Description
This pull request introduces two key enhancements to the Lido SDK:
Transaction Simulation : Adds a simulateTransaction method that allows users to simulate transactions before executing them on-chain. This ensures transaction success, estimates gas usage, and prevents unnecessary gas costs.
Real-Time Staking Rewards Estimation : Implements methods (getCurrentAPR, estimateRewards, and getHistoricalRewards) to fetch the current APR from the Lido protocol's StakingRouter contract, estimate future rewards based on user balance and time period, and retrieve historical reward distributions via Lido's subgraph API.
These features improve usability by providing users with insights into transaction behavior and staking performance while ensuring compatibility with the latest Lido protocol updates.
