Where fiat assets appear
The following account endpoints include the three fiat assets:GET /v1/balances: always returns all ten ledger assets, including zero rows. Fiat values use two decimals, for example"125.40".GET /v1/balances/history: includes a daily series for each fiat asset. Theavailablebalance is tracked; held amounts are exposed by the current snapshot.GET /v1/analytics/summary: includes fiat balances and volumes when they exist. USD valuation uses the organization rate feed (1 / local-per-USD); if no valid rate exists, the asset is reported as unpriced and excluded from USD totals.
Transfers
POST /v1/transfers permits a same-asset transfer when the source and
destination accounts use the same asset. A fiat transfer keeps its two-decimal
precision; it is not implicitly converted to USDT or another currency.
Product gates in v1
The ledger registration does not mean every product can spend fiat:
This separation is intentional: a balance can exist in the ledger before a
pricing or external settlement path is available.
Errors and precision
Amounts are decimal strings.1.50 BOB means 150 minor units; 1.234 BOB,
MXN or ARS is rejected. A fiat settlement request may be syntactically valid
but still return 503 pricing_unavailable until the fiat payout settlement
path is implemented.

Does adding a fiat asset change my default settlement asset?
No. Your default is unchanged. A fiat asset is only used
when explicitly enabled and accepted by the relevant product gate.
Can I use a fiat balance to pay a card purchase?
Can I use a fiat balance to pay a card purchase?
No. Cards reject fiat spending assets in v1; the balance remains visible and
usable by the products listed as supported above.
