Hi all, I want to integrate Pyth with a new chain, with smart contract support in Python. This is the flow of messages I gather should happen: Get the price info off-chain, using Hermes for example (curl "https://hermes.pyth.network/v2/updates/price/latest?ids[]=ec7a775f46379b5e943c3526b1c8d54cd…

Hi, Unfortunately we don’t have any documentation for the wire format. I recommend following the links below to get a better understanding: Pythnet SDK : This SDK has the wire formats for Pyth Update data. This test parses an actual update data. Hermes : This service constructs the Pyth update data…

@benji you are the best! Thanks for the detailed explanation.

Hey, following up here because I noticed some things were up with the analysis that Claude output. I’m still working on this to find a robust and complete solution. When I get there, I’ll be sure to share it here

Thanks @benji . Let me know if I can also help.

Code taken from the example explained above: Example VAA hex (first 100 bytes) vaa_hex = “504e41550100000003b801000000040d016ac12a9f…” sig_count = vaa_bytes[5] print(f"Signatures: {signature_count}") # 13 guardians signed If you look at the data closely, the 6th byte (index 5 for 0 based index…

Hi guys, deleted my earlier post as I wasn’t able to (or couldn’t figure out how to edit it) I went back to the drawing board, and put together this repository that shows & documents exactly how to extract and verify a wormhole VAA. One big gotcha I ran into, is that the Pyth VAA’s available from …

Dropping back in for a quick update. I haven’t been able to validate a Pyth Hermes v1 VAA, or find some cryptographic link between one and a Wormhole VAA with the same emitter address & sequence number from WormholeScan. Not really sure where to go from here. @ali perhaps you could shed some ligh…
