First-depositor / share-inflation guard

Euler V2's assessment for RD-F-075 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

First-depositor / share-inflation guard confirmed present via multiple independent sources. Virtual deposit mechanism ensures exchange rate is well-defined even with zero shares, preventing rounding-based attacks. Vault.sol includes zero-share revert guard (E_ZeroShares). Rounding direction control (toSharesDown/Up) further constrains attack surface. Cantina 2025 security engagement confirmed no high/medium issues in these surfaces. The EVK was purpose-built to address this attack class as documented in Euler's own security blog.
