请求参数

• <array> - An array of transaction signatures to confirm, as base-58 encoded strings
• <object> - (optional) Configuration object containing the following field:
  • searchTransactionHistory: <bool> - if true, a Solana node will search its ledger cache for any signatures not found in the recent status cache

响应结果

getSignatureStatuses方法返回一个RpcResponse对象，其中包含一个TransactionStatus对象数组， 每个对象的值可能是：

• <null> - 未知的交易
• <object>
  • slot: <u64> - The slot the transaction was processed
  • confirmations: <usize | null> - Number of blocks since signature confirmation, null if rooted, as well as finalized by a supermajority of the cluster
  • err: <object | null> - Error if transaction failed, null if transaction succeeded. TransactionError definitions
  • confirmationStatus: <string | null> - The transaction's cluster confirmation status; either processed, confirmed, or finalized. See Commitment for more on optimistic confirmation.
