Everything a finance team asks for. None of the custody.

A receipt for every transaction

Payments in, refunds out, partials and duplicates. Each one has its own receipt that anyone can re-check against Arc.

Limits you set

Max per payment, a daily cap, a per-customer monthly cap and a second approval for large refunds. Anything outside is held for review.

History you can find

One searchable timeline of money in and out, with CSV export that carries the transaction and receipt link on every line.

New in Clearmark

Get paid faster, in more ways, and share it.

Settled Stamp

Every receipt shows how fast the money landed. Share the link and it unfurls as a branded card in WhatsApp, X or Slack. You choose whether amounts show.

Pay from any chain

Customers pay with USDC on eight other networks. Circle's bridge carries it to Arc, then it pays the invoice with its fingerprint, so it still matches automatically.
