Solayer builds Solana's first yield-bearing stablecoin with an annual yield of 8%+
🌐 Treasury yield support, sUSD redefines stablecoins
The Solayer USD (sUSD) launched by Solayer is the first yield-bearing stablecoin on Solana backed by treasury bond yields. Users can deposit SOL or USDC to mint sUSD and automatically participate in the distribution of U.S. Treasury bond yields, with the current annual yield rate reaching 8.2%. On-chain data shows that on its first day, sUSD's TVL surpassed $20 million, with over 10,000 users obtaining dual yields through staking sUSD: stablecoin appreciation + treasury interest.
💎 Cross-chain interoperability, unlocking new DeFi gameplay
sUSD supports 1:1 cross-chain exchanges with mainstream stablecoins like USDC and USDT, with transaction fees as low as 0.1%. Through Solayer's cross-chain bridge, users can seamlessly transfer sUSD to Ethereum, Polygon, and other 17 public chains to participate in cross-chain lending, liquidity mining, and other scenarios. For example, staking sUSD on Aave V3 can earn an additional 0.5% APY boost, maximizing returns.
🔒 Over-collateralization + algorithmic adjustment, dual security guarantee
sUSD employs an over-collateralization mechanism, maintaining a collateralization rate of over 150%, with collateral including SOL, USDC, and Treasury bond certificates. When the price of sUSD deviates from $1, the protocol automatically initiates algorithmic adjustments: if below $1, it burns sUSD and releases collateral; if above $1, it issues more sUSD and locks more assets. Formal verification by the Fuzzland team shows that the sUSD system has a 99.99% probability of resisting a 51% attack.
