Tether (USDT): one coin, many chains

TetherUSDT is the largest USD-pegged , and a defining feature of it is that the same token is issued on many different chains — EthereumETH (ERC-20), TronTRX (TRC-20), SolanaSOL (SPL), several Ethereum L2s, and (historically) the on Bitcoin — an overlay that encodes its token transfers in data outputs (covered in the Technology unit). These are separate deployments: USDT on Ethereum and USDT on Tron are issued by the same company and redeemable 1:1 with the issuer, but they live on different networks and are not directly fungible across chains. To move value between them you must either redeem with the issuer or use a .

Tether issues USDT itself on each chain it supports, but the deployments are separate: to move value between them, you redeem with the issuer or use a bridge. On other chains, “USDT” is a bridged claim, with bridge risk on top.
Natively issued vs bridged

On each chain Tether natively supports, USDT is by Tether itself. On chains it doesn’t directly support, any "USDT" you see is a — a claim backed by assets locked elsewhere. Bridged USDT carries bridge risk on top of stablecoin risk. Always confirm which variant you’re holding.
