Crypto Earn
Multi-chain USDT earn-product UI — a DeFi delivery sample, not a public yield product.
Crypto Earn is a DApp sample for yield-style products: lock / flexible tiers, multi-chain wallets, and a daily settlement interface. It shows how to ship a DeFi earn front-end and contracts. APY numbers in the UI are demo parameters, not a live investment offer.

- 15+ chains — Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Avalanche, Solana, zkSync Era and more
- Daily settlement UI — 24-hour settlement flow in the interface
