Terra’s bank module inherits from the Cosmos SDK’s bank module. This document is a stub and covers mainly important Terra-specific notes about how it is used.
The bank module is the base transactional layer of the Terra blockchain. This module allows assets to be sent from one Account to another. The bank module defines the following types of send transactions: MsgSend and MsgMultiSend.
Message types#
MsgSend#
// MsgSend - high level transaction of the coin module
type MsgSend struct {
FromAddress sdk.AccAddress `json:"from_address"`
ToAddress sdk.AccAddress `json:"to_address"`
Amount sdk.Coins `json:"amount"`
}
The Bank module is used to send coins from one Terra account to another. MsgSend is constructed to facilitate the transfer. If the balance of coins in the sender Account is insufficient or the recipient Account is unable to receive the funds via the bank module, the transaction fails. Fees already paid through failed transactions are not refunded.
MsgMultiSend#
// MsgMultiSend - high level transaction of the coin module
type MsgMultiSend struct {
Inputs []Input `json:"inputs"`
Outputs []Output `json:"outputs"`
}
To send multiple transactions at once, use MsgMultiSend. For each transaction, Inputs contains the incoming transactions, and Outputs contains the outgoing transactions. The Inputs coin balance must exactly match the Outputs coin balance. Batching transactions via MsgMultiSend conserves network bandwidth and gas fees. Taxes and fees already paid through failed transactions are not refunded.
