What is Ratio?

Ratio helps Web3 wallets and applications increase user activation and engagement by making it easy for users to exchange USD for USDC or the base asset of the supported network. Their goal is to be the most reliable, lowest-cost way to program USD to crypto payment flows. Card ramps work 30% of the time when exchanging USD for crypto. Ratio is as reliable as making a deposit to Venmo.
