The onchain lending API.
Unified infrastructure for borrowing, lending, and advanced positions across protocols and chains, with safety and execution built in.
1delta provides the infrastructure required to operate onchain lending reliably across protocols and networks, with predictable execution and deep liquidity access.
1delta provides the core infrastructure required to build and operate onchain lending at scale.
These features abstract protocol complexity while enabling predictable, production-ready execution across markets.
Unified onchain lending API across protocols and networks
Composable, atomic execution for advanced lending and leverage strategies
Production-grade safety and reliability for operating real capital
One API. Infinite use cases.
Wallets and fintech applications integrate onchain lending to offer yield, borrowing, and capital efficiency to users. This requires abstracting protocol complexity, data, and safety.
- Unified lending access across protocols and networks
- Safe execution of deposits, borrows, and loops
- Real-time visibility into positions and utilization
“With 1delta, we enabled advanced lending features without months of internal development and testing.”
