Quickstart
An API instance must be initialize using the initializeApi function in ternoa-js/blockchain before calling some SDK functions. The default chain endpoint is:
DEFAULT_CHAIN_ENDPOINT = "wss://alphanet.ternoa.com".
It can be modified by passing a new endpoint as a parameter to the initializeApi function.
Functions are organized by theme. In the example below, the import of generateSeed and getKeyringFromSeed from the subpath ternoa-js/account allows us to generate a new account and display its address.
import { generateSeed, getKeyringFromSeed } from "ternoa-js/account";
(async () => {
const account = await generateSeed()
const keyring = await getKeyringFromSeed(account.seed)
const address = keyring.address
console.log("Your fresh public address is: ", address)
})().catch((e) => {
console.log(e)
})
Among all the features provided by the Ternoa SDK, this short snippet of code allows you to create an NFT, submit and sign it at a glance.
This single line createNft function, require a few parameters :
  • some offchainData metadatas,
  • a royalty,
  • a collectionId
if you want this NFT to belong to a collection, a boolean to define its isSoulbound status, the keyring to sign and submit the transaction, and a waitUntil callback parameter, to define at which point we want to get the results of the transaction execution.
import { createNft } from "ternoa-js/nft"
import { generateSeed, getKeyringFromSeed } from "ternoa-js/account"
const createMyFirstNFT = async () => {
try {
// We initialize an API instance connected to the Alphanet chain
await initializeApi()
// Here we create, sign and submit the NFT transaction with your keyring
await createNft("My first NFT", 10, undefined, false, keyring, WaitUntil.BlockInclusion)
} catch (e) {
console.log(e)
}
}
