Deprecated contracts still holding value
Sanctum's assessment for RD-F-166 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
No Sanctum-announced deprecated contract holds >$100K in stranded user assets. The has_legacy_v1: true flag in profile meta refers to the unstake.it predecessor product rebranding (July 2022), not a separately-deployed idle contract. The Unstake Program is feature-frozen (last commit 2024-11-20) but still actively serving traffic and holding the SOL Reserve pool — it is not a deprecated program per any official announcement. Infinity V2 (March 2026) was an in-place BPF upgrade at the same program address; no separate V1 contract address was retired and left holding value. No EVM deprecated router with stale ERC-20 allowances applies (Solana is the sole chain). CHANGELOG.md documents v1.0.0/v2.0.0 as implementation versions of the same deployed program, not separate on-chain addresses.
