​
Trader node transactions

Trader node transactions (ex. Warp transactions) are available starting from the paid plans for the following protocols:
  • Ethereum
  • Solana
  • BNB Smart Chain

​
Debug and trace APIs

Debug and trace APIs are available starting from the paid plan. For per protocol availability, see Available clouds, regions, and locations.

​
Mempool

See Mempool configurations.

​
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.

​
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, as these are just examples.

​
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.
  • 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.
Base currency is the native token of a protocol.

​
Node and network customizations

  • Dedicated gateway — provides a dedicated connection to the node, eliminating some limitations, such as the need to reconnect.
  • Custom EVM tracers — We can enable custom JavaScript tracers for your dedicated EVM node.
  • 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.
  • Hyperliquid system transactions — enable system transaction visibility for tracking transfers between HyperCore and HyperEVM. Available on Dedicated Nodes. See Hyperliquid node configuration for details.
For any customizations not listed here, contact Chainstack support. We are always happy to explore your case and help you.
