Gearbox Protocol, a decentralized finance (DeFi) platform, has enhanced capital efficiency by allowing users to leverage assets across multiple protocols through credit accounts. This approach reduces the need for overcollateralization, which traditionally limits capital utilization in DeFi. Gearbox has expanded by deploying on layer-2 solutions like Arbitrum and Optimism, introducing incentives to boost adoption. The protocol aims to become a leverage layer for all of DeFi, enabling new products and protocols to build on its platform. Gearbox also envisions transforming into a leverage-enabled smart wallet, simplifying the use of leveraged funds across various DeFi protocols. With a strong security track record and no incidents of bad debt, Gearbox continues to innovate, recently launching Gearbox v3 to integrate more DeFi protocols and manage risks effectively.
