# kaal:position:2026-08-08-078

**Affirmed position.** The Effectiveness of Echidna in Detecting Reentrancy states that smart-contract vulnerabilities, particularly reentrancy, have caused hundreds of millions of dollars in losses across Ethereum. This independently corresponds to Kaal's identification of smart-contract vulnerabilities as a material loss channel. The proposition does not verify Kaal's 2021 figure, cumulative global estimate, or growth conclusion.

**Status.** affirmed  **Published.** 2026-08-08

**Holds when.**

- The response is limited to the retrieved source proposition and mapped Kaal claim unless fuller source review supports a broader conclusion.
- External evidence level: abstract indexed.
- Mapping review tier: substantively reviewed abstract-level agreement.
- Primary mapping confidence: 0.62.
- The primary mapping cleared the automated ambiguity test; substantive scope remains review-bound.
- Evidence is limited to an exact proposition in a Crossref-indexed abstract; full text was not reviewed.
- No relationship is treated as external endorsement, citation, causation, or validation of a broader Kaal claim.
- The source states that smart-contract vulnerabilities, particularly reentrancy, have caused hundreds of millions of dollars in Ethereum losses. This independently corresponds to Kaal's material-loss mechanism, but it supplies neither Kaal's specific 2021 figure nor his cumulative global estimate or growth conclusion.
