Trader nodes

Trader nodes (aka Warp transactions) propagate your transactions through bloXroute — the industry leader in high speed transaction propagation and landing across high value networks, including Ethereum, Solana, BNB Smart Chain, Polygon.

With the Trader nodes setting on, your transactions will be distributed in either through the high-speed transaction relay network if it's an EVM network or to directly to the leader if it's Solana. This will make your transaction be available for the validators to pick up and include in the block much faster than with the regular propagation.

Why use with Chainstack

With Chainstack Trader nodes, you get the convenience of both worlds — reliable nodes for everything up to sending the transaction & the high speed of bloXroute for the transaction itself.

In other words, if you have a a bot running, switching your setup to a Chainstack Trader node is as easy as switching the endpoint in your code.

The way Chainstack Trader nodes work is all calls go through the Chainstack infrastructure, except for one — eth_sendRawTransaction for EVMs or sendTransaction for Solana — this call is always routed directly to bloXroute.

Normally, you'd face two challenging scenarios:

• Using bloXroute alone would require crafting your own transaction and using different node endpoints from providers, necessitating a custom setup.
• Relying solely on nodes would mean creating your own low-latency setup.

However, with Chainstack, everything is done for you. You can simply use one endpoint, streamlining the entire process.

Sample scenario

The use cases are numerous, but here's a sample one:

• Liquidity is deployed on a chain
• You get a signal on the deployed liquidity through third-party monitoring systems
• On the signal, your bot acts on the liquidity (e.g. does a purchase transaction) and the transaction is immediately propagated through the Chainstack trader node for any validator node to pick it up
• Once your transaction is committed by a validator to a block, you win the race thanks to the Chainstack trader node propagation

For best results and reduced latency, deploy a Trader node with Chainstack in the location nearest to your bot.

Availability

The Trader nodes feature is available starting from the Growth plan for the following protocols:

• Ethereum
• Solana
• BNB Smart Chain
• Polygon

There is a number of monthly allocated Trader node transactions included in the plan. Each extra transaction (not request, just the transaction) consumed is billed separately. For details, see Pricing.

Make sure you don't get strapped with the pay-as-you-go setting.

Usage

Under the hood, a Warp transaction is a transaction sent to your node with:

• EVM — eth_sendRawTransaction
• Solana — sendTransaction

For example, if you send your transaction with your MetaMask connected to a Chainstack node, the transaction will be sent using eth_sendRawTransaction.

With the Trader nodes setting on, only eth_sendRawTransaction on EVM networks or sendTransaction transactions are consumed as Warp transactions. Other requests to the node are consumed as regular requests.
