voteoptional bool

true = only vote txns, false = exclude votes, null = all. Set false for most app use cases.

failedoptional bool

true = only failed, false = only successful, null = all

signatureoptional string

Filter for a specific transaction signature. Useful for tracking confirmation stages.

account_includerepeated string

Match transactions involving ANY of these accounts

account_excluderepeated string

Exclude transactions involving ANY of these accounts

account_requiredrepeated string

Match only if ALL of these accounts are present in the transaction

            vote: Some(false),          // Exclude vote transactions
