Buy Configuration Settings

Slippage

Slippage is the difference between the expected price of an order and the price when the order actually executes. By default set to 100% means you accept any amount of token. For new launches, it is common to have 100% slippage, but you can change it to suit your risk profile.

On zero-tax token launches without using AntiMev you might want to reduce the slippage. Its a trade off between successful execution and risk limitations.

GasLimit

'Gas limit' is the maximum amount of work you're estimating a validator will do on a particular transaction. By default set 521k, but you can set it as you would like. Do not set it too low, as the transaction will not be processed and the transaction will fail.

Manual Gas

Use manual gas if you want to personalize your gas settings. In case you want to use auto set to autogas settings. Set the Manual Gas setting descriptions below:

Gas %

Using the gas multiplier, eg add 10% on top of the current average block gas, you can increase the actual gas price value you want to pay to process your swap transaction with an added percentage amount.

Uniswap Router

The trader can specify which liquidity pool they wish to transact, beyond the standard Uniswap V2 pool. For LIVE tokens you have the option to select V3 pool here if the deployer has used it. Select V3 pool here and the Pool fee used in the box to the right. You do not have to make any changes from the default if you are setting to buy prelaunch, Readyswap will select the correct pool.

Uniswap V3 Fee

Select the corresponding Uniswap V3 pool by its fee structure. 0.05%, 0.3% or 1%

As an example, if you search for your token on Dexscreener or Dextools you will see what pools are available.

For example, PEPE token has 3 different pools available, Uniswap V2, Uniswap V3 0.3% and Uniswap V3 1%.

Delay Type

You can set delay sending your swap transaction, but block delay or millisecond delay. In case you want to skip particular blocks or set some time to delay your transaction use it accordingly.

You might want to delay your entry block if, for example, the first 3 blocks of the token contract you wish to enter have a very high buy tax.

Delay Value

If you are using block delay set the number of blocks you want to skip. Eg:1,2,3 If you are using block ms, set the number of milliseconds you want to delay your transaction.

Dynamic Nonce

Each transaction's nonce is an identifier that ensures your transactions are processed by the network in the correct order. Enable Dynamic Nonce if you performing more than one trade from one wallet at one time. This avoids the 'Nonce too low' error message.

Auto Approve

AutosApprove automatically sends an approval transaction immediately when sending a buy swap transaction.

The Auto-approval transaction is only sent after a successful Buy swap transaction. Some swap services process auto-approvals costing $5-10+ a time, even if the buy swap transaction has failed and been reverted.

AntiMEV

Enabling Anti-Mev changes the node used from a shared private node to a public AntiMev node, sacrificing speed and reliability, but avoiding the risk of being front-run by MevBot sandwich bots. Typical Mevbots are attractive to zero-tax token launches.

Anti Revert

A unique Readyswap feature. When you set a Token Amount to buy, for instance a Max Buy of 1% or 2% of supply with an associated Max Eth amount, and the price moves beyond your Max Eth / Max Buy amount, then your transaction fails and reverts. Frustrating!

Anti-Revert combats this issue by sending two transactions. Your Max buy % with Max Eth AND a transaction with only your Max Eth, allowing you to buy max amount available with your slippage settings even if below your amount.

If the MaxBuy% swap is successful, then great!, but if it fails the backup swap gives the trader a second opportunity to swap for tokens early. If 1st transaction succeeds the 2nd will auto-revert. You will incur a failed swap reversion cost of a few dollars depending upon gas, for reverted and failed transactions. Something for nothing doesn't happen on the blockchain!

Dev Scan

The following function enable just those methods which are called by the token deployer address not just any address. This is great when you want to avoid others interacting with the contract to create wrong pool or other users adding fake methods.

Buy Settings: Manual Gas

Enabling Manual Gas initiates three new parameters. Descriptions are below:

GasPrice

General reference for approximate transaction fees. By default, the bot runs with a Gas multiplier so it`s always using the estimated gas of the current block.

By switching to manual gas price you set your gas here, without the multiplier.

Set Manual gas price either higher or lower, compared to current block gas. Low gas risks slow, or failed transactions. Very high gas generates the fastest transaction, useful for quick entries into hyped tokens, but with higher cost.

MaxFeePerGas

Maxfeepergas EIP-1559 Transaction. This represents the maximum amount of gas fee a user is willing to pay for a transaction. Set the maximum you are willing to spend for the transaction. With that, you leave room for your gas settings in case the gas spikes suddenly.

MasPriorityFeePerGas

MaxpriorityFeePerGas Miners can be compensated for the computational work by receiving a 'tip'. When you submit a transaction you will also provide this 'tip' in the maxPriorityFeePerGas field. Gas price is the primary method of getting a fast swap execution.

Typically maxpriority is used for lower-gas low-priority transactions where immediate execution is not required, but tipping the miner directly increases the probability the swap is still processed.
