Set the amount once, then act fast when you spot a coin. You stay non-custodial β€” every trade is still signed by your wallet (or your popup-free Novamp trading wallet on Solana). {% endhint %} ## Overview Quick Buy & Sell is the fast path. Instead of opening the full swap panel, you pre-set a spend amount (in the chain's native asset) and execute in one tap from: * a **Discover** or **Trenches** feed row (the ⚑ **Instant buy** button), * your **Watchlist**, or * the **token detail page** trade panel. The spend asset follows the coin's chain automatically: ETH on `🟒 Robinhood Chain` / `πŸ”΅ Base` / `βšͺ Ethereum`, BNB on `🟑 BNB Chain`, HYPE on `🟣 HyperEVM`, and SOL on `πŸŸͺ Solana`. ## How it works ```mermaid flowchart LR A[Set quick-buy amount] --> B[Tap Instant buy on a coin] B --> C{Chain} C -->|Solana| D[Novamp trading wallet signs β€” no popup] C -->|EVM| E[Wallet signs via integrated router] D --> F[Confirmation + balance update] E --> F ``` * **EVM (RHC / Base / ETH / BNB / HyperEVM):** one-tap buys route through the integrated aggregator and your wallet signs. Unsupported cases open the token desk with your amount pre-filled. * **HyperEVM:** Instant follows the exact same path as [Swap](/traders/swap.md) β€” a direct HyperSwap route preferred over 0x β€” spending native **HYPE**. * **Solana:** buys/sells execute from your **Novamp trading wallet** (a non-custodial embedded wallet secured by Privy). Trades are signed in a secure enclave with **no wallet popup** and routed by Jupiter. ## How to use it **Set your amount** * Use the **⚑ Quick buy** control in any feed toolbar. Pick a preset chip or type a custom amount. The value is remembered per device. * On Solana you can edit your **⚑ Instant buy** SOL presets and **⚑ Instant sell** percentage presets directly in the trade panel. **Buy** * Tap **Instant buy** on a row, or a preset in the token panel. On EVM your wallet asks you to confirm; on Solana it executes instantly after a one-time acknowledgement. **Sell** * On the token page, switch to **Sell** and tap a percentage (25% / 50% / 75% / MAX). Partial quick-sells stay one-tap after the first acknowledgement. ## Important details | Detail | Behavior | | ------------------ | ------------------------------------------------------------------------ | | Spend asset | Follows the coin's chain (ETH / BNB / SOL) | | Solana signing | Popup-free via Novamp trading wallet (Privy enclave) | | Solana routing fee | **0.5%** Novamp routing fee, shown in the quote (Jupiter) | | Large-buy guard | A buy of **β‰₯ 5 SOL** needs a second confirming tap | | MAX sell guard | Selling **100%** always requires a second explicit tap | | Confirm window | An armed one-tap confirm stays live \~4 seconds, then reverts | | First-time ack | A one-time "1-click trading is on" acknowledgement before instant trades | {% hint style="warning" %} One-tap trading is fast by design. Double-check the coin, chain, and amount before you tap β€” an instant buy executes immediately, and newly launched coins are high risk. See [⚠️ Trading Risks](/traders/trading-risks.md). {% endhint %} ## What happens next? 1. The trade is signed and submitted (instantly on Solana, after wallet confirmation on EVM). 2. A toast confirms the fill; on Solana you get a **View on Solscan** link. 3. Your balance updates optimistically and the position lands in your [Portfolio](/portfolio-and-analytics/portfolio.md). ## Troubleshooting | Symptom | Likely cause | What to do | | --------------------------------- | -------------------------------- | ------------------------------------------------------ | | "Your trading wallet has no SOL" | Solana trading wallet unfunded | Tap **Deposit** and send SOL to your trading wallet | | Nothing happens on first tap | One-tap confirm is arming | Tap again within a few seconds to execute | | "Setting up your trading wallet…" | Solana wallet still initializing | Wait a few seconds and retry | | Buy opened the token page instead | Chain not supported for one-tap | Trade from the token panel with your amount pre-filled | | EVM buy needs a network switch | Wallet on the wrong chain | Approve the switch, then confirm | ## Continue exploring * [πŸ”„ Swap](/traders/swap.md) * [πŸ“Š Token Detail Pages](/traders/token-detail.md) * [πŸ“‰ Slippage & Price Impact](/traders/slippage-and-price-impact.md) * [⚠️ Trading Risks](/traders/trading-risks.md) --- # Agent Instructions This documentation is published with GitBook.
