Pocket Universe
Transaction simulator that shows before you sign
What it is
Pocket Universe is a browser extension that acts as your last line of defense before signing any on-chain transaction.
Before you confirm in MetaMask or any other wallet, Pocket Universe simulates what will actually happen: what leaves your wallet, what comes in, and whether anything looks suspicious. It's like having a financial advisor read the contract before you sign, in real time, in under a second.
How it works
Install the Pocket Universe browser extension (Chrome/Firefox).
When you initiate any transaction, Pocket Universe intercepts it before the wallet popup appears.
It simulates the transaction and shows a clear summary: assets leaving, assets entering, approvals being granted.
If it detects a phishing site or malicious contract, it shows a warning before you can confirm.
You decide whether to proceed or cancel, you always have full control.
When to use it
Always install it once and it protects every transaction automatically.
Especially when interacting with new or unfamiliar DeFi protocols.
When minting NFTs from links shared on social media.
When you receive DMs with airdrop or claim links.
One of the highest ROI security tools available: free, passive, and catches mistakes before they happen.
