Lock user's assets into cBridge contract, mint corresponding tokens to receiver which address can be any length
TransferAgent transfer is not recommended if receiver's wallet address is no more than 20 bytes
Implementation
Through TransferAgent's transfer function, user can specify token to be locked on source chain and receiver's address on destination chain. According to pegged_pair_config.vault_version, you should set different parameters communicating with TransferAgent contract.
Communicate with OriginalTokenVault through TransferAgent contract
transferAgent!.transfer( receiverAddress /// Destination chain receiver address, could be any length.pegConfig.config.org_token.token.address /// Source chain token address value,/// Transfer amount destinationChainId,/// Destination Chain Id nonce,/// Current timestamp0,/// Canonical token transfer doesn't require max slippage2,/// BridgeSendType.PegDeposit/// https://github.com/celer-network/sgn-v2-contracts/blob//// c66326d458b9d34058ed960f610af69d8514716c/contracts//// libraries/BridgeTransferLib.sol#L27 [] /// Extensions are not required )

Request Parameters
TransferId Generation
When you submit on-chain mint transaction through TransferAgentContract, you can also generate a transfer id for future reference. For example, it is used for getTransferStatus. It should be the same as transferId inside on-chain transaction log.
Transfer Id Generation with OriginalTokenVault

Transfer Id Generation with OriginalTokenVaultV2
constmint_id=ethers.utils.solidityKeccak256( ["address","address","uint256","uint64","address","uint64","uint64","address", ], ["...",/// TransferAgent contract address"...",/// Token address on source chain,"...",/// Mint amount in String "12360001",/// Destination Chain Id"0x0000000000000000000000000000000000000000",/// Hardcoded address zero"...",/// Nonce"...",/// Source chain id"...",/// Original Token Vault V2 contract address on source chain ],)
Response
Since this function is an on-chain transaction, the response is the corresponding transaction response.
