Yieldex invites partners for cross-chain smart-wallet infrastructure on Internet Computer

Yieldex has begun sharing details of a new non-custodial smart-wallet infrastructure built on the Internet Computer using ChainFusion. The project aims to make managing assets across different blockchains such as Ethereum, Bitcoin and Solana easier and more automated for users.

Built under a third-stage US$25,000 developer grant, Yieldex’s architecture allows users to connect via a single EVM wallet or Principal ID and generate addresses on multiple chains automatically. The system also supports session-key automation, enabling functions such as yield optimisation, portfolio management and cross-chain swaps.

ChainFusion provides a secure framework that lets Internet Computer canisters manage wallets across multiple chains, sign transactions and support composable futures like on-chain scheduling or DAO treasury management. The infrastructure remains fully non-custodial, meaning users keep control of their assets. Automations are handled through session keys with custom-defined policies, and all code is open-source from the outset.

The team is looking to connect with projects working on wallet management, cross-chain tooling or automation agents on ICP, as well as DeFi protocols or DAOs that could integrate yield and smart-wallet features. They are also inviting ideas from developers exploring multi-chain automation.

Key milestones under the grant include wallet generation and EVM integration, protocol whitelisting and transaction execution, followed by automated rebalancing and deployment to mainnet.

ChainFusion itself is part of the Internet Computer’s wider toolkit, allowing canisters to interact with other blockchains without relying on bridges, using threshold signing, HTTPS outcalls and direct or RPC integrations. It supports Bitcoin natively, EVM chains and now Solana, among others.

Yieldex is positioning this project as a building block for multichain DeFi infrastructure, enabling non-custodial wallets to manage assets and interactions across chains by using the Internet Computer’s compute and automation capabilities. The team is openly inviting feedback and collaboration as development continues.
