Sumer is a blockchain liquidity infrastructure with efficiency and security as the top priorities. Users can create synthetic suUSD, suETH and suBTC with the same lending deposit, enabling a travelers' check like experience for omni-chain DeFi and participation in new ecosystems while retaining native yields. Sumer’s unique Supernova core is a high performance EVM engine providing web2 level of experience in a highly decentralized network. The core will be contributed to the Cosmos SDK as a CometBFT alternative. This L1 provides additional utility and yield for synthetic assets, with the Sumer token serving as the PoS token for the blockchain.
