How to Choose Your Price Edge
Your price edge is the single most important setting as an ARM seller. It controls how much above or below the market rate you price your USDC. The protocol stores this as spreadBps, but the user-facing choice is easier to think about as a premium or discount versus market.
Understanding Premiums and Discounts
Your price edge is shown as a percentage relative to the market rate. You can adjust it from -5% to +5%.
| Price edge | What It Means | Trade-off |
|---|---|---|
| +0.5% | Slightly above market | Very competitive, fast fills, lower margin |
| +1% | 1% above market | Good balance of volume and profit |
| +2% | 2% above market | Higher margin, slower fills |
| +3% | 3% above market | High margin, may sit unfilled |
| 0% (Market rate) | Exactly at market | Maximum competitiveness, no price-edge profit |
| -0.5% | Below market | Aggressive pricing to attract volume |
Choosing the Right Price
There's no single correct price edge. It depends on the currency, competition, and your goals.
Major currencies (EUR, GBP, USD-adjacent pairs):
- These are high volume and competitive. Other sellers are pricing tightly.
- Typical range: +0.5% to +1%
Emerging market currencies (BRL, TRY, ZAR, IDR, PHP, MXN):
- Less competition, higher volatility, buyers expect to pay more.
- Typical range: +1% to +3%
Check the orderbook on the Trade page at app.peer.xyz to see what other sellers are charging — it shows exactly where your rate sits relative to other deposits.
Use the Orderbook
The deposit flow shows you the full orderbook so you can see exactly where your rate lands relative to other sellers. If you're way out to the right of everyone else, you're too expensive. If you're at the far left, you might be leaving money on the table.
Watch Your Fill Rate
- Orders filling instantly? You might be priced too low. Try increasing your premium slightly.
- Deposit sitting idle? Your premium may be too high. Reduce it or check the Trade page orderbook for competitive rates.
Different Prices for Different Currencies
You can add multiple currencies to a single deposit, each with its own price edge. Don't set the same premium across EUR, BRL, and JPY. Each market has different dynamics.
If the market moves sharply and your rate drops below your cost basis, consider setting a floor rate to protect yourself. See How to Set a Floor Rate.
