Wallets

Hold stablecoin and fiat balances for use across the Stablecoins API


Overview

A wallet holds a stablecoin or fiat balance and is the account every other stablecoin operation references — channels credit one, payouts debit one, and wallet transfers move funds between two.

A customer can hold at most 25 wallets.

Create the wallet

Requires an Idempotency-Key header.

FieldTypeRequiredDescription
nameStringYesWallet label, 3–100 characters.
currencyStringYesEUR, GBP, USD, USDC, EURC or USDT. The wallet's type (FIAT or CRYPTO) is derived from this automatically.
Request body
{
  "name": "My EUR wallet",
  "currency": "EUR"
}
Response 201
{
  "id": "6a4f0c9e-2d1b-4c8a-9f3e-b7d2a1c4e5f6",
  "name": "My EUR wallet",
  "type": "FIAT",
  "status": "INACTIVE",
  "currency": "EUR",
  "balance": null,
  "isTargetWallet": true,
  "createdAt": "2026-06-09T14:05:12+00:00",
  "updatedAt": null
}

The first wallet you create automatically becomes your target wallet — the wallet incoming stablecoin payments are credited to by default. Later wallets never do; set one explicitly via Updating a wallet if you need to change it.

Track provisioning

A new wallet starts INACTIVE while Volt provisions its deposit details — a bank account for a FIAT wallet, an on-chain address for a CRYPTO wallet — then activates automatically once ready. Poll the wallet until its status becomes ACTIVE:

The response also includes beneficiary (for a FIAT wallet) or crypto (for a CRYPTO wallet), each null until provisioning completes.

Wallet statuses

StatusDescription
ACTIVEThe wallet is usable.
INACTIVENot yet usable, typically while being provisioned; activates automatically.
TERMINATEDPermanently closed; cannot be reactivated.

Updating a wallet

PATCH /wallets/{id} renames a wallet, reassigns the target-wallet designation, or both — fields are applied independently, and at least one must be provided. The current target wallet can't be unset directly; set a different wallet as the target instead.
