Supported Networks

Definitive's API supports trading and position management across multiple blockchain networks. You can use the same API interface to interact with any of our supported networks.

Using Networks in API Requests

When making API requests, specify the desired network using the chain parameter. For example, when requesting a quote:

const quoteRequest = {
  type: "market",
  chain: "base", // Specify the desired network
  targetAsset: "0xA12B34C56D78E90F12AB34CD56EF78A901BC234D",
  contraAsset: "0xF98765C43210D78E90AB56CD12EF34A908BC765D",
  qty: "1000.00",
  orderSide: "sell",
  slippageTolerance: "0.01",
  maxPriceImpact: "0.05",
};

Cross-Chain Trading

Market orders can swap across any two supported networks in a single request — including between EVM networks and Solana. Set chain to the target asset's network and contraChain to the contra asset's network:

const crossChainQuoteRequest = {
  type: "market",
  chain: "arbitrum", // network of targetAsset
  contraChain: "base", // network of contraAsset
  targetAsset: "0xaf88d065e77c8cC2239327C5EDb3A432268e5831",
  contraAsset: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
  qty: "5",
  orderSide: "buy",
  slippageTolerance: "0.05",
  maxPriceImpact: "0.05",
};

Cross-chain is supported for market orders only — see Cross-Chain Market Order
Both networks need an active trading vault; the first cross-chain quote on a new network may return a 422 while the vault initializes — retry shortly
To move an asset between networks without swapping, use Bridge

Network-Specific Considerations

Each network has its own set of supported assets and trading pairs
Gas costs and transaction speeds vary between networks
Some advanced order types may have limited availability on certain networks
