Transaction

Internal TransfersEvery call in this transaction that moved native ETH — the transaction's own top-level call included, which is why a plain ETH transfer shows 1 and a contract call that moves only tokens shows 0. Same convention as the Internal tab on an address.

1

SSTOREsHow many SSTORE opcodes this transaction executed — every write to contract storage, including repeated writes to the same slot. The costliest thing a transaction does to the chain's state. 0 on a reverted tx — no state was committed.

4

Slots WrittenHow many distinct storage slots were written (each slot counted once, however many times it was rewritten). Lower than SSTOREs means some slots were written repeatedly.

4

Contracts TouchedHow many distinct contracts had their storage written by this transaction. A simple token transfer touches one; a DeFi route touches every pool and vault along the path.
