+# A Bitcoin-Charged Crypto Economy with Trustless Vaults
+
+### Abstract
+
+Bitcoin is by far the largest crypto asset by market capitalization, yet the vast majority of it
+remains idle. Today, less than 1% of all bitcoins are bridged to smart contract platforms, where
+most decentralized finance (DeFi) activity takes place. A key barrier to greater participation is
+that existing Bitcoin bridges are either centralized or rely on significant trust assumptions. In
+fact, due to the lack of covenants in the Bitcoin scripting language, there are no known ways to
+build trustless Bitcoin bridges.
+
+We bypass this barrier by introducing a different primitive: trustless Bitcoin vaults. Bitcoin
+holders deposit their BTC into these on-chain vaults in a self-custodial fashion. The bitcoins in
+each vault are tied to a specific smart contract protocol on an external chain. These vaults are
+programmable, and withdrawals are permitted only when a zero-knowledge proof of a specific
+smart contract state is verified on the Bitcoin chain. Together with an appropriate Bitcoin
+scripting design of the vault, this eliminates the need for mutual trust among parties.
+We demonstrate how this construction enables the use of native Bitcoin—without wrapping or
+bridging—as collateral in many DeFi applications, including lending, stablecoin issuance, and
+perpetual DEXs. 
+
+Leveraging recent advances in BitVM3, we present experimental results
+showing that these vaults can be operated with minimal on-chain overhead—an essential
+requirement for scaling trustless Bitcoin-backed DeFi. Bitcoin vaults built on top of the Babylon
+Bitcoin staking protocol further improve capital efficiency by allowing staked BTC to act as
+collateral in DeFi protocols. We conclude by discussing how trustless Bitcoin vaults significantly
+strengthen the existing Babylon ecosystem and the utility of BABY as the token for its
+decentralized governance.

 ## Step 3: Wait for the Unbonding Period and Withdraw
-After you initiate the unbonding process, you need to wait for a specific period to complete the unbonding. Specifically, you must wait for 301 Bitcoin blocks (~2 days) to be mined, which typically takes around one week. This waiting period ensures the stability and security of the network.

This waiting period ensures the stability and security of the network. Note that in rare cases, network conditions could cause slight delays.

 Once the unbonding period has elapsed, return to the staking history list in your wallet. Locate the unbonded stake. For stakes that have completed the unbonding process, you will see a **Withdraw** button. Click on the **Withdraw** button to transfer the unbonded funds back to your wallet. After clicking **Withdraw**, confirm the transaction in your wallet, and the funds will be on their way to your wallet address.
