What happened?
1inch integrated its Swap API into the Coinbase app, letting Coinbase users access DEX aggregator services directly. This integration enables non-custodial token swaps through the app’s built-in self-custodial wallet. It’s 1inch’s biggest U.S. client win and a major expansion of Coinbase’s on-chain trading features.
Who does this affect?
Coinbase’s 100-million-plus user base now has easier access to DeFi-style swaps without leaving the app. 1inch gains massive new retail liquidity and validates its “1inch Business” push to serve institutions and centralized platforms. Traders, builders, and rival exchanges and aggregators will notice as on-chain trading becomes more mainstream.
Why does this matter?
The move can drive more retail capital onto on-chain markets, boosting DeFi liquidity and tightening swap spreads. It raises expectations for DEX infrastructure and pressures other platforms to add similar non-custodial features, speeding institutional and mainstream adoption. Overall, expect higher decentralized trading volumes, lower costs for swaps, and increased competition between centralized and decentralized trading venues.
