Settlement timelines may not be instant. (This is due to the applicable jurisdiction, payment rail used, cross-border nature of a transaction, settlement protocols, processing windows, and banking infrastructure involved, and may take up to seven days).

Third Party Payments

Use Case

• Onramp: Accept fiat payments from external bank accounts as a third-party source.

• Offramp: Disburse fiat payouts to external bank accounts that are not owned by the initiating end customer (e.g., vendor, beneficiary, or third party).

Key use case is for users to be able to offramp / send stablecoins into third party bank accounts:

• Crypto companies paying suppliers (USDC to EURO)

• Payroll originating in USDC to get delivered as USD or EUR into bank accounts

• Companies pay with stablecoins, freelancers receive fiat.

• Cross border payments

Customers from the USA can’t enable EURO 3rd party accounts.
