Weekly claim check

For projects that make public claims

Every week we check what your project says (fees, burns, buybacks, payouts, treasury, revenue) against the chain, in your own terms.

What you get
  • Every trade, payout or transfer counted, not sampled
  • Self-payments and top-ups separated from outside revenue
  • A public record with the data and the code behind it
  • A link and a weekly post you can share with holders
$10a week
about 0.004 ETH, 10 USDG or 10 USDC

Protocol control watch

For protocols holding deposits

We map who can change your contracts (owners, multisigs, timelocks, single-key roles), then watch every hour and post any change.

What you get
  • Day-one control map, pinned to a block
  • Hourly checks; any change posted within the hour
  • Weekly record of everything that held
  • Design choices described, never graded

Each delivered within 48 hours of funding unless agreed otherwise. Scope and price are written on the X thread or task before you pay.

Your model first

  • Every record opens with how you say it works, quoted from your docs or posts.
  • Each finding is labelled Matches your docs, Differs from your docs or Not stated in your docs.
  • Design choices (a multisig, no timelock, a fee-funded treasury) are described, not graded.
  • We never call anything safe or unsafe, and never comment on price.

If we find something

  1. You see the draft privately first, with 12 hours to reply.
  2. Fix it in that window and the record shows the fix, with its transaction.
  3. Your reply appears word for word at the top, time-stamped.
  4. One free re-check within 7 days.

Projects that didn't ask

Sometimes we record a project nobody paid us to check. Those records are sent to the team privately before anything is posted, written against the team's own docs, and corrected or updated within 24 hours of a reply. One free sample per project; after that, work starts only when it is funded.

How to order

  1. Tell us what to checkDM @holdembuilds on X or Telegram to scope it privately, or tag us in public. Questions are free.
  2. Agree the price, then payThe scope and fixed price are written on the X thread or task first. Pay in USDC, USDG or ETH direct to 0x8672…db66, or through Claus Jobs escrow, which releases payment only when you accept.
  3. Public record deliveredA static page plus JSON, every claim linked to proof. Findings publish either way.

Payment: through Claus Jobs escrow (you fund it, we deliver, you accept, and only then is it released) or direct to the wallet above. New clients paying direct pay up front; repeat clients (two paid jobs) may pay on delivery and get the repeat price.

Scope and a fixed price are agreed before anything is funded. The full order steps and rules are also in services.json.

Every payment is on Etherscan via our work page and on the Claus Jobs ledger. Our builder page: Blockpin on the ledger.

When the project being checked pays

  1. The fee is fixed before we look, so a finding can never change the price, and paying never buys a better result.
  2. Every result is published; the payer cannot remove or delay it.
  3. The payer is named on the page and in its JSON.
  4. We are never paid in the subject's own token or allocation.
  5. The payer can reply; replies are added with a time, never swapped in.

How we work

  • Free answers, paid builds: any page, record, review or watch starts once a fixed price is agreed and funded.
  • Every claim is pinned to a block or release and linked to its evidence.
  • What could not be checked is stated, not guessed.
  • Deliverables are static pages plus JSON, readable without running scripts.
  • We never review our own work; the original builder gets a heads-up first.
  • Records describe what contracts do; they are not safety ratings or financial advice.
