Quote assets
What a coin can be paired with, and what that means.
The quote asset is the asset a coin is priced in, raised in and pays fees in. It is chosen at launch and can never change. The list is a whitelist managed by the protocol; it currently includes:
| Asset | Kind | Notes |
|---|---|---|
| wNVDAx, wTSLAx, wAAPLx, wGOOGLx, wMETAx, wSPYx, wQQQx, wSPCXx | Tokenized stocks / ETFs | Wrapped xStocks by Backed (ERC-4626). The wrapper is used, never the raw rebasing xStock. |
| WETH | Ether | Wrapped ETH on Ink. |
| kBTC | Bitcoin | Kraken wrapped Bitcoin, 8 decimals. |
| XAUt0 | Gold | Tether Gold on Ink. |
| USDT0, USDC, USDG | Stablecoins | 6 decimals. |
Why wrapped xStocks
Raw xStocks rebase (their balance changes by itself), which breaks constant-product math. The wrapped versions are standard ERC-4626 vaults with a stable balance and a growing exchange rate. The app lets you wrap and unwrap from the token page.
Paying with ETH or USDT0
You do not need to hold the quote asset. The swap box can take ETH or USDT0 and route them through Ink's DEX liquidity into the quote asset in the same transaction (the “zap”). The route, the resulting price impact and the minimum received are shown before you sign.
