USDT on WAX
USDT@wrap.alcor from the Alcor bridge, and the legacy USDT@usdt.alcor
USDT@wrap.alcor
The standard USDT on WAX is USDT@wrap.alcor, brought to WAX by the Alcor bridge. USDT deposited from Ethereum or BNB Smart Chain arrives as the same token whichever chain it came from, and can be withdrawn to any chain the bridge supports.
To deposit or withdraw, use the Alcor Bridge at /v/wax/bridge. A deposit from an EVM chain takes one transaction in your EVM wallet; the tokens are delivered to your WAX account with nothing to claim. For integration details see the Bridge API.
USDT@usdt.alcor (legacy)
USDT@usdt.alcor is the earlier USDT on WAX, bridged from EOS through IBC (ibc.alcor). It is now legacy: switch to USDT@wrap.alcor. The two swap 1:1 on Alcor in one transaction (order book market 999), and the Swap page offers the replacement when you select the legacy token.
