Earnbase derives APY from each vault's on-chain exchange rate. This measures the actual growth of deposited USDC over time, based on the vault's smart contract data. Unlike some aggregators, Earnbase does not include external reward incentives, points programs, or token emissions in the displayed APY. The rates shown reflect native vault performance only.

While USDC is a stablecoin pegged to a fiat currency, the protocols generating yield carry smart contract risk. Higher APYs may indicate newer protocols, lower liquidity, or more aggressive lending parameters. Each listing on Earnbase includes TVL and a yield sustainability score to help assess risk. Always verify directly with the protocol before depositing.

Earnbase currently tracks 160 USDC yield strategies across 7 networks from 28 platforms. The largest coverage is on Morpho (64), Euler (19), and IPOR Fusion (16). New strategies are added as they meet inclusion criteria.

USDC APY varies significantly across platforms and networks. On Earnbase, tracked strategies range from under 1% to over 104%. Rates above 8-10% typically involve more complex strategies such as leveraged looping or private credit, which carry additional risk. The average APY across all tracked USDC strategies provides a useful benchmark, shown on each vault's detail page.

Yes. Earnbase tracks USDC strategies on Ethereum (74 strategies), Base (45), Arbitrum (20), Avalanche (9), Sonic (6), BNB Chain (5), and Katana (1). Use the network filter tabs above the table to compare APY rates on a specific chain. Each network has different gas costs, bridge requirements, and liquidity depth.

No. Earnbase is a free yield data aggregator. There are no fees for using the tracker or accessing yield data. Earnbase does not hold or manage funds. Links to individual vaults direct you to the protocol's own interface where you can deposit or withdraw.

Prime vaults lend against blue-chip collateral like wstETH and typically offer lower but more stable APY. Frontier vaults accept a broader range of collateral assets, which increases yield but also introduces more collateral risk. The tier name reflects the curator's own risk assessment.

Borrowing demand and liquidity supply vary by network. Base often has thinner USDC supply relative to demand, pushing rates higher. Ethereum Mainnet has deeper liquidity, which generally compresses rates. The same vault from the same curator can produce different APY on each network.

The sustainability score measures how consistent a strategy's yield has been over the past 30 days on a scale of 0 to 100. A score above 90 means very stable returns. A score below 50 indicates significant rate volatility. It helps distinguish reliably productive strategies from those with spiking rates.

No. All APY figures on Earnbase reflect on-chain vault performance only. External incentives like governance token rewards, points programs, and liquidity mining emissions are excluded. This means rates shown here may appear lower than on other aggregators that include temporary incentives.
