This page is kept as a record for anyone still settling funds from that era. {% endhint %} ## I'm getting an insufficient lampports error. You must have at least 0.03SOL in your wallet for transaction fees. ## Why do I need to have at least 0.03SOL? For the first transaction, **≈0.024 SOL** is required (creating a transaction wallet), so Serum Orderbook requires a minimum holding of 0.03 SOL.\ In order to trade, you will need to deposit some SOL to your wallet.\ Due to Serum's design, there is need to open a trading account for the pair when you first trade it.\ So, the “first trade” fee is ≈0.024 SOL ## Sometimes my balance wont show up? Sometimes, there are delays with the Solana RPC ( Serum Orderbook ). Please wait a moment on the balance screen. The balances page that used to answer this, at `trade.dexlab.space`, has been retired. Your token balances are now on . ## I can't see my order history. Solana RPC response is delayed, and some order histories take time to load. Please wait at least 1 minute on the screen. The open orders page that used to answer this, at `trade.dexlab.space`, has been retired along with the order book itself, so there is no order history to load there any more. ## I completed the transaction, but the tokens did not arrive in my wallet. All transactions are deposited into the transaction wallet you connected with. Please settle your funds through the transaction screen or the Balances page. If this does not work, you can also check under the market you transacted, and settle your funds there. ## The order was not created due to a program error. If your order cannot be placed due to a connection problem with Solana RPC, please wait at least 1 minute on this page. If there are too many requests (more than 30 requests per 10 seconds), RPC will generate a response error (429). ## Where can I trade Dexlab ($DXL) tokens? Currently, DXL tokens can be traded below.\ Dexlab:\ \ \ Raydium:\ \ \ Coingecko:\ \ \ Coinmarketcap:\ ## **Why can't am I seeing a transaction error when settling on the DEX?** If you're receiving a transaction error when settling, for example, your transaction logs say something like *Program 9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin failed: custom program error: 0x1000772*, then check the Referrer Quote Wallet in the explorer. If should be an SPL token account for the quote currency. If it is not, e.g., it's a SOL address, then the GUI you're using is invalid, and you should switch to a new one. ## **Why am I getting System program error 1 when trading on the DEX?** `System program error 1` indicates a lack of SOL in the wallet to complete the transaction. You may need as much as `0.03-0.1SOL` to conduct a trade. ## **How do I delete a duplicate token account (not a mnemonic)?** TFirst, this happens due to an oversight in some applications. They should be using associated token accounts. Now, before deleting your account, know that this is very dangerous. If you ever send to the deleted address, you might lose your funds! This used to be done in the Sollet wallet, by enabling a hidden setting from the browser developer console. Both sollet.io and the DexLab Sollet fork have now been retired, so that route is no longer available. Use a maintained Solana wallet that offers a close account or burn function instead. The procedure is the same wherever you do it. Open up the token details of the token you want to remove. Send all the tokens of that single token type, for example, USDC, to a new wallet that you control (so that your token balances of the token you want to delete are zero). Then a Delete button will appear. Stop. Ask yourself if this is what you really want to do. If yes, then delete. It is strongly recommended to transfer all tokens to a new wallet after deleting an address. Again, if you ever send to a deleted address, you will incinerate your funds. Be careful. ## Why is the current price different from the price on the chart? The chart is displayed based on the transaction history. The last price shown on the chart is the last traded price. The current price will depend on the OrderBook even if there are no trades executed at the calculated price according to buy/sell (all Serum DEX are the same) *Chart = based on the transaction history we are collecting*\ *Price = Calculated price according to Buy/Sell volume of Serum DEX* --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.dexlab.space/products/getting-started/dexlab-dex/dexlab-trading-faqs.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
