About
Interoperability is the future of DeFi.
When users can move seamlessly between chains; when every trade can access all liquidity; when dApps, wallets and protocols work together by default, and every transaction can take place onchain - that’s when the real potential of decentralized finance will come alive.
Unite DeFi is your call to make this happen.
Join 1inch and the largest Ethereum developer community to tackle the challenges that will define the next evolution in Web3. Connect networks; bring operations on chain; even create your own dApp. Whatever project you choose, you’ll build alongside the 1inch team, with their cutting-edge tech stack, and finish by presenting your work to some of the most respected minds in the industry—and all for your share of bounties worth $525,000.
And as for the future? Anything’s possible. Just ask 1inch: their aggregator was born at an ETHGlobal hackathon.

1inch is a unified DeFi ecosystem, built around the DEX aggregator with the best swap rates. Swap, hold & track digital assets - and ship scalable, secure applications with the complete Web3 stack. 1inch protocols give you access to hundreds of liquidity sources across 12+ chains, including Solana, for secure trading at the best rates. Builders can unlock them all with 1inch Developer Portal: 17 APIs that bring you the technologies you need to scale. The 1inch Swap API gives you optimized routes with the new Pathfinder algorithm; Fusion and Fusion+ are the building blocks of intent-based and cross-chain swaps, with MEV protection and zero gas fees as standard. The rest offer everything from spot price and node access to limit orders and dynamic gas pricing. With complete usage statistics and API management, custom plan configuration, and a one-click Swagger UI - 1inch APIs and the Developer Portal give you the tools you need to build your project.
