# Exchanges

> Generate yield on idle exchange balances

> Generate yield on idle exchange balances

Exchanges hold significant stablecoin reserves that sit idle — user deposits awaiting trades, settlement float, treasury reserves, and order book liquidity buffers. RebelFi turns these idle balances into a revenue stream.

## Supported Blockchains

| Blockchain | Token Support | Status      |
| ---------- | ------------- | ----------- |
| Solana     | USDC, USDT    | Live        |
| Polygon    | USDC, USDT    | Live        |
| Ethereum   | USDC, USDT    | Live        |
| Base       | USDC          | Live        |
| Arbitrum   | USDC, USDT    | Coming Soon |

## The Opportunity

### Where Idle Capital Sits

* **User deposit accounts** — Stablecoins deposited but not actively trading
* **Settlement float** — Funds between trade execution and withdrawal
* **Treasury reserves** — Operating capital and reserves
* **Order book buffers** — Liquidity reserves for market making

### Example Economics

```
Exchange stablecoin holdings: $50M
Deployable (conservative, 60%): $30M
Annual yield (5-8% APY): $1.5M - $2.4M
Previous yield on these balances: $0
```

<Note>
  Yield rates are variable and depend on market conditions. The figures above are illustrative.

## How It Works

1. Register your exchange wallets with RebelFi
2. Call the supply API with the amount you want to deploy → receive unsigned transaction(s)
3. Sign with your custody solution and submit
4. RebelFi tracks allocations, accrues yield, and provides reporting
5. Unwind anytime — funds typically available in 30-60 seconds (Solana) or 1-3 minutes (EVM)

## Revenue Models

### Treasury Yield

Deploy exchange reserves to earn yield directly.

### User Deposit Yield

Offer yield to users as a competitive feature:

* Earn 5-8% gross → pay users 3-5% → keep the spread
* Differentiates your exchange from competitors

### Example Economics

```
Exchange stablecoin holdings: $50M
Deployable (conservative, 60%): $30M
Annual yield (5-8% APY): $1.5M - $2.4M

User deposit yield model:
  Gross yield: $2M
  Paid to users (4% APY): $1.2M
  Exchange revenue (spread): $800k
```
