Common questions: OPEN → GRAM

What rate does OPEN to GRAM run at?

As of Sep 17, 2026 00:38 it is 1 OPEN = 0.103788 GRAM. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.135962.

What amounts does OPEN → GRAM accept?

From 1,502.63 to 74,500,000 OPEN per order. The lower limit is roughly $201.66.

Where does the 1,502.63 OPEN floor come from?

Network fees and order handling eat a small transfer alive — below 1,502.63 OPEN the swap stops making sense for either side.

What else is taken on top of the rate?

The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending OPEN, and that one goes to the blockchain, not to us.

How long does OPEN to GRAM take?

The clock starts with confirmations: the order goes into work once OpenLedger confirms your transfer. After that it comes down to how busy the network is.

Which network will GRAM arrive in?

Gram (Toncoin) leaves in its own TON network — a plain GRAM address is all you need. Some exchanges and wallets also need a Comment (Memo).

What if the rate moves while I am paying?

The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.

Can I go back, GRAM to OPEN?

Yes, the reverse direction is open: 1 GRAM = 9.6835 OPEN. The link sits right under the calculator.
