THE ENDGAME FOR WALLETS IS OPEN MONEY

Summary from the TLDR Crypto newsletter

Traditional bank balances are claims on institutional ledgers ("closed money") and contrast with self-custody wallets that move assets directly on public networks, making money programmable and composable. MetaMask has built this out with mUSD, a wallet-native stablecoin earning up to 6% APY through onchain lending markets with no lockup, and a MetaMask Card that holds assets in self-custody until the moment of merchant payment. ERC-7710 delegation and ERC-7715 permission requests allow users to grant scoped authority to an AI agent, and x402 extends this to machine-to-machine HTTP payments per request. Wallets are becoming the permission layer through which user-delegated agents move money.
