Osmosis Freezes 22.65 BTC After Nomic Double-Spend Exploit

Osmosis has paused Alloyed BTC after a vulnerability on Nomic allowed an attacker to double-spend nBTC and send unbacked vouchers into Osmosis.

The security failure affected 39.84 nBTC held inside Alloyed BTC, representing roughly 36% of the asset's backing.

Osmosis' management subDAO halted Nomic and Alloyed BTC inflows and outflows after detecting the discrepancy, while validators coordinated an emergency network upgrade that froze 22.65 BTC at an address controlled by the attacker.
