Verifiable payments for AI agents, now going multi-rail.
BSVKey settles agent payments per call, non-custodially, and returns a receipt anyone can verify. That model is rail-neutral. It is live on BSV, and the XRP Ledger rail now settles and verifies end to end on mainnet.
The rails
The settlement layer is a rail. The verifiable-receipt layer on top of it is not, it is the same across every rail. We add rails where agents already hold value.
BSV Live
Pay-per-token inference and a drop-in x402 API paywall. On-chain, non-custodial settlement with a verifiable receipt per call. In production today.
XRP Ledger Proven on mainnet
The same pay-per-call model settled on the XRP Ledger, for agents and services that already transact in XRP. The rail is built and open-source: the full pay, verify, sign, and verify-claim loop has run against a real settlement on XRP mainnet. A hosted product follows; early-access partners shape it.
More rails As demand warrants
Rails are added where there is real agent volume, not for a logo grid. Tell us the rail you need and why.
What stays the same on every rail
Switching the settlement rail does not change the guarantee. The part that matters is rail-neutral by design.
Non-custodial
Funds settle straight to the payee. BSVKey never holds them, on any rail.
Pay per call
Metered settlement per request, no accounts or prepaid lock-in required.
Verifiable receipts
A content-addressed, signed record of each settled call that anyone can verify offline, tied to the on-chain transaction. The claim format is shared across rails; only the signature envelope and address encoding are rail-specific.
We build the verifiable-receipt layer in the open. We contributed the BSV rail to an emerging post-call attestation standard for agent payments: EmbryoSpace/bsv-capacity-attest. The XRP rail follows the same content-addressed core and is open-source too: EmbryoSpace/xrp-capacity-attest.
Building on XRP, or want it?
Early-access partners tell us what they would settle on the XRP rail (inference, an API paywall, or something else) and roughly what volume. That is what decides build order.
