The Mars wallet is currently undergoing an upgrade. At this time, minting NFTs and burning Mars for computing power may not be successful. Once the wallet upgrade is complete, airdrops and creator rewards will resume.

English：To enhance security and prevent malicious transactions, MarsChain’s technical team is currently strengthening node protection. Operations such as token withdrawals, NFT minting, and token transfers require communicating with and refreshing the node servers. To safeguard the network, our RPC (Remote Procedure Call) servers have rate limits in place. Consequently, frequent and rapid withdrawals, minting, or transfers will continuously trigger data refreshes, causing the node to temporarily block the address and result in an 'RPC error.' This issue has already been reported to the team, and the access permissions and limits are being adjusted.
中文：为了防止恶意交易保护大家的钱包安全和链上数据安全，amrschain官方提升了节点防护级别，我们的提币，转币，铸造nft都会造成节点的刷新，提高了限制便会限制单一地址的节点刷新频率，造成RCP error节点限制访问，造成的不便已经反馈，即将升级处理这个问题
