Stale-approval exposure on deprecated router
dYdX v4 (dYdX Chain)'s assessment for RD-F-168 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Cosmos reframe: no EVM router or ERC-20 approvals on the dYdX appchain itself. The Ethereum-side wethDYDX bridge contract (discontinued June 2025) may have residual user ERC-20 approvals but this is on Ethereum, not the appchain, and the bridge is permanently disabled. Exact residual approval count not enumerated. Gray: ERC-20 approval scanning pipeline not configured for Ethereum-side deprecated contracts in this assessment.
