CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.

We build custom smart contracts that power your Web3 product, from initial audit to mainnet deployment. Our process delivers gas-optimized, secure code with a focus on long-term maintainability.

  • DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators, and automated market makers (AMMs).
  • NFT Ecosystems: ERC-721A, ERC-1155 marketplaces, dynamic metadata, and royalty engines.
  • Enterprise Solutions: Supply chain tracking, tokenized assets, and custom ERC-20 implementations.

Every contract undergoes rigorous security review using static analysis, formal verification, and testnet simulation before launch.

Deliverables include: comprehensive audit reports, deployment scripts, and documentation. We ensure your contracts are upgradeable and compliant with the latest EIP standards.

PROVEN METHODOLOGY

Our Security-First Development & Audit Process

From initial architecture to post-deployment monitoring, our end-to-end process is designed to eliminate vulnerabilities and ensure regulatory compliance for cross-border payments.

01

Architecture & Threat Modeling

We begin with a formal threat model, identifying attack vectors specific to remittance flows, multi-signature wallets, and compliance checks before a single line of code is written.

Contracts Threat Modeled
OWASP
Compliance Standard
02

Secure Development with Formal Verification

Contracts are built in Solidity 0.8+ using OpenZeppelin libraries. Critical logic for fund routing and fee calculations is formally verified using tools like Certora and Slither to prove correctness.

03

Multi-Layer Security Audits

Every contract undergoes automated analysis, manual review by senior auditors, and a final review focused on financial logic, oracle security, and regulatory hooks (e.g., OFAC sanctions).

Frequently Asked Questions

Get clear answers on our audit and development process, timelines, and security guarantees for your cross-border payment protocol.

Our process follows a structured 4-phase approach: 1) Discovery & Scoping (1 week): We analyze your requirements, tokenomics, and target chains. 2) Architecture & Development (2-4 weeks): Our team builds the contracts using Solidity 0.8+ with OpenZeppelin libraries, implementing features like multi-currency support and compliance hooks. 3) Comprehensive Audit (1-2 weeks): Our in-house security team conducts manual review and automated testing (Slither, MythX). 4) Deployment & Support: We assist with mainnet deployment and provide 90 days of bug-fix support. This ensures a predictable path from concept to live protocol.
