hazethe 48-hour pre-launch check
one contract, checked before it holds real money. a manual security pass, tests on the paths that can lose funds, gas savings and a deploy checklist. a written report within 48 hours of kickoff, and the fixes.
what you get
- a line-by-line review: access control, reentrancy, rounding, oracle use, signatures and replay, token edge cases
- fuzz + invariant tests for the riskiest paths, added to your repo so they keep running in ci
- a gas snapshot and the biggest safe savings, with before / after numbers
- deploy readiness: constructor args, roles, ownership on a multisig, verification, upgrade and pause setup
- a written report ranked by severity, in plain english, with a fix for every finding
- one re-check after you apply the fixes, so the report matches what ships
scope
- one contract or a small set, up to about 500 lines of solidity (not counting tests and imports)
- foundry or hardhat, any evm chain: ethereum, base, arbitrum, optimism, hyperevm and the rest
- bigger codebases get a regular review with its own scope and price
want to see the list first? the pre-launch checklist is free. the check is me running it on your code, plus tests and fixes.
how it works
- 01 · send itrepo link (or a read-only invite for private repos), the commit to review, chain and launch date.
- 02 · kickoffyou get the fixed price and a start time. the 48 hours run from kickoff.
- 03 · reportfindings by severity, tests, gas numbers and the deploy checklist, with fixes.
- 04 · re-checkapply the fixes, i check them once more. then ship.
questions
is this an audit?
it is a focused review by one experienced engineer. it catches the common, expensive mistakes before launch. if your contract will hold a lot of value, you still want a full audit; this makes that audit faster and cheaper because the easy findings are already gone.
what does it cost?
a fixed price for the scope above, sent in my first reply before anything starts. no hourly billing.
what does 48 hours mean?
the report lands within 48 hours of the agreed kickoff time. we agree the kickoff when you book, so you can plan your launch around it.
my repo is private. is that ok?
yes. add a read-only collaborator, or send a zip of the commit. nothing is shared or published.
what if you find something critical?
you hear about it right away, not at the end, with a proposed fix. the report still follows on time.
book a check
a few lines is enough. you get the fixed price and a kickoff time back. the same person who built the free dev tools on this site reads your code.
need more than a check?
- smart contract developersolidity contracts from a spec (or a napkin) to verified mainnet code: tested hard, gas-aware and documented so your team can own it.
- dapp developerthe whole product, not just the contract: a fast next.js frontend, wallet connect that works on phones, contract calls that never confuse users, and a ui people enjoy.
- hyperliquid developerhyperevm contracts that talk to hypercore, trading tools and dashboards on hyperliquid’s api: the same work behind the free hyperliquid tools on this site.
- smart contract security reviewa careful second pair of eyes before you ship: manual review, the tests that find real bugs, a written report in plain english and the fixes, at a price that makes sense before (or instead of) a big audit firm.
- token & nft developertokens and nft collections done right: the contract, the mint page, the allowlist, the airdrop and the verified launch, with no surprises in the code.
- defi developerdefi that holds up under pressure: vaults, staking and integrations with the protocols you build on, with invariants tested before real money touches them.
