Introduction to the Bascule Bridge with Custodian-Managed Deposits
The Bascule Bridge enables seamless integration of Bitcoin into decentralised networks while leveraging trusted custody solutions. In this model, custody partners, such as Changer.ae, play a critical role by providing secure Bitcoin wallets specifically designed for deposits that initiate the bridging process. This hybrid approach combines Bitcoin’s inherent security with the robustness of institutional-grade custody, enabling a reliable and scalable pathway for minting oBTC on Proof-of-Stake (PoS) networks.
By employing custodial wallets in collaboration with trusted partners, the Bascule Bridge ensures secure tracking of Bitcoin deposits while maintaining transparency and decentralisation during the minting and redemption of oBTC.
How the Bascule Bridge Works with Custodian Wallets
Dedicated Custodian Wallets for Deposits
Custody partners, such as Changer.ae, provide dedicated Bitcoin wallets that are configured for bridge transactions.
Each wallet is managed with multi-signature security protocols, ensuring that deposited funds are safe and can only be accessed under predefined conditions.
Monitoring Custodian Wallets
Watcher Nodes actively monitor transactions to these wallets, verifying deposits in real-time.
Deposits are validated against specific criteria, including:
Confirmation depth to prevent double spending.
Transaction metadata that includes bridge-specific identifiers for tracking purposes.
Cross-Chain Communication
Once a deposit is confirmed, the Bascule Bridge generates a cryptographic proof and transmits the event to the destination blockchain using a trustless protocol.
The proof ensures that the deposit details are immutable and verifiable by the minting smart contract.
Minting oBTC on PoS Networks
On the PoS network, a minting smart contract processes the deposit proof and mints an equivalent amount of oBTC.
This ensures that the newly created oBTC tokens are always fully backed by the Bitcoin held in the custodian wallets.
Redeeming Bitcoin
When a user wishes to redeem their Bitcoin, they burn the corresponding oBTC tokens on the PoS network.
This burn event triggers a release from the custodian wallet, allowing the user to withdraw their Bitcoin.
Security Measures for Custodian Wallets
Multi-Signature Wallets: Custody wallets are protected by multi-signature protocols, requiring multiple approvals for any outgoing transactions.
Institutional-Grade Infrastructure: Custodian partners like Changer.ae leverage secure, compliant infrastructure to safeguard funds against cyber threats and unauthorised access.
Auditable Operations: All wallet activity is recorded on-chain, ensuring transparency and verifiability for users and third-party auditors.
Advantages of the Custodian-Managed Bascule Bridge
Simplified User Experience: Users can easily deposit Bitcoin into custodian wallets without the need to manage complex UTXO scripts.
Enhanced Security: Partnering with established custody providers ensures institutional-grade protection for user deposits.
Scalability: Custodian-managed wallets streamline the deposit process, enabling higher transaction throughput for larger-scale applications.
Transparent Backing: Each oBTC token is fully backed by Bitcoin held in verifiable custodian wallets, ensuring trust and accountability.
