CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
- Custom Logic: From
ERC-20/721/1155tokens to complex DeFi primitives and governance systems. - Gas Optimization: Every contract is optimized for efficiency, reducing user costs and improving scalability.
- Full Audit Trail: We provide comprehensive documentation,
NatSpeccomments, and test coverage exceeding 95%.
We deliver battle-tested code, not just prototypes. Our contracts are designed for mainnet deployment on day one.
Partner with us to move from concept to a secure, auditable codebase in as little as 2-4 weeks. We handle the entire lifecycle—development, testing, and audit preparation—so you can focus on your product.

Smart Contract Wallet Migration
Build vs. Partner with Chainscore
Compare the total cost, risk, and time required to migrate to smart contract wallets in-house versus with our expert team.
| Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Security Risk | High (unaudited custom code) | Low (audited, battle-tested patterns) |
Core Team Required | 2-3 Senior Solidity Devs + Security Lead | Your Product Team + Our Experts |
Key Deliverables | Custom architecture, untested migration scripts | Audited contracts, automated migration tooling, documentation |
Ongoing Maintenance | Your team (ongoing cost) | Optional 24/7 Monitoring & Support SLA |

STRUCTURED, LOW-RISK EXECUTION
Our 4-Phase Migration Process
A proven, methodical approach to ensure your smart contract wallet migration is secure, efficient, and minimizes user disruption. We manage the entire lifecycle from audit to deployment.
01
Phase 1: Discovery & Audit
We conduct a comprehensive security audit of your existing wallet architecture and dependencies. This includes a full analysis of upgrade paths, user state, and potential vulnerabilities to establish a zero-downtime migration blueprint.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy audit-ready smart contracts that form the foundation of your dApp. Our development process is built on security-first principles using Solidity 0.8+ and battle-tested libraries like OpenZeppelin.
From tokenomics to complex DeFi logic, we translate your business rules into immutable, gas-efficient code.
- Custom Token Contracts:
ERC-20,ERC-721,ERC-1155with tailored minting, vesting, and governance. - DeFi & DEX Modules: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming vaults.
- Security & Audits: Full unit/integration testing, formal verification, and preparation for third-party audits from firms like CertiK or Quantstamp.
- Gas Optimization: Every contract is optimized for lower transaction costs and maximum user savings.
We deliver a complete development package including technical specifications, deployment scripts, and documentation—enabling a 2-4 week MVP launch for most projects.
Technical & Commercial Questions
Smart Contract Wallet Migration FAQs
Answers to the most common questions from CTOs and technical founders about migrating to smart contract wallets.
Our phased approach delivers a production-ready migration in 4-6 weeks for standard projects. This includes 1 week for audit & planning, 2-3 weeks for development & testing, and 1 week for deployment and user onboarding. Complex multi-chain or heavily customized wallet logic can extend this to 8-10 weeks. We provide a detailed Gantt chart in the project kickoff.
