A library you can use to parse the Jupiter v6 swap instruction. It is also the same library that we use to parse the swap information on the https://station.jup.ag/stats page.

After cloning the repo, in the project directory run yarn install. Then:

yarn start lookup-tx --signature <TRANSACTION_SIGNATURE> --rpc <RPC_URL>

For an example on how to use the library, you can check out: src/cli.ts.

If you are using this via NPM, make sure that you are using the right version for the right contract:

• JUP4Fb2cqiRUcaTHdrPC8h2gNsA2ETXiPDD33WcGuJB: 1.0.5
• JUP5pEAZeHdHrLxh5UCwAbpjGwYKKoquCpda2hfP4u8: 5.0.1
• JUP5cHjnnCx2DppVsufsLrXs8EBZeEZzGtEK9Gdz6ow: 5.2.0
• JUP6LkbZbjS1jKKwapdHNy74zcZ3tLUZoi5QNyVTaV4: 6.0.7

If you will need all of them in order to parse different contract, you can include them in your package.json as this:

{
  "dependencies": {
    "@jup-ag/instruction-parser-v4": "npm:@jup-ag/[email protected]",
    "@jup-ag/instruction-parser-v5": "npm:@jup-ag/[email protected]",
    "@jup-ag/instruction-parser-v5-1": "npm:@jup-ag/[email protected]",
    "@jup-ag/instruction-parser-v6": "npm:@jup-ag/[email protected]"
  }
}

For the old V4 contract, check out v4 tag.

For the old V3 contract, check out v3 tag.
