npm install @piprail/[email protected] Every entry now carries a receipt you can actually open The facilitators page said 25 on-chain receipts against 29 entries. Three of the missing four kept only a truncated prefix (tx 4dL8jRKH…) and one recorded a verification with no hash at all. A prefix cannot be opened on an explorer and cannot be re-checked by our verifier, so those four were claims rather than proofs. Recovering the originals from chain history was tried first and failed, so each was re-proven with a fresh mainnet payment: PayAI and OpenFacilitator on Solana, PayAI and xp

npm install @piprail/[email protected] GoPlausible is now a keyless Solana facilitator GoPlausible told us they settle Solana as well as Algorand and Base, and asked to be listed. They were right, and this ships it with proof rather than trust. Solana previously seeded only PayAI and OpenFacilitator, so this is a third keyless option on that chain. No defaults change: the seed list is a convenience, and the SDK still depends on no facilitator.

npm install @piprail/[email protected] The XRP Ledger exact buyer 1,732 live rails, and as far as we can tell the only open-source buyer on that chain. The buyer signs a complete Payment and broadcasts nothing; the gate decodes the blob, re-derives every checked field from its own trusted accept, submits, and waits for a validated tesSUCCESS. XRPL is the family where the payer pays the fee, so there is no sponsor, no co-signature, and no fee-drain guard. The scheme replaces those with a list of MUST-NOTs the settler enforces: no Memos, no Paths, no tfPartialPayment, no Delegate, ne
