release: v1.7.5 — exact-amount WETH approval (#18)#22
Merged
Conversation
Bumps liquid-sdk 1.7.4 → 1.7.5 to ship the merged #18 security fix: bidInAuction approves SniperUtilV2 for exactly amountIn (was amountIn*10), leaving no standing WETH allowance for the drain-via-approval exploit class. Adds the [1.7.5] CHANGELOG entry (Security) with revoke guidance for users who bid through an older multiplier-approving SDK. No source changes — #18 is already on main; this is the version/changelog bump so the fix can be published to npm. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Version + changelog bump to publish the merged #18 security fix to npm.

#18 is a security fix with no public API change:
bidInAuctionnow approvesSniperUtilV2for exactlyamountIn(wasamountIn * 10n), so no standing WETH allowance survives a bid — closing the "drain via standing approval" surface (sibling Clanker fork, 2026-05). Complements the on-chainpaymentPerGasUnit == 0mitigation. Closes out G1.Verification
