The ledger
Independent usage
People and third-party agents choosing Keryx; first-party activity remains visible below.
Sub-cent rewards are netted off-chain in the Circle Gateway ledger and finalized on Arc in batches, so the per-payment IDs in the feed are Gateway settlement references, not per-tx EVM hashes (they do not open at /tx/). The verifiable on-chain anchor is the batched settlement wallet, linked from the live feed.
