Mapping

  1. TRC20 mapping
// Called by the deployer of the TRC20 contract on the main-chain to complete the mapping of the TRC20 contract from the main-chain to the side-chain, the standard 20 contract deployed in the side-chain corresponds to the main-chain TRC20 contract.
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().mappingTrc20(trxHash, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this mapping operation.

2. TRC721 mapping

// Called by the deployer of the TRC721 contract on the main-chain to complete the mapping of the TRC721 contract from the main-chain to the side-chain, the standard TRC721 contract will be deployed in the side-chain corresponding to the main-chain TRC721 contract.
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().mappingTrc721(trxHash, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this mapping operation.

Deposit

  1. TRX deposit
//Pledge a certain number of TRX from the main-chain to the side-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().depositTrx(num, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this deposit operation.

2. TRC10 token deposit

//Pledge a certain number of designated TRC10 from the main-chain to the side-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().depositTrc10(tokenId, tokenValue, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this deposit operation.

3. TRC20 token deposit

//Pledge a certain number of designated TRC20 from the main-chain to the side-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().depositTrc20(contractAddrStr, num, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this deposit operation.

4. TRC721 token deposit

//Pledge a certain number of designated TRC721 from the main-chain to the side-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().depositTrc721(contractAddrStr, num, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this deposit operation.

Withdraw

  1. TRX withdraw
//Exit a certain number of TRX from the side-chain to the main-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().withdrawTrx(num, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this withdraw operation.

2. TRC10 token withdraw

//Pledge a certain number of designated TRC10 from the side-chain to the main-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().withdrawTrc10(tokenId, tokenValue, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this withdraw operation.

3. TRC20 token withdraw

//Pledge a certain number of designated TRC20 from the side-chain to the main-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().withdrawTrc20(contractAddrStr, num, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this withdraw operation.

4. TRC721 token withdraw

//Pledge a certain number of designated TRC721 from the side-chain to the main-chain
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().withdrawTrc721(contractAddrStr, num, feeLimit);
//Return value: Use sdk.getSideChainService().getTransactionInfoById(txid) to query resp.getData().getTrxId() to get the nonce value of this withdraw operation.

Retry

  1. Retry deposit
//Retry the unsuccessful main-chain deposit operation
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().retryDeposit(nonce, feeLimit);

2. Retry withdraw

//Retry the unsuccessful side-chain withdraw operation
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().retryWithdraw(nonce, feeLimit);

3. Retry mapping

//Retry the unsuccessful main-chain mapping operation
SunNetworkResponse<TransactionResponse> resp = sdk.getCrossChainService().retryMapping(nonce, feeLimit);
