Overview

Introduction

The Matchain Liquid Staking Protocol enables MAT token holders to earn staking rewards without locking up their assets. By depositing MAT into the LiquidStakingPool, users receive stMAT — a liquid, non-rebasing ERC-20 token that represents their staked position.

stMAT can be freely transferred, integrated with DeFi protocols, or held to accrue staking rewards through an increasing exchange rate mechanism. Rewards are delivered by reflecting the growth of the underlying MAT balance in the exchange rate, not by adjusting user balances.

Key Parameters:

• Liquid Staking Processing Fee: A protocol-level fee taken from staking rewards:

  • Default: 10%

  • Maximum: 20%

• Unbonding Period: 7 days (1,209,600 blocks) for standard unstaking requests.

• Flash Unstake Fee: A configurable fee (percentage defined) charged for immediate withdrawals via the flash unstake feature.

• Fee Vault: The designated address where accumulated protocol fees are sent for distribution among predefined beneficiaries.

Contract Audit

To ensure the highest standards of security and reliability, the Matchain liquid staking protocol underwent a comprehensive smart contract code review and security analysis conducted by Decurity, a leading web3 security audit firm. The audit assessed the contract logic, potential vulnerabilities, and adherence to best practices.
