Currently, LayeZero supports Ethereum and EVM-compatible chains like: Avalanche, Polygon, BNB Chain, Fantom, Arbitrum, and Optimism.<\/span><\/p>\n To learn more about LayerZero, read the official documentation<\/strong> here<\/a><\/strong>.<\/span><\/p>\n LayerZero engaged <\/span>Ackee Blockchain<\/span><\/a> to conduct security reviews of LayerZero and Stargate Finance protocols on a regular basis. The Ackee Blockchain security team has so far conducted 5 audits<\/strong>, several features of the LayerZero protocol are still under review and more are about to come. Here we publish the first results of our work.<\/span><\/p>\n In this blog post, we\u2019ll mention information about the following LayerZero audits<\/a>:<\/span><\/p>\n LayerZero proof-lib audit <\/b>was completed on March 11, 2022<\/strong> with a total time donation of 4 engineering days.
