DeFi Swaps Simplified

Driving Your Strategic Advantage

Intent Based

Intent Based

Users choose what they want to swap, and Changelly DeFi handles the rest. Our resolver model finds the best price and executes swaps automatically, removing route comparisons, bridging delays, and other DeFi friction. You get better rates, zero complexity, fast settlement, and higher completion.
User Centric

User Centric

  • Changelly DeFi API supports over 1.5 billion assets. Users submit a swap intent, sign once, and the swap completes.
  • On Solana and Bitcoin, the experience is fully gasless.
  • On Ethereum and Tron, users only need a one-time setup.
Security First

Security First

  • Users never hand over funds to a centralized entity. Assets are locked in on-chain escrow and released only when smart-contract conditions are met.
  • Changelly DeFi has no custody or KYC. Every settlement is verifiable on-chain.
Fully Decentralized

Fully Decentralized

Changelly DeFi API is an open, permissionless protocol. Resolvers compete to fill swap intents, smart contracts enforce every settlement, and all execution is transparent and verifiable on-chain.
