A created user with KYC approved and a verified bank account is required to buy crypto

Check Remaining Limits

For a more detailed explanation of how limits are calculated, please contact us.

Users can submit up to 4 transactions per rolling 24-hour period. Limits in that period are up to $3,000 USD for instant ACH, and up to $5,000 USD for standard ACH

The Calculate ACH limits endpoint returns the user's remaining daily and weekly limits by transaction type (Instant ACH or Standard ACH)

Transaction Minimums

Ethereum = $20

Polygon = $1.

We use device biometrics and linked bank account transaction history to determine each user's transaction limits.

Crypto Prices

Please see the fiat currencies and crypto token enum for formatting and network support.

Initiate ACH

When initiating a crypto purchase, you must present a transaction confirmation and required customer notices according to the Ratio UI requirements.

After submitting the request, you will get an activity ID in the response. Use this to monitor the transaction status.
