Disconnecting Isn’t the Same as Revoking Wallet Permissions
Disconnecting from a DeFi app does not necessarily revoke the permission you gave it. Ethereum.org says token allowances can remain active after you disconnect—and may have no expiry. An unlimited approval can let a contract spend all of that token type held in your wallet. Binance Academy recommends reviewing approval requests carefully and revoking permissions you no longer need.
That makes approval hygiene a separate security habit: check the contract before signing, limit the amount where your wallet allows it, and review allowances on each network. Revocation is an on-chain transaction and can require a network fee.
My take: do not assume “disconnect” means “revoke.” Do you audit your wallet approvals regularly?
