# Stablecoin Funding (On-Ramp & Off-Ramp)
## Move funds between fiat and stablecoin balances, automatically or on demand
Stablecoin Funding gives businesses a way to convert between their fiat and stablecoin Cobre Balances, keeping treasury operations flexible without leaving the Cobre platform. On-ramp converts fiat into stablecoins; off-ramp converts stablecoins back into fiat. Some conversions happen automatically as part of a payment flow, while others are triggered manually between a client's own accounts.
**This feature is enabled via API and Portal.**

## 1. What Cobre Enables with Stablecoin Funding
With Stablecoin Funding, Cobre enables businesses to:
* Convert **fiat USD to stablecoins (usd_stable)** and back, using their Global Cobre Balance
* Convert **fiat COP to COPco** and back, using their Colombian Cobre Balance
* Fund stablecoin payouts automatically, without a separate conversion step
* Move funds manually between their own fiat and stablecoin balances on demand
* Choose between standard (no cost) and instant (real-time) settlement when converting COPco back to COP
* Operate funding using the same conceptual primitives as other Cobre flows:
* Cobre Balances
* Money Movements
* Transactions

## 2. Stablecoin Funding in the Cobre Model
This capability fits into Cobre's ecosystem as the **bridge between fiat and stablecoin balances**:
* **Cobre Balance (Global fiat, USD)** and **Cobre Balance (Stable, usd_stable)** form the USD corridor
* **Cobre Balance (Colombia, COP)** and **Cobre Balance (Stable, COPco)** form the COP corridor
* **Money Movements** represent each conversion, whether triggered automatically as part of a payout/payin or manually between the client's own balances
* **Transactions** reflect the resulting debit and credit on each side of the conversion
In practical terms, Stablecoin Funding extends Cobre's balance model so fiat and stablecoin liquidity can move between each other using the same operational primitives used elsewhere on the platform.

## 3. Key Capabilities / Options
Stablecoin Funding is organized around two corridors and two modalities.
### 3.1 Corridors
* **USD corridor** — between the Global fiat Cobre Balance (USD) and the Stable Cobre Balance (usd_stable)
* **COP corridor** — between the Colombian fiat Cobre Balance (COP) and the Stable Cobre Balance (COPco)
### 3.2 Modalities
* **Automatic** — happens transparently as part of a payin or payout on the Global fiat balance. Only available on the **USD corridor**.
* **Manual** — the client explicitly transfers between their own balances. Available on **both corridors**.
### 3.3 Settlement Options for COPco Off-Ramp
When converting COPco back to COP fiat manually, two settlement options are available:
| Type | Credit Timing | Cost |
| --- | --- | --- |
| **Standard** | According to settlement windows | No cost |
| **Instant** | Real time | Has an associated cost |
### 3.4 On-Chain Behavior
The COP corridor involves on-chain operations at every step: on-ramp mints COPco, and off-ramp burns COPco, both through Cobre's underlying blockchain infrastructure. The credit on the receiving side only happens once the corresponding on-chain operation is confirmed. The USD corridor does not involve on-chain operations — it is a ledger-only conversion between the client's own balances.

## 4. Core Concepts and Terminology
* **On-Ramp**: Converting fiat balance into stablecoin balance
* **Off-Ramp**: Converting stablecoin balance back into fiat balance
* **Automatic On/Off-Ramp**: Conversion that happens transparently as part of a payin or payout, without a dedicated request (Cobre Balance Global)
* **Manual On/Off-Ramp**: A conversion explicitly requested by the client between two of their own Cobre Balances (Cobre Balance Stable)
* **Settlement type**: For COPco off-ramp, whether the resulting COP credit is standard (scheduled, free) or instant (real-time, has a cost)
* **Mint / Burn**: The on-chain issuance or destruction of COPco that backs each COP corridor conversion
---
## 5. Speed, Settlement & Reliability
* **USD corridor**: manual conversions are ledger-only and settle immediately between the client's own balances; automatic conversions happen inline with the payin or payout they support.
* **COP corridor**: conversions depend on an on-chain mint or burn confirming before the opposite side is credited. For off-ramp, standard settlement credits COP according to defined windows; instant settlement credits COP in real time for an added cost.
If an on-chain mint or burn fails, the originating debit is automatically reversed and no conversion is applied.
---
## 6. Typical Business Use Cases
* Businesses that **hold working capital in stablecoins** but need to pay local obligations in fiat
* Platforms that **collect in fiat and disburse in stablecoins** (or vice versa) as part of their payment flow
* Treasury teams that want to **shift liquidity between fiat and stablecoin balances** based on market conditions or operational needs
* Colombian businesses building a **COPco savings position** while retaining the ability to convert back to COP on demand
This capability fits best when businesses need **flexible, on-demand conversion** between the fiat and stablecoin liquidity they already hold on Cobre.
---
## 7. Transactions, Reporting & Reconciliation
Every on-ramp or off-ramp produces a pair of transactions — a debit on the source balance and a credit on the destination balance — that can be reconciled against each other using the originating Money Movement:
* Manual conversions generate transactions traceable back to the client's own Money Movement id
* Automatic conversions are embedded in the payin/payout transaction flow they support
* COP corridor conversions additionally carry on-chain confirmation as part of their lifecycle, giving finance teams an extra verification point
This provides consistent, auditable tracking of every fiat-to-stablecoin movement across both corridors.
---
## 8. Governance, Controls & Auditability
Stablecoin Funding includes the following controls:
* **Corridor and modality restrictions**: automatic conversion is only available on the USD corridor; the COP corridor is manual-only
* **On-chain confirmation gating**: COP corridor credits only occur after the underlying mint or burn is confirmed, with automatic reversal on failure
* **Settlement type selection**: businesses explicitly choose standard or instant settlement for COPco off-ramp, with cost implications made clear at request time
This provides a foundation for predictable, controlled conversion behavior across both corridors.

## 9. Stablecoin Funding vs StableFX
| Dimension | Stablecoin Funding (On/Off-Ramp) | StableFX |
| --- | --- | --- |
| What it converts | Fiat ↔ stablecoin/COPco (same market, e.g. USD ↔ usd_stable, COP ↔ copco) | usd_stable ↔ copco |
| Corridors | USD and COP | usd_stable/copco only |
| Pricing | No FX rate involved (1:1 within the same currency) | Uses an FX quote and rate |
| Typical use | Moving liquidity between fiat and stablecoin balances | Converting between two different stablecoin denominations |

## 10. Summary — What Cobre Delivers with Stablecoin Funding
Cobre enables businesses to:
Convert between **fiat USD and usd_stable** on demand or automatically
Convert between **fiat COP and COPco** on demand, with standard or instant settlement
Fund stablecoin payouts automatically without a separate conversion step
Rely on automatic reversal if an on-chain mint or burn fails
Standardize conversions using Cobre's familiar model: balances → money movements → transactions
Stablecoin Funding gives businesses the flexibility to move liquidity between fiat and stablecoin balances whenever their operations require it, with the controls and traceability expected from a payments platform.
