Each links to the page with the detail. ### Security and wallets **Does Surge hold my funds or keys?** No. Your browser wallet's keys stay in the extension and your strategy wallets' keys stay encrypted in your browser. Surge only ever builds unsigned transactions; nothing moves without a signature from your browser. The one server-held key is Surge's own treasury for paying staking rewards. See [How non-custodial works](/getting-started/how-non-custodial-works.md). **Why does my strategy stop when I close the tab?** Because your browser is the only place the transaction can be signed. Grid and rule-based pause and resume automatically; arbitrage stops looking; DCA's timer stops; Cadence skips orders after 30 minutes. Keep the tab open and use Keep screen awake. See [How non-custodial works](/getting-started/how-non-custodial-works.md#why-your-strategy-stops-when-you-close-the-tab). **How do my wallets interact when I run arbitrage?** Sequential mode uses one strategy wallet (Wallet A) that buys, receives the tokens, sells them and receives the ADA. Parallel mode uses Wallet A (ADA, buys) and Wallet B (tokens, sells); each leg delivers to the *other* wallet so both stay stocked. Your browser wallet only funds them. See [Sequential arbitrage](/strategies/sequential-arbitrage.md) and [Parallel arbitrage](/strategies/parallel-arbitrage.md). ### Fees, orders, and rewards **What fees do I pay on a trade, and in what order?** In the order transaction: the Surge fee (0.2% of the ADA side, reduced by your tier), the DEX batcher fee (1–2.5 ADA), the refundable order deposit (2 ADA), and the network fee (\~0.2 ADA). The pool's \~0.3% fee is inside the exchange rate. The deposit comes back with the fill. See [Fee breakdown](/fees-tiers-and-staking/fee-breakdown.md). **How is the Surge fee calculated, and is there a minimum?** 0.2% of the ADA you spend (buy) or expect to receive (sell), times (1 − your tier discount). with a minimum of 0.978 ADA per order, so orders under about 489 ADA pay the flat minimum. See [The Surge fee and its minimum](/fees-tiers-and-staking/surge-fee-and-minimum.md). **How do tiers discount it?** Hold SURGE and subscribe to staking: 2,500 → 10%, 10,000 → 30%, 30,000 → 50%, 75,000 → 70%. The discount is applied to your rate at the next six-hourly snapshot. See [Tiers and discounts](/fees-tiers-and-staking/tiers-and-discounts.md). **How are staking rewards calculated and when are they paid?** Each five-day epoch, the Surge fees collected are multiplied by the staker share to form a pool; your share is your average snapshotted SURGE balance (scaled by how much of the epoch you were subscribed) over everyone's. Rewards are paid in ADA after you click Claim, in batches every two minutes, if your claim nets at least 0.978 ADA. See [Staking SURGE](/fees-tiers-and-staking/staking.md). **What happens if my order doesn't fill? Does it refund?** Minswap refunds automatically. SundaeSwap, WingRiders and Splash leave the order open until you cancel it; Surge's strategies offer you the cancel after 5 minutes, and manual swaps have a Cancel & reclaim button. Funds are never lost, only locked until you act. See [Cancelling stuck orders](/orders-and-transactions/cancelling-stuck-orders.md). **Why does an order take minutes to fill?** A DEX batcher, not the DEX contract, executes orders, and it needs a block or two. 1–2 minutes is normal; after 3 minutes Surge calls it stuck. See [How trading on Cardano DEXes works](/core-concepts/how-cardano-dex-trading-works.md). ### Strategies **How does the grid decide where to place orders, and what if the price leaves the range?** It divides your band into equal price steps; each rung buys at its lower line and sells at its upper. If the price leaves the band (plus your buffer) the grid pauses with "out of range"; it is re-evaluated when your tab reconnects to the strategy, so reload the strategy page once the price is back inside. See [Grid](/strategies/grid.md). **What does slippage / minimum received mean in Surge?** Every order carries an on-chain minimum you will accept, computed as expected output × (1 − your tolerance). If the pool cannot deliver it, the order refunds or parks rather than filling badly. Rule-based levels additionally use the level price itself as the floor. Arbitrage buys use a break-even floor instead of slippage. See [From decision to confirmation](/core-concepts/trade-lifecycle-and-statuses.md). **What's the difference between my browser wallet and a strategy wallet?** The browser wallet is your login and funding source and signs via the extension. Strategy wallets are created in your browser, hold only what you give them, and sign automated trades locally. See [Wallets in Surge](/core-concepts/wallets-in-surge.md). **What happens if I lose my browser or clear its data?** Strategy wallet keys live only in that browser and in your key-file backups. Import the backup into a new browser to recover; without it, the wallet is unrecoverable. Strategies, history and your account on Surge's servers are unaffected. **Is Automate signing safe?** Yes — it is on by default. It removes the approval prompt, not the transaction guard: a strategy can still only spend within its budget, only the tokens it declared, and only from its own wallet. Turn it off if you want to see and approve every trade while you get used to a strategy. See [Signing and approvals](/core-concepts/signing-and-approvals.md). **How is P\&L calculated, and what does it leave out?** From actual fills only, per completed round trip: ADA out minus ADA in minus Surge, batcher and network fees. Pool fees are inside the prices. Grid, Arbitrage and Rule-based feed the totals; Cadence shows a cash-flow figure on its own page only; DCA has no P\&L. Open positions are not counted. See [Profit and loss](/orders-and-transactions/pnl.md). **Which DEX should I use?** Minswap if you want unfillable orders refunded automatically. Among the DEXes you allow, a grid prices and trades on the deepest pool, a rule-based plan fires on whichever venue pays the most after fees, and arbitrage buys on the cheapest and sells on the dearest. See [Supported DEXes](/core-concepts/supported-dexes.md). **Can I run two strategies from one wallet?** Do not. Orders from one wallet must be two minutes apart, and two strategies sharing a wallet will collide or block each other. One strategy per wallet is enforced by the builders. **Can I edit a running strategy?** Some fields. Grid ranges, counts and investment are fixed; arbitrage mode and wallets are fixed; rule-based levels are fully editable. Clone (grid, DCA, arbitrage, cadence) to change fixed settings. See [Managing strategies](/strategies/managing-strategies.md). **Does pausing persist if I open Surge in another browser?** Only for Cadence. Grid, rule-based, arbitrage and DCA pauses are local to the browser that set them. See [Managing strategies](/strategies/managing-strategies.md#pause-and-resume--what-actually-persists). ### Prices and access **Where do prices come from?** From the DEX pools themselves, read from the chain by Surge's indexer every block, with outlier and liquidity filters. No third-party price feed. See [How prices are sourced](/core-concepts/how-prices-are-sourced.md). **Is there a mobile app?** No. Surge blocks screens narrower than 768 px. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.surgecardano.com/help/faq.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
