Insights, guides, and deep dives into token allowances, wallet defence, and DeFi best practices.
Four approval shapes, each looking almost identical in the wallet modal, each with its own trust implications. A reference for reading what you are actually signing before you sign it.
Six of the eight largest DeFi hacks between 2022 and 2024 had nothing to do with user token approvals. The seventh and eighth tell us where approval hygiene actually matters — and where it cannot help.
True digital sovereignty requires a shift from digital convenience to physical security. Hardware wallets and multisigs create layers of defence that are nearly impossible for remote attackers to penetrate.
Every wallet decodes the transaction you are about to sign a little differently. Some show you the token, the spender, the amount, the deadline; some show you a hash and wish you luck. A practical comparison of the six most-used wallets on the specific question of whether you can read what you are signing.
A smart contract you have never interacted with is asking for an approval. You have roughly ninety seconds before the moment passes. Four lenses — bytecode, source, deployment history, and on-chain behaviour — give you enough signal to decide without needing to be a Solidity engineer.
A classic ERC-20 approval is revoked by writing zero on-chain. A Permit2 approval lives in a different place, expires on a different clock, and sometimes never touched the chain at all. A short walk-through of what Permit2 revocation actually looks like and when you still have to do it.
For a decade, approve() was the only way a wallet granted a contract the right to move a token. That model is quietly ending. Four distinct replacements are already live or near-live, each with its own security shape. A field guide to what is coming and what it changes.
AllowanceGuard flags risky contracts because someone, somewhere, saw one first and said so. A walk-through of what counts as a report worth making, what happens after you submit it, and why the community angle is the point — not a marketing line.
A no-install, no-account audit of every active token approval on your wallet across 27 chains. Five steps, ten minutes, one-click revoke for anything you do not want any more.
When you list an NFT on a marketplace, you sign something called setApprovalForAll. It gives a contract permission to transfer every NFT you own in that collection. Most holders click through it without thinking.
Blind signing, Permit2 signature trees, intent swapping, gasless off-chain signatures. Four attack vectors your wallet UI cannot fully protect you from.
Assess, revoke, move, document, report. The order matters. Here’s what to do in the first hour after you realise you’ve been scammed.
