Module transaction_cost 

Opt-in transaction fee, compute-budget, and relay-tip parsing.

These functions are intentionally separate from DEX event parsing. Callers that do not request transaction costs incur no instruction scan.

Functions

parse_rpc_transaction_cost

Parses costs from a base64-encoded RPC transaction response.

parse_shred_transaction_cost

Parses requested compute budget and outer relay tips from a ShredStream transaction. Transaction status metadata and ALT-loaded addresses are not present in shred entries, so fee and consumed-CU fields remain None and tips whose recipient is ALT-loaded cannot be recognized.

parse_yellowstone_transaction_cost

Parses costs from a Yellowstone transaction, including ALT-loaded accounts and inner System Program transfers. Returns None when the transaction message is absent.
