CrossChain Swap API

Overview

The Native Bridge API enables seamless cross-chain token bridging and swapping across multiple blockchain networks, utilising the same reliable Native Swap Engine and Native Credit Pool for superb pricing and performance.

Endpoints

Our API enables users to fetch cross-chain bridge quotes, generate transaction data for executing on-chain bridge transactions via Native's infrastructure, and manage their bridging lifecycle. The intelligent routing algorithm ensures users receive the best possible market prices for optimal cross-chain trading outcomes.

• Indicative quote: Use GET /bridge/indicative-quote to obtain fast, indicative quotes for bridging tokens across chains. This endpoint provides pricing information without generating calldata, making it ideal for displaying estimated rates to users before they commit to a transaction.

• Firm quote: Use GET /bridge/firm-quote to obtain executable transaction data necessary to initiate cross-chain bridge transactions. This endpoint returns the complete calldata, target contract address, and all necessary parameters for executing the bridge transaction on the source chain.

• Transaction status: Use GET /bridge/tx-status to check the current status of a bridging transaction. This endpoint allows you to monitor the progress of your bridge request from initiation through completion, refund, or claim.

• Transaction history: Use GET /bridge/tx-history to retrieve a paginated list of all bridge transactions for a specific user address. This endpoint enables users to view their complete bridging history across different chains.

• Refund: Use GET /bridge/refund to request a refund for a bridging transaction that has failed or cannot be completed. This endpoint initiates the refund process for tokens that were locked but not successfully bridged.
