jSOLi aggregates user deposits across multiple Liquid Staking Token (LST) protocols on Solana, automatically rebalancing to optimize yield. Users deposit SOL and receive jSOLi shares representing their proportional ownership.
- Aggregate SOL across multiple LST protocols (Jito, Marinade, BlazeStake, Jupiter)
- 25% Equal Weighting for maximum decentralization and yield stability
- Automated rebalancing based on APY optimization
- Share-based accounting (jSOLi token)
- Management and performance fees
- Emergency pause mechanism
- Two-step withdrawal with unbonding period
| Protocol | Allocation | Token | Est. APY |
|---|---|---|---|
| Jito | 25% | jitoSOL | ~7.5% (incl. MEV) |
| Marinade | 25% | mSOL | ~6.7% |
| BlazeStake | 25% | bSOL | ~6.8% |
| Jupiter | 25% | jupSOL | ~7.0% |
Target Blended APY: 6.9-7.3%
| Fee Type | Rate | Max Allowed |
|---|---|---|
| Management Fee | 0.5% annually | 1.0% |
| Performance Fee | 10% of gains | 20% |
- Features:
- ✅ Checked arithmetic (no overflow/underflow)
- ✅ Role-based access control
- ✅ Emergency pause mechanism
- ✅ Oracle staleness validation (60s max)
- ✅ Slippage protection on swaps
- ✅ Max 50% allocation per protocol

anchor deploy --provider.cluster devnet- User deposits SOL into the vault
- Vault calculates shares based on current TVL
- jSOLi tokens are minted to user
- SOL is allocated across LST protocols
- User requests withdrawal with jSOLi amount
- Vault creates
WithdrawRequestwith ~3 day unlock - User completes withdrawal after unlock period
- jSOLi is burned, SOL returned to user
- Triggered when any protocol deviates >5% from target
- Minimum 1 hour between rebalances
- Open to any caller (permissionless trigger)
- Slippage protection enforced
