@piprail/sdk v2.16.1 — GoPlausible settles Solana, live-proven

npm install @piprail/sdk@2.16.1

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.

Live-proven on mainnet, three times

A real 402 → pay → verify → 200 round trip on the exact rail, run three times with three
different transactions. Every run:

• the merchant received exactly 0.01 USDC
• the buyer paid 0 SOL
• GoPlausible's sponsor 8a8fFNfk…RAYi paid the 10001-lamport fee, read off accountKeys[0] of
  the settled transaction. That is what proves the rail was sponsored rather than self-paid.
• a replay of the same proof was rejected

The full hash is recorded in the registry note, so verify-tx.mjs re-checks it on-chain: 26
verified, 0 refuted across every facilitator we ship.

Also in this release

The seed is locked by a test that fails if it is dropped, and that asserts Solana keeps more than
one keyless option so the chain can never silently narrow to a single vendor.
