Catch Runtime Bugs Before They Become Mainnet Incidents: CertiK Grey Box Chain Audit

CertiK's Grey Box Chain Audit is a runtime-focused security engagement that deploys a multi-node, realistic testbed to surface chain-critical failures (consensus, networking, oracles, bridges, upgrades, resource exhaustion) that static audits miss; an example engagement against Concordium produced 13 findings including two resolved critical denial-of-service issues, with deliverables including a test plan, runtime evidence, final findings, and a retained assurance harness for future testing.
