Internal TransfersNested calls in this transaction that moved native ETH. The transaction's own top-level call is NOT counted — its value is the transaction's own, shown above — so a plain ETH transfer shows 0, and so does a contract call that moves only tokens. Same convention as the Internal tab on an address.

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.
19
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.
12
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.
