Where to go

What to include

The more you send, the faster we can help:

  • Your wallet address. It identifies your account and is public anyway.
  • The transaction hash, if money moved or didn't. Look it up on a Base block explorer.
  • The market link, if your question is about a market.
  • The exact error message, and roughly when you saw it.
  • Your IP address, if you were refused access. See Who can use Ultramint.

What we'll never ask for

Anyone who asks for these isn't us:

  • Your private key or a sign-in code. Never.
  • An approval on something we sent you. You only approve things in the app, on a screen you opened.
  • A transfer to an address we give you. We never ask you to move funds, "verify" a wallet or "unlock" a payout.
  • A fee to release a payout. Payouts come from the market's contract. There's nothing to pay.

We only email you at the address on your account.

What support can't do

  • Reverse a transaction. Anything confirmed on-chain is permanent, including a withdrawal to the wrong address or a deposit on the wrong network.
  • Get you out of a position early. There's no selling.
  • Change a market's result. A public market's result changes only through a challenge. A Members only market's result is up to its creator.
  • Sign for you or move your money. Only you can sign for your account.
  • Make exceptions to the eligibility rules, or to taking your money out before closing your account.
