Transaction Builder

begin_builder_transaction

Create a new transaction builder.

Handle of the new transaction builder.

add_operation_to_builder_transaction

Append a new operation to a transaction builder.

transaction_handle: handle of the transaction builder
op: the operation in JSON format

replace_operation_in_builder_transaction

Replace an operation in a transaction builder with a new operation.

handle: handle of the transaction builder
operation_index: the index of the old operation in the builder to be replaced
new_op: the new operation in JSON format

set_fees_on_builder_transaction

Calculate and update fees for the operations in a transaction builder.

asset graphene::wallet::wallet_api::set_fees_on_builder_transaction(
    transaction_handle_typehandle, 
    string fee_asset = GRAPHENE_SYMBOL)

handle: handle of the transaction builder
fee_asset: name or ID of an asset that to be used to pay fees

Total fees.

preview_builder_transaction

Show content of a transaction builder.

transaction graphene::wallet::wallet_api::preview_builder_transaction(
    transaction_handle_typehandle)

handle: handle of the transaction builder

A transaction.

sign_builder_transaction

Sign the transaction in a transaction builder and optionally broadcast to the network.

signed_transaction graphene::wallet::wallet_api::sign_builder_transaction(
    transaction_handle_typetransaction_handle, 
    bool broadcast = true)

transaction_handle: handle of the transaction builder
broadcast: whether to broadcast the signed transaction to the network

A signed transaction.

propose_builder_transaction

Create a proposal containing the operations in a transaction builder (create a new proposal_create operation, then replace the transaction builder with the new operation), then sign the transaction and optionally broadcast to the network.

signed_transaction graphene::wallet::wallet_api::propose_builder_transaction(
    transaction_handle_typehandle, 
    time_point_sec expiration = time_point::now() + fc::minutes(1), 
    uint32_t review_period_seconds = 0, 
    bool broadcast = true)

handle: handle of the transaction builder
expiration: when the proposal will expire
review_period_seconds: review period of the proposal in seconds
broadcast: whether to broadcast the signed transaction to the network

A signed transaction.

propose_builder_transaction2

signed_transaction graphene::wallet::wallet_api::propose_builder_transaction2(
    transaction_handle_typehandle, 
    string account_name_or_id, 
    time_point_sec expiration = time_point::now() + fc::minutes(1), 
    uint32_t review_period_seconds = 0, 
    bool broadcast = true)

handle: handle of the transaction builder
account_name_or_id: name or ID of the account who would pay fees for creating the proposal
expiration: when the proposal will expire
review_period_seconds: review period of the proposal in seconds
broadcast: whether to broadcast the signed transaction to the network

A signed transaction.

remove_builder_transaction

Destroy a transaction builder.

void graphene::wallet::wallet_api::remove_builder_transaction(
    transaction_handle_typehandle)

handle: handle of the transaction builder

serialize_transaction

Converts a signed_transaction in JSON form to its binary representation.

string graphene::wallet::wallet_api::serialize_transaction(
    signed_transaction tx)const

tx: the transaction to serialize

The binary form of the transaction. It will not be hex encoded, this returns a raw string that may have null characters embedded in it

sign_transaction

Signs a transaction.

Given a fully-formed transaction that is only lacking signatures, this signs the transaction with the necessary keys and optionally broadcasts the transaction.

signed_transaction graphene::wallet::wallet_api::sign_transaction(
    signed_transaction tx, 
    bool broadcast = false)

tx: the unsigned transaction
broadcast: true if you wish to broadcast the transaction

The signed version of the transaction

get_prototype_operation

Returns an uninitialized object representing a given blockchain operation.

This returns a default-initialized object of the given type; it can be used during early development of the wallet when we don’t yet have custom commands for creating all of the operations the blockchain supports.

operation graphene::wallet::wallet_api::get_prototype_operation(
    string operation_type)

operation_type: the type of operation to return, must be one of the operations defined in graphene/protocol/operations.hpp (e.g., “global_parameters_update_operation”)

A default-constructed operation of the given type.
