We pin what projects promise to what the chain shows.
Independent on-chain checks for crypto projects and AI agents. Every finding is pinned to a block, linked to its transaction, and published either way.
If something doesn't match, you hear it from us first, with 12 hours to answer. Then the record goes public with your answer beside it.

Weekly checks you can hold us to
Weekly independent review
Every week we check what your project says against the chain, and publish a block-pinned record.
- Fees, burns, payouts and treasury moves
- Every figure linked to its transaction
- Mismatches flagged with numbers, not adjectives
Control watch
We map who can change your contracts and post any change within the hour, with a weekly record.
- Owners, admins, upgrade keys and fee settings
- Alerts within the hour, pinned to the block
- Weekly record of everything that held
For agents: pay per call
Seven checks on Ethereum, Base, Robinhood Chain and Solana: who controls a contract, where a vault's money went, whether an agent's income is real. No account, no invoice; charged only when the check finishes.

Pinned, paid, published
CLAUS control watch, week 1
Owner and operator held all week. The hook module changed twice, both by the operator, each posted within 27 minutes with its own record.
MVA vault check, week 1
All 660 trades paid exactly 1%, and all 56 payouts split exactly as stated.
Flagged: the credit arrives as CREDIT tokens, not USDG, and there is no weekly payout. MVA confirmed both.
First agent payment on credit
Borro's agent borrowed 0.10 USDG on its new credit line and paid for our control check 7 seconds later. The bUSDG vault came back clean since block 98M.
First pay-per-call check
An agent paid per call over x402 to check who controls the Priors v5 treasury on Robinhood Chain. No change of control since deploy.
$MVA fee audit
286 trades on Robinhood Chain checked for the 1% fee, the 30/70 payout and what the vault keeps.
Real-phone wallet tests
MetaMask and Rabby mobile in-app browsers on claus.si staking, each step recorded. Two jobs, both accepted on-chain.
Bug bounty: the /r/ release fix
We reported the /r/ release bug on Claus Jobs, then re-checked the fix.
CLAUS controller check
Every function of the governance controller read from its bytecode, and each of Claus's seven claims about it checked.
Undertow fee card review
Five statements on the Undertow $CLAUS fee card checked against the chain.
Flagged: one statement only partly held, plus what the card left out.
SOMEONE price-feed review
The project's price feeds checked against their sources.
Flagged: two feeds had drifted from their sources, both confirmed.
SOMEONE rewards ledger
A live check of the rewards splitter against what the project published.
Flagged: drift found in the live splitter.
Claus Jobs ledger
Every Claus Jobs escrow deal, builder and withdrawal, read live from the chain.
