Frequently asked questions

Is Tollbeam a Paymaster?

Tollbeam is an aggregator that routes to multiple Paymasters. You keep your wallet and bundler; we only optimize sponsorship.

What is token‑gas spread?

In token‑gas mode, partners can pay in USDC. We bill the USD value of gas plus a small configurable spread (bps) to cover liquidity and risk; fallbacks ensure reliability.

How is the 15% adoption reward calculated?

We share 15% of net fees. Net per UO = fee × (1 − 0.15) − provider_cost. Multiply by UOs/day to estimate daily net.

Which chains are supported?

Start with OP Sepolia, Base Sepolia, and Polygon Amoy; enable mainnets as your project grows.

Do you store private keys?

No. Bring your own wallet, bundler, and signer. We manage routing logic and telemetry.

What SDKs are available?

JS/TS SDK is first‑class; REST is available for server‑side. More languages on the roadmap.

Ready to route your first UserOperation?

Create a project, grab an API key, and point your AA client to Tollbeam. Keep your current wallet/bundler; just add smart routing.
