Functions

func AdjustToMinimumStorageDeposit added in v1.0.3 

func AdjustToMinimumStorageDeposit[T iotago.Output](out T) T

func AssetsFromOutput added in v0.3.0 

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

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 ComputeInputsAndRemainder added in v1.0.3 

func ComputeInputsAndRemainder(
	senderAddress iotago.Address,
	baseTokenOut uint64,
	tokensOut map[iotago.NativeTokenID]*big.Int,
	nftsOut map[iotago.NFTID]bool,
	unspentOutputs iotago.OutputSet,
	unspentOutputIDs iotago.OutputIDs,
) (
	iotago.OutputIDs,
	*iotago.BasicOutput,
	error,
)

computeInputsAndRemainder computes inputs and remainder for given outputs balances. Takes into account minimum storage deposit requirements The inputs are consumed one by one in the order provided in the parameters. Consumes only what is needed to cover output balances Returned reminder is nil if not needed

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 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 L1CommitmentFromAliasOutput added in v1.0.3 

func L1CommitmentFromAliasOutput(ao *iotago.AliasOutput) (*state.L1Commitment, 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.Assets,
	metadata *isc.RequestMetadata,
	options isc.SendOptions,
) *iotago.BasicOutput

MakeBasicOutput creates new output from input parameters (ignoring storage deposit).

func MakeRequestTransactionOutput added in v1.0.3 

func MakeRequestTransactionOutput(par NewRequestTransactionParams) iotago.Output

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 NewMintNFTsTransaction added in v1.0.3 

func NewMintNFTsTransaction(par MintNFTsTransactionParams) (*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

	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
