ETH: Flash Loans

Included with Plus.

The number of flash loans on Ethereum each day, by protocol.

Why use it. Shows how often flash loans are used, separate from the size of each loan. How to read it. Stacked by protocol; the top of the stack is the total number of loans for the day. Compare with Flash Loan Volume to see the average loan size.

Calculation. Aave v2, Aave v3 and Balancer v2 on Ethereum mainnet, from each protocol's FlashLoan events on CryptoKeyhole's own node. A flash loan is borrowed and repaid in one transaction, so each counts once; the amount is the amount borrowed, valued like the DEX charts (dollar stablecoins at face value, ether-class tokens at the day's ETH/USD close, wrapped bitcoin at the BTC/USD close; other tokens count as loans but carry no dollar value). dYdX and other protocols are not covered, and repeated loans in one transaction each count. The history is read newest first and extends back toward November 2020, when Aave v2 opened.
