Staking Client

The StakingClient provides functionality for interacting with Steer Finance staking pools. It supports both single and dual reward staking pools.

Features

• Fetch available staking pools
• Stake and withdraw tokens
• Claim rewards
• Check earned rewards and balances
• Calculate APR for staking pools
• Support for both single and dual reward pools

Example Usage

// Initialize the staking client
const stakingClient = steerClient.staking;

// Get all staking pools
const pools = await stakingClient.getStakingPools();

// Get pools for a specific chain
const polygonPools = await stakingClient.getStakingPools(137); // Polygon chain ID

// Stake tokens
await stakingClient.stake({
  stakingPool: '0x...', // staking pool address
  amount: 1000000000000000000n // amount in wei
});

// Check earned rewards
const earned = await stakingClient.earned('0x...', '0x...'); // pool address, account address
console.log('Earned rewards:', earned.data);

// Calculate APR
const apr = stakingClient.calculateAPR(
  pool,
  rewardTokenPriceUSD,
  totalStakedUSD
);
