Three ways to work with us

The same desk serves the person buying their first USDT and the one moving six figures a month. The treatment changes, the standard does not.

Spot exchange

You set the amount in dollars, see the exact USDT you receive, and pay. Settled the same business day.

How it works

Four steps, none of them hidden

The baton changes hands four times. Every step says who performs it: you or us.

  1. You

    Open an account

    Your details, official ID and the source-of-funds questionnaire the law requires us to collect.

  2. Us

    We review

    Compliance reviews the file. We email you either way, and if the answer is no, we say why.

  3. You

    Quote and confirm

    Enter the amount, see the USDT you receive and authorise with a single-use code sent to your email.

  4. Us

    Receive in your wallet

    Once payment clears we send to the address you registered. The hash stays in your history.

Our standards

What we hold to in writing

  • No fee, at the real market priceWe quote at the asset's current price and add no fee: you receive the USDT your money buys at that moment, with taxes already included.
  • We do not custody your fundsGrindock does not open wallets on anyone's behalf. USDT goes to an address you own, and that is where our role ends.
  • Every trade is authorised twiceA password to get in and a single-use code to move money. That code expires in ten minutes.
  • Real compliance, not a formalityWe collect ID and source of funds under Mexico's anti-money-laundering law, and keep the file encrypted at rest.

What we ask of you

  • Official ID Voter ID, passport or professional licence. Front and back.
  • Occupation and source of funds Two questions on the form, required under the anti-money-laundering law.
  • Proof of address Upload it if you have it handy; it is also accepted later.
