# Welcome to USD8

USD8 is the yield-bearing dollar on HyperEVM. Mint 1:1 against USDC, stake into sUSD8, lock a term for boosted yield — every figure verifiable on-chain.

**USD8 is the first yield-bearing stablecoin built natively on HyperEVM.** Mint it 1:1 against USDC, stake it into sUSD8 to earn daily yield, or seal a fixed term for a boosted multiplier — with every balance, NAV movement and reserve figure readable directly from the contracts.

> *Ex antiquo, in aeternum* — the discipline is ancient, the rails are new.

USD8 is built and managed by a team with years of experience at hedge funds and asset managers. Protocol yield comes from conservative, professionally managed reserves — not from token emissions — and is delivered on-chain every day under a two-person approval process.

**Audited by Hashlock.** The USD8 contracts build on Ethena's battle-tested, audited architecture and have been independently audited by Hashlock — read the [full report (PDF)](https://assets.usd8.ai/audits/usd8-smart-contract-audit-hashlock-2026-09.pdf) or see [Security & Audits](/transparency/security-and-audits.md).

## Why USD8

{% columns %}
{% column width="50%" %}
**Fully backed, 1:1**

Every USD8 is minted against USDC held by the mint vault — one dollar in, one USD8 out, with zero protocol mint fee.

**Native to HyperEVM**

Mint, stake and redeem settle on-chain. Every figure shown by the app is read live from the contracts — no trust in a dashboard required.
{% endcolumn %}

{% column width="50%" %}
**Yield through sUSD8**

Stake into the ERC-4626 vault and the NAV of your shares rises daily, verifiably. You earn by holding — there is nothing to claim.

**Terms sealed on-chain**

Lock sUSD8 for 30 to 364 days. Each lock mints a transferable certificate NFT that redeems principal plus boosted yield at maturity.
