Shiba Inu Developers Clear Final Milestone in LEASH v2 Upgrade

Shiba Inu Clears Final Step for LEASH v2 Migration
10/9/2025

Shiba Inu developers announced Tuesday that the long-delayed LEASH v2 migration will begin shortly, following security approval from Hexens for both the token and its migration contract.

The move resolves months of uncertainty caused by a hidden flaw in the original LEASH code. While initially marketed as a fixed-supply token, the v1 contract contained a rebase mechanism and a “hidden-in-plain-sight” control path, allowing pre-authorized proxies to alter supply. The flaw, dating back to 2020, was exploited earlier this year, causing a 20% increase in token supply and undermining confidence in the token’s scarcity.

LEASH v2 is designed to permanently close the loophole. The full token supply has already been minted into a multisignature wallet, and the contract cannot mint new tokens. During migration, v1 tokens will be locked or burned, with v2 tokens released proportionally to holders.

The redesign relies on OpenZeppelin ERC-20 libraries for simplicity and auditability, with advanced features to be added later through wrappers.

SHIB prices were down 1% over the past 24 hours, tracking a flat broader crypto market.
