Seamless Protocol (Base): control-plane safety record

1 indexed control-plane surface for Seamless Protocol (Base), with its controller and timelock state pinned to a canonical Base block over archive JSON-RPC (not EAS-attested; documentation parameters are linked, not compared). Contract: 0x0E02EB705be325407707662C6f6d3466E939f3a0.

The pre-flight API re-reads the controller, proxy and capabilities of a contract at the latest block. No key, no wallet.

Provenance

RPC-pinned record: read over public JSON-RPC at the Base 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.

Pinned block: Base #57,421,449 · RPC-pinned, not EAS-attested

Controller: No single-key owner or admin getter (immutable or role-scoped modules)

Observed on-chain. SeamlessPoolAddressesProvider (0x0E02EB705be325407707662C6f6d3466E939f3a0) verified on Base Mainnet at canonical block #57,421,449 (9,779 bytes runtime code). EIP-1967 implementation and admin storage slots are both zero (non-EIP-1967 contract). No single-key Ownable or ProxyAdmin getter exposed on the primary entry contract; permissions follow immutable or role-scoped module architecture.

Documentation (linked, not compared). Seamless Protocol (Base) documentation is linked for reference (https://docs.seamlessprotocol.com/technical/smart-contracts; governance: https://seamlessprotocol.com/). This RPC-pinned record does not compare documentation parameters with the on-chain state.
