subfloor_refusals

Fills that a recipient-keyed price floor turned away, on Base Sepolia.

The floor is checked inside swap() on a forked 1inch SwapVM router, between taker validation and the transfers. When a fill would settle below it, the transaction reverts with SettledBelowFloor(recipient, tokenIn, tokenOut, executionRate, floorRate).

A revert emits no logs. That is why this module exists rather than a subgraph handler: nothing log-driven can observe a refused fill. The Firehose block model carries every transaction with its status and its full call tree, so the revert payload can be read and decoded there.

The module walks the call tree rather than only the outermost frame, because a revert can come from a nested call and taking only the top level loses refusals routed through an aggregator. It decodes only the SettledBelowFloor selector — most reverts are ordinary failures and counting those would inflate the one number that has to be exact.

Rates are emitted as decimal strings in the canonical convention, received * 1e18 / given. They routinely exceed u128 and cannot be narrowed without corrupting the reported number.
