In case you missed it this week, stables are evolving.

If you're taking notes at home, user experience and safety are the biggest takeaways from the @stripe x @phantom announcement.

If you've generated a picture with x402, we wanna talk.

🏔️ Agentic Commerce is finding a home on Solana 🏔️

Join us and the team over at @PayAINetwork on Friday at 11AM EST as we talk about the work to bring x402 to Solana, who's using it, and what builders are dreaming up.

Special guests from @SolanaFndn, @darkresearchai, and more.

14/ We’re open-source and collaborating. If you’re building smart-wallet or agent payments on Solana or EVM and want a clean x402 path, jump in: github.com/faremeter/f...

DM to co-design the EVM settlement scheme.

13/ TL;DR: Faremeter = x402 made practical - multi-chain, wallet-agnostic, plugin-extensible, and production-ready for agents & APIs. It keeps merchant middleware simple and pushes chain-specific complexity to the right place: the facilitator.

11/ Refunds & cancellations: these live at the scheme layer too (because each chain/wallet has different primitives). We’ve started exploration and will standardize patterns so merchants can adopt them with minimal friction.

10/ Dev ergonomics: Faremeter is plugin-first. Add a scheme for your chain/wallet, implement the client + facilitator interfaces, and you’re done. No forked middlewares, no one-asset assumptions, no re-plumbing your server for each network.

9/ EVM? Two paths:
• A simple direct-transfer scheme (client pays, sends tx hash) is trivial as a Faremeter plugin.
• A more robust settlement plugin (EIP-3009-style on-chain verification) is the natural next step. We’re actively looking to co-build this.

8/ Security & UX: the Solana settlement scheme includes protections against double-spend and front-running while supporting both “client posted” and “facilitator posted” flows. That means safer payments and fewer weird edge cases for builders.

7/ Compatibility: Faremeter aims to be a compatible superset of x402. If you stick to vanilla x402, you’re good. If you need advanced behaviors (different assets, chains, or wallet UX), enable a scheme and go. Composability without fragmentation.

6/ Example: Solana needs a recent blockhash so clients don’t have to hit an RPC. The facilitator supplies that via /accepts. It can be cached by the middleware and refreshed as needed. Result: fewer moving parts in the merchant server, more power at the edge.

5/ Architecturally, Faremeter differs from the reference x402 approach in a key way: our facilitator tells middleware what to send to the client via a lightweight /accepts endpoint. Middleware stays thin; the facilitator gathers chain-specific metadata.

4/ Why this matters: it decouples payment mechanics from the middleware. New chains, assets, and wallet types plug in as schemes. Implement a client + facilitator interface, and you’re in - no changes to the rest of the codebase.

3/ With this scheme, after the server returns 402 Payment Required, the client has two options:
• Ask the facilitator to land the transaction, or
• Post it themselves and have the facilitator verify it on-chain.
This covers agent, dApp, and server-driven UX - your choice.

2/ A common question: “How do smart wallets (e.g., @crossmint) actually pay + prove it?” On Solana, we shipped @faremeter/x-solana-settlement—a plugin that handles settlement end-to-end while staying within the x402 pattern.

1/ x402 for real apps needs flexibility.

We built Faremeter, an open-source, x402-compatible stack that makes it easy to accept crypto payments from smart wallets across chains - without locking you into one asset or one flow.
