Functions

func AmountToFloat40 added in v0.1.5 

func AmountToFloat40(amount *big.Int) (*big.Int, error)

func AtomicTransfer added in v0.1.3 

func AtomicTransfer(hezClient client.HermezClient, txs []AtomicTxItem) (serverResponse string, atomicGroupID hezCommon.AtomicGroupID, err error)

AtomicTransfer creates PoolL2Txs using basic information provided in the AtomicTxItems, set metadata and fields based on the current state. Also links the txs setting the Rq* fields and sign txs. After performs token or ETH transfers in a pool of transactions.

func AtomicTransferJSON added in v0.1.4 

func AtomicTransferJSON(hezClient client.HermezClient, txsJSON []string) (serverResponse string, atomicGroupID hezCommon.AtomicGroupID, err error)

AtomicTransferJSON receives an array of AtomicTxItems in JSON format, create PoolL2Txs, atomic group, sign and post

func BjjToString 

func BjjToString(bjj babyjub.PublicKeyComp) string

BjjToString convert the BJJ public key to string

func CreateFullTxs added in v0.1.4 

func CreateFullTxs(hezClient client.HermezClient, txs []AtomicTxItem) (fullTxs []hezCommon.PoolL2Tx, err error)

CreateFullTxs turn the basic information in a PoolL2Tx, set metadata and fields based on the current state. Also links the txs setting the Rq* fields.

func IdxToHez 

func IdxToHez(idx hezCommon.Idx, tokenSymbol string) string

IdxToHez convert idx to hez idx

func SendAtomicTxsGroup added in v0.1.4

Types

type APITx 

type APITx struct {
	TxID      hezcommon.TxID `json:"id" binding:"required"`
	Type      string         `json:"type"`
	TokenID   uint32         `json:"tokenId"`
	FromIdx   string         `json:"fromAccountIndex" binding:"required"`
