TallyPay overview
TallyPay is a developer platform for teams shipping x402 payments: open-source npm packages for servers and clients, plus an optional hosted layer for traces and dashboards.
Principles
Section titled “Principles”- No token — we sell software (documentation, retention, collaboration), not a speculative asset.
- Facilitator-neutral — use Coinbase CDP, thirdweb, or your own verifier; we don’t replace settlement.
- Honest scope — we make lifecycle events visible; we don’t guarantee chain finality—that’s still your facilitator and chain.
What you install
Section titled “What you install”| Package | Role |
|---|---|
@tallypay/core | Types, trace IDs, wrapFetch, event emitter to the collector. |
@tallypay/server | Express / Hono middleware for 402 + verify/settle + optional traces. |
@tallypay/react | Provider, hooks, client beacons for funnel analytics. |
What “hosted” adds (roadmap-aligned)
Section titled “What “hosted” adds (roadmap-aligned)”When the collector and dashboard are live for your account:
- Trace timeline — server and client steps for a single
traceId. - Conversion metrics — how many 402s become completed payments (unique to client instrumentation).
Until then, the OSS packages still work without an API key—payment gating functions; tracing is simply off.
