Ten questions from the ElasticSwap shadow audit debrief: the three real findings, the seven false positives that trap good auditors, and the method that separates a real finding from a reflex.

A bridge verifies a signed message and runs it. The signature is real, and that is the problem. Three questions on why a valid message can be replayed for a second payout.

A vault mints shares by dividing your deposit by its raw token balance. Anyone can send tokens straight to that balance. Three questions on the trap that leaves the next depositor with zero shares.

A governance contract reads voting power from your current token balance. Three questions on why a flash loan turns that read into a rented majority.

An airdrop verifies a Merkle proof and pays the caller, but the leaf commits only to an amount. Three questions on why a valid proof can claim the wrong person's tokens, and be reused until the pool is empty.

A lending protocol reads its price straight from the AMM pool reserves. It compiles, it is live and on-chain, and it is still exploitable. Three questions on the spot-price trap.

A price from Chainlink can still be wrong. Three questions on the freshness check a trusted feed does not do for you.

A staking reward is computed as amount over total, times a rate. The algebra is right and small stakers still earn zero. Three questions on where the value leaks.

A vault withdraw transfers the funds, then subtracts the balance. Three questions on the ordering flaw that lets a receiver re-enter and drain.

A call to an address with no code does not fail. It succeeds and does nothing. Three questions on the trap a zero-address check does not catch.

A vesting function returns the linearly vested amount since the start. The formula is clean and it still pays out before the cliff. Three questions on the boundary a linear formula does not catch.
