Features

• ENS-standard resolution — Text Records (EIP-634), Contenthash (EIP-1577), multi-coin addresses (ENSIP-9/SLIP-44), reverse resolution.
• Duration-tier NFT cards — fully on-chain SVG. Card color reflects committed duration (charcoal → gold), ratchets up on renewal, never down with time, red when expired.
• Localized profiles — 12 languages with per-field English fallback.
• AI-agent payment routing — bridges .dex names to ERC-8004 identity and x402 payment endpoints.
• Subname commerce — owners sell subnames with token/SBT access gating.
• Trading — fixed-price marketplace plus English (ascending, escrow + anti-snipe) and Dutch (descending) auctions, paid in USDC/USDT, with on-chain LISTED/AUCTION marks.
• Permissionless auto-renewal — pre-approve a stablecoin; anyone can trigger renewal, with on-chain time-window and price-cap re-validation.
• Polygon-native — low gas, native USDC/USDT payment.
• Discounts — ERC-20 holding / SBT / staking (non-stacking, max 50%).

▶ 한국어로 보기

• ENS 표준 해석 — 텍스트 레코드(EIP-634), 콘텐츠 해시(EIP-1577), 다중 코인 주소(ENSIP-9/SLIP-44), 역방향 해석.
• 만료 등급형 NFT 카드 — 완전 온체인 SVG. 카드 색이 약속한 보유 기간을 반영(charcoal→gold), 갱신 시 상승, 시간 경과로 불변, 만료 시 빨강.
• 다국어 프로필 — 12개 언어, 필드별 영어 폴백.
• AI 에이전트 결제 라우팅 — .dex 이름을 ERC-8004 신원·x402 결제처에 연결.
• 서브네임 커머스 — 소유자가 토큰/SBT 게이팅으로 서브네임 판매.
• 거래 — 고정가 마켓플레이스 + 영국식(상승, 에스크로·스나이핑 방지)·네덜란드식(하락) 경매. USDC/USDT 결제, 온체인 LISTED/AUCTION 마크.
• 무허가 자동 갱신 — 스테이블코인 사전 승인 후 누구나 갱신 트리거, 온체인 시점·가격상한 재검증.
• Polygon 네이티브 — 저가스, USDC/USDT 네이티브 결제.
• 할인 — ERC-20 보유/SBT/스테이킹 (비중첩, 최대 50%).

Quick Start

npm install
npx hardhat compile
npm test                 # 218 tests

Deploy:

npx hardhat ignition deploy ignition/modules/DXDeployLocal.ts    # local
npx hardhat ignition deploy ignition/modules/DXDeployAmoy.ts --network amoy
npx hardhat ignition deploy ignition/modules/DXDeployPolygon.ts --network polygon

The mainnet contracts above were deployed deterministically via CreateX (not the Ignition modules) so that every contract carries a 0xdeed… vanity address and an explicit owner. The Ignition modules remain the supported path for local and Amoy deployments. See DEPLOYMENT.md for the mainnet deployment details.

Integration

Resolve a name (read-only):

node = namehash("alice.dex")
DXResolver.addr(node, 60)        // ETH/EVM address
DXResolver.text(node, "avatar")  // text record
DXRegistrar.tokenURI(tokenId)    // on-chain NFT card

Register (commit-reveal):

1. commitment = keccak256(label, owner, duration, resolver, paymentToken, secret)
2. controller.commit(commitment)
3. wait minCommitmentAge
4. controller.register(label, owner, duration, resolver, secret) { value: rentPrice }
5. resolver.setAddr(node, 60, owner)   // recommended UX

The test/ directory contains working examples for every function — read the relevant test before integrating.

test/ 디렉토리에 모든 함수의 동작 예제가 있습니다. 연동 전 해당 테스트를 먼저 읽으세요.

이름 해석(읽기 전용), 등록(커밋-리빌) 흐름은 위 영문 코드 블록을 참조하세요. 등록 후 setAddr를 호출해야 주소가 해석됩니다(ENS 표준).

Architecture

User → Controller (register/pay/discount) → Registrar (mint NFT) → Registry (authority)
                                                  ↓
                                             Resolver (name → data)
       Controller → PriceOracle (USD→POL, Chainlink)

Trading:  Marketplace / EnglishAuction / DutchAuction → Registrar (NFT transfer + SVG mark)
          fees → RevenueDistributor.  SubscriptionRenewer → Controller.renew
