Coinbase has introduced a tool in its Coinbase Developer Platform (CDP) designed to let developers integrate self-custodial wallets into their apps without any hiccups. The Embedded Wallets software developer kit (SDK) includes built-in features like crypto onramps, token swaps and a 4.1% annual return on USDC balances, aiming to eliminate the tradeoff between user experience and custody risk. Unlike traditional wallet integrations that require browser extensions or seed phrases, CDP Embedded Wallets enables onboarding through email, SMS or OAuth. Users will be able to begin transacting right away, while developers retain full control over the front-end experience, without touching custody or managing complex compliance requirements. Coinbase said the SDK will be the “everything wallet” for Web3 builders, offering a good user experience with enterprise-grade infrastructure. It runs on the same systems that power Coinbase DEX, offering secured key management, recovery services and future support for smart contract accounts. With use cases spanning decentralized finance (DeFi), gaming, fintech and creator platforms, the Embedded Wallets SDK reflects a growing demand for crypto to become more accessible.
