Protocol Integration

Integration Process

To integrate with Tycho, you need to provide 3 components:

1. Indexing: Provide access to the protocol state that the simulation needs.

2. Simulation: Provides simulations of the protocols logic.

3. Execution: Define how to encode and execute swaps against your protocol.

Indexing

Provide a substreams package that emits a specified set of messages. If your protocol already has a substreams package, you can adjust it to emit the required messages.

Simulation

Tycho currently exposes two integration modes to specify the protocols' underlying logic:

• VM Integration: This integration type requires implementing an adapter interface in any language that compiles to the respective VM byte code. This SDK provides the interface only in Solidity. Read more here.

• Native Rust Integration: Implement a Rust trait that describes the protocol logic.

Execution

To enable solvers to execute swaps over your protocol, you need to implement two components:

1. SwapEncoder: A Rust struct that formats input/output tokens, pool addresses, and other parameters correctly for the Executor contract.

2. Executor: A Solidity contract that handles the execution of swaps over your protocol's liquidity pools.
