According to CoinMeta, Ethereum developer Eric Conner has proposed ERC-8392, which aims to create a universal state interface for tokenized assets to address the mismatch between blockchain activities and the limited trading hours of traditional markets. This proposal allows tokenized stocks to be traded at any time, whereas the underlying stocks may not be tradable when exchanges are closed. Conner points out that smart contracts should respond differently depending on circumstances, such as pausing liquidations in the event of a data provider failure. The proposal includes multiple state queries that cover the asset lifecycle and operational status, and also proposes extensions to market state and valuation status. The aim of this proposal is to provide clearer operational information for both tokenized stocks and real-world assets, ensuring that investors can accurately understand the asset status even when markets are closed.
