First steps {% hint style="info" %} Prerequisites : * Windows operating system (your computer or a [VPS](https://en.wikipedia.org/wiki/Virtual_private_server), have a look at the FAQ) {% endhint %} ## 2. Configure your settings You need first to configure your account. 1\. **Run the ChainSniper PumpBot first**, and enter your wallet and Private Key, or add them into the .json file. 2\. Open **settings.json** file and set your Exchange / Node values: ``` [ { "WALLETADDRESS": "0x68d8Bfa07451dBa40ec61FdB6b431e04C99368DE", "PRIVATEKEY": "083d1908f5b162cf94c651e85a5d61223b85c645aa944796dbcdf28df720033f", "WALLETADDRESS2": "null", "PRIVATEKEY2": "null", "WALLETADDRESS3": "null", "PRIVATEKEY3": "null", "WALLETADDRESS4": "null", "PRIVATEKEY4": "null", "WALLETADDRESS5": "null", "PRIVATEKEY5": "null", "MEMPOOL_METHOD": "public_node", "USECUSTOMNODE": "false", "CUSTOMNODE": "false", "EXCHANGE": "pancakeswap", "EXCHANGEVERSION": "2", "PREAPPROVE": "true", "UNLIMITEDSLIPPAGE": "false", "VERBOSE_PRICING": "true", "SLOW_MODE": "false", "START_BUY_AFTER_TIMESTAMP": "not used", "START_SELL_AFTER_TIMESTAMP": "not used", "_EXCHANGE_BASE_SYMBOL": "BNB ", "_STABLE_BASES": { "USDT": { "address": "0x55d398326f99059ff775485246999027b3197955", "multiplier": 0 }, "BUSD": { "address": "0xe9e7cea3dedca5984780bafc599bd69add087d56", "multiplier": 0 }, "USDC": { "address": "0x8ac76a51cc950d9822d68b83fe1ad97b32cd580d", "multiplier": 0 } }, "ENCRYPTPRIVATEKEYS": "false" } ] ``` {% hint style="success" %} Chainsniper can trade with 5 wallets at the same time, if you use MULTIPLEBUYS option {% endhint %} * **EXCHANGE** : enter the exchange you want to use.

Select "1" or "2". If you're not using Pancake, just leave it like this, bot won't take it into account.\
* **PRIVATEKEY** \ You need to enter here the **Private key (and not the 12 words seed phrase)** of the wallets you want to use. [Read this article](https://metamask.zendesk.com/hc/en-us/articles/360015289632-How-to-Export-an-Account-Private-Key) to learn how to export your private key from Metamask. {% hint style="info" %} You can use **same wallet or different wallets.** It's as you prefer. {% endhint %} * **USECUSTOMNODE** \ Set it to "true" if you want to use a custom node.\
* **CUSTOMNODE** \ If you want to use a custom node, enter here your node's address **in http, wss, or IPC**\ Example: wss\://bsc-ws-node.nariox.org:443 * **PREAPPROVE** \ Tells the bot to preapprove tokens on startup or not
* **ENCRYPTPRIVATEKEYS** \ Will be filled automatically when you start the bot for the first time\
* **UNLIMITEDSLIPPAGE** \ Use this parameter if you want the bot to bypass completely the slippage setting and buy at any slippage, to avoid the "INSUFFICIENT\_AMOUNT" Error \ \ If you select UNLIMITEDSLIPPAGE= true, bot won't take into account SLIPPAGE parameter. {% hint style="danger" %} **Use UNLIMITED SLIPPAGE WITH CAUTION** \ THIS SHOULD BE USED FOR DEGEN SNIPES ONLY AND CAN RESULT IN LOSS OF FUNDS IF USED INCORRECTLY!!! {% endhint %} * **VERBOSE\_PRICING**\ Default setting is "true", but if you set it to "false", bot will only show lines on the screen if the price is updated, like this : ![](/files/HYLXfAWtwe632h0LoUY7) * **SLOW\_MODE** A user contacted me because he was running the bot 24/7 on the default node, and his IP got temporarily banned because he made too many calls.\ Indeed, on default RPC nodes, there is a rate limit (example : )\ \--> We created a SLOW\_MODE parameter, who **makes the bot do price check every 0.5s only**.\ Use it if you let the bot run all night on default node, if you just need to sell tokens without need for sniping, for instance To use it : * enter `SLOW_MODE : true` in settings.json ## 3/ Configure your tokens Open **tokens.json** to configure the tokens and the orders that your bot will create. Here's an example: ``` [ { "ENABLED": "true", "SYMBOL": "CAKE", "ADDRESS": "0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82", // ----------- BUY / SELL PARAMETERS ---------------------------------------------------------------------------------------- "KIND_OF_SWAP": "base", // enter "base" to use BUYAMOUNTINBASE , and "tokens" to use BUYAMOUNTINTOKENS "BUYAMOUNTINBASE": "0.000001", "BUYAMOUNTINTOKEN": "5", "MAX_BASE_AMOUNT_PER_EXACT_TOKENS_TRANSACTION": "0.5", // used with KIND_OF_SWAP = tokens "BUYPRICEINBASE": "0", "SELLPRICEINBASE": "200%", // You can now put amount in % in this field "SELLAMOUNTINTOKENS": "ALL", "STOPLOSSPRICEINBASE": "60%", // You can now put amount in % in this field "TRAILING_STOP_LOSS": "40%", // put amount in % in this field.

* **SYMBOL**\ Symbol of the token you want to buy\
* **ADDRESS**\ Contract address of the token you want to buy
* **KIND\_OF\_SWAP**\ You now have the choice between : \ 1/ **"KIND\_OF\_SWAP": "base"** --> you want to swap with an amount of Base tokens\ (example : I want to buy 1 BNB of CAKE token)\ \ 2/ **"KIND\_OF\_SWAP": "tokens"** --> you want to swap an exact amount of tokens\ (example : I want to buy 50 CAKE tokens)\
* **BUYAMOUNTINBASE** (used with "KIND\_OF\_SWAP": "**base**")\ Put here the amount **in the base symbol** that you want the bot to buy with\
* **BUYAMOUNTINTOKEN** (used with "KIND\_OF\_SWAP": "**tokens**")\ Put here the **amount** **of tokens** that you want the bot to buy \
* **MAX\_BASE\_AMOUNT\_PER\_EXACT\_TOKENS\_TRANSACTION**\ (used with "KIND\_OF\_SWAP": "**tokens**")\ Put here the maximum amount of BNB / ETH / AVAX... that you want the bot to use, if you're swapping per tokens\ \--> this option avoids you to spend too much to buy the tokens you want to buy\
* **BUYPRICEINBASE** (used with "KIND\_OF\_SWAP": "**base**")\ Buy price of 1 token **in the base symbol** : if the price of 1 token is < or = to this price, the bot will buy. {% hint style="info" %} **If you want the bot to never buy, set BUYPRICEINBASE = 0** \ (price cannot be below 0) {% endhint %} * **SELLPRICEINBASE**\ Sell price of 1 token **in the base symbol** : if the price of 1 token is > or = to this price, the bot will sell.\ (it will sell at the Market price, not at your price)\ \ **NEW : you can now enter a sell price in %**\ Chainsniper is now able to determine the SELL price according to your real BUY price You just need to enter an amount in % in SELLPRICEINBASE and STOPLOSSPRICEINBASE, and it will automatically calculate sell price.
**Example :** "SELLPRICEINBASE": "300%" "STOPLOSSPRICEINBASE": "60%" {% hint style="warning" %} BUYPRICEINBASE and SELLPRICEINBASE are the buy price of **ONE token in BASE** **pair**. Think about it as if you were in front of this screen: {% endhint %} ![](/files/jKkwnpaUKYaNrJPuRTez) {% hint style="info" %} **If you want the bot to never sell, set SELLPRICEINBASE = 99999999** {% endhint %} * **STOPLOSSPRICEINBASE**\ Set your Stop Loss price **in the base symbol** \ Bot will sell if token price < STOPLOSS price
* **TRAILING\_STOP\_LOSS**\ A trailing stop-loss is an **intelligent version of a normal stop-loss**, which is a limit sell that fills if the price dips below a certain point, preventing losses from happening.
In a trailing stop-loss, the sell price follows (or “trails”) behind the current price of your chosen token, meaning that if the price moons and then unexpectedly drops, then the stop-loss would trigger at a higher price, meaning more profits for you.\ \ `How to use it :`\ "TRAILING\_STOP\_LOSS": "80%" means that bot will sell if price goes down to 80% of ATH price (--> if ATH was 2$, bot will sell at 1.60$) \
* **SLIPPAGE** \ Slippage you want to use (in %).\
* **MOONBAG**\ Minimal amount of token you want to keep in your wallet. If you don't want to keep any token, put 0.\ \&#xNAN;*(in this example, the bot will keep at least 20 KPAD token in your wallet)*\
* **MAXTOKENS** \ This parameter is used to **make the bot stop buying**: * before buying, the bot checks MAXTOKENS * if you hold more tokens than MAXTOKENS, the bot does not buy {% hint style="info" %} This parameter **does not** **influence how many tokens the bot will buy** during your trade: if you set MAXTOKENS = 1, the bot can buy 50000 tokens for example, no problem {% endhint %} If you want to make the bot stop buying after 1 trade, set MAXTOKENS to a low value, like "1" for instance.
* **RUGDOC\_CHECK** \ Call RugDoc's API to check if a contract is a honeypot or not. Check their website, be careful it cannot be 100% reliable of course! ### Anti-antibot parameters * BUYAFTER\_XXX\_SECONDS * WAIT\_FOR\_OPEN\_TRADE * START\_BUY\_AFTER\_TIMESTAMP\ START\_SELL\_AFTER\_TIMESTAMP * MULTIPLEBUYS * BUYCOUNT [Please read dedicated "Counter anti-bot measures" page
](broken://pages/0GHwxx2ZP5ljH6ABGiAu) ### Liquidity parameters * LIQUIDITYINNATIVETOKEN * USECUSTOMBASEPAIR * BASESYMBOL * BASEADDRESS * WATCH\_STABLES\_PAIRS
:warning: :warning::warning: [Please read dedicated page carefully](broken://pages/hrhc9N0t8ufev6rwoquh) :warning::warning::warning: {% hint style="danger" %} **WARNING : be VERY CAREFUL about those liquidity** **options**\ If you set up wrong configuration, bot will trade on wrong pair and make you lose funds. Beware {% endhint %} ### Pinksale parameters * PINKSALE\_PRESALE\_ADDRESS * PINKSALE\_PRESALE\_START\_TIMESTAMP * "WAIT\_FOR\_OPEN\_TRADE": "pinksale" [Please read dedicated "Snipe Pinksale launches" page
](broken://pages/8XNrW4Di4186q3BWonjE) * **MAX\_FAILED\_TRANSACTIONS\_IN\_A\_ROW** \ Tells the bot to stop making buy/sell orders after XXX failed transactions\
* **MAX\_SUCCESS\_TRANSACTIONS\_IN\_A\_ROW** \ Tells the bot to stop making buy/sell orders after XXX success transactions\ \ `Example :` if you want the bot to make 1 BUY and 1 SELL Tx, set it to **2**\
* **ALWAYS\_CHECK\_BALANCE**\ To increase speed to maximum, the default behaviour of Chainsniper is to check your balance only at bot launch. It allows to reduce the amount of actions before make a sell order.\ But some users want the bot to detect when they receive a token in their wallet while the bot is running, to sell the tokens as quickly as possible\ \--> use this option to **make the bot check your tokens balance between every price check** (but this makes the bot a little bit slower - not too much slower, don't worry)\
* **MINIMUM\_LIQUIDITY\_IN\_DOLLARS** (since 4.0.5)\ Use this option if you want the bot to set a **minimal** **amount of liquidity** before buying. Put liquidity amount in $. {% hint style="danger" %} Some people add very small amount of liquidity to Exchanges --> if you swap on this, you will lose all your money !!\ \ To avoid this, the team recommend to set **MINIMUM\_LIQUIDITY\_IN\_DOLLARS = 10000** {% endhint %} * **SELLAMOUNTINTOKENS**\ Put here the **amount** **of token** that you want the bot to sell \
* **HASFEES** \ Select "TRUE" if you want to trade a token with additional fees, like automatic transfer to liquidity when you buy / additional taxes / rebase / etc.\ \ If you don't use this on such tokens, you may have a Tx failed with "Pancake:K" error\
* **GAS / BOOSTPERCENT** There is 2 ways to set your Gas : 1. **Set your** **own fixed Gas price** --> simply set Gas price in "GAS" parameter ``` "GAS": "200", ``` 2. **Let the bot calculate Gas price** relating to current Gas Price on blockchain : 1. it reads the gas price on the blockchain 2. it applies the boost you set on Fast price. Example : ``` "GAS": "BOOST", "BOOSTPERCENT": "30", ``` * **MAX\_GAS** \ Put here the maximum of GAS you want to pay if you use BOOST. \ If GAS > MAX\_GAS : Tx won't be made\
* **GASLIMIT** \ Set it with the Gaslimit value you want to use \ (we recommend to set it to **1000000** to avoid to be out of Gas)\
* **GASPRIORITY\_FOR\_ETH\_ONLY**\ This is for ETH and AVAX only : sets Max Priority Gas.\ The max priority fee, also referred to as the "**miner tip**", goes to the miner or validator, and incentivizes them to prioritize your transaction. Most often, the value you put in for "max priority fee" will be the amount you pay. \ More details here : ![](/files/wZ4AjsNE4WewZRy6cEE4) ## 4/ Launch the bot :rocket: * Start making Money on DEX Exchanges! * Enjoy your Lambo :race\_car:
