Uniswap V3 SDK Rust

A Rust SDK for building applications on top of Uniswap V3. Migration from the TypeScript Uniswap/v3-sdk.

It is feature-complete with unit tests matching the TypeScript SDK. But error handling is not as graceful as one may expect. The error handling is still a work in progress.

Features

• Opinionated Rust implementation of the Uniswap V3 SDK with a focus on readability and performance

• Usage of alloy-rs types

• Reimplementation of the math libraries in Uniswap V3 Math In Rust based on optimizations presented in Uni V3 Lib

• Extensive unit tests and benchmarks

• An extensions feature for additional functionalities related to Uniswap V3, including:

  • pool module for creating a Pool struct from a pool key and fetching the liquidity map within a tick range for the specified pool, using RPC client
  • position module for creating a Position struct from a token id and fetching the state and pool for all positions of the specified owner, using RPC client, etc
  • price_tick_conversions module for converting between prices and ticks
  • ephemeral_tick_data_provider module for fetching ticks using an ephemeral contract in a single eth_call

Getting started

Add the following to your Cargo.toml file:

uniswap-v3-sdk = { version = "0.25.0", features = ["extensions"] }

Usage

The package structure follows that of the TypeScript SDK, but with snake_case instead of camelCase.

For easy import, use the prelude:

use uniswap_v3_sdk::prelude::*;

Contributing

Contributions are welcome. Please open an issue if you have any questions or suggestions.

Testing

Tests are run with cargo test. To test a specific module, use cargo test --test <module_name>.

Linting

Linting is done with clippy and rustfmt. To run the linter, use:

cargo clippy --all-targets --all-features -- -D warnings
cargo fmt --all -- --check

Benchmarking

Benchmarking is done with criterion. To run the benchmarks, use cargo bench.
