Usual ETH0 Review 2026: wstETH-Backed Synthetic ETH Explained

Usual ETH0 is the Ether product of the Usual protocol. It is a synthetic Ethereum-based asset that the protocol says is fully collateralized by Lido's wrapped staked ETH, or wstETH. It runs on Ethereum.

Usual itself is better known for USD0, a stablecoin backed by tokenized US Treasury bills, and for its USUAL token. The homepage frames the project as a way to return value to users instead of to a central issuer. ETH0 sits alongside USD0 and EUR0 in the protocol's product list.

The tracker records roughly $2.2 million of value locked in ETH0, up about 3.8% over seven days, with a listing date of late February 2026. That makes it a small product with a short record. The team, the mint and redemption terms and the ETH0-specific audit coverage are not set out in the material reviewed.

ETH0 is a synthetic Ether token. A synthetic asset is a token designed to track the value of another asset, here ETH, without being ETH itself. According to the tracker description, ETH0 is fully collateralized by wstETH, Lido's wrapped staked ETH. wstETH is a token whose value grows against ETH as Lido's staking rewards accumulate.

The protocol's help center lists ETH0 as ETH exposure backed by wstETH, next to its dollar token USD0 and its euro token EUR0. The material reviewed does not spell out the mint and redeem process for ETH0. In protocols of this type, users generally deposit approved collateral to receive the token and can later return it for the collateral, subject to the issuer's rules.

Usual's wider design routes protocol revenue to holders of its USUAL token rather than to a company, and the homepage says 90% of value goes back to users. How much of this reaches ETH0 holders in particular is not stated.

The material reviewed does not publish a fee schedule for ETH0. There is no stated mint fee, redemption fee or management fee.

Users would see any protocol charges in the Usual app and technical docs before confirming. Ethereum network gas applies to every transaction, and wstETH carries Lido's own staking fee structure underneath.

The Usual homepage lists audits by Paladin, Halborn, Spearbit, Cantina and Sherlock. A TVL tracker shows no audits attached to the ETH0 entry, so readers should check which contracts those audits covered. Audits reduce risk but do not remove it.

ETH0 carries layered risks: Usual's own contracts, Lido's wstETH contracts, and Ethereum itself. A synthetic token can trade below its backing if confidence falls or redemption rules change. In January 2025, the protocol's USD0++ token fell to roughly $0.92 to $0.935 after Usual said its hardcoded $1 redemption price would drop to $0.87. That episode involved a different token, but it is relevant to how the protocol handles governance and terms.

The material reviewed does not describe the legal status of the issuer or any insurance for ETH0. The homepage mentions an insurance fund for USD0, not ETH0. Treat this as a smart-contract-based product with no deposit protection.

ETH0 is for DeFi users comfortable with liquid staking tokens, smart-contract risk and synthetic assets. It may interest holders of USUAL or users of other Usual products. It is not suited to beginners or to anyone who needs deep liquidity or deposit protection.
