A vault on Base was drained this morning, Oct-04.

• Taken: 1,783.067 wstETH, about $6.0M at today's price (our own calc: Lido's stETH-per-wstETH rate times ETH).
• Where it is: at 10:47 UTC the wallet behind it, 0x0B5126e1bc27C0de77e02e97945760A674EdB034, moved 1,782.067 wstETH to 0xC73448432a05deeA5Ea18a07D3b5d9ccf6297f8D, which got 0.03 ETH from the same wallet before the drain. The coins are still there.
• Route test: that address sent 1 wstETH to Ethereum through Lido's official Base bridge and proved the withdrawal at 10:43 UTC, four minutes before the main sum landed. If the rest takes the same bridge, it can't be claimed on Ethereum for about 7 days.
• Noise: zero-value transfers to look-alike 0xC734… addresses are address poisoning, not money moving.

The vault has no public label and its code is closed. If it's yours, reach out. We traced 100% of what left and keep watching.
