MetaMask is ten years old. Most projects in the cryptocurrency industry do not survive for more than ten months. To put it bluntly, MetaMask is the most underestimated and underutilized infrastructure in the entire cryptocurrency industry. Everyone is using it, everyone is cursing, and few people want to pay. But the fact is - there's no fox in your browser toolbar, and the total market value of half of the industry doesn't even exist. ARB、STRK、ZK、APT， Those airdrops that change the fate of ordinary people, every check is cashed through MetaMask. DeFi Summer is not the story of Uniswap, nor is it the story of Aave. That's the story of MetaMask. It turned 'Connect Wallet' into an unexplained action. It has built highways for the entire encrypted world. They could have collected money at every toll station, set up checkpoints at intersections, and welded down guardrails. But they didn't. You can still download for free today, import mnemonic words, and completely leave their ecosystem. This is not a well-designed product. This is a bottom line that a team has maintained for ten years regarding the four words' self custody '. Happy birthday!
