StableSync

Automated concentrated liquidity management for stablecoin pairs on Solana — non-custodial, set and forget.

What it does

Stablecoin LPs on Solana lose money when their position drifts out of range and stops earning fees. StableSync automates the rebalancing using session key delegation: the keeper can rebalance your position without ever having custody of your funds.

• Deposit into a USDC/USDT or USDC/USDS strategy
• Delegate a narrow rebalancing permission via session key
• Keeper monitors price via Pyth oracle and repositions automatically
• Withdraw at any time — you stay in control
