Transferring OCP tokens

[nealburton]

I'm trying to follow the tutorial here to transfer an OCP token: https://magiceden-oss.github.io/open_creator_protocol/open-creator-protocol/tutorials

I have some questions

1. How do I know if a given token address is an OCP token?
2. How do I know which is the correct Policy account to use in the transfer instruction?

1. https://magiceden-oss.github.io/open_creator_protocol/open-creator-protocol/concepts#mint-state One can use the mint_state to determine if a token is under the control of OCP
2. the policy is a field inside mint_state, see the code example below

export const findMintStatePk = (mint: PublicKey) => {
  return PublicKey.findProgramAddressSync(
    [utils.bytes.utf8.encode("mint_state"), mint.toBuffer()],
    PROGRAM_ID
  )[0];
};

const mintStatePk = findMintStatePk(mint);
const mintStateAcc = await conn.getAccountInfo(mintStatePk);
const policy = mintStateAcc.policy
