The project <a href=\"https:\/\/blog.usdt0.to\/usdt0-your-usdt-anywhere\" rel=\"nofollow noopener\" target=\"_blank\">launched on January 16, 2025<\/a>, on Ink, an Ethereum layer 2 (L2) network created by the Kraken exchange. USDT0 uses LayerZero\u2019s <strong>OFT (Omnichain Fungible Token)<\/strong> standard, which allows tokens to move between blockchains without changing their total supply. Everdawn Labs developed the contracts, and the project is run by the USDT0 consortium in partnership with Tether and LayerZero.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">USDT0\u2019s backing is held on Ethereum. When a user transfers USDT from Ethereum to a USDT0 network, the OFT Adapter contract, also known as a <strong>lockbox<\/strong>, locks the deposited USDT, and the corresponding amount of USDT0 is minted on the destination network. Subsequent transfers between connected networks use a <strong>burn-and-mint<\/strong> mechanism: tokens are burned on the source network, and the same amount is minted on the destination network once the LayerZero message has been verified. Each USDT0 in this system is backed by one locked USDT.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">As of October 20, 2026, the <a href=\"https:\/\/docs.usdt0.to\/technical-documentation\/deployments\" rel=\"nofollow noopener\" target=\"_blank\">official list of USDT0 networks and contracts<\/a> covers 24 networks, including Arbitrum, Optimism, Polygon, Berachain, Ink, HyperEVM, Plasma, Mantle, Monad, Unichain, Sei, Stellar and Hedera. Ethereum is also listed, but <strong>there is no separate USDT0 token on Ethereum<\/strong>: adapter contracts lock and unlock regular USDT.

Because USDT0 is backed by USDT locked on Ethereum, holding it exposes you to both Tether\u2019s risks and those of the <strong>USDT0 contracts and LayerZero infrastructure<\/strong>.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"nm-block-heading wp-block-heading\">How tokens move between networks<\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">A regular transfer can only send USDT within the same blockchain. Moving funds from Tron to Arbitrum, for example, requires a separate route: an exchange that allows withdrawal on another network, a supported bridge or Legacy Mesh. When choosing a third-party bridge, check exactly which asset you will receive. Some bridges issue their own wrapped token with a different contract and additional risks.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/usdt0.to\/transfer\" rel=\"nofollow noopener\" target=\"_blank\">official USDT0 Transfer service<\/a> supports transfers between connected USDT0 networks. A standard OFT route has no separate fee in USDT, but you pay gas and the LayerZero messaging fee in the source network\u2019s native coin, such as ETH on Arbitrum or POL on Polygon. The interface may also offer a faster route for an additional fee. Before confirming, check the selected route and the amount you will receive; after sending, track the transfer status against the service\u2019s estimated completion time.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"nm-block-heading wp-block-heading\">Legacy Mesh: connecting Tron, TON and Solana to USDT0<\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/docs.usdt0.to\/overview\/the-legacy-mesh\" rel=\"nofollow noopener\" target=\"_blank\">Legacy Mesh<\/a> connects networks with native USDT\u2014Ethereum, Tron, TON, Solana and Celo\u2014to USDT0 networks through a central hub on Arbitrum. A transfer from Tron to Plasma, for example, uses liquidity pools: USDT is locked in the Tron pool, and once the message is verified, the Arbitrum pool releases the corresponding amount of USDT0. From there, USDT0 moves to Plasma through burn-and-mint. You can complete the transfer through a single service, although a token spending approval may require a separate confirmation.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Legacy Mesh charges <strong>0.03% in USDT<\/strong>, or 3 USDT on a 10,000 USDT transfer, in addition to network costs. If you received TRC-20 USDT on Tron, this route lets you move it to a supported USDT0 network without going through an exchange or receiving a third-party wrapped token.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"nm-block-heading wp-block-heading\">Additional risks<\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/docs.usdt0.to\/technical-documentation\/security\" rel=\"nofollow noopener\" target=\"_blank\">USDT0\u2019s verification system<\/a> requires confirmation from <strong>all three Decentralized Verifier Networks (DVNs): LayerZero, USDT0 and Canary<\/strong>. Compromising one of them is not enough to validate a forged message. Guardian, ChainSecurity and Paladin have audited the contracts, and the project runs a <a href=\"https:\/\/immunefi.com\/bug-bounty\/usdt0\/information\/\" rel=\"nofollow noopener\" target=\"_blank\">bug bounty program on Immunefi<\/a>. The maximum reward for a critical vulnerability is $6 million for Ethereum Virtual Machine (EVM)-compatible networks and $1 million for non-EVM networks.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">On most EVM networks, USDT0 contracts use an <strong>upgradeable proxy<\/strong>, allowing their logic to be updated without changing the contract address. Administrative operations are controlled by a multisig wallet, which requires signatures from multiple key holders to authorize an operation. The contract owner also manages an <a href=\"https:\/\/docs.usdt0.to\/technical-documentation\/token-features\/additional-behavior\" rel=\"nofollow noopener\" target=\"_blank\"><strong>address blocklist<\/strong><\/a> that can restrict token operations.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">When deciding how much to hold in USDT0, account for the risks of its contracts and cross-chain transfer system. Switching to native USDT removes your reliance on those contracts and that transfer system, while issuer and freezing risks remain.

Verify the transaction and contract, then add the correct token. Never share your seed phrase with anyone offering to \u201csynchronize your wallet\u201d or help display your balance.<\/li>\r\n\r\n\r\n\r\n<li><strong>A counterfeit token is named USDT0 or USD\u20ae0.<\/strong> Names and icons can be copied, so verify a token by its contract on the specific network.

Another tactic is address poisoning: transactions involving addresses that resemble your recipients\u2019 addresses appear in your history, in the hope that you will copy one by mistake.<\/li>\r\n\r\n\r\n\r\n<li><strong>A service uses different deposit addresses for different assets.<\/strong> Even on the same network, an address for one token may not accept another.

Your wallet may therefore let you send USDT0 even though the exchange accepts deposits to that address only on another network.

On a standard USDT0 Transfer route, you also use that coin to pay the LayerZero messaging fee.

The same EVM account will usually have the same address on Arbitrum, Optimism and Polygon. USDT0 works differently on Stellar, Hedera, HyperCore and IOTA, so check network and token support separately. For help choosing a network and storage method, see our guide <a href=\"https:\/\/lwallet.com.ua\/en\/hardware-wallet-usdt\/\">Where to store USDT: which network and wallet to choose<\/a>.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">If the manufacturer\u2019s app does not display USDT0 on the EVM network you need, open a compatible app such as MetaMask or Rabby, select its option to add a hardware wallet and connect your device. <strong>Your private key stays on the device, and you do not need to enter your seed phrase to connect it.<\/strong><\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">On most networks, USDT0 supports <strong>EIP-2612 (permit)<\/strong>, which lets you grant a token spending allowance by signing a message, and <strong>EIP-3009 (transferWithAuthorization)<\/strong>, which lets you sign an authorization for a specific transfer. Creating either signature does not send a transaction or cost gas, but another party can submit it to the contract and carry out the authorized action. The <a href=\"https:\/\/docs.usdt0.to\/technical-documentation\/token-features\/eip-2612\" rel=\"nofollow noopener\" target=\"_blank\">deadline field in permit<\/a> limits when the signature can be submitted, while <strong>an allowance already set on-chain may remain valid after that date<\/strong>. Available features vary by network: Polygon PoS, for example, supports permit but not EIP-3009. The differences are listed in the <a href=\"https:\/\/docs.usdt0.to\/technical-documentation\/token-features\/\" rel=\"nofollow noopener\" target=\"_blank\">USDT0 feature support table<\/a>.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">USDT on Ethereum has no built-in support for these two standards, but that does not make every signature involving it safe: approvals can also work through other contracts, including Permit2. If a token supports permit or transferWithAuthorization, a scammer can disguise a spending approval or transfer authorization as a login confirmation and trick you into signing it. <strong>Even a signature that costs no gas can grant access to your tokens.<\/strong><\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Before confirming, check the message type, network, token contract, the address you are authorizing or sending funds to, the amount and the expiration time. Review the details on your hardware wallet\u2019s screen if the device can display them for that request. If it only shows a hash instead of readable fields, you are being asked to blind sign, without seeing the decoded contents. Reject the request if you cannot verify what you are authorizing. When using DeFi, check how your model and current firmware display the service\u2019s specific request: the EIP-712 structured data fields you are signing should be readable. A device may support EIP-712 yet still fail to display some requests in full. For more on reviewing operations on the device\u2019s screen, see our guide to <a href=\"https:\/\/lwallet.com.ua\/en\/clear-signing-blind-signing\/\">Clear Signing and Blind Signing<\/a>.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">[vc_message color=&#8221;warning&#8221; message_box_style=&#8221;classic&#8221; message_box_color=&#8221;alert-warning&#8221; style=&#8221;rounded&#8221;]<strong>If you signed a suspicious permit or transfer authorization, move your USDT0 to another address you control as soon as possible.<\/strong> Then review and revoke active approvals through a verified service such as <a href=\"https:\/\/revoke.cash\/\" rel=\"nofollow noopener\" target=\"_blank\">Revoke.cash<\/a>. Revoking an active allowance does not necessarily invalidate a signature that has not yet been used in a transaction. Do not return funds to the old address until you have established whether that signature is still valid. If you entered your seed phrase on a third-party website, move all accessible assets to a new wallet with a new seed phrase.[\/vc_message]<\/p>\r\n\r\n\r\n\r\n<h2 class=\"nm-block-heading wp-block-heading\">What to do if a transfer goes wrong<\/h2>\r\n\r\n\r\n<div class=\"wp-block-image wp-block-image size-large is-style-default blog-img\">\r\n<figure class=\"aligncenter\"><img decoding=\"async\" width=\"1024\" height=\"573\" src=\"https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-1024x573.jpg\" alt=\"Tracing a mistaken USDT0 transfer using its transaction hash\" class=\"wp-image-75068\" title=\"\" srcset=\"https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-1024x573.jpg 1024w, https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-766x429.jpg 766w, https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-300x168.jpg 300w, https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-1536x860.jpg 1536w, https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-679x380.jpg 679w, https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1-349x195.jpg 349w, https:\/\/lwallet.com.ua\/wp-content\/uploads\/2026\/10\/blog-usdt-vs-usdt0-22-10-2026-content-pic7-1.jpg 1631w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n<ol class=\"nm-block-list wp-block-list\">\r\n<li><strong>Stop sending funds to the same address.<\/strong> Another test transfer will not fix the mistake and will only increase the amount you need to recover.<\/li>\r\n\r\n\r\n\r\n<li><strong>Save the transaction details.<\/strong> Find it in the source network\u2019s block explorer and copy the transaction hash, network name, recipient address, token contract and amount.
