Deprecated contracts still holding value
ether.fi's assessment for RD-F-166 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
T-NFT (0x7B5ae07E2AF1C861BcC4736D23f5f66A61E0cA5e) and B-NFT (0x6599861e55abd28b91dd9d86A826eC0cC8D72c2c) contracts represent the pre-LiquidityPool v1 architecture (retired when pooled eETH model launched Nov 2023). Both still listed on deployed-contracts page without explicit 'deprecated' annotation. B-NFTs originally bonded 2 ETH per validator (v1 model). On-chain balance quantification not confirmed. Yellow (not red): NFT-type structure limits concentrated exposure vs. a pooled value contract; no evidence of >$100K single-contract ETH balance confirmed; but functionally-deprecated surface is still listed as active without formal deprecation notice. Curator follow-up required.
