Minimum and Maximum Transaction Values

All values on this page are defaults and are merchant-configurable. Treat the tables as indicative and read the live figure from GET /stablecoin/transaction/limits before you transact — see Checking limits at runtime.

Fiat to Stablecoin Transactions — Minimum Values

Stablecoin to Fiat Transactions — Minimum Values

Off-ramp minimums are set per network, not per payout currency. Ethereum mainnet carries a higher minimum than every other supported chain because of its gas costs.

The minimum applies to the value of the stablecoin you send, is the same for every stablecoin on a given network (usdc, usdt, …), and does not change with the payout currency — an off-ramp from Ethereum mainnet to USD, EUR, GBP or NGN is subject to the same 10 USD floor.

OMR and QAR payouts additionally carry a currency-level minimum equivalent to 1 USD, calculated from the exchange rate at transaction time. Where a network minimum and a currency minimum both apply, the higher of the two governs.

Send less than the minimum and the transfer will not complete. You receive a cryptoToFiat webhook with subType LIMIT_BREACHED. Validate the amount in your UI before the user sends funds — on-chain transfers cannot be reversed. See Webhooks.

Checking limits at runtime

Always confirm limits at runtime rather than hardcoding these tables — they are merchant-configurable and change without a docs release:

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'

{ "limit_type": "minimums", "limit_amount": 10 }

Note the parameter is limit_type (snake_case). Passing limitType returns 400 with the message limitType expected "minimums", which is misleading — the message names the camelCase form while the API requires snake_case.

For on-ramp, swap the direction and its parameters: direction=ONRAMP with input_currency, output_chain, and output_token.
