On-chain protection that verifies cross-chain mints and withdrawals in real time—providing a layered defense against compromised signers, bridge contract exploits, and more.
A bridge security layer that screens BTC bridge transactions against on-chain activity and confirms collateral backing before assets are minted or withdrawn cross-chain.
Sui Foundation has partnered with Cubist to support future integration of Bascule into the Lombard Bitcoin-Sui bridge, with the goal of reinforcing transparency and trustlessness in the minting of LBTC. When active, Bascule will serve as an independent attestation layer that verifies BTC deposits before minting LBTC on Sui. This mechanism is designed to help ensure that LBTC minted via the bridge is auditable and backed by actual BTC deposits — without relying on centralized trust.
“Bringing BTC into Sui is a match made in heaven. Thanks to this collaboration with Babylon, Lombard, and Cubist, users from all blockchain ecosystems can come to Sui to participate in a thriving ecosystem of financial services in which Bitcoin will play a key role.”
Protect yours by ensuring all mints and withdrawals are fully backed.
Don’t just detect bridge hacks—move towards preventing them. If Bascule detects a request that would imbalance funds on either side of the bridge, it pulls up the “drawbridge” before the suspicious request hits the chain.
Confirm that each mint of your token is backed by one BTC deposit, and each BTC withdrawal is backed by a token burn; prevent unbacked mints/withdrawals, double spends, and real funds being sent to the wrong recipient.
Process mints and withdrawals at native speeds: Bascule’s security checks don’t introduce a new (and slower) blockchain, so transactions remain as fast and efficient as the underlying network.
Maintain full control of your keys (and let your users keep custody of theirs, too). Bascule provides an extra layer of security without needing permission to sign transactions on your behalf.
Catch suspicious bridge transactions in real-time.
