Everlend is a lending aggregator and optimizer. Get the best rates on your deposits and loans, always.

A general pool is an implementation of Solana pool program, which is responsible for storing users' liquidity and minting collateral tokens. There’s a general pool for every token supported by Everlend. When users interact with Everlend, they actually work with general pools, e.g. users' deposits and withdrawals are made via them.

The SDK allows interacting with Everlend general pools, specifically:

• getting general pools for tokens, e.g. there's a general pool for USDT, USDC etc.
• getting user's withdrawal requests
• preparing deposit transactions to a general pool
• preparing withdrawal request transactions from a general pool
• preparing withdrawal transactions from a general pool
• preparing transactions for initializing a mining account for a user to allow receiving liquidity mining rewards
• preparing transactions for claiming liquidity mining rewards
• preparing transactions for transferring deposits

It's still work in progress. In the future the SDK will be expanded with other useful features such as getting APYs for tokens etc.
