5 Blockchains With Deep Liquidity to Watch in 2025
When you’re interacting onchain, liquidity is everything. Whether executing swaps or trading perps, liquidity ensures that assets can be efficiently exchanged without significant price impact. More than just a metric denoting network health, deep liquidity is a hallmark of usability and ecosystem growth.
Through a combination of clever optimization, quality DeFi primitives, and incentive programs, the following chains have succeeded in becoming liquidity powerhouses that will shape the onchain landscape in 2025.
1. Ethereum: The Liquidity Giant
Ethereum remains the undisputed king of blockchain liquidity, retaining its position as the home of DeFi and the place where the largest onchain swaps are routinely made. With its first-mover advantage, Ethereum hosts some of the best DEXs and DeFi protocols including Uniswap and Curve, ensuring deep liquidity pools for trading a vast array of tokens.
The proliferation of Ethereum Layer 2 scaling solutions has further enhanced liquidity by reducing transaction costs and congestion, making it a hub for financial innovation and high-speed trading. While Ethereum mainnet transactions still cost more than on comparable L1s and L2s, the price comes with the provision of deep liquidity which makes all the difference to traders swapping with size.
2. EOS: A Dark Horse in Liquidity
EOS has emerged as a formidable contender in the quest for boundless onchain liquidity, driven by its evolving ecosystem and versatile range of DeFi protocols. Known for its high transaction throughput and low fees, EOS has successfully positioned itself as a reliable network for decentralized applications that allow traders to extract more value from every swap they make.
Recent upgrades and partnerships have bolstered EOS’s liquidity pools, attracting institutional players and retail investors alike. Its focus on scalability and efficiency, meanwhile, ensures that EOS can support the high-frequency transactions required by next-generation DEXs and perps markets. Protocols such as EOS REX and DeFiBox have been instrumental in driving this trend while growing the network’s rising TVL.
3. Avalanche: Liquidity Across Subnets
Avalanche has carved out a unique niche with its multi-chain architecture and subnet ecosystems, providing targeted liquidity solutions for specific use cases. By allowing projects to create their own customizable blockchains while still benefiting from Avalanche’s overarching infrastructure, the network fosters a highly liquid and interconnected ecosystem.
AVAX’s compatibility with Ethereum’s Virtual Machine (EVM) further amplifies its liquidity as users can seamlessly bridge assets between the two networks. This multi-pronged approach has made Avalanche a go-to solution for projects prioritizing efficient liquidity management.
4. Polygon: Ethereum’s Scaling Partner
Polygon continues to solidify its reputation as a leading Layer-2 scaling solution for Ethereum, delivering both speed and cost-efficiency. This scalability has translated into strong liquidity across its ecosystem, which hosts a growing number of DeFi protocols, gaming projects, and NFT marketplaces.
With strategic partnerships and integrations into major web2 platforms, Polygon has quietly evolved into a series of highly liquidity networks. Its ability to connect with Ethereum and other chains ensures that assets can flow freely, providing users with efficient trading opportunities, regardless of which Polygon chain they choose.
5. Arbitrum: A Rising Star in DeFi Liquidity
Arbitrum has evolved into the preeminent Ethereum Layer 2 solution thanks to its focus on low fees and high transaction speeds. Its adoption by leading DeFi projects such as GMX has led to the rapid growth of spot and perps liquidity pools, making it a favored choice for users seeking efficiency without sacrificing security.
Arbitrum’s ecosystem is steadily expanding, attracting new DEXes and lending protocols that prioritize liquidity optimization. As more projects deploy on Arbitrum, liquidity will improve further, with the network even rivaling Ethereum for some of the most popular trading pairs such as ETH and stables.
Making Onchain Liquidity Go Further
Strong liquidity is the lifeblood of blockchain ecosystems, enabling seamless trading and the smooth functioning of DeFi protocols. It reduces slippage, ensuring accurate pricing, and supports cross-chain finance by enabling fast and cost-effective transfers.
More than just a financial metric, liquidity is a reflection of a blockchain project’s usability, ecosystem maturity, and market confidence. All five of the projects highlighted here – Ethereum, EOS, Avalanche, Polygon, and Arbitrum – are leading the way for onchain liquidity, freeing users to focus on other concerns, such as chasing the next high-yield opportunity or 100x. When the liquidity’s there, everything else slots neatly into place.
