io-creata-js v1.0.1

This library provides supports for creata transaction signing and broadcasting.

Installation

In order to fully use this library, you need to run a local or remote full node and set up its rest server.

NPM

npm install io-creata-js

Yarn

yarn add io-creata-js

Browser Support

This version does not support browsers

Import

NodeJS

const ioCreata = require("io-creata-js");

Usage

• Generate address from mnemonic

const ioCreata = require("io-creata-js");

const chainId = "testnet";
const creata = ioCreata.network("YOUR_NODE_URL", chainId);

const mnemonic = "YOUR_SEED_PHRASE"
creata.setPath("m/44'/118'/0'/0/0"); //hd path for creata
const address = creata.getAddress(mnemonic);
const ecpairPriv = creata.getECPairPriv(mnemonic);

Generate ECPairPriv value that is needed for signing signatures

const ecpairPriv = creata.getECPairPriv(mnemonic);

Transfer cta to designated address.

• Make sure to input proper type, account number, and sequence of the creata account to generate StdSignMsg. You can get those account information on blockchain

creata.getAccounts(address).then(data => {
	let stdSignMsg = creata.newStdMsg({
		msgs: [
			{
				type: "creata-sdk/MsgSend",
				value: {
					amount: [
						{
							amount: String(100), 	// 6 decimal places ( 1 cta = 1000000fcta)
							denom: "fcta"           // coin denomination is fcta
						}
					],
					from_address: address,
					to_address: "creata1da4v3fxy3xkkgqr5g60cjmcpvjcjdd5e4m0qwa"
				}
			}
		],
		chain_id: chainId,
		fee: { amount: [ { amount: String(20000), denom: "fcta" } ], gas: String(200000) },
		memo: "creata_test_memo",
		account_number: String(data.result.value.account_number),
		sequence: String(data.result.value.sequence)
	});

	const signedTx = creata.sign(stdSignMsg, ecpairPriv);
	creata.broadcast(signedTx).then(response => console.log(response));
})	...
})

Sign transaction by using stdSignMsg and broadcast by using /txs REST API

const signedTx = creata.sign(stdSignMsg, ecpairPriv);
creata.broadcast(signedTx).then(response => console.log(response));

Validate Wallet Address

creata.validateAddress("creata1da4v3fxy3xkkgqr5g60cjmcpvjcjdd5e4m0qwa")

Wallet Address Balance

creata.getAddressBalance("creata1da4v3fxy3xkkgqr5g60cjmcpvjcjdd5e4m0qwa")
