DEX Integration

Overview​

Jupiter is one of the most widely integrated protocols, so a lot of work is involved in minimizing issues on new integrations and making each integration valuable to our users and partners.

Our top priority is securing the best prices and the best token selection for our users, so we will focus on DEXes that will bring the most benefits to them.

We do not charge fees for integration.

Integration Prerequisites​

Minimum DEX TVL​

Given the amount of integration work involved:

  • A DEX must have enough liquidity to be useful for trading and to attract volume, as of 1 January 2025, minimum DEX TVL is $500,000.
  • Each market/pool must have a minimum liquidity to show up on Jupiter, as of 1 January 2025, minimum market liquidity is $500.

Markets API​

  • This API should track all markets/pools that is listed or delisted, this will allow us to automatically track new markets as you add them to your DEX.

Rust SDK​

Security Audit​

AMM Interface​

To facilitate integration of your DEX into the Jupiter Core Engine:

  • Provide a DEX SDK that works with the Jupiter AMM Interface.
  • Enable us to fork your SDK, this ensures our users that we can guarantee maintenance, support for the SDK, and fix potential bugs related to integrated DEXs.
note

get_accounts_to_update provides the necessary accounts to fetch, they are batched and cached by the Jupiter Core Engine and delivered through update to the AMM instance, there might be multiple calls to quote using the same cache so we do not allow any network calls in the entire implementation.

Resource and Support

You can refer to the implementation guide https://github.com/jup-ag/rust-amm-implementation for easier integration with Jupiter.
