Watch out

Exchanges often ask for a comment (memo) with a TON deposit. If the recipient gave one, enter it.

FAQ

Is EQ the same as UQ on TON?

Yes, the same account. The flag only decides whether a transfer to a not-yet-deployed wallet bounces back. Wallets now display UQ for wallets.

Do TON deposits need a comment?

Exchanges often ask for one. If the deposit page shows a comment or memo, enter it.
