sYUSD (Yield-bearing Token)
Staked YUSD Overview
Overview
sYUSD is the yield-bearing, staked version of YUSD. When you deposit YUSD into the staking contract you receive sYUSD, which:
Represents your proportional share of the staking pool.
Automatically accrues BTC funding-rate yield.
Appreciates in value relative to YUSD over time.
Launch exchange rate: 1 sYUSD = 1 YUSD
Afterwards: 1 sYUSD > 1 YUSD as rewards accumulate.
The StakedYUSD smart contract implements the ERC4626 Token Vault standard for composability.
This popular standard is widely used for onchain reward-accruing; thus, it is expected that other user interfaces beyond the Aegis.im dAPP may likely support YUSD staking in the future. Various deposit and redeem functions are exposed, enabling staking with or without a slippage threshold, and with or without an ERC2612 Permit signature authorizing the transfer of YUSD.

FAQ
Question
Answer
Why isn’t it always 1 sYUSD = 1 YUSD?
Rewards are internalised; as the pool grows, each sYUSD is worth more YUSD.
Do I need to claim anything?
No, the rising exchange rate captures all yield automatically.
Will I still earn Aegis Points?
Yes, based on your sYUSD balance.
Is there any fee?
0% protocol fee; only network gas for stake/unstake.
