I need to find out who currently owns a particular Solana NFT and also get a history of previous owners using Python.
Right now my approach involves using get_confirmed_signature_for_address2 to fetch token signatures first. After that I grab the transaction data from the most recent signature. Finally I pull out the owner info with this code:
current_owner = tx_data["result"]["meta"]["postTokenBalances"][0]["owner"]
This method works but feels overly complicated. Is there a more direct approach to get both current and historical ownership data for Solana NFTs? Maybe there’s a simpler API call or library function I’m missing?
Interesting question! I’ve been dealing with similar stuff recently. Have you tried the solana web3.js python equivalent or anchorpy? They’ve got built-in methods for NFT metadata retrieval that could simplify this.
Also - are you targeting a specific collection or random tokens? Some collections have their own APIs with ownership data. Magic Eden and OpenSea often have endpoints that beat raw RPC calls.
For historical data, parsing all those transaction signatures might not be your only option. Services like Helius or QuickNode offer enhanced APIs that already aggregate ownership history. Worth checking if you’re doing this at scale.
What’s your dataset size? If it’s just a few tokens, your current approach works fine. But for bulk analysis, there are better ways to batch these requests.
yeah, dats way too complicated. just use getTokenAccountsByOwner rpc - much cleaner for checking current ownership. you’ll still have to parse transactions for history tho. check out metaplex’s helper functions, they might save u some headaches.
Use getTokenLargestAccounts instead - it’ll give you current ownership directly without parsing transaction data. Way cleaner than what you’re doing now.
For tracking history, I’ve had better luck monitoring program logs with getProgramAccounts using the Token Program ID. Filter by mint address and you can track balance changes over time.
Heads up though - some NFTs transfer through program instructions that won’t show in standard token balance changes. Cross-program invocations make ownership trails messy. Found this out the hard way tracking gaming NFTs that moved through escrow contracts.
Solders library has solid abstractions for these RPC calls if you want to stick with pure Python instead of mixing in JavaScript.
