Smart Contract Wallet Upgrade Services

overview

CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, audited smart contracts built for your specific business logic and tokenomics.

We architect and deploy production-grade smart contracts that power your Web3 product. Our process delivers secure, gas-optimized code with full audit readiness, reducing your time-to-market and technical risk.

Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with tailored minting, vesting, and governance.
DeFi Protocols: Automated market makers (AMMs), staking pools, yield aggregators, and lending/borrowing logic.
Enterprise Logic: Multi-signature wallets, access control systems, and custom on-chain business workflows.

We don't just write code; we engineer resilient systems. Every contract follows OpenZeppelin standards, undergoes rigorous internal review, and is structured for seamless third-party audits by firms like CertiK or Trail of Bits.

Our deliverables include comprehensive technical documentation, deployment scripts, and post-launch support to ensure your on-chain foundation is robust and maintainable.

PROVEN PROCESS

Our Upgrade Methodology

A structured, security-first approach to upgrading smart contract wallets, minimizing risk and maximizing operational continuity for your users.

Architecture & Impact Analysis

We perform a deep technical audit of your existing wallet architecture to identify upgrade paths, dependencies, and potential breaking changes before writing a single line of code.

Smart Contract Wallet Upgrades

Frequently Asked Questions

Get clear answers on our process, security, and timelines for upgrading your wallet infrastructure.

A standard smart contract wallet upgrade takes 2-4 weeks from kickoff to mainnet deployment. This includes 1 week for architecture review and planning, 1-2 weeks for development and internal testing, and 1 week for client review, final audits, and deployment. Complex multi-chain or heavily customized upgrades may extend to 6-8 weeks. We provide a detailed project plan with milestones at the start.
