# Staked yzUSD (syzUSD)

syzUSD is a technical wrapper, an ERC‑4626 vault token that represents staked yzUSD for composability in DeFi. Staking converts form only (yzUSD → syzUSD) and is designed to facilitate integrations and secondary‑market use. Any yield accrual to syzUSD reflects the program’s policy for yzUSD staking and underlying portfolio performance; the wrapper itself confers no separate rights beyond representing the staked position.

**Yield Distribution:** Yield distributed to syzUSD is **decided weekly on Friday** and corresponds to the week’s epoch (Fri 04:00 UTC → Fri 03:59 UTC).

**Unstaking Window:** Unstaking syzUSD back to yzUSD is a one-step process, simply unstake and the process completes almost instantly.
