Mixed-decimals math without explicit scaling

ether.fi's assessment for RD-F-017 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Core tokens (ETH, eETH, weETH) all use 18 decimals. Liquifier handles stETH (18 decimals) conversion. No mixed-decimal token math anomaly identified in sampled source. Certora FV reports for eETH share inflation and withdrawal fee cover core token math invariants.
