Key Takeaways for Security Teams
- The audit needs to cover the exact deployed bytecode, re-verify after any last-minute change, however small it seems.
- Liquidity lock and multi-sig ownership transfer should happen before public announcement, not scrambled together after.
- Phishing clone sites are a launch-day risk that has nothing to do with the contract itself.
Most token launch failures are preventable and come from a small, repeated set of gaps: unaudited last-minute changes, unlocked liquidity, and multi-sig setups configured the day of launch instead of well before it.
Contract-Level Checks
These should be verified against the exact bytecode that will actually be deployed, not an earlier draft.
- •Final audit covers the exact commit hash being deployed, including any last-minute changes
- •Mint, pause, and blacklist functions are either removed or protected by a multi-sig/timelock
- •Supply cap and tokenomics match what has been publicly communicated
Launch-Day Operational Checks
A perfectly audited contract can still fail if launch-day operations are rushed.
- •Liquidity is locked (not just added) with the lock verifiable on-chain before any public announcement
- •Deployer wallet ownership has been transferred to a multi-sig before, not after, going public
- •Front-end contract addresses are verified and communicated through a single trusted channel to prevent phishing clones
