overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that form the backbone of your Web3 application. Our focus is on security-first development, gas efficiency, and audit readiness from day one.

  • Custom Logic: Build ERC-20, ERC-721, ERC-1155, and bespoke token standards.
  • DeFi Protocols: Develop automated market makers (AMMs), staking pools, lending vaults, and yield strategies.
  • Enterprise Systems: Create multi-signature wallets, DAO governance modules, and supply chain verifiers.
  • Security Foundation: All code follows OpenZeppelin standards and is structured for seamless third-party audits.

We deliver a fully tested, documented, and deployable contract suite, reducing your technical risk and accelerating your time-to-market.

ARCHITECTURE & EXECUTION

Core Technical Capabilities We Deliver

We build the foundational infrastructure for seamless, secure, and scalable cross-chain payments. Our modular approach ensures you get exactly what you need—no more, no less.

01

Smart Account Implementation

Deploy ERC-4337-compliant smart accounts with custom logic for multi-signature, session keys, and gas sponsorship. We ensure compatibility with major bundler networks for reliable user operations.

02

Cross-Chain Paymaster Infrastructure

Build a dedicated paymaster service that abstracts gas fees across EVM and non-EVM chains. We handle the complexities of gas token conversion and subsidy models for your users.

03

Intent-Based Transaction Routing

Implement a solver network that finds the optimal route for cross-chain payments based on cost, speed, and security. We integrate with leading bridges and DEX aggregators.

04

Security & Audit Integration

From the first line of code, we embed security best practices. Our deliverables include a formal verification report and are designed for seamless integration with third-party audits from firms like Trail of Bits.

05

Modular SDK & API Layer

Receive a production-ready SDK and REST/GraphQL APIs for frontend integration. We provide comprehensive documentation and client libraries for rapid developer onboarding.

06

Monitoring & Analytics Dashboard

Gain real-time visibility into payment flows, gas expenditure, and user adoption with a custom admin dashboard. We set up alerts for failed transactions and system health.
