What to know about Gram (Toncoin) and Tether

Gram (Toncoin) (GRAM)

Gram (formerly Toncoin, TON) is the native coin of The Open Network, a blockchain originally designed by the Telegram team. After Telegram stepped away from the project in 2020, development was continued by the community and the TON Foundation.

Sending and receiving GRAM

TON addresses come in two formats (starting with UQ or EQ) that point to the same account. Exchanges usually require a comment (memo) with deposits — without it the funds may not be credited. Transfers take a few seconds.

Tether (USDT)

Tether (USDT) is the largest stablecoin: a token designed to stay at one US dollar. It was launched in 2014 by Tether Limited, which issues USDT against reserves that consist mostly of cash equivalents and short-term US Treasury bills.

Where to store Tether

USDT can be held in any wallet that supports the chosen network. Check that the wallet shows the official USDT contract, because fake tokens with the same name exist.

Optimism network

Optimism is an Ethereum layer-2 network. Addresses use the Ethereum format and fees are paid in ETH at a fraction of mainnet cost.
