Execution is a venue story
Best AI Trade Execution
Nobody can honestly sell “best execution” while hiding who matches the trade.
Non-custodialYou sign every tradeAI is informational
What this search should actually mean
OpenFidex does not match your order against a house book. You sign a transaction that a third-party venue handles. Fill quality is slippage, book depth, and network conditions — not a slogan.
AI belongs in the preparation: what you are looking at, whether the ticket is complete, whether a stop exists. Once you approve, execution quality is slippage, book depth, and network conditions — not a slogan we can print in lime.
How people actually start
Three moves. None of them hand OpenFidex your funds.
Complete the ticket
Size, side, invalidation. AI cannot rescue a blank field you were too excited to fill.
Accept fill uncertainty
If you need a guaranteed print, you are not in a public mempool-shaped world.
What the software is built to do
You are the sender
That single fact knocks out most “our AI executes” copy as either false or custodial.
Prep reduces fat-fingers
A clearer ticket is a real execution improvement. It is not alchemy.
No house internalization story
We are not quietly the other side of your trade.
Fast is not the same as best
See the fastest-execution page for latency. This page is about honesty of the fill.
Questions this page actually answers
Do you smart-order-route across CEXes?
No CEX SOR costume. You choose a path and you sign it.
Can AI pick a better limit?
It can inform. It does not get to send a revised order because it felt clever after you stood up.
What if a fill looks wrong?
Check the venue record. Support can help you read software. It cannot unwind a chain.
Is MEV part of execution?
On public networks, adversarial ordering exists. That is a venue/network fact, not a feature we can abolish with CSS.
Does OpenFidex hold my funds or place trades for me?
No. OpenFidex is a non-custodial software interface. A wallet is created in your browser, you keep the keys, and you cryptographically sign every order before it reaches a third-party venue such as Hyperliquid. The software does not take custody of assets and does not submit transactions unless you sign them.
