Build period

89 commits, first on 2026-09-18, latest 2026-09-22. Repository: github.com/Franlinozz/Kerb

Last test run finished 2026-09-21 07:01 UTC on commit c503f7a: 494 TypeScript tests passed (pnpm -r test) and 106 Solidity tests passed (forge test), with 0 failures.

Onchain

Every contract Kerb has deployed, with its verification status.

Terms posted so far: 1948 on chain 196, 2097 on chain 1952. Builder Code decoded from the calldata of the most recent transaction: kt0hl6xyhlx8xmt.

Data

The observation store is append-only: database triggers reject UPDATE, DELETE and TRUNCATE, so a number Kerb published can never be quietly revised.

Reproduce a report

The most recent report Kerb posted, for SLVx, observed 2026-09-21 23:13 UTC. Its inputs were canonicalised, hashed, and the hash was posted on chain with the report. The bundle itself is pinned to IPFS, so anyone can fetch the exact bytes and recompute every number from them.

Inputs hash

0x1a6bf806e148f6a2d11463820e68b253d9846b90a11578ff2fb770694c320956

Where the bundles are

1938 of 2487 distinct bundles posted in the last 24 hours can be fetched back

Every bundle posted after K-43 resolves from its inputsHash through the Kerb API. Earlier posts have a documented IPFS gap caused by the pinning quota. In the last 24 hours 1938 of 2487 distinct input bundles can be fetched back: 279 from IPFS and 1659 from this API.

Bundle CID

The CID is computed locally from the canonical bytes. This one is not on IPFS: the pinning account is over its plan limit, so the bytes are served by this API instead. Fetch this bundle.

Recompute it

Limitations

Where Kerb is running on a lower rung than it could, and what is testnet rather than mainnet. Stated here so nobody has to discover it from the code.
