Instance Method

transaction(at:)

Returns the transaction at the given index as an owned Transaction (safe to store past this block’s lifetime).

func transaction(at index: Int) -> Transaction

Parameters

index: Zero-based transaction index.

Discussion

Index 0 is always the coinbase transaction. Non-coinbase transactions follow in block order (typically ascending fee rate for miner-assembled blocks, but this is convention — the consensus rules don’t require it).

Precondition

index must be in 0..<transactionCount.
