Introduction
What is FUSDEV?
FUSDEV is a PYUSD0 yield vault on Flow EVM. The app gives users a simple deposit and withdrawal flow, live vault metrics, portfolio composition, and risk information in one place.
PYUSD0 yield on Flow EVM
FUSDEV is a Flow EVM vault for users who want PYUSD0 exposure with automated yield allocation and a live view of vault performance.
The production vault is on Flow EVM. The vault page also includes a Flow Testnet mode for previewing the same flow against testnet contracts.
- Deposit PYUSD0 through the vault interface and receive vault shares.
- Withdraw by redeeming shares back into the underlying asset.
- Track TVL, share price, APY, and portfolio composition from the vault page.
- Use testnet mode to preview the same workflow without using real assets.
Deposits and withdrawals
The app keeps the transaction surface simple: connect a wallet, approve the asset when needed, deposit, and withdraw from the same vault account.
- Deposits mint vault shares based on the current exchange rate.
- Withdrawals redeem shares for the vault's underlying asset.
- The interface shows asset decimals, share balance, allowance, and transaction state before submission.
- Users should review wallet prompts and network selection before signing.
How performance is shown
The vault page surfaces performance in user-facing terms rather than internal position mechanics.
- Share price tracks the value of one vault share over time.
- APY is calculated from historical exchange-rate movement and is shown for 7D and 30D views.
- TVL reflects the latest available vault valuation from the live data.
- Portfolio composition groups holdings into idle assets, deployed positions, LP exposure, and pending rewards.
How composition is grouped
Composition is presented as a user-facing portfolio view. Network rows can be expanded on the vault page, while the top-level view keeps the allocation categories easy to scan.
Assets currently held directly by the vault.
Deployed positions intended to earn yield from external vaults or lending markets.
Liquidity Provision exposure shown as its own portfolio bucket.
Accrued rewards that have value but may not yet be claimed.
Risks worth knowing
Vaults are not bank accounts. Users should understand the primary risk categories before depositing.
A vulnerability in the vault or a connected venue could cause loss of funds. Audits and monitoring reduce risk but cannot remove it.
The vault is denominated in PYUSD0 and may interact with other stable assets. Peg or redemption issues can affect vault value.
Withdrawals depend on available liquidity and the vault's ability to unwind positions under current market conditions.
Dashboard values are live operational data. They can be delayed when external data providers are unavailable.
Contracts and governance
These are the public values surfaced by the app. Contract links open in the Flow EVM explorer when an address is available.
Common questions
