Across Protocol (HubPool): control-plane safety record

1 indexed control-plane surface for Across Protocol (HubPool), with its controller and timelock state pinned to a canonical Ethereum block over archive JSON-RPC (not EAS-attested; documentation parameters are linked, not compared). Contract: 0xc186fA914353c44b2E33eBE05f21846F1048bEda.

Provenance

RPC-pinned record: read over public JSON-RPC at the Ethereum block shown below and independently re-read at the same block by a second Pacta seat. It is not EAS-attested: no sprint number, no summary document and no Base EAS UID. Status RPC-observed baseline: the on-chain control plane is pinned at block height; whether it matches the protocol's documented parameters is not assessed here (the documentation is linked for reference). Machine-readable: /api/v1/rpc-pinned.json. The Base-EAS-attested Sprint records are in /api/v1/index.json.

Observed on-chain. AcrossHubPool (0xc186fA914353c44b2E33eBE05f21846F1048bEda) verified on Ethereum Mainnet at canonical block #26,414,499 (19,572 bytes runtime code). EIP-1967 implementation and admin storage slots are both zero (non-EIP-1967 contract). Direct owner() returns 0xB524735356985D2f267FA010D681f061DfF03715, verified via getThreshold() and getOwners() as a 3-of-5 Safe multisig.

Documentation (linked, not compared). Across Protocol (HubPool) documentation is linked for reference (https://docs.across.to/reference/contract-addresses/mainnet-chain-id-1; governance: https://forum.across.to/). This RPC-pinned record does not compare documentation parameters with the on-chain state.
