PROVEN METHODOLOGY
Our Development and Integration Process
A structured, four-phase approach designed to deliver a production-ready, secure, and scalable gasless infrastructure with minimal disruption to your core development.
01
Discovery & Architecture Design
We conduct a deep-dive workshop to analyze your user flows, define sponsorship models (paymaster), and architect a custom Account Abstraction (ERC-4337) solution. This phase establishes the technical blueprint, security parameters, and integration points for your specific use case.

SDK Development & Smart Contract Audit
Our engineers build your white-labeled SDK with key features like gas sponsorship, batch transactions, and session keys. Simultaneously, we develop and rigorously audit the core smart contracts (Account Factory, Paymaster) to ensure fund security and protocol compliance.

Integration & Staging Deployment
We provide dedicated support to integrate the SDK into your dApp's frontend and backend. The complete system is deployed to a staging environment (Testnet) for comprehensive testing of user operations, gas policies, and sponsor mechanics before mainnet launch.
