What to know about Tether and Cosmos

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.

Sending and receiving USDT

The key choice is the network. USDT on TRON is popular for its low fees and speed, ERC20 is supported almost everywhere but costs more in gas, while Solana, TON and BEP20 are cheap alternatives. The recipient address must belong to the same network you send on, and you need the network's native coin (TRX, ETH, BNB…) to pay the fee from your own wallet.

Cosmos (ATOM)

Cosmos (ATOM) is the coin of the Cosmos Hub, the first chain of the Cosmos ecosystem, launched in 2019. Cosmos is often called the "internet of blockchains".

Risks and things to know

A missing Memo is the most common deposit problem. Staked coins cannot be moved during the unbonding period.

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.

How to exchange Tether to Cosmos

Enter the USDT Optimism amount in the calculator (minimum 200 USDT Optimism) and click “Go to exchange”.
Enter your ATOM wallet address on the Cosmos Hub network and your contact details. If you receive to an exchange, add the Memo.
Send exactly the specified amount of USDT Optimism on the Optimism network to the details shown in the order.
Once the transfer is confirmed, Cosmos is sent to your address. You can track the order on its status page.
