- USD1 Vault offers fixed yield via USD1, a stablecoin backed 1:1 by U.S. Treasuries and custodied by BitGo
- Users deposit USD1, USDT, or USDC on BNB Chain and earn scUSD1 with an auto-managed 6% APY strategy by CIAN
- Withdrawals take 5 days, with liquidity routed across 20+ blockchains via StakeStone’s unified interface
StakeStone has launched the USD1 Vault, a decentralized‑finance product designed with CIAN Protocol and backed by World Liberty Finance (WLFI). Announced this week, the vault gives users a direct path to fixed on‑chain yield through USD1, a stablecoin fully collateralized by short‑term U.S. Treasuries held at BitGo.
USD1 has already recorded more than $2.1 billion in issuances and listings on major exchanges including Binance, Bitget, and HTX. By integrating the new vault, StakeStone aims to satisfy surging demand for cross‑chain liquidity, routing assets across more than 20 blockchains while letting users manage everything through one interface.
How the vault works
Depositors can supply USD1, USDT, or USDC on the BNB Chain. Once funds are committed, the contract mints scUSD1 a token that represents the staked position and sits directly in the user’s wallet. StakeStone’s rebalancing engine, with automation provided by CIAN, allocates assets across vetted DeFi protocols to capture market‑driven opportunities and deliver an additional 6% yield in USD1.

CIAN’s risk engine monitors protocol health and yield curves, adjusting allocations to maintain the target rate while keeping collateral safely within strategies that meet its risk thresholds. WLFI, whose USD1 collateral base is audited and compliant, supplies the underlying stablecoin liquidity.
Withdrawal safeguards and multi‑address flexibility
Exits are handled through a request‑and‑queue system. Each wallet can maintain only one active withdrawal request; however, users can split scUSD1 across multiple addresses to initiate several requests concurrently. The CIAN team processes redemptions on a five‑day rolling cycle. After settlement, the equivalent amount of USD1 is automatically delivered to the requesting wallets, creating a transparent and predictable off‑ramp.
By combining a fully collateralized stablecoin, automated yield optimization, and broad cross‑chain reach, StakeStone says the USD1 Vault “unlocks a new era of DeFi utility.” For users still navigating fragmented liquidity and variable yields, the product offers a one‑stop solution built around security, compliance, and consistent returns.
