Methods

DeriveContract(string, NextContractPurpose, ArkContract[], ContractActivityState, Dictionary<string, string>?, CancellationToken)

Derives a new contract for the specified purpose, with optional input contracts for descriptor recycling. When inputContracts are provided and purpose is SendToSelf, HD wallets may reuse a descriptor from the inputs to avoid index bloat and reduce contract data accumulation. Inputs the wallet is still advertising as an inbound destination are skipped, since recycling deactivates the reused script — see GetNextContract(NextContractPurpose, ContractActivityState, ArkContract[]?, CancellationToken).

public Task<ArkContract> DeriveContract(string walletId, NextContractPurpose purpose, ArkContract[] inputContracts, ContractActivityState activityState = ContractActivityState.Active, Dictionary<string, string>? metadata = null, CancellationToken cancellationToken = default)

Parameters

walletId string

purpose NextContractPurpose

inputContracts ArkContract[]

activityState ContractActivityState

metadata Dictionary<string, string>

cancellationToken CancellationToken

Returns

Task<ArkContract>

DeriveContract(string, NextContractPurpose, ContractActivityState, Dictionary<string, string>?, CancellationToken)

public Task<ArkContract> DeriveContract(string walletId, NextContractPurpose purpose, ContractActivityState activityState = ContractActivityState.Active, Dictionary<string, string>? metadata = null, CancellationToken cancellationToken = default)

Parameters

walletId string

purpose NextContractPurpose

activityState ContractActivityState

metadata Dictionary<string, string>

cancellationToken CancellationToken

Returns

Task<ArkContract>

ImportContract(string, ArkContract, ContractActivityState, Dictionary<string, string>?, CancellationToken)
