Aurora is a powerful blockchain platform built on the NEAR Protocol, designed to be fully compatible with Ethereum. It operates as a decentralized Layer 2 solution, enabling seamless integration of Web2 businesses into the Web3 ecosystem. Through innovations like Aurora Cloud, it offers a user-friendly environment for developers to deploy Ethereum-based applications without rewriting smart contracts. With low transaction fees, fast execution, and full support for Ethereum tools, Aurora provides an efficient and scalable solution for blockchain projects.
Key Takeaways
- Aurora is an EVM-compatible blockchain on the NEAR Protocol, allowing seamless Ethereum integration.
- The platform offers low, consistent transaction fees paid in ETH, with the added benefit of gasless transactions.
- Aurora supports multi-chain interoperability, enabling asset transfers and communication between Ethereum, NEAR, and other EVM networks.
What is Aurora?
Aurora is an advanced blockchain ecosystem compatible with Ethereum Virtual Machine (EVM), operating as a decentralized Layer 2 solution on the NEAR Protocol. It facilitates innovations like Aurora Cloud, a platform designed to help Web2 businesses transition smoothly into the Web3 space.
Aurora operates as an EVM through a smart contract on the NEAR Protocol, offering several unique advantages:
- Aurora ensures full compatibility with Ethereum, allowing developers to deploy applications directly on Aurora without needing to rewrite existing smart contracts. Only the RPC endpoint needs to be updated.
- Built on the NEAR Protocol, Aurora leverages one of the highest-performance third-generation Layer 1 protocols.
- Transaction fees in Aurora are consistent, paid in ETH, with a gas price of 0.07 GWei.
- The platform fully supports Ethereum ecosystem tools like MetaMask, Foundry, Truffle, Hardhat, and Remix.
- Aurora features protocol-level meta-transactions, offering benefits such as gasless transactions for end users.
How Aurora Works
Aurora’s architecture is based on a relayer system, which natively supports meta-transactions. This design enables users to interact with the system efficiently, as shown in the diagram below:
Source: Aurora
In this model, users pay transaction fees in ETH, while the RPC node settles the payment in NEAR tokens. This action triggers a corresponding NEAR transaction and calls the Aurora Engine contract to execute the transaction.
Interoperability of Aurora
Aurora’s interoperability is enhanced by its integration with the Rainbow Bridge, enabling seamless asset transfers between Ethereum, NEAR, and Aurora blockchains. Furthermore, Aurora is integrated with the LayerZero protocol, enabling cross-chain communication with over 40 EVM networks.
Additionally, Aurora supports the deployment of multiple EVM instances on NEAR, called Aurora Chains. These interconnected blockchains communicate via XCC (cross-contract calls) at the base layer. Each Aurora Chain can be configured with its ACLs (Access Control Lists) to manage which externally owned accounts (EOAs) can interact, deploy contracts, or perform XCC within that chain.
By using the XCC library, developers can connect Aurora-based contracts with native NEAR Blockchain contracts, and vice versa.
