Solana LSD Stack ​

Solana LSD Stack is devoted to help developers building liquid staking project on Solana ecosystem and designed to provide a comprehensive set of solutions related to commission fee management, validator set management, and user operations: stake, unstake, withdraw.

Program ​

In the Solana ecosystem, "smart contracts" are called programs. Each program is an on-chain account that stores executable logic, organized into specific functions referred to as instructions.

Solana LSD program creates StakeManager and StakePool accounts for each LSD network.

Core Accounts:

• StakeManager: the main account of the LSD network that stores all the states such as: rate, validators and commission fee
• StakePool: an escrow account manages funds between stakers and native staking pool
• UnstakeAccount: an account stores unstake info such as: recipient and amount

Core roles:

• Owner: manages the LSD network

Stakers flows ​

Stake Flow ​

Users can stake SOL to the LSD network via stake method, and users will receive equivalent amount of LST.

lstAmount = LstTotalSupply / TotalSolAmount * stakingAmount

Unstake Flow ​

Any LsdToken holders are valid users, and can call unstake method to exchange SOL with LST.

Withdraw Flow ​

After waiting the unbonding period, users can get their rewards by calling withdraw method.

Balance Staking Pools ​

The default balancer is the project administrator, it is able to transfer to another account. Balancer can redelegate assets to another validator to keep the network in a healthy(well-balanced) status.

Relay Service ​

Due to the limitation of smart contract, it could not launch an execution. So StaFi Solana LSD Stack introduces Relay service. It will trigger StakeManager, at a certain interval, to collect and calculate users' reward, distribute it to the project and users.
