Yield routing on Robinhood Chain

Predictable yield
on tokenized stocks.

Deposit AAPL, NVDA, GOOG, or USDG into an ERC-4626 vault. Yieldfy scores every connected venue on the same formula and routes your capital automatically.

No admin approvals. No black-box model.

A rules engine

Same inputs.
Same winner.
Every time.

Scoring is a fixed formula. Execution runs on Chainlink Automation with no human in the loop. Every rebalance writes a signed decision to the chain, so any route can be audited after the fact.

Protocol primitives

Built to run without someone watching it.

01

ERC-4626 Vault

Deposit a supported asset and receive vault shares. Custody and accounting remain on-chain.

02

Deterministic Optimizer

Same inputs, same allocation, every cycle. Each decision is signed and posted on-chain.

03

Autonomous Execution

Chainlink Automation checks for a rebalance every six hours. No server-side private key.

{ }

04

Simple SDK

Deposit, withdraw, positions, and the last on-chain decision through one compact SDK.

05

Venue Adapters

Morpho, Robinhood Earn, Uniswap, and Pleiades. New venues connect through one adapter.

06

Circuit Breaker

A guardian can return funds to the vault and pause routing while withdrawals keep working.

Scoring formula

Five inputs.
One winner.

Every venue is scored on five numbers, weighted and added together. The optimizer also estimates whether the extra yield is worth the gas and slippage.

Borrow demand, LP fees vs. impermanent loss, and volatility are evaluated with an equity-specific weighting profile selected at deposit.
