StableSync — Automated Stablecoin Liquidity on Solana. Built for the Colosseum Frontier Hackathon 2026.
How it works
- You deposit stablecoins into a concentrated liquidity position on Orca Whirlpools
- A keeper bot monitors the price continuously and rebalances your position automatically
- Session keys allow non-custodial delegation — the keeper can only rebalance, never withdraw your funds
- Every rebalance is recorded on-chain as a PDA (Program Derived Address), giving you a full audit trail
- Accumulated yield can be collected at any time. You can close your position whenever you want.
Strategy: 80 / 10 / 10 Range Allocation
- 80% of capital is placed in the center range (±0.025% from the current price) — this is the tight band that captures the highest fee yield
- 10% is placed in the lower wing (below center) to capture downside price moves before rebalancing
- 10% is placed in the upper wing (above center) to capture upside price moves
- When the price exits the center band, the keeper repositions all three ranges around the new price
- Optimized for stablecoin pairs (low volatility) — tight ranges maximize fee capture without frequent out-of-range periods

Session Keys — Non-Custodial Delegation
- A session key is a limited-permission delegation from your wallet to the keeper
- The keeper is authorized to call rebalance on your position — nothing else
- Your funds stay in on-chain vaults controlled by the smart contract, not the keeper
- You sign the session key once during position creation. It expires automatically.
- You can revoke the session key at any time via the revoke_session instruction
