I came across @strato_net and took a look at the underlying structure. It seems the chain has a rather early origin. It's based on the Haskell Ethereum client from 2014, developed by early Ethereum contributors (BlockApps). In 2015, it was one of six mainnet-compatible clients when Frontier launched. Later, it also worked on enterprise-grade blockchains and Blockchain-as-a-Service—basically, turning blockchain capabilities into services so others can use them directly without having to build a chain from scratch. Currently, this chain is working on HardFi, turning gold and silver (GOLDST, SILVST) from vaults into on-chain assets that can be directly used as collateral to mint USDST. Compared to existing gold tokens, GOLDST and SILVST, also on-chain certificates of physical gold assets, can be included in CDPs. The mainnet application currently supports depositing, staking, minting, exchanging, and providing liquidity. Fees are currently USDST or vouchers. TGE will be available in Q4, so if you want to see how it works, just go to the official website http://strato.nexus and open the mainnet application; it's very simple.
