Biconomy Smart Account (Smart Contract Wallet) Overview

Biconomy Modular Smart Account is an EIP-4337 compatible modular smart contract wallet. Smart Account is ownerless by nature. UserOp and txns validation happens in Authorization Modules.

Smart Account is designed in such a way that it is:

• Modular => highly customizable and extandable.
• Cheap to deploy proxy copies of an implementation (user wallets)
• Wallet addresses are counterfactual in nature (you can know the address in advance and users can have the same address across all EVM chains)
• Deployment cost can be sponsored

How to run the project

This project demonstrates an advanced Hardhat use case, integrating other tools commonly used alongside Hardhat in the ecosystem.

1. Install

> npm install
// or
> yarn install

2. Configure

Place a mnemonic in a .secret file in the root folder of the project.

3. Run

The project comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. It also comes with a variety of other tools, preconfigured to work with the project code.

Try running some of the following tasks:

npx hardhat test

// other
npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat node
npx hardhat help
REPORT_GAS=true npx hardhat test
npx hardhat coverage
npx hardhat run scripts/deploy.ts
TS_NODE_FILES=true npx ts-node scripts/deploy.ts
npx eslint '**/*.{js,ts}'
npx eslint '**/*.{js,ts}' --fix
npx prettier '**/*.{json,sol,md}' --check
npx prettier '**/*.{json,sol,md}' --write
npx solhint 'contracts/**/*.sol'
npx solhint 'contracts/**/*.sol' --fix

Performance optimizations

For faster runs of your tests and scripts, consider skipping ts-node's type checking by setting the environment variable TS_NODE_TRANSPILE_ONLY to 1 in hardhat's environment. For more details see the documentation.
