Caffeine prepares to unlock full Web3 functionality with multi-chain support

Caffeine, the AI-powered app builder on the Internet Computer, is moving towards full Web3 integration, enabling users to create onchain, multi-chain decentralised applications capable of handling and securing digital assets like Bitcoin, Ethereum, Solana and ICP.

According to DFINITY founder Dominic Williams, the platform will soon introduce a “Web3 App Mode” that lets users maintain permanent ownership of their draft canisters — the smart contracts that power Caffeine’s applications. At present, Caffeine recycles unused draft canisters to conserve computational resources, a design choice that makes sense for efficiency but prevents those canisters from safely holding tokens. The new mode will allow developers to build applications that securely process and custody assets without losing control over them during the development cycle.

The update will also train Caffeine’s AI on robust token management and multi-chain design patterns, so it can generate and maintain DeFi-ready code automatically. Williams said the team plans to integrate the latest features of the Motoko programming language, including “mix-ins” that let the AI draw from a library of proven DeFi components rather than coding everything from scratch. This not only increases reliability but also keeps Caffeine-generated applications aligned with Internet Computer’s safety rails, ensuring that apps retain their token references even after upgrades.

Once complete, the upgrade will allow developers to use Caffeine as a low-code gateway to multi-chain dApp creation — where an app could, for instance, interact with Ethereum smart contracts or manage Bitcoin custody while running fully onchain on the Internet Computer.

The work is still underway, with Caffeine targeting early next year for the rollout of its Web3 capabilities. If successful, it could make cross-chain development far more accessible by combining automation, AI guidance and decentralised infrastructure — a combination that aligns well with Web3’s growing demand for interoperability without centralised intermediaries.
