Features availability

Warp transactions

Warp transactions are available starting from the Growth plan for the following protocols:

• Ethereum
• Polygon
• BNB Smart Chain

There is a number of monthly allocated Warp transactions included in the plan. Each extra Warp transaction consumed is billed separately in USD. For details, see Pricing.

Debug and trace APIs

Debug and trace APIs are available starting from the Growth plan for the following protocols:

• Ethereum
• Polygon
• BNB Smart Chain
• Base
• Avalanche
• Arbitrum
• zkSync Era∎
• Optimism
• Ronin
• Gnosis Chain
• Fantom
• Harmony

Mempool

See Mempool configurations.

Subgraphs

Elastic archive

Elastic archive nodes of Chainstack Subgraphs cost $0.1/h for computing and our subscription plans include the following:

• Developer — 1 subgraph
• Growth — 10 subgraphs
• Business — 20 subgraphs
• Enterprise — unlimited subgraphs

Dedicated indexer

A dedicated indexer is available on the Enterprise plan. A dedicated indexer can deploy multiple subgraphs across different chains.

The available dedicated indexer types and their hardware requirements are:

Private networking

Private networking is available on the Enterprise plan.

Private networking is an exclusive functionality available to nodes hosted on AWS. It leverages the advanced technology of AWS PrivateLink to achieve a significant reduction in latency.

To set up private networking for your node, your DApp must be located in the same region as your AWS node, e.g. us-east-1. When using private networking, node interaction will be performed through AWS internal infrastructure and will not be exposed to the public internet. This approach enhances security measures and minimizes processing time, delivering optimal performance.

Appchains

Appchains are available on the Enterprise plan.

Appchains, or application chains, are a solution where each application functions as its own specialized blockchain providing a strong foundation with improved security and scalability. Transactions on appchains are processed out of their individual mempool, and gas fees for transactions can be as low as the developer decides them to be. These two factors enable appchains with the ability to process transactions much faster than any L1 can.

Node customization

Node customization is available on the Enterprise plan for dedicated nodes. Below you can find the current customizations that can be used for your node. Feel free to check with us for any additional customization that's not on the list.

Transaction settings

• txpool.pricebump — the minimum increase in transaction fee required to replace a pending transaction with the same nonce. The default value is 10%. Applicable for EVM-based protocols.
• rpc.txfeecap — a limit on the transaction fee. The default value is 100 base currency. Applicable for EVM-based protocols.

  📘

  Base currency

  Base currency is the native token of a protocol.

• rpc.gascap — a limit on the gas that can be used to run eth_call and eth_estimateGas. The default value is 0.5 base currency. Applicable for EVM-based protocols.
• txlookuplimit — the maximum number of blocks whose transaction indices are reserved. By default, for Ethereum and Polygon, the number is 2350000.

Node and network customizations

• Dedicated gateway — provides a dedicated connection to the node, eliminating some limitations, such as the need to reconnect.
• Scaling node resources — options to scale up node resources like storage, CPU, and RAM.
• Tailored load balancing — a dedicated gateway that balances the request load between multiple dedicated nodes.
• Private networking — connect your application running on AWS to a Chainstack node running on AWS through a private network. This eliminates the need for your application and the node to communicate over the internet, reducing latency and increasing speed.
• Indexing for Bitcoin nodes
