    Orca Typescript SDK

    The Orca SDK contains a set of simple to use APIs to allow developers to integrate with the Orca exchange platform.

    Learn more Orca here.

    Trading Orca Liquidity Pools

    • Get detailed quotes and make swaps between trading pairs in an Orca Pool
    • Check your Orca Pool LP token balance and total supply

    Supported Orca Pools

    • The SDK supports all pools currently listed on Orca

    Provide Liquidity to Orca Pools

    • Deposit liquidity to supported Orca Pools
      • Deposit a trading pair, and receive LP token
    • Withdraw liquidity from supported Orca Pools
      • Withdraw a trading pair in exchange for LP token

    Aquafarm Support

    • After depositing liquidtiy to a pool, the LP token can be deposited into the corresponding farm to receive an equivalent amount of farm token
    • Remember to withdraw the LP token in exchange for farm token before withdrawing liquidity from Orca Pool

    DoubleDip Support

    • For farms with double-dip, the aquafarm tokens can be deposited into double-dip farm to receive double-dip rewards

    Features Coming Soon

    • More trader information (APY, Volume)

    Devnet Testing

    The example code above can be run on devnet by updating the import statement:

    import { getOrca, OrcaFarmConfig, OrcaPoolConfig, Network } from "@orca-so/sdk";

    And changing two lines of code like so:

    const connection = new Connection("https://api.devnet.solana.com", "singleGossip");
    const orca = getOrca(connection, Network.DEVNET);

    One caveat to note is that there are only a few devnet pools available, so if you try to access pools that are only available on mainnet, the code will throw an error. The example code uses ORCA_SOL, which exists on the devnet.

    Technical Notes

    Decimals & OrcaU64

    The SDK relies on the use of Decimal for number inputs and Decimal/OrcaU64 for token-value inputs. If a Decimal instance is provided for a token-value input, it will be automatically transformed to the token's scale.

    Stability of the Public Util Functions

    We hope you find the tools we used to build our API useful in the public/utils folder. Due to our on-going development of the Orca platform, we cannot guarrantee the stability of the util APIs. The trading APIs can only be upgraded on major version updates.
