# Overview

> Standing infrastructure that automatically converts value every time it arrives, instead of a one-off call per transfer.

Orchestration resources are persistent infrastructure - a bank account or an on-chain address you set up once - that automatically convert currency every time value arrives at them. Unlike [Onramps](/v3/core/transactions/onramps) and [Offramps](/v3/core/transactions/offramps), which convert one specific amount you request, an Orchestration resource sits there indefinitely and reacts to deposits as they show up.

## Resources

* [**Virtual Accounts**](/v3/core/orchestration/virtual-accounts) - a persistent USD deposit account. Every deposit a user sends to it automatically mints stablecoins to a wallet - no quote or accept step.
* [**Orchestration Address**](/v3/core/orchestration/orchestration-address) - a persistent on-chain address. Every stablecoin deposit it receives is automatically off-ramped to a bank account - immediately, on a schedule, or once a balance threshold is met.

| Direction                      | Fiat → stablecoin                                       | Stablecoin → fiat                                                         |
| Deposit                        | User sends USD via ACH, Wire, or RTP                    | User sends USDC/USDT on-chain                                             |
| Destination                    | A HIFI Wallet or External Wallet                        | An External Account                                                       |
| Underlying transaction created | One [Onramp](/v3/core/transactions/onramps) per deposit | One [Offramp](/v3/core/transactions/offramps) per batch                   |
| Timing                         | Immediate, per deposit                                  | Configurable - per deposit, on a schedule, or once a threshold is reached |

Both are **set up once, then forgotten**: create the resource, share the resulting deposit instructions or address with whoever is sending funds, and HIFI handles the conversion every time value shows up - with no further API calls required per deposit.

## Common Conventions

* **No quote step**: unlike Onramp, Offramp, Swap, and Bridge, neither resource is created through a quote-then-accept flow. Deposits convert at the live rate when they're detected.
* **Idempotency**: creating either resource takes a client-supplied `requestId` (UUID) or an `Idempotency-Key` header. Reusing the same key with the same payload returns the existing record instead of creating a duplicate; reusing it with a different payload is rejected with `RESOURCE_CONFLICT` (409).
* **Underlying transactions**: every deposit still produces a normal Onramp or Offramp transaction under the hood. Tracking a specific conversion works the same way you'd track any other transaction - `GET` it directly, or subscribe to its webhooks.

## Transaction Monitoring

Every transaction an Orchestration resource produces goes through the same compliance monitoring as any directly-created Onramp or Offramp. While a produced transaction is being reviewed, its `status` remains `IN_REVIEW` until compliance clears it. If HIFI's compliance team needs more information to clear it, we will send a Request for Information (RFI).
