An approved **Business** identity. * Note that Issuance is not supported for **Individual** identities at this moment. *** ## Core concepts ### Mint destination address A **mint destination address** is a blockchain address that you register so it can receive newly minted stablecoins for an identity. When you create a mint address, you provide the on-chain address, the chain, a label, and the identity ID. * Linked to an **identity** * Required before creating **mint instructions** — mint instructions reference a mint destination address by ID *** ### Mint instructions When you create mint instructions, Bastion returns **mint instructions** — the bank account details where the partner must wire funds and a **memo ID** that must be included in the wire. | Field | Description | | ----------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | | `memo_id` | **Required memo** — must be included in the wire. Bastion will use the memo ID provided on the wire to identify the sender and intent of the mint request | | `bank_name` | Receiving bank name | | `bank_account_number` | Account number for the wire (Bastion’s Stablecoin Bank Account) | | `bank_routing_number` | Routing number | | `bank_beneficiary_name` | Beneficiary on the account | The **memo\_id** links the incoming wire to the mint. Without it, funds cannot be matched to a mint request. Mint instructions are tied to one **identity** and one **mint destination address**. The partner must have registered that mint destination address before creating mint instructions. *** ### Bank account A **bank account** is a saved bank account that is provided by a partner to Bastion. A saved bank account will be used in the creation of a redemption instruction covered below. * Linked to an **identity** * Create once per bank account destination * An identity can have multiple bank accounts for different banks or purposes * Required before creating redemption instructions *** ### Redemption instructions **Redemption instructions** define where Bastion sends USD when the partner redeems stablecoins. They are tied to one **bank account** and one **identity**, and they produce a **redemption address** on a specific chain. * The **redemption address** is the on-chain address the partner sends stablecoins to initiate a redemption * When a Bastion Issued Stablecoin is sent to that address, the stablecoins will be burned and an equivalent USD is wired to the bank account tied to the redemption instructions *** ## Mint flow (USD -> stablecoin) High-level flow to mint Bastion Issued Stablecoin: 1. **Create Mint Destination Address:** Call [Create Mint Destination Address](/v2/api-reference/issuance/create-mint-destination-address) and provide wallet address to receive minted stablecoins 2. **Create Mint Instructions:** Call [Create Mint Instructions](/v2/api-reference/issuance/create-mint-instructions) and provide the mint destination address. Save the returned wire deposit details and unique memo ID 3. **Partner sends wire:** Partner sends a USD wire from their bank to the account in the mint instructions, including the **memo ID** in the wire details. 4. **Monitor status** — Via webhook or polling on [List Mints](/v2/api-reference/issuance/list-mints) until status `COMPLETED`. Stablecoin will be minted to the specified destination wallet *** ## Redemption flow (stablecoin -> USD) High-level flow to redeem Bastion Issued Stablecoin: 1. **Register a bank account:** Call [Create Bank Account](/v2/api-reference/issuance/create-bank-account) and provide destination bank account details 2. **Create Redemption Instructions:** Call [Create Redemption Instructions](/v2/api-reference/issuance/create-redemption-instructions) and receive the **redemption address** 3. **Partner sends stablecoin to redemption address:** Partner sends stablecoin from their wallet to the **redemption address**. This will initiate a redemption request 4. **Monitor status** — Via webhook or polling on [List Redemptions](/v2/api-reference/issuance/list-redemptions) until status `COMPLETED`. USD will be sent to the specified bank account. *** ## Related topics - [Mint Bastion-issued stablecoins with the Issuance API](/guides/quickstarts/mint-bastion-issued-stablecoins.md) - [Jurisdiction overview](/guides/getting-started/jurisdiction-overview.md) - [Issuance API overview](/v2/api-reference/issuance/overview.md) - [Stablecoin on-ramp and off-ramp conversions](/guides/concepts/stablecoin-conversions.md) - [Identities and accounts](/guides/concepts/identities-and-accounts.md)
