SGD	🇸🇬 Singapore Dollar
CAD	🇨🇦 Canadian Dollar

⚠️ Preview currencies are enabled for a limited set of merchants in production and may change before general availability. Reach out to your Bakkt contact if you'd like access.

ZMW & UGX — mobile money support

ZMW and UGX additionally support mobile money payouts, using the same mobile-wallet / bank-account rail model as KES and GHS.

Rail	`is_mobile_wallet`	Required fields
Mobile wallet	`true` (default)	`currency` + `recipient_phone_number`
Bank account	`false`	`currency` + `is_mobile_wallet` + `account_number` + `swift_code`

For mobile money payouts, the recipient's phone number must be associated with a supported mobile money provider for that currency. Retrieve the current list of supported banks and mobile money providers via:

GET /stablecoin/supported/banks?currency=ZMW
GET /stablecoin/supported/banks?currency=UGX

SGD & CAD — fixed-field bank account

SGD and CAD use the fixed-field bank account shape.

Currency	Required fields
🇸🇬 SGD	`account_number`, `swift_code`, `bank_name`, `recipient_relationship`, `remittance_purpose`
🇨🇦 CAD	`account_number`, `swift_code`, `bank_name`, `transit_code`, `recipient_relationship`, `remittance_purpose`

Please refer to the API reference for the required account and recipient information for each currency.

🇨🇴 Colombian Peso (COP)

The COP remote bank account schema is now available for off-ramp flows in Sandbox. COP requires some corridor-specific recipient information, including the recipient's national identifier.

Required fields

currency, account_number, swift_code, bank_name, national_identifier, recipient_relationship, remittance_purpose

Example

{
  "account_details": {
    "currency": "COP",
    "account_number": "020601089805504",
    "swift_code": "COLOCOBM",
    "bank_name": "Bancolombia",
    "national_identifier": "3214786174",
    "recipient_relationship": "Self",
    "remittance_purpose": "Salary"
  }
}

Please refer to the API reference for the complete request schema and supported values.

🏢 Corporate Bakkt Bank Account Closure

Corporate Bakkt bank accounts can now be closed through the Stablecoin API.

New endpoint:

POST /stablecoin/corporate/{corporate_uuid}/bank-account/bakkt/{account_uuid}/close

An optional reason may be included in the request body. This brings corporate account management in line with the existing user-level account closure functionality.

📖 ACH Pull — USD Bakkt Fiat Account Required

An important reminder when integrating USD ACH Pulls: before initiating an ACH Pull, the user must have a USD Bakkt fiat account.

Creating a linked bank account profile does not automatically create the USD Bakkt account, so make sure it has been created before initiating the pull. If it's missing, the pull fails with a 404 and an "account mapping not found" error.

Please review the updated ACH Pull documentation when implementing or troubleshooting this flow.
