Chainstack

Build better with Aurora nodes​


Aurora Labs have always put the building and scaling of decentralized solutions through its infrastructure as a top priority. That has now become even more more accessible with the help of Chainstack - who brings reliable high-performance infrastructure to the table which makes the processes more easier, faster and much more secure.

Reliable Aurora mainnet and testnet infrastructure​

Chainstack makes sure you get access to robust and scalable infrastructure, ready for your Aurora journey, in a matter of minutes. We take away the burden of managing it so that you can instantly focus on building and exploring data on NEAR through Aurora.

Start fast with elastic Aurora RPC nodes​

Elastic Aurora RPC nodes* provide personal, and protected API endpoints you can immediately start using to interact with both NEAR networks through your Aurora RPC nodes, starting at $0 per month.\

  • Chainstack elastic Aurora RPC nodes
    • Unlimited requests, no rate limiting or throttling
    • Rapid deployment through Bolt
    • Secure HTTP

Aurora RPC archive nodes​

Get access to Aurora RPC archive nodes to query the entire history of the NEAR mainnet—starting at just $49 per month. And with Chainstack’s Bolt fast sync technology, you can deploy your own dedicated archive node in minutes instead of months.

Turbocharged sync​

With Chainstack’s Bolt technology users get fully synced dedicated Aurora RPC nodes in almost no time at all. By using up-to-date snapshots of the ledger, Chainstack spins up dedicated Aurora RPC nodes with the latest state—so it is possible to get a node ready same day rather than having to wait long sync times while spinning it from genesis block.

Dedicated nodes for dedicated users​

Chainstack’s dedicated nodes are a go-to for request-intensive workloads on NEAR through Aurora, including traders and multiple different DeFi projects.

  • Chainstack dedicated Aurora RPC nodes
    • Unlimited requests, no rate limiting or throttling
    • Rapid deployment through Bolt

Chainstack Marketplace​

Chainstack is designed to work hand-in-hand with the NEAR and Aurora ecosystem: tools, apps and services that you use every day to build your applications or amplify returns. They work closely with developers and the NEAR and Aurora community to ensure seamless integration for our end users.

module.exports = {
  solidity: "0.7.3",
  networks: {
    chainstack: {
        url: "ENDPOINT",
        accounts: ["PRIVATE_KEY"]
    },
   }
};

where

  • ENDPOINT — your node HTTPS or WSS endpoint.
