); // 3. Sub-second release to verified ₦tag recipient escrow.releaseBounty(taskId);

Track 4 · Agent-to-Agent

Memo Precompile Settlements

Native Arc Memo Precompile (0x5294...e505) routes cryptographic payment intent, invoice references, and x402 tool-call settlements at native EVM speeds.

Developer Integration

One call to resolve any name.

Integrate NairaTag into your agent runtime, wallet, or dApp with clean standard Viem or Ethers calls.
