Cross Chain Service

Chainge cross chain service is powered by Chainge's cutting edge cross-chain technology powered by Fusion DCRM.

Chainge cross chain SDK could support 28 chains including most popular EVM chains such as Ethereum and non-EVM chains such as Solana.

In version 1.0, Chainge is going to provide all supported EVM chains in our cross-chain infrastructure to public. However, we are busy working on including our supported non-EVM chains now.

To be noticed, we do not have a testnet environment. All the transactions should be on mainnet. To test a transaction, one could send a small amount like $1 on a low gas network such as fusion.

There are four steps for a cross-chain transaction.

1. get a cross chain quote

Get a quote for a cross chain transaction

POST /open/v1/order/getCrossChainQuote

Headers

Name	Type	Description
appKey*	String	developer account appKey
expireTime*	Int	timeout time in ms for a request
signature*	String	signature generated to verify developer account. Please refer to Signature verification to generate a signature
timestamp*	Int	current timestamp used in signature verification

Request Body

Name	Type	Description
amount*	float	token amount to be crossed without token decimal
fromChain*	String	from chain name from supported Chains API request result
toChain*	String	to chain name from supported Chains API request result
token*	String	token to be crossed from supported tokens API request result
feeLevel*	Int	Please refer to fee structureFee Structure

200: OK

{
  "code": 0,
  "data": {},
  "msg": "string",
  "status": 0
}

2. get a transaction raw

Get a raw for users to sign and then broadcast

POST /open/v1/order/getTransferToMinterRaw

Headers

timestamp*	Int	current timestamp used in signature verification

Request Body

Name	Type	Description
amount*	float	token amount to be crossed without token decimal
chain*	String	original chain name from supported Chains API request result
evmAddress*	String	user evm Address
token*	String	token symbol to be crossed from supported tokens API request result
fromAddress*	String	user from address (If it is from a EVM chain, the address is same as evmAddress)

200: OK

{
  "code": 0,
  "data": {},
  "msg": "string",
  "status": 0
}

3. Submit transaction to hash
