Moonshot SDK for EVM helps calculate moonshot token prices at any point in the bonding curve. The package also allows the users to generate buy and sell transactions, provide the slippage amount and fix it to a trading side.
By Following the example you can create your high-performance trading bot within minutes.
Install the package using yarn
or npm
npm i @wen-moon-ser/moonshot-sdk-evm
# or
yarn add @wen-moon-ser/moonshot-sdk-evm
