overview
BUILD

Custom Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol or application.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on audited security patterns and battle-tested frameworks like OpenZeppelin to mitigate risk from day one.

From concept to mainnet, we deliver contracts that are gas-optimized, upgradeable, and secure by design.

  • Protocol-Core Logic: Custom ERC-20, ERC-721, staking mechanisms, governance modules, and bespoke DeFi primitives.
  • Security-First Development: Rigorous internal audits, formal verification where applicable, and adherence to industry best practices.
  • Full Development Lifecycle: We handle everything from architecture and implementation to testing, deployment, and post-launch monitoring.

CORE SERVICE

Smart Contract Development

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

We architect and deploy audited, gas-optimized smart contracts that form the backbone of your Web3 product. Our development process is built on security-first principles using Solidity 0.8+, OpenZeppelin libraries, and comprehensive testing suites.

  • Token Standards: Custom ERC-20, ERC-721, and ERC-1155 with advanced features like minting, staking, and governance.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
  • Enterprise Logic: Multi-signature wallets, vesting schedules, and compliant KYC/AML integration modules.
  • Full Audit Trail: Every contract undergoes peer review and formal verification before mainnet deployment.

We deliver battle-tested code that reduces vulnerabilities and ensures your protocol's economic security from day one.

Frequently Asked Questions

Get clear answers on our development process, security, timelines, and support for your custom browser extension wallet.

A standard, production-ready browser extension wallet with core features (key management, multi-chain support, token/NFT display, basic swaps) takes 4-6 weeks from kickoff to launch. Complex projects with advanced DeFi integrations, MPC key management, or custom transaction builders can take 8-12 weeks. We provide a detailed sprint-by-sprint roadmap after the initial discovery phase.
