LendMixer

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

Logo

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.

The complete guide for the services please refers to the wiki
