RAY Intro

Earn the highest rate in DeFi.


The Robo-Advisor for Yield (RAY) is a smart contract system that optimizes yield across various opportunities for an underlying asset.

Users deposit into a RAY token contract created for the underlying asset which specifies opportunities to rebalance between. An off-chain oracle monitors the opportunities, and sends transactions to RAY to rebalance funds with the optimal allocation.

Aave, Compound, dYdX

Aave, Compound, dYdX



At launch, each underlying asset (ETH, DAI, USDC) will have a RAY token which rebalances between all supported and live opportunities (Aave, Compound, DAI Savings Rate, dYdX). In the future, it may be useful to create a RAY token with less than the full set of opportunities, perhaps just Compound and dYdX. To show demand for a new RAY token, please comment in the RAY Discord.

RAY supports a generalized framework for opportunities, meaning new protocols and opportunities can be added to the system over time. Community members are encouraged to add proposals through YIPs (Yield Improvement Proposals), and add to the discussion and analysis of different ideas in the RAY Discord.


The current version of RAY does not charge product fees to users, and RAY pays the gas fees for rebalancing transactions.

Users pay gas fees upon depositing and withdrawing their assets.
