ETH, DAI or USDC is deposited from either a MetaMask wallet or a Ledger wallet connected to MetaMask into the RAY smart contract on-chain. In return, investors are issued a unique ERC-721 token that represents an ownership interest in the RAY liquidity pool with matching opportunities.
The RAY smart contracts are generally available on Ethereum for anyone to access. Staked also offers an easy to use interface, which can be accessed here.
