Formal smart contract audits catch vulnerability classes — reentrancy, overflow, access control. But they don't test whether your wallet connect flow works on mobile Safari, whether your dApp handles network switches gracefully, or whether your API layer regresses when contract addresses change.
Pre-mainnet QA bridges that gap. Teams that skip functional testing often discover critical UX and integration bugs days before launch — when fixes are expensive and reputational risk is highest.
What to test before mainnet
Wallet connection and signing flows across MetaMask, WalletConnect, and hardware wallets. Contract interaction paths including approve, swap, stake, and bridge operations. Cross-chain scenarios if your product spans multiple networks. API and indexer regressions when on-chain state changes.
In a recent engagement, QaLock caught 13+ critical bugs pre-mainnet — wallet disconnect edge cases, incorrect gas estimation display, and API failures on chain reorgs that audits wouldn't surface.
