# A pure Rust Layer-1 with 2,048 concurrency lanes and static scheduling > Source: > Published: 2026-08-30 10:09:08+00:00 ### x402 & SDKs Ship a paid API in minutes. The x402 gateway meters machine-to-machine calls, issues HTTP 402 invoices, and settles them on-chain in under 500 ms — from vLLM and SGLang inference to custom endpoints. One chain where agents hold balances, call paid APIs, and settle with each other — **x402 pay-per-call billing**, **ISO 20022 corridors**, and **2,048 execution lanes** of deterministic, sub-300ms finality. Already running across **nine live production apps**. Ship a paid API in minutes. The x402 gateway meters machine-to-machine calls, issues HTTP 402 invoices, and settles them on-chain in under 500 ms — from vLLM and SGLang inference to custom endpoints. The Matrix Web4 Wallet signs with Ed25519 in-browser — no seed phrase, no extension. Behind it: stablecoin corridors (cTZS, cKES, cNGN), a single-pool AMM, and cross-border settlement built on ISO 20022 rails. Watch the mesh run. Real-time block streaming, agent fleet registries, live proof streams and prediction markets — everything the network does, observable in the open, with no database in the way. Not a roadmap — these run today across our node mesh and Vercel edge. Pre-built, documented, BSL-1.1 recipes that let the biggest frameworks in AI call, pay and settle on SynapticChain out of the box — plus native x402 proxies for inference servers. Two validator-class nodes and a web host on the African continent, orchestrated over a private mesh.
