These markets are based on stablecoin yields, and their rates are always changing (based on market supply and demand as covered in [How Nook earns Higher Rates](/overview/editor-1.md). Over the past year, the four markets (Seamless Morpho Vault, AAVE Core and Spark Morpho Vault) have averaged 8.3%, 7.2% and 5.4%, APY, respectively. So it might seem obvious to just go with the highest earning market. Not exactly. If we look closer into the details, having a range of five plus options to automate across has actually resulted in a 14.5% increase in earning rates. From an average of 8.3% → 9.5% APY over the past 365 days. ### Moving from one source to another Moving from one earning source to another is designed to be simple, fast, and free. It starts with USDC. You can deposit straight from your bank into USDC, then allocate from there with an internal transfer. From USDC, you can choose any Core or Frontier earning source available in Nook. You can also transfer funds directly from an existing earning source, including USDC, Core, or Frontier. Want to move from a Core source to a Frontier source? You can. Want to move from Frontier back to Core? You can do that too. Transfers within Nook typically take anywhere from 2 seconds to 20 minutes, depending on the source and network you select. You choose where your funds earn Nook. Allocation is in your hands. You can choose whether to move part of your balance or your full balance. You can decide which source you want to earn in, when you want to move, and how much you want to allocate. There are no transfer costs or fees across any supported source or network, including Base, Ethereum mainnet, Optimism, and World. To date, as part of these rebalances, Nook has processed over $100M in successful transactions through the platform. Paving the way to $1B in transactions.
