Yield, farming, providing liquidity
A swap pays the pool. Providing liquidity is how a person becomes part of that pool. A farm is often a second contract that pays an extra token for staying deposited. None of this is a rate you should expect to keep.
Liquidity on an Uniswap-style pool
On an EVM chain, the common pool holds two tokens. You deposit both, in the proportion the pool asks for, and you receive a claim on a share of the trading fees. The same shape shows up on Ethereum, BNB Chain, Polygon, PulseChain, and other EVM networks. The contract addresses are not the same just because the tickers match. Uniswap docs describe the pattern. The docs address currently stays on uniswap.org.
Where a Solana protocol offers a farm, it is the same idea on Solana’s programs: deposit, receive a share of fees or an extra token, and accept the risks below. Not every Solana token has a farm.
Impermanent loss
Impermanent loss is the gap between holding the two tokens in the pool and simply holding them in a wallet. If one token’s price moves far from the other, the pool rebalances by selling the one that rose and holding more of the one that fell. Fees can offset that gap. They do not have to. The name “impermanent” is hopeful. If you withdraw after the move, the gap is permanent.
Contract risk and fake sites
The pool is a program. A bug, an upgrade key, or a function that lets the deployer withdraw the reserves can empty it. Chapter 3 names those failure modes. A fake site copies the exchange name and asks for an approval. Bookmark the PulseX app and the Uniswap app rather than following a search result.
Where this project spends its time
At this point Blind Bit Boys finds PulseChain the most practical chain for screen-reader DeFi, using PulseX and Liberty Swap Finance. That is a judgment about this project’s work. It is not a claim that any one exchange is the only one a screen reader can operate.
