Get all transactions for an NFT on Solana

You can use the getSignaturesForAddress RPC method on the mint address and walk backward to get all the transactions.

Here is an example in JS:

import {
  Connection,
  clusterApiUrl,
  ConfirmedSignatureInfo,
  PublicKey,
} from "@solana/web3.js";

const connection = new Connection(clusterApiUrl("mainnet-beta"));

export const getTxs = async (connection: Connection, pubkey: PublicKey) => {
  const txs: ConfirmedSignatureInfo[] = [];

  // Walk backward
  let lastTransactions = await connection.getConfirmedSignaturesForAddress2(
    pubkey
  );
  let before = lastTransactions[lastTransactions.length - 1].signature;
  txs.push(...lastTransactions);

  while (true) {
    const newTransactions = await connection.getConfirmedSignaturesForAddress2(
      pubkey,
      {
        before,
      }
    );
    if (newTransactions.length === 0) break;
    txs.push(...newTransactions);
    before = newTransactions[newTransactions.length - 1].signature;
  }

  return txs;
};

getTxs(
  connection,
  new PublicKey("2Nzt8TYeAfgJDftKzkb7rgYShVvyXTR7cPVvpqaZ2a4V")
);

The equivalent method in Solana.py is this one https://michaelhly.github.io/solana-py/rpc/api/#solana.rpc.api.Client.get_signatures_for_address
