The NEAR Protocol has rapidly emerged as a scalable, developer-friendly blockchain platform that supports high-performance decentralized applications (dApps). With its unique sharding architecture and focus on user experience, NEAR enables seamless cross-chain interoperability, low transaction fees, and fast finality. As the ecosystem grows, several native applications have become central to its DeFi, NFT, and cross-chain infrastructure.
In this article, we explore five key native applications shaping the NEAR ecosystem—each playing a vital role in expanding accessibility, functionality, and innovation across chains.
Rainbow Bridge: Connecting Ethereum, NEAR, and Aurora
At the heart of NEAR’s interoperability is the Rainbow Bridge, the official cross-chain bridge developed by the NEAR team. It enables secure asset transfers between Ethereum, NEAR, and the Aurora network.
When users transfer ERC-20 tokens from Ethereum to NEAR or Aurora, those assets are represented with an "n" prefix—such as nETH for bridged Ether. This naming convention helps distinguish bridged assets within the NEAR ecosystem. Conversely, wrapped assets on the Aurora network use a "w" prefix; for example, wNEAR represents NEAR tokens moved from the main NEAR chain to Aurora via the bridge.

Transferring assets from Ethereum to NEAR or Aurora requires just one transaction and typically completes in under 10 minutes. However, withdrawals back to Ethereum involve two steps: first moving assets from NEAR to Aurora, then from Aurora to Ethereum. Due to Ethereum's finality requirements, this process can take up to 16 hours. Additionally, gas costs depend on Ethereum network congestion—ranging from $10 to $50—and transactions cannot be canceled once initiated. Because of these delays and fees, Rainbow Bridge is best suited for larger transfers rather than microtransactions.
Aurora Network: Bridging Ethereum’s Ecosystem to NEAR
Aurora is a high-performance Ethereum Virtual Machine (EVM) built on top of the NEAR Protocol. Functioning as a Layer 2 scaling solution, Aurora allows developers and users to interact with Ethereum-compatible smart contracts at significantly lower costs.
Unlike other EVM-compatible chains that require their native tokens for gas fees (like MATIC on Polygon), Aurora uses ETH as its primary gas currency. This means users don’t need to acquire a new token to participate—they can use their existing ETH balance directly. Currently, average transaction fees on Aurora are close to 0 ETH, compared to ~0.08 ETH per transaction on Ethereum mainnet.
Aurora leverages NEAR’s sharding technology to enable parallel transaction processing, eliminating the bottleneck of having every node validate every transaction. This results in faster throughput and improved scalability.
Originally part of the NEAR ecosystem, Aurora became an independent project in July 2021 but maintains strong collaboration with the NEAR Foundation. Today, it serves as a crucial bridge between Ethereum and NEAR ecosystems—allowing developers to deploy Solidity-based dApps seamlessly while accessing both user bases.
As more projects build on Aurora, it strengthens NEAR’s position as a truly interoperable blockchain platform.
Ref Finance: The Leading DEX on NEAR
Ref Finance is the first automated market maker (AMM) decentralized exchange on the NEAR blockchain and currently the most active DeFi protocol in the ecosystem. According to data from NEAR Explorer, Ref Finance saw nearly 370,000 contract interactions over a recent 14-day period—highlighting its widespread adoption.
Ref Finance supports swapping, liquidity provisioning, and token farming for various native tokens across the NEAR ecosystem. Its native utility token, REF, has a total supply of 100 million and is used for governance, staking rewards, and protocol incentives.
While currently focused on decentralized trading, Ref Finance aims to evolve into a full-featured DeFi hub offering lending, borrowing, and even asset issuance capabilities. This expansion would solidify its role as a core financial infrastructure component within the NEAR ecosystem.
With an intuitive interface and deep integration with popular NEAR wallets like Sender Wallet and Ledger, Ref Finance lowers the barrier to entry for new users exploring DeFi on NEAR.

Trisolaris: The Premier DEX on Aurora
While Ref Finance dominates on the NEAR mainnet, Trisolaris holds the crown as the leading decentralized exchange on the Aurora network. As the first DEX deployed on Aurora, Trisolaris provides seamless trading for all ERC-20 compatible tokens.
Users can bring assets from Ethereum via the Rainbow Bridge or transfer NEAR-native tokens into Aurora to trade on Trisolaris. This flexibility makes it a go-to destination for users seeking exposure to both ecosystems without leaving a single interface.
Trisolaris emphasizes capital efficiency and low slippage through concentrated liquidity pools—similar to Uniswap V3—allowing liquidity providers to earn higher yields within defined price ranges.
As Aurora continues to grow its own application ecosystem, Trisolaris plays a pivotal role in enabling decentralized liquidity and trading activity.
Paras: An NFT Platform Focused on Story-Driven IP
Among the growing number of NFT marketplaces, Paras stands out by focusing on story-rich digital collectibles and intellectual property (IP) development.
Built natively on the NEAR blockchain, Paras allows artists and creators to mint and sell digital art as NFTs. But unlike platforms centered around single-image profile pictures (PFPs), Paras encourages creators to build narrative-driven series—think episodic comics, animated stories, or evolving character universes.
This emphasis on storytelling fosters deeper engagement between creators and collectors. Instead of isolated artworks, users collect pieces of a larger universe, increasing long-term value and community involvement.
To access Paras, users connect their NEAR wallets and make purchases using NEAR tokens. The low-cost and fast transaction environment of NEAR makes it ideal for frequent microtransactions often seen in NFT collecting.
As interest in digital storytelling and creator economies grows, Paras is well-positioned to become a leading platform for next-generation NFT experiences.
Frequently Asked Questions (FAQ)
Q: Can I use ETH to pay gas fees on NEAR?
A: Not directly on the NEAR mainnet, but yes on the Aurora network—which uses ETH as its native gas token.
Q: How long does it take to withdraw assets from NEAR back to Ethereum?
A: Up to 16 hours due to security validation periods when using Rainbow Bridge.
Q: Do I need NEAR tokens to use applications on Aurora?
A: No—you can use ETH for gas and interact with dApps without holding NEAR.
Q: What makes Paras different from other NFT marketplaces?
A: It emphasizes serialized, story-based collections rather than standalone images or PFPs.
Q: Is Trisolaris compatible with Ethereum wallets?
A: Yes—since it runs on Aurora (an EVM chain), you can connect MetaMask and other Ethereum wallets directly.
Q: Can I stake REF tokens on Ref Finance?
A: Yes—REF holders can stake tokens to earn rewards and participate in governance decisions.
