How Modern Payment Infrastructure Untangles Complex…

AI summary of the source article
Modern payment software enables multi-currency conversions by separating the requested payment amount, the maximum a sender will spend, and the minimum a recipient must receive. On the XRP Ledger, these limits are programmable via fields such as SendMax, which caps the source amount excluding transaction costs, and DeliverMin, which sets a minimum floor for partial deliveries. When the partial-payment flag is activated, a transaction can deliver less than DeliverMax and still succeed. However, direct XRP-to-XRP transfers cannot utilize partial payments in this manner, and the delivered_amount metadata becomes final only once inside a validated ledger.
Why it matters
Setting distinct boundaries for what is sent and delivered allows software to execute currency conversions with precise tolerances. This broadens the payment options vendors can support while keeping the final outcome verifiable through validated ledger metadata.
Key facts
- SendMax caps the source amount excluding XRP transaction costs, while DeliverMin sets the floor for successful partial deliveries.
- The delivered_amount metadata field records what arrived and is only final once inside a validated ledger.
- Direct XRP-to-XRP transfers cannot use partial payments and are refused by the network.
