}Find Spending Transactions
Use nullifiers derived by your wallet to find the transactions that spent its inputs. Nullifiers select transactions. Each entry inresult.data holds every event of one selected Solana transaction, with its slot and signature.
Supply between 1 and 1,000 nullifiers. See pagination and freshness for page limits, continuation tokens, and incremental reads.
Request Parameters
object
Slot bounds. Resume a caught-up, uncapped read with
slot.gt set to the last page’s context.slot.object
Slot bounds for the read. Supplied bounds combine with AND.
number
Only include transactions after this slot.
number
Only include transactions at or after this slot.
number
Only include transactions before this slot.
number
Only include transactions at or before this slot.
number
default:"1000"
Maximum number of Solana transactions per page, from 1 to 1,000.
number
Minimum persisted indexer slot required for this read. Returns JSON-RPC error -32016 if the indexer is behind.
array
required
Base58-encoded 32-byte nullifiers to match against spent inputs.
string
Continuation token from the previous response. Pass it back unchanged with the same nullifiers and slot filters.
Authorizations
Your Helius API key.
Body
