});
// 2. Sponsor any ERC-4337 v0.7 UserOperation in 1 call
const sponsoredOp = await arcrelay.sponsor(userOp);
// 3. User pays $0.00 gas. Network fees deducted from corporate tank.
await bundlerClient.sendUserOperation({ userOperation: sponsoredOp });How Corporate Gas Tanks Work
A secure bridge between enterprise treasury balances and consumer smart accounts.
Corporate Gas Tank Top-Up
Enterprises pre-fund gas in native USDC (or fiat credit card via Circle Onramp Kit) mapped to a unique bytes32 policyId.
0-Balance User Action
Consumer taps in-app action (swap, transfer, game move). No wallet popups, no gas calculations, zero native token needed.
EIP-712 Fraud Protection
The ArcRelay Policy Engine evaluates sliding-window spend quotas ($1.00/day default) and cryptographically signs authorization.
On-Chain Paymaster Settlement
ArcRelayPaymaster settles gas with Arc EntryPoint. Network fee is deducted from the corporate tank. User pays $0.00.
