attest.tollkit.dev/attest
Prove what a web page said: signed, timestamped evidence of a page's content, with a screenshot. Returns the rendered text and its SHA-256 hash, a screenshot and its hash, response headers, the serving IP and TLS certificate, all signed so anyone can verify it later without trusting us. Use for web evidence, archiving terms of service or prices, compliance records, citation checks and disputes. $0.25 per page; verification is free.

On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-09-28; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 2 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
