Deprecated contracts still holding value

Evidence summary #

Maple V1 deprecated December 11, 2022. Docs still reference V1 UI as accessible for three legacy pools. On-chain balances of V1 contracts not independently confirmed as zero. Likely below $100K threshold but not on-chain verified. Yellow pending curator confirmation.

Detail #

Maple V1 migration to V2 occurred December 11, 2022. Docs at https://docs.maple.finance/maple-1.0/maple-token-holders reference three V1 pools still accessible via V1 UI: Orthogonal USDC 01, Maven 11 USDC 01, Maven wETH 01. These are deprecated contracts with residual user positions that can still be claimed. The DefiLlama TVL data-cache records all TVL under the V2 slug; no V1-specific TVL breakout is available. Given the post-incident collapse (TVL from ~$900M to ~$20M in 2022-2023) and subsequent V2 migration, residual V1 pool balances are plausibly below the $100K material threshold — but this is not positively confirmed on-chain. F166 red threshold: > $100K in assets in officially-deprecated contracts. Score: yellow (surface still exists, material balance not confirmed as zero, curator action required for on-chain balance check). Not red because residual is plausibly below threshold; not green because V1 contracts are still referenced as active and no on-chain zero-balance confirmation exists.
