【MegaETH and Ethena jointly launch native stablecoin USDm to subsidize sorter fees】Golden Finance reports that MegaETH, a layer-2 scaling solution developed by MegaLabs, is launching a stablecoin named USDm on-chain. This stablecoin aims to replace traditional sorter margin and use reserve income to cover network operating costs. The model is built in collaboration with the decentralized finance protocol Ethena, aiming to coordinate on-chain and ecosystem incentives by running sorters at cost and keeping transaction fees for users and developers low and stable. Currently, multiple Layer2 networks are generating income by increasing sorter fees. USDm aims to solve this issue: when a project goes live on the mainnet, it will use the reserve income from the stablecoin to cover shared network costs. The first version of USDm will be issued on Ethena's USDtb protocol layer. A representative from MegaETH revealed to The Block that USDm will be exchanged for USDtb upon launch, rather than directly providing fiat redemption. The team did not disclose the target floating amount to cover daily operating expenses, stating that these parameters will be determined over time. Regarding other sources of income (such as MEV), MegaETH stated that relevant details will be announced before the mainnet launch.
