Mainstream wallet applications are accelerating their multi-chain deployment. After supporting Bitcoin last month, they announced integration with the TRON ecosystem this week. This series of actions reflects that the wallet ecosystem is no longer limited to a single chain—starting from Ethereum, gradually including mainstream public chains like Bitcoin and TRON, and ultimately forming a cross-chain one-stop management solution. Users can manage assets across multiple chains on the same platform, which is very meaningful for simplifying operation processes and lowering usage barriers. As more public chains are supported, the role of wallets is also evolving, from auxiliary tools of chains to true asset centers.
