Tether tokens exist as digital tokens built on several leading blockchains, including Algorand, Avalanche, Bitcoin Cash’s Simple Ledger Protocol (SLP), Ethereum, EOS, Liquid Network, Omni, Polygon, Tezos, Tron, Solana and Statemine. These transport protocols consist of open source software that interface with blockchains to allow for the issuance and redemption of Tether tokens.
Every Tether token is 100% backed by our reserves, which includes traditional currency and cash equivalents, and may include other assets and receivables from loans made by Tether to third parties.
The Tether platform is fully reserved when the sum of all Tether tokens in circulation is less than or equal to the value of our reserves. Through our Transparency page, anyone can view both of these numbers on a daily basis.
Tether was originally 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 Tether uses the Bitcoin blockchain, it inherits the inherent stability and security of the longest established blockchain network.
Tether on the Ethereum blockchain, as an ERC20 token, is a newer transport layer, which now makes Tether tokens available in Ethereum smart contracts or decentralized applications on Ethereum. As a standard ERC20 token it can also be sent to any Ethereum address.
Since Tether tokens are currently available using different transport protocols, when users send Tether tokens to other addresses, they need to carefully check the destination address to confirm they are selecting the correct transport protocol.
