🔧 Quick Start

💿 Clone the project

git https://github.com/Particle-Network/particle-bundler-server.git
cd particle-bundler-server
yarn

🧷 Setup the environment

Set your configuration in .env. We require the mongodb and redis. You need to transfer some native token to the Bundler Signer. Register the particle project at https://dashboard.particle.network/.

🏄🏻‍♂️ Start the project

npm run start

🖖 Start a gasless transaction

create a new terminal and run the test

npx jest rpc.controller.spec -t 'Gasless Basic' --chainId=${the chain you want to test}

🧷 Custom the bundler config

Set your configuration in /src/configs/bundler-config.ts.

• CHAIN_SIGNER_MIN_BALANCE: the minimum balance of the signer, if the signer's balance is less than this value, the payment signer will automatically transfer the token to the signer.
• CHAIN_VERIFYING_PAYMASTER_MIN_DEPOSIT: the minimum deposit of the paymaster, if the paymaster's deposit is less than this value, the payment signer will automatically transfer the token to the paymaster.
