Protocol
What can be checked about the contracts, and what the last check returned. Observations with their block heights; the verdict is yours. There is no safety score on this page and none will be added.
Everything below describes Arbitrum One only. Mainnet and testnet run different contract builds, so a testnet observation is not a mainnet fact and the two are never mixed on one page. A promise that did not settle says so, and a bytecode match reads “unchecked” where deployed code has not been compared against verified source.
What can be checked
Five structural claims, each with the check that would falsify it and what that check returned at a stated block. Every figure below is read live from /v1/verify/bundle — this page states no claim the endpoint did not observe, and draws no conclusion from it. Any verdict is yours.
On Arbitrum One, the only token admitted as collateral is WBTC; USDC and USDT are admitted as loan tokens. Admission is controlled by ListingService.setCollateralWhitelist, listed in the privileged-function map above and held by the 2-of-3 multisig — and it affects new auctions only. It cannot reach an existing loan.
Observed 2026-08-27 via the MCP tool get_protocol_reference. This list is not rendered live: no REST endpoint publishes it, so it cannot be fetched the way every other figure on this site is (§0.2). It is stated here with its source and its date rather than omitted, and it is the one figure on this page a reader should re-check against the chain rather than trust from the page.
Gavel is registered as agent 201 in the ERC-8004 identity registry at 0x8004A818BFB912233c491871b3d84c89A494BD9e. That registry is on Arbitrum Sepolia (eip155:421614) — the testnet. The registration resolves: tokenURI(201) returns the agent registration file served from this estate, verified 2026-08-27. There is no mainnet registration, and this page does not imply one.
