Key benefits:
- Enhanced scalability through OP Stack infrastructure
- Unified yield opportunities across chains
- More connected DeFi ecosystem
This expansion demonstrates how modular blockchain frameworks like OP Stack are enabling the next generation of cross-chain DeFi applications.
DeFi built different starts with networks built for scale. OP Stack chains including OP Mainnet, @fraxfinance, @modenetwork, and @base are among the 18 powering Ethena鈥檚 expansion with OVaults facilitating a more connected DeFi ecosystem for seamless cross-chain yield.
