Lepton Agent
Lepton is a community-maintained, Laravel-first PHP SDK for Circle's Developer-Controlled Wallets and the Arc network. It gives Laravel applications reusable, typed methods — src/Gateways/CircleRestGateway.php implements auth, wallet, transfer-estimate, transfer-observer and x402 gateways against Circle's w3s API with USDC on Arc — instead of each project re-implementing the same HTTP calls. It adds HTTP and CLI transports, verified webhook notifications via CircleWebhookVerifier, and testing fakes so apps can be built and tested without hitting the live API. Shipped as a Composer package with a PHPUnit suite, it is the kind of groundwork other Arc builders can depend on.
