API

The following APIs are provided for developers who need to implement the bridge function. If you want to integrate into the Poly bridge, please get in touch with Poly team via for more support.

Poly Bridge APIs:

  • Get cross-chain fee.
  • Get cross-chain transaction status.
  • Get transaction history.
  • Get basic token information.
  • Get token mapping relationship between different chains.
  • Get the expected cross-chain duration.

Get cross chain fee

This API returns a transaction fee charged on the source chain in a cross-chain transaction. And if SwapTokenHash is specified, the transferable amount will be returned.

Parameter

/* @SrcChainId:    source chain id
 * @SwapTokenHash: the hash of the cross-chain token on the source chain
 * @Hash: The token hash used to charge fees
 * @DstChainId: target chain id
*/
