Stablecoin API v1.0.10 - Release Notes

🚀 Stablecoin API Update v1.0.10 is now live! 🎉

Token preferences now accept uppercase symbols, and off-ramp minimums are now per network.

✨ What's New

• 🔠 Uppercase token symbols on user and corporate token preference PATCH - USDC and usdc both work. agEUR, cEUR and cUSD keep their casing.
• 📉 Off-ramp minimums are per network, not per currency - 10 USD on Ethereum mainnet, 1 USD everywhere else.
• 🧪 Celo is production-only - not supported in Sandbox at the moment.
• 📦 Single-use wallets are not live on the Stablecoin path - the endpoint returns 200 {} without creating a wallet.
• 🇨🇦 CAD now supports Interac payments - a new beneficiary type has been added for Interac off-ramp payouts.
• 📱 Mobile money + phone format and mobile_provider for XAF (announced in v1.0.8) now in the OpenAPI spec.

📉 Off-Ramp Minimums

Set per network, not per payout currency, Ethereum mainnet is higher because of gas.

OMR and QAR also carry a currency-level minimum of 1 USD equivalent; the higher of the two governs.

⚠️ Below the minimum the transfer does not complete - you get a cryptoToFiat webhook with subType LIMIT_BREACHED, and the on-chain transfer cannot be reversed. Validate before the user sends.

Minimums are merchant-configurable, so read them at runtime instead of hardcoding:

curl --request GET \
     --url 'https://sandbox.api.bakkt.com/stablecoin/transaction/limits?limit_type=minimums&direction=OFFRAMP&input_chain=mainnet&input_token=usdc&output_currency=USD' \
     --header 'Authorization: API-Key YOUR_API_KEY'
