Web3 applications — also widely known as decentralized applications (dapps) — increasingly make it easy to connect your Ethereum wallet and get right down to business with little wasted time. But as with so many things, convenience often comes at the expense of security.

Digitally signing approvals to interact with web3 apps is an ordinary, necessary element of using distributed ledger technology like Ethereum. But those approvals are not completely without risks, as they can be attack vectors for malicious actors or points of vulnerability for buggy Ethereum contracts.

Good digital hygiene in web2 includes regularly reviewing account permissions for services like Amazon, Discord, Facebook, GitHub, Google, Instagram, TikTok, and Twitter — and revoking any permissions that no longer serve your needs. Likewise, good digital hygiene in web3 includes regularly reviewing your approvals — all those smart contract allowances that accumulate over time and permit dapps to access and move tokens in your wallet on your behalf.

Fortunately, there are a number of resources to help you with this endeavor, some of which I’ve listed below.
