Build on key management, not around it—and turn policy-enforced automation into the foundation for safe, scalable DeFi across chains.
Building in DeFi means designing for growth across ecosystems—not just surviving complexity, but scaling through it. It requires thoughtful design to maintain consistent performance, distributed control, and strong guarantees. Key management underpins this design, from speed—signing shouldn’t slow down your protocol—to decentralized governance—one or two bad actors shouldn’t be enough to destroy what you’ve built.
Go from whitepaper to reality, edge cases and all.
Lombard secures $2B in BTC with CubeSigner, generating Bitcoin keys programmatically and enforcing Babylon-specific workflows to restrict their usage—like ensuring deposits can only be staked to Babylon. Lombard maintains self-custody using multi-approvals, transaction limits, and timelock policies. To protect their Bitcoin bridges to Ethereum (and other EVM chains), Sui, and Solana, Lombard has chosen Bascule to independently verify that each LBTC mint is 1-to-1 backed by BTC.
“We’re proud to have Cubist enabling our vision of LBTC as a security-first Bitcoin primitive. Having extra protection from CubeSigner and Bascule on top of the Security Consortium helps us rest assured knowing that our protocol is guarded against the most common types of cross-chain bridge hacks.”
Launch more, worry less, and scale safely across ecosystems.
