Blockaid said the attacker used a flash loan to mint inflated tranche shares and then redeemed the vault's remaining USDC across about two transactions; a later balance check showed no USDC left in the vault contract. The stolen funds were bridged to Solana. Neither Fence Finance nor Valinor Digital had published a statement, and whether the vault was paused or fixed was unconfirmed. en Wed, 28 Oct 2026 00:00:00 GMT Avalanche Tranche Vault tied to Fence Finance and Valinor drained of 1.01M USDC in flash-loan exploit: On-chain checks show the vault holds no USDC; funds moved to Solana; Fence Finance and Valinor Digital have not commented. https://pwn.watch/i/fence-finance-avalanche-tranche-vault-drain-oct-2026 https://pwn.watch/i/fence-finance-avalanche-tranche-vault-drain-oct-2026#2026-10-28-a795afa6 Wed, 28 Oct 2026 00:00:00 GMT medium <p><a href="https://thedefiant.io/news/hacks/tranche-vault-on-avalanche-drained-of-1-01-million-usdc">Source</a></p> Avalanche Tranche Vault tied to Fence Finance and Valinor drained of 1.01M USDC in flash-loan exploit: Attacker uses a flash loan to mint inflated tranche shares and redeems about 1.01M USDC from the vault in roughly two transactions; Blockaid flags it as an ongoing exploit. https://pwn.watch/i/fence-finance-avalanche-tranche-vault-drain-oct-2026 https://pwn.watch/i/fence-finance-avalanche-tranche-vault-drain-oct-2026#2026-10-27-944cd1d9 Tue, 27 Oct 2026 00:00:00 GMT medium <p><a href="https://x.com/blockaid_/status/2115249066787340562">Source</a></p>
