Warp transactions

Trader Nodes are extremely useful when used with Warp transactions on Solana, Ethereum, BNB Smart Chain.
Trader Nodes are available starting from the paid plans.

​
Modes

For Trader Nodes deployed on the most of public chains, Chainstack supports the following modes:
  • Full — a node that stores full blockchain data. However, it has limitations to how many blocks are available for querying.
  • Archive — a node that stores full blockchain data and an archive of historical states, which makes it possible to query any block since the chain genesis.

​
Mode and mempool availability by region

Trader Nodes are bound to a single region, and the modes on offer differ from region to region. Because the txpool_* methods need the archive mode, a region that offers only the full mode gives you no pool inspection — though subscribing to pending transactions still works there. On Ethereum Mainnet, for example, Trader Nodes are archive in London (lon1) and Ashburn (ash1), and full mode only in Singapore (sgp1). Check Available clouds, regions, & locations for the modes in your region, and What gives you mempool access for the rule itself. If you need txpool_* in a region that offers only the full mode, deploy a Dedicated Node there instead and ask for it — a Dedicated Node can serve txpool_* in either mode.

​
Warp transactions

Warp transactions propagate and land your transactions at the fastest speed possible. They are now a node add-on you install on Trader and Global Nodes from the node’s Add-ons tab, rather than a deployment-time option.

​
Dedicated gateways

A dedicated gateway is one of the Trader Node customization features that is available on the Enterprise plan. Dedicated gateways process connections and traffic exclusively for a specific customer, avoiding potential issues from handling multiple customers’ workload. This ensures a stable and reliable connection while reducing the likelihood of connection errors.
