FlowLink

What is FlowLink?

FlowLink is a straight-through-processing (STP) engine. You create a FlowLink once; Movmint generates a persistent DLT deposit address tied to an immutable conversion-and-delivery configuration. From then on, every deposit that arrives at that address is automatically:

detected and accepted,
screened for compliance,
converted at the current market rate (with your client-specific spread and fees), and
delivered to the preconfigured destination.

There is no quote, no capture, and no per-transaction approval. FlowLink is ideal for recurring or hands-off flows — for example, a persistent address that automatically converts incoming USDC to USD and pushes it to a bank account.

How FlowLink differs from Quote & Capture

Aspect	Quote & Capture	FlowLink
Pricing	Rate locked at quote time	Market rate at deposit time
Approval	Required (capture step)	Pre-authorized at creation
Deposit address	Ephemeral, per transaction	Persistent, reusable
Destination	Chosen per transaction	Immutable, set at creation
Flow	Interactive, multi-step	Automated, straight-through

Anatomy of a FlowLink

A FlowLink has three immutable parts plus a lifecycle status:

source — the asset and network the deposit address accepts. Source assets: USDC, EURC, ETH, BTC. Source networks: ethereum, base, solana, bitcoin. The deposit_address is generated by Movmint at creation.
destination — where converted funds go: a type (CARD, BANK_ACCOUNT, or DLT_WALLET), a target asset (USD, CAD, BSD, SD, USDC, ETH, BTC), and type-specific details.
receiver — the receiver's name and postal address, used for KYC and passed to delivery channels that require it.

❗️
Immutability
Once created, source, destination, and receiver are immutable. To change any of them, disable the FlowLink and create a new one.

Lifecycle status

Status	Behavior
`active`	Deposits are processed straight-through.
`paused`	Deposits are held until the FlowLink is resumed (or disabled).
`disabled`	Permanently deactivated; the address is decommissioned. A new FlowLink is required to resume use.

In this section

Creating a FlowLink — define source, destination, and receiver, and receive the deposit address.
Using a FlowLink — send deposits, manage the lifecycle (pause / resume / disable), and read transaction history.

Idempotency
FlowLink endpoints require an x-idempotency-key header (a UUID you generate), including the transactions read endpoint. Reuse the same key when retrying.
