# The Yield Aggregator The yield aggregator powers the yield that depositors earn in the Orbit Earn Vault, it is a set of smart contracts and strategies that allocate and rebalance the deposited USDC across various crosschain yield venues. Quality real yields are the primary focus of the aggregator, taking into account various crosschain lending markets, vaults, yield-bearing stablecoins and RWA yields such as treasury bills. The aggregator focuses on optimising returns to give users the best risk-managed yields in real-time across the whole market without the need for users to manually rebalance, but it is done so in a risk-optimised way. The risk management parameters govern allocation: weighting based on yield types, yield risk-to-reward, individual protocols security and maturity, ease of access to withdrawal liquidity, market conditions, proper diversification and more...

## Rebalancing The yield aggregator rebalances every 4 hour period, except in the case an emergency rebalance is triggered (Risk parameter or large withdrawal, causing need for a rebalance). During this time the aggregator factors in different yields and how funds and currently allocated and moves assets around to various strategies if required. ## Trustless Interoperability with IBC Orbit is the first yield aggregator to be built completely on purely trustless interoperability by leveraging IBC, this removes many of the risks that yield aggregators often face leveraging traditional bridges to allocate and move assets cross-chain. With IBC, there are no centralised middlemen or multisigs for bridged funds, vastly reducing attack vectors that have been the cause of some of the greatest crypto exploits. Leveraging IBC v2 also enables greater speed, efficiency, lower cost and with its wider expansion enables Orbit to aggregate yields across Cosmos, Solana and EVM. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
