Understanding Liquidity Pools in Crypto

Liquidity pools are foundational in facilitating continuous, seamless trading on decentralised exchanges (DEXs) like ADEX.

Understanding Liquidity Pools in Crypto

What is a Liquidity Pool?

In the evolving world of decentralised finance (DeFi), liquidity pools are foundational in facilitating continuous, seamless trading on decentralised exchanges (DEXs) like ADEX. Simply put, a liquidity pool is a collection of crypto assets locked within a smart contract, providing liquidity for decentralised exchanges (DEXs) like ours. The beauty of liquidity pools is that they eliminate the need for a traditional order book system, where buyers and sellers are matched manually. Instead, liquidity pools allow for automatic trading between assets based on the available liquidity, ensuring smooth, continuous trading.

How Do Liquidity Pools Work?

Liquidity pools work by having liquidity providers (LPs) contribute two different tokens into the pool—let’s take the ETH/USDC pair as an example. Users provide equal values of both tokens to the pool, allowing others to swap between them. In return for their contribution, LPs receive liquidity pool (LP) tokens which represent their proportional share of both assets in the pool.

For example:

  • A liquidity provider deposits $1,000 worth of ETH and $1,000 worth of USDC into the ADEX ETH/USDC pool.
  • In return, they receive LP tokens that represent their proportional share of the pool.

When users trade ETH for USDC, the liquidity pool facilitates this transaction. The more liquidity in the pool, the more efficient and smooth the transaction, ensuring that there is always enough of each asset to trade, regardless of who the counterparties are.

What makes this process flow smoothly is the Automated Market Maker (AMM) model, which determines the price of assets using a constant product formula: x*y= k

Where:

  • x is the quantity of one token,
  • y is the quantity of the other token,
  • k is a constant, which remains unchanged unless liquidity is added or withdrawn.

This constant product model automatically adjusts prices based on the ratio of assets in the pool, ensuring fair and efficient pricing without the need for centralised intervention.

Who Moderates Liquidity Pools?

One of the beautiful aspects of DeFi is that liquidity pools on platforms like ADEX are autonomously managed by self-executing smart contracts. These smart contracts are programmed to handle the execution of trades, adjust pricing, and ensure the pool’s balance—all without human intervention. This trustless system is one of the key advantages of decentralised exchanges.This trustless, automated system is a key advantage of decentralized exchanges.

While smart contracts govern the technical aspects, liquidity providers still have a role to play. They can add or remove liquidity as they see fit. By contributing their tokens to the pool, they help maintain its liquidity, ensuring that the market remains fluid and operational. In return, liquidity providers are rewarded through trading fees, which brings us to the next point.

How Do Fees Work in Liquidity Pools?

Liquidity providers on ADEX are rewarded through fees generated from every trade made within the pool. Each time a swap is made—, say from ETH to USDC—, a small fee (typically 0.1% to 0.3%, though this can vary across different DEXs) is charged. These fees are collected and distributed proportionally among all liquidity providers based on their share of the pool.

For example:

  • If the total value of the pool is $1 million and an LP has provided $10,000 worth of liquidity, they hold 1% of the pool.
  • If $5,000 in trading fees are generated, that LP would earn 1% of the fees, or $50.

At ADEX,  we aim to offer competitive fee structures that not only rewards liquidity providers but also maintains a fair trading environment for all users. Different pools may have varying fee structures depending on the assets and their associated risk. For instance, assets that are more volatile may carry higher fees to incentivise LP participation.

Liquidity pools are a fundamental part of the decentralised ecosystem that enables smooth, trustless trading on platforms like ADEX. They are automated, governed by smart contracts, and reward liquidity providers with trading fees. However, as with any financial mechanism, it’s important to be aware of potential risks, including impermanent loss—the temporary loss of funds experienced when the price of tokens in the pool fluctuates.

Impermanent Loss

Liquidity providers may face a risk known as impermanent loss, which occurs when the price of the tokens in the pool changes significantly compared to their value at the time of deposit. This can result in the value of their assets in the pool being lower than if they had simply held the tokens outside of the pool. However, the loss is termed 'impermanent' because if the prices eventually return to their original levels, the loss is mitigated.

Conclusion

At ADEX, we’re focused on providing a secure, transparent, and rewarding liquidity pool system, designed to benefit both traders and liquidity providers alike. As DeFi evolves, liquidity pools will remain at the heart of this financial revolution, driving the next generation of secure, decentralised trading. Together with our partners we are already working to bring large and highly competitive liquidity pools to market. Watch this space.
