sTCY — Auto-Compounding
sTCY (Staked TCY) is a liquid yield asset within the THORChain ecosystem, powered by the AutoRujira team.

It is designed to give users compounding exposure to TCY, the token that directly captures 10% of Thorchain’s system income. Unlike holding raw TCY, sTCY automatically compounds rewards within the contract, eliminating the need for manual re-staking.
How does sTCY work?
At its core, sTCY is a wrapper around TCY deposits:
Deposit TCY → Get sTCY Users deposit TCY into the contract and receive sTCY in return. Rewards are continuously auto-compounded into the pool.
Redeem sTCY → Get TCY back Users can at any time burn sTCY to redeem their underlying TCY plus the compounded rewards.
Auto-Compounding Engine The contract continuously compounds rewards, increasing the value of each sTCY share relative to TCY over time.
💡 The share price (exchange rate between sTCY and TCY) gradually rises as rewards accumulate.
Fee Structure
The AutoRujira team, who developed and maintain the sTCY contract, collect a 5% fee on generated rewards.
Deposit Fee: None
Withdrawal Fee: None
Performance Fee: 5% of compounded rewards
This aligns incentives: users enjoy seamless compounding while the maintainers are compensated only when yield is generated.
Risks
As with any DeFi yield product, sTCY carries risks:
Asset risk → Exposure to TCY price fluctuations.
Smart contract risk → The underlying AutoRujira contracts are audited, but never risk-free.
Liquidity risk → TCY markets can be shallow, leading to volatility.
Protocol dependency → Changes in THORChain’s system income model could affect performance.
