[SOLVED] How can I retrieve market ids for Solana token swap program?

How can I retrieve market ids for Solana token swap program?

Having mint addresses of two spl tokens on Solana mainnet, I need to find public key of all possible markets (i.e. marketId in the following code snippet) available on Solana to get token swap info from:

const tokenSwap = await TokenSwap.loadTokenSwap(
    con,
    new PublicKey(marketId),// << HERE
    TOKEN_SWAP_PROGRAM_ID,
    payerAaccount
);

I could not find any repository (similar to Raydium or Serum lp addresses) on github or anywhere else. Where can I find a list of liquid markets for spl token swap program? and/or is there any other way to calculate or retrieve token swap info based on token mint addresses?

Solution

To get the addresses of markets for two mint addresses, you'll need to go through a few steps.

Get all of the program accounts for the token swap program: https://docs.solana.com/developing/clients/jsonrpc-api#getprogramaccounts
Deserialize each of those as a TokenSwap type by decoding, e.g. https://github.com/solana-labs/solana-program-library/blob/07bf49fdb820f8e3a40550998723e4878506af0b/token-swap/js/src/index.ts#L258
Check that the mintA and mintB are the ones expected: https://github.com/solana-labs/solana-program-library/blob/07bf49fdb820f8e3a40550998723e4878506af0b/token-swap/js/src/index.ts#L65

Note, however, that the current TOKEN_SWAP_PROGRAM_ID is deprecated by Serum in favor of using the Serum orderbooks. You may have to use their SDKs for Serum, or Raydium's to interact with those programs.
