Introduction

Asternodes is a Blockchain-as-a-Service that provides access to 15+ blockchains via such APIs as REST, WS, and JSON-RPC. You can find the full list of available nodes here.

The service allows developers, wallets, exchanges, blockchain explorers, and other DApplications to effortlessly connect to Web3 instead of deploying and maintaining nodes in-house. If you have any questions, please feel free to contact us.

Blockchain List & Docs

Here you can find the complete list of blockchains available on Asternodes with corresponding API methods. We've collected resources with comprehensive information on related topics.
NB: by default, Asternodes provides access to mainnet; if you wish to connect to testnet, please leave your request here.

Getting started

Login and password

No need to create any accounts — get the keys directly. To use Asternodes' service, perform the following steps:

1. Choose a plan that suits you most
2. Fill out the form
3. Receive payment information (for all plans except for the free one) and follow the instructions

After that, your login and password will arrive in your mailbox. Beyond the credentials, you'll receive the list of client URLs (cURLs) to access the networks you choose. The cURL’s format:
http://--.asternodes.io/
NB: The cURLs are blockchain-specific. That is, if you need to access Ethereum, BSC, and Solana, you’ll be provided three different cURLs. At the same time, your login and password would be the same on each endpoint.

Authentification

The authentication procedure would be the same for each blockchain. You can check your credentials via terminal or via browser. The following instruction is applicable for the browser option. Please note that sometimes browsers download JSON-responses on your device in a separate file — that’s a standard behavior.

After you receive your cURL in “http://--.asternodes.io/” format, click on it to open a window. Imagine that we access Ethereum nodes.

1. The following page will appear:
   
2. Enter your login into the “Username”, and password into the “Password” fields.
3. If you’ve done everything correctly, you will see a blank page. That means that now you can make requests to the Ethereum blockchain
   
4. Leave the browser page. To start making requests, you need to interact with cURL via your terminal. Your request should include a string in the following format :. For example:
   
   curl -X POST -u login:password -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' https://eth--login.asternodes.io
5. Find the example of requests here or visit the official website of the blockchain of interest.

Special Cases

Some blockchains, rather than just a blank page, may return text messages. All of the indicated below is a standard behavior of a nodes:

Algorand
Avalanche
Monero

NEO3

Polkadot

Solana

TRON

VeChain


MetaMask Integration

One way to keep your MetaMask operations private is performing them via Asternodes. Here you can find a detailed guide on how to add Asternodes RPC endpoint to MetaMask.

Kindly note that MetaMask is a third party application, not associated with Asternodes. Therefore, we can not guarantee its safety and latency.

NB! Asternodes respects your privacy and does not store address data.

1. Receive Asternodes’ login and password.
   Start with a 2-weeks free trial or with an upgraded plan.
   
2. Go to MetaMask and choose “Add network”.
   Sign up or log into your MetaMask account. Click on the network dropdown list.
   
   Click on the “Add network” option.
   
   
   The information that you need to enter manually is
   • Network name
   • Asternodes RPC URL
   • ChainID
   • Currency symbol
   • Block Explorer URL (optional)

   Network	Default RPC cURL	ChainID	Currency symbol	Block Explorer URL
   Avalanche Network C-Chain	https://avalanche--login.asternodes.io/ext/bc/X	0xa86a	AVAX	https://avascan.info/blockchain/c/
   Binance Smart Chain Mainnet	https://bsc--login.asternodes.io/	56	BNB	https://bscscan.com/
   Callisto Mainnet	https://clo--login.asternodes.io/	820	CLO	https://callisto.network
   Ethereum Mainnet	https://eth--login.asternodes.io/	1	ETH	https://etherscan.io/
   Ethreum Classic	https://etc--login.asternodes.io/	61	ETC	https://blockscout.com/etc/mainnet/
   EthereumPoW Mainnet	https://ethpow--login.asternodes.io/	10001	ETHW	https://mainnet.ethwscan.com
   Polygon Mainnet	https://polygon--login.asternodes.io/	137	MATIC	https://polygonscan.com/

   Do not forget to replace “login” in the cURL with your specific information provided by Asternodes.
   
3. Fill in the network information.
   After you enter cURL, ChainID and currency symbol, a window with Basic Authentication will appear. Enter the data you’ve received from Asternodes.
   
   That’s it!
   

API Methods
Overall, Asternodes supports JSON-RPC, REST, and WebSocket API interfaces. Each node supports its specific set of methods, elaborated in this section.
NB! To apply WebSocket, you need to use the cURLs that contain the “ws” identifier in its body. For example, a standard Ethereum cURL under JSON-RPC method looks like this: https://eth--login.asternodes.io/. In contrast, the WebSocket cURL is wss://ethws--login.asternodes.io/.

Asternodes supports the following JSON-RPC modules for Ethereum-like blockchains:

1. Avalanche: eth, net, web3
2. Ethereum: net, web3, eth, debug, txpool
3. Ethereum Classic: net, web3, eth, debug, txpool
4. EthereumPoW: net, web3, eth, debug, txpool
5. Binance Smart Chain: net, web3, eth, debug, txpool
6. Callisto: net, web3, eth, shh, txpool
7. Polygon: net, web3, eth, txpool, bor

Batch calls
Our nodes support the multicall (batch) requests on Ethereum-like blockchains: Avalanche, Binance Smart Chain, Callisto, Ethereum, Ethereum Classic, EthereumPoW, and Polygon. Each batch is counted as one request within your RPM rate. That is, if a batch includes 10 API calls, it is treated as a single request anyway.

The logic behind multicall requests is similar to single API calls. The only difference is the presence of additional arrays that contain several individual API calls. Consider the example with eth_blockNumber request on Ethereum.
Individual eth_blockNumber request:
Batch eth_blockNumber request

List All Effects
Effects represent specific changes that occur in the ledger as a result of successful operations, but are not necessarily directly reflected in the ledger or history, as transactions and operations are. This endpoint lists all effects and can be used in streaming mode. Streaming mode allows you to listen for new effects as they are added to the Stellar ledger.

Request parameter

order (optional) A designation of the order in which records should appear. Options include asc (ascending) or desc (descending). If this argument isn’t set, it defaults to asc.
limit (optional) The maximum number of records returned. The limit can range from 1 to 200 - an upper limit that is hardcoded in Horizon for performance reasons. If this argument isn’t designated, it defaults to 10.
Example Request

List All Offers
Offers are statements about how much of an asset an account wants to buy or sell. This endpoint lists all currently open offers and can be used in streaming mode.

FAQ
Can I request a rate that is higher than 20,000 requests per minute?
Yes. We’d be happy to discuss it with you via website form, Telegram, or email (team@asternodes.io).

Do you limit the number of simultaneous connections from a single IP?
By default, the maximum IP flow is 100. Please contact us via website form, Telegram, or email (team@asternodes.io) to request a higher limit.

Do you plan to extend your current list of supported blockchains?
Yes. Asternodes adds new blockchains every month.

What shall I do if there are some urgent issues regarding the stability of a node?
Alongside with cURLs and credentials, you are given access to a special email address that accepts reports on emergency situations. Also, feel free to contact us via Telegram, which is constantly monitored.

Why does my archive node perform worse than a public full node of a blockchain?
It is incorrect to compare the productivity of an archive node with a full one. For example, BSC erigon works slower than the public full nodes of these blockchain by default, though it provides you with information since genesis. If you need maximum productivity, we’re ready to supply you with a full node of BSC instead.
