Overview: OnMeta vs Alchemy Pay vs Simplex

Provider | Typical Fee Structure | Important Considerations |
OnMeta | Pricing depends on the local payment rail, transaction route, asset, and business integration | Businesses should review the quoted rate, network charges, and final crypto amount delivered |
Alchemy Pay | Processing fees vary by payment method and region; card purchases may carry higher fees than local bank or wallet payments | Network fees may apply, and the final crypto amount can change with market rates and settlement timing |
Simplex | Card fees generally range from 3.5% to 5%, with a minimum charge of $10 | Smaller transactions may face a higher effective percentage because of the minimum fee |
