Prize details
Runners up for the decentralized solver prize Build a decentralized solver that integrates with 1inch Fusion+ for cross-chain swaps using NEAR's Shade Agent Framework and Trusted Execution Environment. --- There is an existing decentralized NEAR Intents solver here: Solver manager and deployer https://github.com/Near-One/tee-solver/ Solver https://github.com/think-in-universe/near-intents-tee-amm-solver/tree/feat/tee-solver --- It listens for intents, generates quotes, and submits them for execution on NEAR Intents. Your task is to build a similar system that works with 1inch Fusion+ and its meta-order format. Make sure the solver is created using NEAR’s Shade Agent Framework and is deployed in a Trusted Execution Environment. --- The Shade Agent Framework allows you to build decentralized solvers, enabling users to delegate and provide liquidity to solvers without requiring trust that the solver will behave correctly or having to set up their own solver.
Qualifications
Your solver must listen for quote requests (mocked or real), produce valid 1inch Fusion meta-orders using NEAR's Chain Signatures, include comprehensive documentation with setup instructions, and demonstrate end-to-end functionality. Bonus points for modular architecture that extends to other protocols.
