LendMixer

A minimalist flash loan service that supports all tokens compatible with the ERC-20 token standard.

Introduction

LendMixer is a lightweight flash loan service offering the following features:

1. Users enjoy the flexibility to customize token settings, allowing the service to seamlessly support a diverse range of tokens.
2. By depositing ERC-20 tokens in the allow list, users can earn revenue when withdrawing.
3. Initiating a flash loan incurs a minimal fee of only 0.3%.

In addition to ERC-20 tokens, our service also supports the native Ether token, and the WETH (Wrapped Ether) is provided for seamless integration.

1. WETH supports a flash Mint mechanism, enabling users to acquire a substantial amount of wrapped tokens seamlessly.
2. For enhanced flexibility, we provide support for ERC-20 extensions such as ERC-677 and ERC-3156.
3. Best of all, WETH does not incur any fees

Usage

The service is currently under testing and will be available on the mainnet soon.
