Our Upgradeability & Governance Framework
A structured, security-first framework for managing smart contract evolution in production payment systems. We deliver audited upgrade patterns and clear governance to eliminate upgrade risk.
01
Proxies & Upgrade Patterns
Implementation of audited proxy patterns (Transparent, UUPS) with dedicated proxy admin contracts. Ensures seamless logic swaps with zero data migration and preserved user state.

Smart Contract Upgradeability FAQs
Answers to the most common technical and commercial questions from CTOs and engineering leads evaluating upgradeability solutions for their payment infrastructure.
Our process is structured for clarity and security. We begin with a Technical Architecture Review of your existing system and requirements. This is followed by a Design & Specification phase where we architect the upgrade pattern (e.g., Transparent Proxy, UUPS) and draft the full technical spec. The Development & Audit phase includes building the upgradeable contracts, conducting internal security reviews, and integrating with your CI/CD. Finally, we manage the Deployment & Verification on-chain, including initialization and verification of all contracts. We provide a detailed project plan with milestones before any work begins.
