NEAR Chain Abstraction: Revolutionizing Multichain DEX and DeFi

In the ever-evolving landscape of blockchain technology, NEAR Protocol is charting a bold new course with its revolutionary approach to chain abstraction. While the crypto industry has witnessed significant growth and development, NEAR Protocol stands out by embracing both monolithic and modular aspects of blockchain technology, ultimately aiming to make blockchain infrastructure invisible to users and developers. In this article, we will explore what is Chain Abstraction, benefits and implications of NEAR’s Chain Abstraction and why it is a game-changer for the world of decentralized finance (DeFi).

What is NEAR Protocol?

NEAR Protocol is a blockchain platform that is at the forefront of revolutionizing the world of decentralized finance (DeFi) and multichain decentralized exchanges (DEX). It offers innovative solutions like Chain Abstraction, which is changing the way users interact with various blockchains.

Chain abstraction is a solution that simplifies key management, allowing smart contracts to decide the validity of transactions. However, NEAR takes this concept further by abstracting away the complexities of different chains altogether.

NEAR achieves this by leveraging account abstraction, modular data availability, cross-chain liquidity networks, and composable decentralized frontends for chain interoperability. With NEAR, users can manage multiple chains with just one account, simplifying the user experience significantly.

Why Do We Need Chain Abstraction?

The need for Chain Abstraction arises from the growing complexity of the blockchain space. As more chains and protocols emerge, users and developers face several challenges:

  1. Complexity: Managing multiple accounts, keys, and addresses on various chains is cumbersome for users.
  2. Security: Handling numerous private keys increases the risk of security breaches.
  3. Fragmentation: Each blockchain has its unique ecosystem, making it difficult for users to navigate and transact seamlessly across multiple chains.
  4. Bridge Contracts: Existing solutions often rely on bridge smart contracts, adding complexity and potential security risks to transactions between chains.

What is Chain Abstraction?

Chain abstraction is a concept that allows users to interact with multiple blockchains using a single account. Instead of creating separate accounts for each chain and managing multiple keys or seed phrases, users can create one account on a platform like NEAR and let it handle the keys and signing process for all supported chains. This concept simplifies user interactions with various blockchains and abstracts away the technical complexities.

Chain abstraction provides several benefits, including:

  • Single Account: Users only need one account to transact on multiple chains.
  • Simplified Key Management: Users no longer need to manage multiple keys or seed phrases for different chains.
  • Cross-Chain Transactions: Transactions between different chains can be executed seamlessly without the need for bridge smart contracts.
  • User-Friendly Experience: Users can log in using a simple email login, making blockchain interactions more accessible.

Chain abstraction is a game-changer for the blockchain space, and NEAR Protocol is leading the way in making this concept a reality.

How Do Near Accounts Work?

NEAR offers a unique account model that allows users to manage multiple keys within a single account with a human-readable name. This account system simplifies key management and enhances security.

NEAR accounts come in two types:

  1. FullAccess Keys: These keys provide admin access to an account, allowing users to create and delete keys, call smart contract functions, and even delete the entire account.
  2. FunctionCall Keys: FunctionCall keys are lightweight versions of FullAccess keys. They can call specific functions of a smart contract and have limitations on the functions they can access and the funds they can transfer. If a FunctionCall key is compromised, it can be replaced with a new one.

How Does NEAR Chain Abstraction Work?

NEAR’s chain abstraction enables users to sign and transact on multiple blockchains using their NEAR account. Here are the key components that make this possible:

1. OIDC Accounts Control NEAR Accounts

NEAR supports OIDC accounts that can control NEAR accounts, simplifying the login process by allowing users to transact on multiple chains with a simple email login.

2. Relay Servers Subsidize Gas Fees

Relay servers play a crucial role in subsidizing gas fees, ensuring that users can transact seamlessly without worrying about gas costs.

3. Accounts on NEAR Hold Multiple Keys

NEAR’s account aggregation feature allows users to store keys for multiple chains within a single NEAR account, streamlining key management.

4. Support for MPC Key Generation

NEAR uses multi-party computation (MPC) nodes for private key management. These nodes use threshold cryptography to hold parts of each key, ensuring security and trustlessness. This feature is called Chain Signatures.

5. Layer 2 Data Availability

NEAR’s Data Availability layer enables users to publish data on decentralized infrastructure at a fraction of the cost compared to other chains, enhancing data access and verification.

6. Frontend Component Hosting

The Blockchain Operating System (BOS) platform connects various components and libraries, allowing users to access website and blockchain data via the BOS API.

NEAR’s chain abstraction simplifies the process of transacting on multiple chains, enhances security, and provides a seamless user experience.

What are the Advantages of NEAR Chain Abstraction?

NEAR Protocol’s approach to Chain Abstraction brings several key advantages to the blockchain ecosystem:

1. Trustless Chain Abstraction

NEAR’s Chain Abstraction strives to make blockchain interactions seamless and trustless for users. By abstracting away the complexities of interacting with multiple blockchains, NEAR enables users to engage with decentralized applications (dApps) without worrying about the underlying infrastructure. This approach aligns with the vision of delivering better experiences to users, ultimately driving mainstream adoption of Web3.

2. Account Aggregation

One of the core components of NEAR’s Chain Abstraction is account aggregation, which eliminates the need for users to manage separate accounts for various Layer 1 (L1) and Layer 2 (L2) chains. NEAR is working on non-custodial accounts that enable cross-chain transactions, providing users with a unified experience across the entire Web3 ecosystem.

3. Decentralized Frontends

NEAR’s decentralized frontends offer developers a programmable environment to build applications that span multiple blockchains. These frontends abstract the underlying blockchain details from users, making it easier for them to navigate various dApps seamlessly. This approach is a significant step towards delivering smoother user experiences akin to those found on Web2.

Implications of NEAR’s Chain Abstraction on DeFi

NEAR’s Chain Abstraction has profound implications for the world of DeFi:

1. Streamlined Cross-Chain DeFi Activities

Users can exclusively interact with the NEAR chain while accessing DeFi applications streamlined via NEAR’s Blockchain Operating System (BOS) technology. This simplifies the entry point to cross-chain DeFi activities, such as swapping and lending, offering users a more user-friendly experience.

2. Secure Cross-Chain Transactions

NEAR’s Chain Abstraction enables DeFi applications on NEAR to prepare and sign transactions for cross-chain involvement. These transactions are securely managed by cross-chain relayers, which act as NEAR smart contracts with customizable rules. Users can participate in cross-chain DeFi activities without the need to manage separate wallets and accounts on different chains.

3. Enhanced Liquidity and Asset Movement

NEAR’s Chain Abstraction allows for the secure movement of liquidity and assets across various blockchains, including Ethereum, Ethereum layer 2 solutions, Bitcoin, Cosmos, and more. This interconnected DeFi ecosystem ensures that users can access liquidity from any network, promoting flexibility and efficient asset management.
