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")
