agent payments need receipts that hold up.

agents are starting to check out, book, and pay. when the customer says “i never told the agent to buy that,” proof settles it.

the shift

google’s agent payments protocol (ap2) and the x402 standards work are making agent transactions real, and payment rails are racing to support them.

those protocols prove intent at the moment of checkout. they do not answer the question that comes after: the customer disputes the charge, and nobody has court-admissible proof of what the agent was cleared to do and what it actually did.

how syen closes it
  1. 01seal

    the job and the agent's authority are locked into a signed record before it acts.

  2. 02anchor

    every action after that is chained to it and anchored daily to a trusted timestamp.

  3. 03settle

    when a dispute lands, you pull one proof and settle it in seconds.

who this is for
payment rails

enable agent-initiated checkout with proof behind every transaction.

merchants

accept agent transactions without absorbing a new class of dispute.

agent platforms

show what your agents were cleared to spend, and what they spent.

why now

the first rail with provable agent checkout wins.

disputes follow volume. the rail, merchant, or platform that can prove authorization wins the disputes and the regulator conversation.
