Frequently Asked Questions on Upgrade Custody
Get clear answers on how Chainscore Labs manages the critical process of secure smart contract upgrades for your protocol.
Our standard upgrade custody deployment takes 2-4 weeks from kickoff to mainnet execution. This includes a 1-week discovery and planning phase, 1-2 weeks for development and internal testing of upgrade scripts and timelock configurations, and a final week for client review, staging environment deployment, and the mainnet execution ceremony. Complex multi-contract migrations or cross-chain upgrades may extend this timeline, which we scope and quote for upfront.
