Message Module

Messages specified by BandChain. All messages presented in this module are extended from Protobuf's messages, which are generated from these proto files. For specification can be found here.

Here are methods that are extended from original protobuf classes.

---

toAny

Returns an Google Protobuf's Any instance that are used to construct transactions.

Return

• Any - a Google Protobuf's Any instance containing serialized messaged and type URL

Example

import { Message, Coin } from '@bandprotocol/bandchain.js'
const { MsgRequestData } = Message

const sender = 'band17n5rmujk78nkgss7tjecg4nfzn6geg4cvaqt5h'
const oracleScriptId = 37
const calldata = Buffer.from('0000000200000003425443000000034554480000000000000064', 'hex')
const askCount = 4
const minCount = 3
const clientId = 'from_bandchain.js'
const msg = new MsgRequestData(oracleScriptId, calldata, askCount, minCount, clientId, sender)

const any = msg.toAny()
console.log(any.getTypeUrl())
console.log(any.getValue_asB64())

Result

/oracle.v1.MsgRequestData

validate

Validates the message in a basic manner to ensure that there are no invarient values stored in the message instance. If message's validation fails, it will throw the exception.

Example

import { Message, Coin } from '@bandprotocol/bandchain.js'
const { MsgSend } = Message

const sender = 'band17n5rmujk78nkgss7tjecg4nfzn6geg4cvaqt5h'
const receiver = 'band1p46uhvdk8vr829v747v85hst3mur2dzlmlac7f'
const sendAmount = new Coin()
sendAmount.setDenom('uband')
sendAmount.setAmount('10')
const msg = new MsgSend(sender, receiver, [sendAmount])

msg.validate()
