Biconomy Sponsorship Paymaster
ERC-4337 paymaster service that fronts gas on behalf of end users so dApps can offer gasless UX. Two modes — full sponsorship (developer pays gas, post-paid invoiced monthly) and pay-in-tokens (user pays gas in ERC-20). All sponsorship limits (per-tx USD cap, per-user daily cap, allowed contracts, chain whitelist) are configured per project in the Biconomy Dashboard and enforced before /v1/quote returns a sponsored quote.
