Functions

func BuildRLPInput

func BuildRLPInput(address, currency string, value uint64) []byte

Build the RLP encoded input to the smart contract that deposit() will accept. The format of the UTXO inputs, outputs, and ownership data is critical. If any value is incorrect the deposit will be rejected by the smart contract and transaction reversed. The correct format is: [[[0,0,0],[0,0,0],[0,0,0],[0,0,0]],[[owner_public, eth_raw, 10], [eth_raw, eth_raw, 0], [eth_raw, eth_raw, 0], [eth_raw, eth_raw, 0]]] where eth_raw is 20 bytes of 0.
