High performance intent-based trading program on Solana

Thank to the power of Solana and Pinocchio, we create a program that enables decentralized intent-based trading on the Solana blockchain.

Design

1. Stateless order

• Orders are represented as intents without storing state on-chain.
• This reduces on-chain storage costs and increases scalability.

2. Dutch auction mechanism

• Orders are fulfilled using a Dutch auction mechanism.
• This allows for dynamic pricing based on market demand.
• Solvers can compete to fulfill orders at the best price and timing.

3. Decentralized fulfillment

• Any participant can act as a solver to fulfill orders.
• This promotes decentralization and reduces reliance on centralized entities.
• Order will be published on-chain, and solvers can monitor and fulfill them.

Build and test

1. Build

Entrypoint

1. Initialize order

• Create a new intent-based order

2. Cancel order

• Cancel an existing order

3. Fulfill order
