Gasless DeFi Aggregator Integration

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.

Protocol Development: Custom ERC-20, ERC-721, and ERC-1155 tokens, DeFi vaults, staking mechanisms, and DAO governance.
Security & Audits: Built with OpenZeppelin standards, followed by formal verification and third-party audit preparation.
Deployment & Management: Full lifecycle support from testnet to mainnet, including upgradeable proxy patterns and multi-signature wallet management.

Deliver a secure, auditable, and scalable smart contract foundation in 4-6 weeks, reducing your technical risk and accelerating your go-to-market timeline.

TECHNICAL DIFFERENTIATORS

Core Capabilities of Our Gasless Integration

Our integration eliminates the primary UX barrier to DeFi adoption by abstracting gas fees, while ensuring enterprise-grade security, speed, and reliability. Built for scale.

True Gas Abstraction

End-users never need native tokens for transaction fees. We handle gas sponsorship and settlement via meta-transactions or account abstraction, enabling seamless onboarding.

PREDICTABLE, SECURE, AND SCALABLE

Our Integration & Development Process

A structured, four-phase approach designed for technical founders to integrate a gasless DeFi aggregator with minimal risk and maximum speed. We deliver production-ready infrastructure, not just prototypes.

Architecture & Strategy Review

We conduct a deep technical audit of your existing stack and user flows to design an optimal gasless integration strategy. This includes selecting the right relay network (Gelato, Biconomy, OpenGSN), wallet abstraction patterns, and fee sponsorship models.
