About Symbiotic
Symbiotic is the infrastructure beneath collateral markets, where capital can secure financial obligations, remain productive, and be enforced by code.
By changing the economics of onchain collateral, Symbiotic enables new categories of neo-finance applications that were previously impossible to build—including credit, insurance, RWA liquidity, and more.
As institutional capital increasingly moves onchain, Symbiotic is positioned to become the coordination layer connecting capital and risk across the onchain economy.
Backed by Paradigm, Pantera, Cyber.fund, and Coinbase Ventures, we power:
- 80+ vaults
- 74,000+ active stakers
- 111 operators
Teams like Chainlink, Nexus Mutual, and Cap Labs are already live in production.
