[SOL Chain] Decrypt ProgramData Base64-58 for pumpfun and co

Hello,

My question is a bit specific : I'm gathering data with logsubscribe (web sockets) within the SOL chain but the info included in the ProgramData is very parse. I'm trying to find a way to decrypt it. I know it's Base64-Base58 but I didn't find a documentation for a specific scheme.
If I can't do that, I'll have to run a gettransaction after that and I'll lose precious hundred ms (aaaand my parsing isn't 100% accurate for now).

Any bit of info to share on this ?

(Purpose is of course to "listen" to specific wallets to run a copy trading bot. Time and precision is the essence. And good wallets. Last part is harsch).

Thanks in advance

Best regards,

Daima

The ProgramData you're getting via WebSockets is likely Base58-encoded, especially given that Solana uses Base58 encoding for addresses and public keys
Optimize WebSocket Subscriptions:. Ensure you're subscribing only to the events and addresses you're interested in, to minimize the volume of data you need to process.
Multi-threading. If you're handling a lot of data, use multi-threading or multi-processing in Python or JavaScript

Hello,
I have no problem about the number of events or the processing power : I'm only testing for now so it's okay.
However, it seems that the encoding isn't "the same" each time ? Between Meteora, Raydium and Pumpfun (and even between the different Pumpfun address).
Is it intended ?
Is it documented somewhere ?

You’re right Solana logSubscribe returns logs with limited decoding; to parse ProgramData, you typically need the target program’s ABI or instruction layout which most programs don’t expose. Without that, logs won’t decode cleanly.

That's what I thought
Thanks for confirming this point.
So I'm stuck with a gettransaction following the logSubscribe parsing.

It's sad
