Concepts
Single-sided deposits.
Deposit only ETH or only USDG and get a ladder of buy orders below the price.
Most people hold one side of a pair. Obol lets you deposit only ETH, WETH or USDG (or only the token), and builds the part of the ladder that token can fill.
Which bins get funded
| Bin position | Holds | Funded by |
|---|---|---|
| Entirely below the current price | The quote token (ETH / USDG) | Quote deposits |
| Entirely above the current price | The token | Token deposits |
| Containing the current price | Both | Only when you deposit both tokens |
With a quote-only deposit, the bin that contains the current price is skipped (it would need the token too), and your deposit is spread over the bins below the price according to the shape. Nothing is wasted: anything that cannot be placed is refunded in the same transaction.

What it means for you
- No fees until the price moves into your bins. The ladder is “in range” as soon as the price is between min and max, but it only earns when trades cross a funded bin.
- You end up holding what you asked to buy. A quote-only ladder that gets crossed turns into the token.
- Native ETH on V4. On V4 pools paired with native ETH you send ETH directly; no wrapping, no approval.
The part of your range above the price stays empty with a quote-only deposit. On the ladder page these bins show as “empty” so you can see exactly where your capital is.
