/ Pre-image hash to be used for signing

Used in: PreSigningOutput

• bytes data_hash = 1

  / Pre-image data hash that will be used for signing

• bytes public_key_hash = 2

  / public key hash used for signing

Bitcoin transaction out-point reference.

Used in: TransactionInput, UnspentTransaction, Decred.Proto.TransactionInput

• bytes hash = 1

  The hash of the referenced transaction (network byte order, usually needs to be reversed).

• uint32 index = 2

  The index of the specific output in the transaction.

• uint32 sequence = 3

  Transaction version as defined by the sender.

/ Transaction pre-signing output

• repeated HashPublicKey hash_public_keys = 1

  / hash, public key list

• Common.Proto.SigningError error = 2

  / error code, 0 is ok, other codes will be treated as errors

• string error_message = 3

  / error description

Input data necessary to create a signed transaction.

Used in: THORChainSwap.Proto.SwapOutput

• uint32 hash_type = 1

  Hash type to use when signing.

• int64 amount = 2

  Amount to send. Transaction created will have this amount in its output, except when use_max_amount is set, in that case this amount is not relevant, maximum possible amount will be used (max avail less fee). If amount is equal or more than the available amount, also max amount will be used.

• int64 byte_fee = 3

  Transaction fee rate, satoshis per byte, used to compute required fee (when planning)

• string to_address = 4

  Recipient's address, as string.

• string change_address = 5

  Change address, as string.

• repeated bytes private_key = 6

  The available secret private key or keys required for signing (32 bytes each).

• map<string, bytes> scripts = 7

  Available redeem scripts indexed by script hash.

• repeated UnspentTransaction utxo = 8

  Available input unspent transaction outputs.

• bool use_max_amount = 9

  Set if sending max amount is requested.

• uint32 coin_type = 10

  Coin type (used by forks).

• optional TransactionPlan plan = 11

  Optional transaction plan. If missing, plan will be computed.

• uint32 lock_time = 12

  Optional lockTime, default value 0 means no time locking. If all inputs have final (`0xffffffff`) sequence numbers then `lockTime` is irrelevant. Otherwise, the transaction may not be added to a block until after `lockTime`. value < 500000000 : Block number at which this transaction is unlocked value >= 500000000 : UNIX timestamp at which this transaction is unlocked

• bytes output_op_return = 13

  Optional zero-amount, OP_RETURN output

Result containing the signed and encoded transaction. Note that the amount may be different than the requested amount to account for fees and available funds.

• optional Transaction transaction = 1

  Resulting transaction.

• bytes encoded = 2

  Signed and encoded transaction bytes.

• string transaction_id = 3

  Transaction ID (hash)

• Common.Proto.SigningError error = 4

  Optional error

• string error_message = 5

  error description

A transaction, with its inputs and outputs

Used in: SigningOutput

• sint32 version = 1

  Transaction data format version.

• uint32 lockTime = 2

  The block number or timestamp at which this transaction is unlocked.

• repeated TransactionInput inputs = 3

  A list of 1 or more transaction inputs or sources for coins.

• repeated TransactionOutput outputs = 4

  A list of 1 or more transaction outputs or destinations for coins.

Bitcoin transaction input.

Used in: Transaction

• optional OutPoint previousOutput = 1

  Reference to the previous transaction's output.

• uint32 sequence = 2

  Transaction version as defined by the sender.

• bytes script = 3

  Computational script for confirming transaction authorization.

Bitcoin transaction output.

Used in: Transaction

• int64 value = 1

  Transaction amount.

• bytes script = 2

  Usually contains the public key as a Bitcoin script setting up conditions to claim this output.

Describes a preliminary transaction plan.

Used in: SigningInput

• int64 amount = 1

  Amount to be received at the other end.

• int64 available_amount = 2

  Maximum available amount in all the input UTXOs.

• int64 fee = 3

  Estimated transaction fee.

• int64 change = 4

  Remaining change

• repeated UnspentTransaction utxos = 5

  Selected unspent transaction outputs (subset of all input UTXOs)

• bytes branch_id = 6

  Zcash branch id

• Common.Proto.SigningError error = 7

  Optional error

• bytes output_op_return = 8

  Optional zero-amount, OP_RETURN output

An unspent transaction output, that can serve as input to a transaction

Used in: SigningInput, TransactionPlan

• optional OutPoint out_point = 1

  The unspent output

• bytes script = 2

  Script for claiming this UTXO

• int64 amount = 3

  Amount of the UTXO
