Functions

func AssetsFromOutput added in v0.3.0 

func AssetsFromOutput(o iotago.Output) *isc.FungibleTokens

func BasicOutputFromPostData added in v0.3.0 

func BasicOutputFromPostData(
	senderAddress iotago.Address,
	senderContract isc.Hname,
	par isc.RequestParameters,
) *iotago.BasicOutput

BasicOutputFromPostData creates extended output object from parameters. It automatically adjusts amount of base tokens required for the storage deposit

func CreateAndSignTx added in v0.3.0 

func CreateAndSignTx(inputs iotago.OutputIDs, inputsCommitment []byte, outputs iotago.Outputs, wallet *cryptolib.KeyPair, networkID uint64) (*iotago.Transaction, error)

func FilterOutputIndices added in v0.3.0 

func FilterOutputIndices(outputs []iotago.Output, ids []*iotago.UTXOInput, filters ...OutputFilter) ([]iotago.Output, []*iotago.UTXOInput)

FilterOutputIndices returns a slice of indices of those outputs which satisfy all predicates Uses same underlying arrays slices

func GetAliasOutput 

func GetAliasOutput(tx *iotago.Transaction, aliasAddr iotago.Address) (*isc.AliasOutputWithID, error)

func GetAnchorFromTransaction added in v0.3.0 

func GetAnchorFromTransaction(tx *iotago.Transaction) (*isc.StateAnchor, *iotago.AliasOutput, error)

GetAnchorFromTransaction analyzes the output at index 0 and extracts anchor information. Otherwise error

func MakeAnchorTransaction added in v0.3.0 

func MakeAnchorTransaction(essence *iotago.TransactionEssence, sig iotago.Signature) *iotago.Transaction

func MakeBasicOutput added in v0.3.0 

func MakeBasicOutput(
	targetAddress iotago.Address,
	senderAddress iotago.Address,
	assets *isc.FungibleTokens,
	metadata *isc.RequestMetadata,
	options isc.SendOptions,
	disableAutoAdjustStorageDeposit ...bool,
) *iotago.BasicOutput

MakeBasicOutput creates new output from input parameters. Auto adjusts minimal storage deposit if the notAutoAdjust flag is absent or false If auto adjustment to storage deposit is disabled and not enough base tokens, returns an error

func MakeSignatureAndAliasUnlockFeatures added in v0.3.0 

func MakeSignatureAndAliasUnlockFeatures(totalInputs int, sig iotago.Signature) iotago.Unlocks

func MakeSignatureAndReferenceUnlocks added in v0.3.0 

func MakeSignatureAndReferenceUnlocks(totalInputs int, sig iotago.Signature) iotago.Unlocks

func NFTOutputFromPostData added in v0.3.0 

func NFTOutputFromPostData(
	senderAddress iotago.Address,
	senderContract isc.Hname,
	par isc.RequestParameters,
	nft *isc.NFT,
) *iotago.NFTOutput

func NewChainOriginTransaction 

func NewChainOriginTransaction(
	keyPair *cryptolib.KeyPair,
	stateControllerAddress iotago.Address,
	governanceControllerAddress iotago.Address,
	deposit uint64,
	unspentOutputs iotago.OutputSet,
	unspentOutputIDs iotago.OutputIDs,
) (*iotago.Transaction, *isc.ChainID, error)

NewChainOriginTransaction creates new origin transaction for the self-governed chain returns the transaction and newly minted chain ID

func NewMintNFTTransaction added in v0.3.0 

func NewMintNFTTransaction(par MintNFTTransactionParams) (*iotago.Transaction, error)

func NewRequestTransaction 

func NewRequestTransaction(par NewRequestTransactionParams) (*iotago.Transaction, error)

NewRequestTransaction creates a transaction including one or more requests to a chain. Empty assets in the request data defaults to 1 base token, which later is adjusted to the minimum storage deposit Assumes all UnspentOutputs and corresponding UnspentOutputIDs can be used as inputs, i.e. are unlockable for the sender address

func NewRootInitRequestTransaction 

func NewRootInitRequestTransaction(
	keyPair *cryptolib.KeyPair,
	chainID *isc.ChainID,
	description string,
	unspentOutputs iotago.OutputSet,
	unspentOutputIDs iotago.OutputIDs,
	initParams ...dict.Dict,
) (*iotago.Transaction, error)

NewRootInitRequestTransaction is a transaction with one request output. It is the first request to be sent to the uninitialized chain. At this moment it is only able to process this specific request. The request contains the minimum data needed to bootstrap the chain. The signer must be the same that created the origin transaction.

func NewRotateChainStateControllerTx added in v0.3.0 

func NewRotateChainStateControllerTx(
	chainID iotago.AliasID,
	newStateController iotago.Address,
	chainOutputID iotago.OutputID,
	chainOutput iotago.Output,
	kp *cryptolib.KeyPair,
) (*iotago.Transaction, error)

func NewTransferTransaction added in v0.3.0 

func NewTransferTransaction(params NewTransferTransactionParams) (*iotago.Transaction, error)

NewTransferTransaction creates a basic output transaction that sends L1 Token to another L1 address

func NftOutputFromBasicOutput added in v0.3.0 

func NftOutputFromBasicOutput(o *iotago.BasicOutput, nft *isc.NFT) *iotago.NFTOutput
