Bridge uses same key custody for >30% validators
Chainlink CCIP's assessment for RD-F-156 — scored not_assessed on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Not assessable - Chainlink does not disclose key custody arrangements for DON or RMN nodes. Documentation claims geographic distribution but custodian details are not public. RMN design ensures no node overlap with DON (separate Rust implementation, different team) providing set-level key custody separation.
