# FAQ

The most common questions about USD8, sUSD8, term locks, redemptions and Gram.

<details>

<summary>What is USD8?</summary>

USD8 is a dollar token on HyperEVM, minted 1:1 against USDC and fully backed by reserves held by the mint vault. It is the stable base layer of the protocol — it does not rebase and its price target is $1.

</details>

<details>

<summary>How does sUSD8 earn yield?</summary>

sUSD8 is an ERC-4626 staking vault over USD8. Protocol yield is delivered to the vault daily and vests linearly over 8 hours, which raises the NAV — the USD8 value of each sUSD8 share. You earn by holding the share; there is nothing to claim.

</details>

<details>

<summary>Where does the yield actually come from?</summary>

From real assets, off-chain. Reserves sit in a dedicated fund, managed by an independent asset-management company, and are invested in conservative fixed income — primarily government bonds, typically held to maturity. The confirmed daily return is minted on-chain under a two-person approval process. See [Reserves](/transparency/reserves.md) and [How Reserves Are Managed](/transparency/how-reserves-are-managed.md).

</details>

<details>

<summary>What are term locks?</summary>

You can lock sUSD8 for 30, 60, 180 or 364 days to earn a boost multiplier (up to 1.50×) on top of base yield. Each lock mints a transferable ERC-721 certificate; at maturity you claim principal plus the accrued boost. Early exit is not possible.

</details>

<details>

<summary>How do redemptions work?</summary>

Redeeming USD8 back to USDC starts a cooldown (T+7 days by default). Your USD8 is escrowed by the vault during the countdown and the request can be cancelled anytime before claim.

</details>

<details>

<summary>Is unstaking sUSD8 also delayed?</summary>

No — unstaking sUSD8 to USD8 is currently instant, at the prevailing NAV. (The T+7 cooldown applies to redeeming USD8 back to USDC, not to unstaking.)

</details>

<details>

<summary>How can I verify the reserves?</summary>

All protocol figures on the site are read directly from the contracts. The transparency page publishes supply, NAV history and reserve disclosures — anyone can re-derive them on-chain. See [Reserves](/transparency/reserves.md).

</details>

<details>

<summary>Is the protocol audited?</summary>

Yes — the contracts have been audited by Hashlock, and the core token and staking machinery is a minimal-diff fork of Ethena's audited USDe/sUSDe architecture. Read the [full audit report (PDF)](https://assets.usd8.ai/audits/usd8-smart-contract-audit-hashlock-2026-09.pdf) or see [Security & Audits](/transparency/security-and-audits.md).

</details>

<details>

<summary>What is Gram?</summary>

Gram is the protocol's points system — earned daily by holding USD8, staking sUSD8, locking terms and referring friends. It is not a token, but it is the protocol's permanent record of early participation. See [Gram Points](/rewards/gram-points.md).

</details>

<details>

<summary>Which wallets and networks are supported?</summary>

Any EVM wallet (MetaMask, Rabby, OKX Wallet, WalletConnect-compatible wallets). The protocol lives on HyperEVM mainnet, chain ID 999. See [Connect Your Wallet](/getting-started/connect-your-wallet.md).
