A decentralized exchange (DEX) enables users to trade cryptocurrency without dealing with a middleman, thus altering the manner in which users buy and sell cryptocurrency. DEXs like traditional exchanges, function on blockchain technology and focus on user control, transparency, and security. It brings a new challenge for adoption: DEX liquidity issue. If there is no sufficient liquidity trading would be costly, inefficient, and frustrating for users. In this blog, we'll cover what DEX liquidity is, attempting to explain why it is a challenge and how we can tackle it practically while keeping it informative and easy to navigate.
Liquidity indicates how easily you can purchase or sell an asset without affecting its price significantly. DEX liquidity denotes the balance of all assets in a trading pair that allow users to execute trades quickly at a stable price. Higher liquidity is accompanied with tighter spreads or the difference between buying and selling prices and low slippage while lower liquidity results in more volatile prices along with higher trading cost.
Market makers or the exchange's own funds, usually provide liquidity on centralized exchanges. However, DEXs depend on users providing a decentralized pooled collection of assets, often using automated market makers (AMMs). In order to have strong DEX liquidity, these pools need constant user contributions, which introduces challenges.
In comparison to centralized exchanges, DEXs have different challenges when it comes to liquidity. Let's go over the primary concerns:
The DeFi ecosystem contains an immense number of DEXs, including Uniswap, SushiSwap, and PancakeSwap. In addition, these platforms have their own liquidity pools, resulting in asset splitting across different ecosystems. This makes it difficult for any single DEX to provide sufficient trading liquidity for specific pairs as trading liquidity. For instance, when trying to swap out lesser-known tokens, you may encounter one DEX with shallow pools that result in significant slippage and others that do not have pools at all.
Liquidity providers who pay trading fees do so because they LP to put assets into pools. These pools are essentially assets used for trading in decentralized exchanges. LPs do ensure an income, however, it is not always lucrative. Providing liquidity comes at a cost, LPs must contend with risks like impermanent loss where the value of assets they deposited changes unfavorably compared to the market. If rewards don't compensate adequately for these risks, fewer people would participate leading to drained DEX liquidity.
High volume tokens like ETH or USDC easily maintain liquidity owing to a significant number of traders and LPs. Lesser known or newer tokens tend to struggle. Due to a lack of adequate trading volume, the fees paid to LPs becomes too low to justify participation. This leads to a negative cycle: poor DEX liquidity results in poor trading environments further discouraging users which, in turn, lowers volume.
Ethereum hosts many DEXs, but the high cost of gas not only affects LP's profits, but also traders. Higher transaction costs, result in a drop in DEX liquidity. Although layer 2 solutions and other blockchains like Binance Smart Chain or Solana have gained traction, not all DEXs have fully adopted them, stunting their growth and ability to scale and maintain liquidity.
The volatility of cryptocurrency markets is well-known. Sudden price fluctuations may affect liquidity pools, particularly for AMMs that depend on specific fixed ratios of assets. LPs may withdraw funds during extreme market events in order to mitigate potential losses. This reduces DEX liquidity precisely at the time when it is most critical.
Low liquidity creates inconvenience for traders, but does not end there. The whole DEX ecosystem suffers as well. Here's how:
● Increased Cost for Users: Low DEX liquidity leads to wider spreads and increased slippage which makes trading more expensive. Users, particularly large volume traders, may be deterred.
● Poor User Experience: Users becoming frustrated due to delays, failed trades, or encountering unexpected changing prices are likely to switch to centralized alternatives.
● Reduced Trust: The perception of a DEX with thin liquidity is unreliable leading to damage to its reputation and growth for years to come.
● Limited Token Adoption: New projects depend on DEXs for token distribution. These tokens become difficult to gain traction if there is low liquidity.
The DeFi community, however, is stepping up to address these challenges. Below are best practices designed to improve DEX liquidity and facilitate easier trading.
Offering better incentives can attract LPs. Many platforms provide governance tokens on top of trading fees. For example, Uniswap gives out UNI and PancakeSwap gives out CAKE. These tokens enable LPs to benefit from the platform's growth which motivates them to participate for the long term. Some DEXs are now trying out dynamic fee models where LPs get paid more when liquidity with the DEX is low, to balance supply and demand.
Nonetheless, sustainability is crucial. Incentivizing too much without balance, especially in the form of tokens, can lead to issues like dumping or inflation. Immediately rewarding DEX LPs with too many advantages tends to set up the DEX for failure in the future.
Liquidity aggregation uses resources from various DEXs/pools to construct a single trading interface. 1inch and Kyber Network are examples of protocols that aggregate trades from different platforms to ensure the best prices and deepest liquidity. Such access helps improve the DEX liquidity available to users. Also, aggregators provide broader networks without the need for every platform to maintain huge pools independently.
Aggregation decreases fragmentation and improves overall market efficiency while making it easier for traders to access low-demand tokens.
Many DEXs are looking into layer-2 scaling solutions like Optimism, Arbitrum, or Polygon due to high gas fees on Ethereum. These platforms enable transactions to be processed off the main Ethereum chain, which increases security and lowers costs. Having cheaper transactions increases the trading activity and liquidity supply, which improves DEX liquidity.
Cross-chain bridges are also revolutionary. DEXs can access liquidity from various ecosystems by bridging different chains such as Ethereum, Solana, and Avalanche together. For example, it allows a DEX to enable users to trade Solana based tokens against Ethereum based assets, thus pooling liquidity to deepen DEX liquidity.
Default AMMs to balance liquidity pools utilize simple formulas, but there are newer models that are far more effective. LPs are able to allocate capital to specific price ranges where trading is most active, this is called concentrated liquidity which was pioneered by Uniswap V3. This improves capital efficiency which means less funds are required to achieve significant DEX liquidity. Others, like Curve, focus on pairs of stablecoins thus reducing impermanent loss and attracting more LPs due to low volatility.
By customizing liquidity provision strategies within AMMs to cater specific tokens, DEXs can sustain healthy liquidity for even thinly traded tokens.
Liquidity bootstrapping 'LBPs' offer a solution for less popular tokens or coins that are having issues with DEX liquidity. LBPs permit projects to slowly distribute tokens while simultaneously building liquidity over a specific duration. LBPs use dynamic pricing to capture early traders and LPs, thus laying the groundwork for sustainable DEX liquidity. Balancer and other platforms have adopted this model to assist new projects in gaining exposure.
Active community members can incentivize DEX liquidity through participation, thus serving as a strong driver. Token holders can vote on governance decisions in dapps providing incentive and pool strategy to engage users. Social media, AMAs, educational content, and more foster liquidity and trading by building trust. As an example, SushiSwap has been able to compete with bigger players because of the community-driven approach they adopted despite limited resources.
LPs face a large challenge from impermanence loss. This problem exists because many DEXs do not provide loss protection methods. A response to this problem is providing some form of loss gap coverage. Bancor is one of many platforms that offer pro single side LP where users deposit only one asset lowering the price swing exposure. Other put loss coverage, insurance pools, or hedging strategies to offset losses making providing liquidity less risky while increasing DEX liquidity.
Fiat currencies can be easily converted into stable coins such as USDT, USDC, and DAI which are widely used in the DeFi market. DEXs that have stable coin pairs usually enjoy higher DEX liquidity as they attract cautious traders and LPs. The inclusion of fiat on-ramps also brings additional participants as users are able to purchase crypto directly using traditional money, thus enhancing trading volume and liquidity.
Solutions for DEX liquidity will keep on emerging alongside the evolution of DeFi. New technologies like zero-knowledge proofs could further reduce the cost of transaction, while AI-driven algorithms can optimize liquidity reallocation to be done in real-time. Clear regulations can also entice institutional players to provide liquidity which could help deepen the gap between DeFi and traditional finance.
Despite this, the primary obstacle remains balance: decentralised exchanges need to satisfy the demands of traders, LPs, and token projects simultaneously manage to achieve decentralization. DEXs can achieve this goal and let liquidity flourish by seamlessly automating decentralized trading akin to centralized trading by marrying community-in trusted innovations.
Like with any exchange, liquidity is of utmost importance for DEXs. Their challenges of fragmentation, impermanent loss, and high fees are hurdles to overcome. From smarter AMMs, to cross-chain bridges, and even community incentivization; DEXs have tools that can help improve DEX liquidity. These solutions will allow them to realize the full potential of decentralized trading, which is giving users fast, cheap, and reliable markets.
If you're a trader or liquidity provider, look for DEXs that offer these kinds of solutions. Your participation shapes the future of DeFi, one pool at a time.
