tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.

Readme
Anchor.js is a client SDK for building applications that can interact with Anchor Protocol from within JavaScript runtimes, such as web browsers, server backends, and on mobile through React Native.
You can find a reference of the Anchor.js API here.
Anchor.js is available as a package on NPM and is intended to be used alongside Terra.js.
Add both:
@terra-money/terra.js
@anchor-protocol/anchor.js
To your JavaScript project's package.json
as dependencies using your preferred package manager:
$ npm install -S @terra-money/terra.js @anchor-protocol/anchor.js
Anchor.js provides class wrapper facade for the usual operations available on webapp.
import { LCDClient, MnemonicKey, Fee, Wallet } from '@terra-money/terra.js'
import { Anchor, columbus5, AddressProviderFromJson, MARKET_DENOMS, OperationGasParameters } from '@anchor-protocol/anchor.js'
const addressProvider = new AddressProviderFromJson(columbus5)
const lcd = new LCDClient({ URL: 'https://lcd.terra.dev', chainID: 'columbus-5' })
const key = new MnemonicKey({
mnemonic: 'your key'
})
const wallet = new Wallet(lcd, key)
const anchor = new Anchor(lcd, addressProvider)
// you can generate message only, using your wallet
const msgs = anchor.earn.depositStable(MARKET_DENOMS.UUSD, "100.5000").generateWithWallet(wallet)
// you can ALSO generate message only, using your address in string
const msgs = anchor.earn.depositStable(MARKET_DENOMS.UUSD, "100.5000").generateWithAddress("terra1...")
// or, you can broadcast the tx using your wallet
// below is the recommended default setting for gas parameters.
// of course you can tailor it to your needs
const gasParameters: OperationGasParameters = {
gasAdjustment: 1.4,
gasPrices: "0.15uusd",
// or if you want to fixate gas, you can use `fee`
fee: new Fee(gasToSpend, "100000uusd")
}
const txResult = await anchor.earn.depositStable(MARKET_DENOMS.UUSD, "100.5000").execute(wallet, gasParameters)
When working with bAsset's, they can be loaded in one of two ways.
import { LCDClient, MnemonicKey, Fee, Wallet } from '@terra-money/terra.js'
import { Anchor, columbus5, bAssetColumbus5, AddressProviderFromJson, MARKET_DENOMS } from '@anchor-protocol/anchor.js'
const addressProvider = new AddressProviderFromJson(columbus5)
const lcd = new LCDClient({ URL: 'https://lcd.terra.dev', chainID: 'columbus-5' })
const key = new MnemonicKey({
mnemonic: 'your key'
})
const wallet = new Wallet(lcd, key)
const anchor = new Anchor(lcd, addressProvider)
// load the bAsset from the available whitelisted collateral
const collaterals = await anchor.moneyMarket.getCollateralWhitelist({
market: MARKET_DENOMS.UUSD,
});
const [collateral] = collaterals.filter(
(collateral) => collateral.symbol === 'BETH',
);
const bAsset = await anchor.bAsset(collateral);
// alternatively, the bAsset can be loaded with the symbol and market demons
const bAsset = await anchor.bAsset({ symbol: 'BETH', market: MARKET_DENOMS.UUSD });
// once you have the bAsset, you can then perform operations
const operation = bAsset.claim({ recipient: 'terra1...' });
Anchor.js provides facilities for 2 main use cases:
MsgExecuteContract
objects to be used in transactionsBoth of these functions are accessible through the Message Fabricators
.
To Use the message fabricators:
Note: Please note that market
is a different variable from the coin denom. The denomination for the coins in the example is set to be uusd
.
import {fabricateRedeemStable, fabricateDepositStableCoin} from '@anchor-protocol/anchor.js';
import {AddressProviderFromJson} from "@anchor-protocol/anchor.js";
// default -- uses bombay core contract addresses
const addressMap = somehowGetAddresses();
const addressProvider = new AddressProviderFromJson(addressMap);
const redeemMsg = fabricateRedeemStable({
address: 'terra123...',
market: 'usd',
amount: '10000',
})(addressProvider);
const depositMsg = fabricateDepositStableCoin({
address: 'terra123...',
market: 'usd',
amount: '10',
})(addressProvider);
A message fabricator contains functions for generating proper MsgExecuteContract
messages to be included in a transaction and broadcasted.
import { LCDClient, Wallet, MnemonicKey, Fee} from '@terra-money/terra.js';
const anchor = new LCDClient({ URL: 'https://bombay-lcd.terra.dev', chainID:'bombay-12' });
const owner = new MnemonicKey({ mnemonic: "...."});
const wallet = new Wallet(anchor, owner);
async function depositStable() {
const tx = await wallet.createAndSignTx({
msgs: depositMsg,
fee: new Fee(2_000_000, { uluna: 2_000_000 })
});
return await anchor.tx.broadcast(tx);
}
async function main() {
await depositStable()
.then((result) => {
console.log(result);
})
.catch(console.error);
}
main();
