Matchain is an EVM-compatible Layer 1 blockchain. The MAT token, its liquid staking pool system, ownership-NFT-gated pools, and a fee distribution vault are governed by upgradeable Solidity contracts deployed via beacon proxies.
Zealynx audited Matchain's liquid staking protocol, the MAT token reward distribution mechanism with halving emissions, the pool ownership NFT, the staking pool factory, and the fee distribution vault. The 6-day review identified 23 issues including 6 High severity (two reentrancy windows around the pool ownership NFT transfer, halving boundary reward miscalculations, exchange rate front-running, and reward starvation beyond the first 21 pools). 18 findings were fixed during the engagement and 5 were acknowledged.
Zealynx audited the Matchain Genesis License NFT and its companion NFT-staking contract for Immunefi. The 3-day review identified 14 issues including 1 Critical (reward dilution from a fixed denominator that ignores actual staked count), 1 High (front-running rewardDistribution() to capture rewards without time staked), and 1 Medium (mint replay protection missing a nonce). 4 issues were fixed and 10 were acknowledged.
When someone asks “is Matchain really audited?”, this is the page to send them. Every engagement we’ve delivered, in one place, with the artifacts.
