Yieldcoin v2 Crosschain Vaults

Zealynx is reviewing Yieldcoin v2, the crosschain stablecoin yield infrastructure built by Contract Level, as a Season 1 Zealynx Audit Grant engagement. The review is anchored on the client's own security documentation - its stated invariants, pre-declared accepted risks, access control matrix and threat model - so a finding has to clear the bar the team already set for itself. Findings are raised as they are confirmed rather than all at once at the end, each carrying a severity and an evidence level that distinguishes proof-of-concept reproduction from source-level tracing. The engagement runs to a client remediation window and a mitigation review, with the written report following at the end. Scope, findings and the full report are being prepared for publication.
