CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by Web3-native engineers.

We architect and deploy custom smart contracts that form the secure backbone of your dApp. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and upgradability from day one.

Production-Ready Code: Gas-optimized, well-documented contracts with a focus on security-first development.
Full Audit Support: We prepare contracts for third-party audits and can facilitate reviews with leading firms like CertiK or Trail of Bits.
Deployment & Verification: End-to-end handling from testnets (Sepolia, Holesky) to mainnet, with full source code verification on block explorers.

We deliver battle-tested contracts that power DeFi protocols, NFT marketplaces, and enterprise-grade applications with 99.9% uptime SLAs.

Our team specializes in complex implementations:

DeFi: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators.
Tokens: Custom ERC-20, ERC-721, and ERC-1155 with advanced minting and governance logic.
Cross-Chain: Contracts designed for interoperability using LayerZero or Wormhole.

A PROVEN, ZERO-DOWNTIME APPROACH

Our End-to-End Migration Process

We execute NFT collection migrations with surgical precision, ensuring zero downtime, guaranteed asset integrity, and a seamless user experience. Our battle-tested process has migrated over 5 million NFTs across major EVM chains.

1. Discovery & Strategy

We conduct a comprehensive audit of your existing contracts, tokenomics, and community structure. We deliver a detailed migration blueprint outlining timelines, risks, and a communication strategy for your holders.

2. Smart Contract Development

Our engineers build your new, upgraded smart contracts (ERC-721A, ERC-1155) with gas optimization, enhanced security patterns from OpenZeppelin, and future-proof upgradeability via transparent proxies.

3. Security & Audit

Every migration contract undergoes rigorous internal review followed by a formal audit from partners like CertiK or Hacken. We provide a public audit report to build trust with your community.

4. Migration Bridge Deployment

We deploy a secure, non-custodial migration bridge or snapshot-based claim contract. This enables holders to seamlessly move assets with a simple UI, preserving all metadata and provenance.

5. Testing & Dry Run

We execute the full migration flow on a testnet with a subset of real holder addresses. This validates the user experience, gas costs, and data integrity before mainnet launch.

Secure, audited smart contracts built for production from day one.

We architect and deploy custom smart contracts that form the immutable backbone of your Web3 application. Our development process is built on security-first principles, utilizing battle-tested patterns from OpenZeppelin and rigorous internal audits before any code touches the blockchain.

Production-Ready Code: Built with Solidity 0.8+ or Rust for Solana, following industry best practices for gas optimization and upgradeability.
Comprehensive Audit Trail: Every contract undergoes manual review and automated analysis with tools like Slither and Mythril. We provide a formal audit report.
Full Deployment & Verification: We handle deployment to mainnet/testnets, source code verification on block explorers, and initial configuration.

We deliver contracts you can trust, reducing time-to-audit by external firms by 60% and mitigating critical vulnerabilities before deployment.

Technical & Process Questions

NFT Migration FAQs

Get clear, specific answers to the most common questions CTOs and founders ask when planning an NFT collection migration.

A standard migration from ERC-721A to ERC-721C, including metadata optimization and a new minting dApp, takes 2-4 weeks from kickoff to mainnet deployment. Complex migrations involving custom traits, on-chain randomness, or multi-chain bridging can extend to 6-8 weeks. We provide a detailed week-by-week project plan during the scoping phase.
