I used to think self-custody was mostly about one question:
"Who holds the keys?"
After digging deeper into Trustless Bitcoin Vaults (TBV) from @BabylonLabs_io , I think there's a harder test:
Who controls the exit when something breaks?
So I went looking for the failure path in Babylon's docs.
What happens if a TBV peg-in doesn't complete?
On the current testnet, Babylon documents a refund path with a 3-day timelock. After that timelock expires, the depositor can use their Bitcoin key to recover the BTC without requiring the Vault Provider or another party to cooperate.
I stopped at the three days.
Honestly, it sounded slow.
Then I noticed what comes after the wait:
no permission required.
That changed how I read the number.
Three days is a UX cost.
Needing someone else's approval to recover my Bitcoin would be a custody cost.
Those aren't the same problem.
And I don't think the right conclusion is that three days suddenly becomes “good” because the system is trustless. Waiting is still a trade-off, and Trustless Bitcoin Vaults (TBV) still has application and cross-chain risks users need to understand.
But it gave me a better test for self-custody.
A deposit shows me how a protocol works when everything goes right.
The failure path shows me who actually has control when it doesn't.
That's the part of TBV I'm paying more attention to now.
If the choice were yours, would you accept a slower recovery path in exchange for an exit that doesn't depend on someone else's permission?
