Deprecated contracts still holding value

Babylon Protocol's assessment for RD-F-166 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Non-EVM architecture. Babylon operates entirely on Bitcoin UTXOs (user-owned, self-custodial Taproot outputs) and Cosmos SDK native modules. There are no EVM singleton smart contracts to deprecate. The EVM contract-deprecation model (singleton address, on-chain deprecated() state, ERC-20 allowances) is architecturally inapplicable. Phase-1 BTC staking UTXOs are not 'deprecated' — they remain spendable by users via timelock/unbonding paths. Genesis chain upgrades (V2, V4) were in-place state migrations, not deprecated contract redeployments. Coverage flag has_legacy_v1: true reflects phase transition, not EVM contract deprecation.
