USDT0 is the omnichain version of Tether's USDT, issued as a LayerZero Omnichain Fungible Token (OFT) and operated by Everdawn Labs. It launched in early 2025 as a way to deploy USDT to new chains without Tether minting native supply on each one. Instead, real USDT is locked on Ethereum and a wrapped OFT representation, branded USDT0, mints on the destination chain. Supply is tracked at DeFiLlama.
​

USDT0 is issued and operated by Everdawn Labs under a license from Tether, not by Tether directly. Each USDT0 token is backed 1:1 by real USDT held in a lockbox contract on Ethereum mainnet. The token is the wrapped representation, not the underlying reserve, so its credit risk is Tether's reserve risk plus the additional bridge and LayerZero layer.
​

Tether announced the USDT0 partnership in a January 2025 post on its site, describing Everdawn Labs as the deployment partner for chains where Tether did not want to operate a native mint. The structure mirrors how Bridge.xyz's issued USDC variants work for Circle on certain L2s, except USDT0 uses LayerZero's OFT standard rather than CCTP. Holders of USDT0 redeem by burning the OFT, which unlocks the equivalent USDT on Ethereum, then can swap to fiat through any Tether-supported off-ramp.
​

The distinction matters for treasury and accounting work. Native USDT on Tron or Ethereum is a direct Tether liability; USDT0 on HyperEVM is a claim on locked Ethereum USDT, secured by the OFT contract and the LayerZero DVN set that validates each transfer. For background on the underlying stablecoin's reserves, the Tether transparency page publishes quarterly attestations by BDO.
​

USDT0 follows the LayerZero OFT lock-mint pattern. USDT enters a lockbox contract on Ethereum; the OFT contract on the destination chain mints an equivalent USDT0 balance after the configured Decentralized Verifier Network (DVN) set confirms the cross-chain message. Burning USDT0 on the destination chain releases the underlying USDT back on Ethereum. There is no central bridge operator running the transfer; messages route through LayerZero's endpoint contracts.
​

The mechanics are documented in the LayerZero OFT docs. A transfer is two transactions: a send call on the origin chain that debits the user and pays the LayerZero messaging fee, and a receive call on the destination chain that mints USDT0 to the recipient address. DVNs are independent verifiers (Google Cloud, Polyhedra, and LayerZero Labs itself are common choices) that must each attest to the message before the destination contract executes. The exact DVN set for USDT0 is configured per chain pair and is part of the trust profile.
​

Compared with Circle's CCTP, which burns and mints native USDC on each chain with no wrapped representation, USDT0 always carries the wrapped-token layer. The original USDT never leaves Ethereum. That keeps Tether's mint and burn surface narrow but means every USDT0 holder is exposed to the OFT contract on their chain and to the LayerZero DVN configuration. For the CCTP comparison, see our CCTP explorer guide.
​

USDT0 deployed first on HyperEVM in early 2025 and has since expanded across a small set of newer EVM chains that lacked native USDT. As of Q1 2026 the live deployments include HyperEVM, Berachain, Plasma, Flare, Ink, and Unichain, with additional chains added on an ongoing basis. The canonical list and per-chain contract addresses live at usdt0.to.
​

Each deployment uses the same OFT contract pattern but a chain-specific address. HyperEVM has the largest USDT0 supply by a wide margin, reflecting Hyperliquid's pull on stablecoin liquidity. Berachain and Flare added USDT0 as part of their initial DeFi liquidity programs. Plasma, Ink, and Unichain followed during 2025 as each L2 launched mainnet. Etherscan-style explorers for each chain (Berascan, Routescan for Flare, Blockscout for Ink, Uniscan) show USDT0 holder counts and top accounts. For navigating these block explorers, see etherscan alternatives 2026 and top Ethereum block explorers 2026.
​

Notably absent from the USDT0 list are chains where Tether already mints native USDT: Ethereum, Tron, Solana, Avalanche, Polygon, BNB Chain, Arbitrum, Optimism, and Base. On those chains a user who wants USDT should hold native USDT, not USDT0, because the wrapped-token surface adds unnecessary risk when a direct Tether issuance exists.
​

USDT0 sits in a growing category of "issuer-blessed wrapped stablecoins" that use a third-party deployer to extend a major stablecoin to chains the issuer will not natively support. The table below compares the four main patterns in 2026.

The pattern to watch is the trust-surface column. Native USDT carries only Tether's reserve risk. USDT0 adds two layers above that: the LayerZero DVN set chosen for the deployment, and Everdawn Labs as the operator of the OFT contract and the lockbox. Bridge.xyz's issued USDC variants follow the same logic but use Bridge as the custodian and a different messaging system. For a direct USDT0 vs USDT walkthrough including fee and redemption differences, see USDT0 vs USDT.
​

USDT0 total supply across all chains is tracked publicly by DeFiLlama's stablecoin dashboard. The figure refreshes continuously and breaks down by deployment, so a treasury team can see HyperEVM versus Berachain versus Flare balances directly. As of Q1 2026 the supply sits in the low billions, dominated by HyperEVM, with Berachain a distant second.
​

The growth trajectory is tied to two flows. First, Hyperliquid's HyperEVM pulled USDT0 in as the default non-USDC stablecoin for traders who want USDT exposure on the chain. Second, new L2 launches that selected USDT0 over waiting for native Tether issuance added incremental supply. Anyone modeling capacity should pull live numbers from DeFiLlama's USDT0 page rather than trusting any cached figure, because the supply moves quickly when a new chain integrates.
​

USDT0 stacks three risk layers: Tether reserve risk on the underlying USDT, LayerZero DVN configuration risk on the cross-chain messaging, and Everdawn Labs operational risk on the OFT contract and lockbox. A holder of native USDT only carries the first; USDT0 holders carry all three. None has caused a USDT0 loss to date, but the stack is real and worth pricing in.
​

The Tether layer is the same risk every USDT holder runs. Tether publishes quarterly attestations by BDO and a daily reserve breakdown at tether.to/en/transparency. The historical concerns around commercial paper exposure have largely resolved as Tether rotated into US Treasuries through 2023 and 2024. Anyone uncomfortable with Tether's reserves should not hold USDT0 either, because USDT0 is a claim on USDT.
​

The LayerZero layer is configurable per deployment. Each USDT0 chain pair sets a required DVN list and a block confirmation threshold. A malicious or compromised DVN set could in principle approve a fraudulent mint on the destination chain. Mitigations are the multi-DVN requirement and the independent operators (Google Cloud, Polyhedra, LayerZero Labs); the residual risk is real but small. The LayerZero configuration docs describe how to inspect a given OFT's DVN set onchain.
​

The Everdawn layer is the newest. Everdawn Labs holds upgrade keys to the OFT contracts and operates the lockbox. Governance and key-management practices are documented at usdt0.to; the security model is comparable to other wrapped-token operators (WBTC's BitGo custody, for example). For users storing meaningful balances, treating USDT0 as a transit asset for active DeFi positions rather than a long-term store is the conservative posture.
​

Users moving between native USDT chains and USDT0 chains typically need two hops: bridge USDT to Ethereum, then mint USDT0 into the destination chain through the OFT. Eco Routes collapses that into a single intent. A user signs once, Eco's solver network handles the USDT leg through CCTP-equivalent USDT rails and Hyperlane, and the funds arrive as USDT0 on HyperEVM, Berachain, Flare, Ink, Unichain, or Plasma. Withdrawals route the same path in reverse, terminating in native USDT on the user's target chain.
