Tether tokens were created to use the Bitcoin network as its transport protocol — specifically, the Omni Layer — to allow transactions of tokenised traditional currency. Since this original version of the Tether token uses the Bitcoin blockchain, it inherits the stability and security of the longest established blockchain network.
Today, in addition to Bitcoin (Omni and Liquid Protocol), Tether tokens exist as digital tokens available on Ethereum, EOS, Tron, Algorand, Avalanche, Solana, OMG, Hermez (L2 ETH), Kusama, Tezos, and BCH (or SLP - Simpleledger protocol) blockchains. These transport protocols are composed of open source software that communicates with blockchains to facilitate the issuance and redemption of cryptocurrency tokens, in this case, Tether tokens.
Due to the fact that Tether tokens are now available via a variety of different transport protocols while sending Tether tokens to other addresses, it is essential to double-check the destination address to ensure you are using the correct transport protocol.
Note: You can also check Tether’s official site for information regarding the transport protocol.
