Getting Started
You will need authentication to Paras if you want to:
- 1.Create a publication
- 2.Edit collection
- 3.Create collections
- 4.Edit collections
- 5.Upload files
All direct function call to the smart contract would authentication with the near blockchain. To generate auth token please look at the following script,
const nearAPI = require('near-api-js')
const { Base64 } = require('js-base64')
const authToken = async (accountId, signer, networkId) => {
try {
const arr = new Array(accountId)
for (var i = 0; i < accountId.length; i++) {
arr[i] = accountId.charCodeAt(i)
}
const msgBuf = new Uint8Array(arr)
const signedMsg = await signer.signMessage(
msgBuf,
accountId,
networkId
)
const pubKey = Buffer.from(signedMsg.publicKey.data).toString('hex')
const signature = Buffer.from(signedMsg.signature).toString('hex')
const payload = [accountId, pubKey, signature]
return Base64.encode(payload.join('&'))
} catch (err) {
console.log(err)
return null
}
}
const main = async () => {
const config = {
networkId: 'testnet',
nodeUrl: 'https://rpc.testnet.near.org',
walletUrl: 'https://wallet.testnet.near.org',
appName: 'Paras Testnet',
contractName: `paras-token-v2.testnet`
}
try {
// Initializing nearAPI
// Login and init contract
const keyStore = new nearAPI.keyStores.UnencryptedFileSystemKeyStore(
`${process.env.HOME}/.near-credentials/`
)
const signer = new nearAPI.InMemorySigner(keyStore)
const connection = await nearAPI.connect({
deps: {
keyStore: keyStore,
},
...config,
})
const account_id = 'orang.testnet'
const account = await connection.account(account_id)
const authorizationHeader = await authToken(account_id, signer, config.networkId)
console.log(`Authorization Header : ${authorizationHeader}`)
} catch (err) {
throw err
}
}
main()
We have two main smart contracts,
- 1.NFT contract (x.paras.near) -- serves all the NFT created on Paras. this is where NFT will be minted from the creator
- 2.Marketplace (marketplace.paras.near) -- secondary market, this is where buy and sale single NFT happens
