Self-custody means no one can reverse a mistake for you. So rather than ask you to be careful, NeuroWallet checks things before they happen.

​
Before a trade runs

Every token you’re about to buy is examined first. Not looked up on a list - actually measured, by simulating the trade against live on-chain state.
Some tokens take a cut of every transfer. That’s legitimate in some designs and a trap in others, but either way it breaks a trade priced as though it doesn’t happen. We measure the real tax on both buying and selling, and price your trade with it included.A token taxing more than 15% on sale is refused, because such a trade physically cannot complete - it would fail on-chain and cost you the network fee for nothing.
A honeypot is a token you can buy and then can’t sell. We test the sale before you buy: simulating the exit and confirming it succeeds. If it fails, the purchase is blocked and we say why.
A token with too little liquidity can’t absorb your trade at anything near the quoted price. Liquidity and volume are checked, and a token that can’t support the trade is flagged.
Large trades in shallow markets move the price against you. When the impact crosses a threshold, you’re shown the number and asked to confirm rather than finding out afterwards.
Sometimes the real cost of executing a trade - network fees, routing, bridging - is disproportionate to its size. When the cost is out of proportion, the trade is refused with the actual number, so you can trade a larger amount or wait for cheaper conditions.

​
Blocking versus warning

The distinction matters:
  • A buy can be blocked. If a token looks like a trap, we won’t help you into it.
  • A sale is never blocked by risk. Whatever you hold, you can always exit. Nothing traps you.
  • A warning is yours to overrule. Where the risk is one you can knowingly accept - an expensive route, high price impact - you’re shown what’s wrong and you decide. We don’t quietly refuse, and we don’t quietly proceed.
The last one is the point. A trade blocked for a reason you’d have accepted is its own kind of failure, so the checks that exist to inform you inform you, rather than deciding on your behalf.

​
Address checks

Before crypto leaves your wallet, the destination address is validated for the chain you’re sending on, and screened against sanctions lists. A sanctioned address is refused outright.
No check can tell whether an address belongs to who you think it does. Verify the destination yourself - a transfer to the wrong address is irreversible.

​
Protecting your account

App lock

Require Face ID, Touch ID or a fingerprint to open the app. Optional, and worth turning on if you carry balances.

Multiple sign-in methods

Link more than one way into your Neurobro Pass, so losing access to one doesn’t lock you out.

​
What other people can see

Leaderboards and trading profiles are social features, so it’s worth being clear about what they expose - and what you control.
  • Leaderboard visibility - appear publicly under your username, or anonymously.
  • Country flag - show or hide the flag beside your rank.
  • Trading profile - control whether others can open your profile and see your positions.
All three are settings, all three can be turned off, and none of them ever expose your wallet address, balances, or the total value of what you hold.

​
What we can and cannot do

Worth stating plainly, since “non-custodial” gets used loosely:

​
If something goes wrong

A trade that fails on-chain doesn’t cost you the trade - failed transactions are detected and the order is closed out rather than left hanging. Where a multi-step trade moved money before failing, the app tells you where the money actually is instead of leaving you to work it out. For anything else, start with the FAQ or ask in the community.
