Node customizations

On the Enterprise subscription, you can order a custom node set up.

The readily available customizations:

• txpool.pricebump — The minimum bump in the transaction fee to replace a pending transaction with the same nonce. The default value is 10%. For EVM-based protocols
• rpc.txfeecap — A cap on the transaction fee. The default value is 100 base currency*. For EVM-based protocols.
• rpc.gascap — A cap on the gas that can be used to run eth_call and eth_estimateGas. The default value is 0.5 base currency*. 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.
• Dedicated gateway — A dedicated gateway for the endpoints to the elastic nodes. A dedicated gateway allows for a dedicated connection to the node and eliminates some of the limitations like the need to reconnect.
• Scaling up node resources—storage, CPU, RAM.
• Tailored load balancing — A dedicated gateway that balances the requests 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 to communicate for your application and the node over Internet and drastically reduces the latency and increases the speed.

Contact support for customizations — for the mentioned customization or for any other customization that you need.

*Base currency is the native token of the protocol:

• For Ethereum, the base currency is ETH.
• For Polygon, the base currency is MATIC.
• For BNB Smart Chain, the base currency is BNB.
• For Avalanche, the base currency is AVAX.
• For Fantom, the base currency is FTM.
• For Harmony, the base currency is ONE.
