Element Finance

Element has officially launched on Ethereum Mainnet with crvLUSD as their first asset. 

You can now earn a fixed rate of 9.5% on your crvLUSD. 

Or go further by becoming an LP in Element Pools and earn additional APY! 

Next week, Element will be adding a new term for crvTriCrypto (currently ~30% APY), followed by DAI and USDC as they pursue their mission of bringing new fixed rate primitives to the DeFi ecosystem.
