Rupiah Token Issued IDRTB Stablecoin on Binance Chain

By Anthony Thio & Rupiah Token Team

Jakarta, 17 August 2019 — On this 74th Indonesian Independence Day, Rupiah Token team proudly announces that we issued IDRTB, the first Indonesian Rupiah-collateralized Stablecoin on Binance Chain!

Background

We, PT Rupiah Token Indonesia, are the creator and issuer of IDRT, an ERC-20 token that is the first stablecoin backed by Indonesian Rupiah. After the launch of IDRT in early 2019 on the Ethereum mainnet, we have been hard at work adding accessibility for both domestic and international users.

Now, on this 74th Indonesian Independence Day, we proudly announce that we have added a new blockchain protocol for Rupiah Token: Binance Chain! Our Binance Chain token, IDRTB, is built on the BEP-2 token standard, and we are very excited to introduce the first Rupiah stablecoin to the ecosystem.

The birth of IDRTB: https://explorer.binance.org/tx/17827319CBA3F4C6FDA4487B258B2B44BE70402D62621B04253F5F8C9CFD72B7

Multiple Firsts for Rupiah Token and Binance Chain

The issuance of IDRTB on Binance Chain is a significant milestone for both Rupiah Token and the Binance community as it will be the first Southeast Asian Fiat-backed Stablecoin on Binance DEX. In addition, we plan to propose listing of IDRTB as a cross-currency listing pair on Binance DEX with other stablecoins in Binance Chain.

Frequently Asked Questions

Why Binance Chain?

We are a blockchain-agnostic company and believe that each blockchain has its own edge. With the Binance Chain, we believe that there is an incredible use case for building a decentralized exchange (DEX) with one-second block confirmation times and ability to process thousands of transactions a second. Furthermore, we believe that Binance DEX, the decentralized exchange feature developed on top of the Binance Chain blockchain, provides a safer mechanism for end-users to trade as they maintain control over their private keys and trade directly wallet-to-wallet.

What is IDRTB?

IDRTB is basically the Binance Chain version of IDRT. One IDRTB is a 1:1 representation of an Indonesian Rupiah on the Binance Chain. Each IDRTB is 100% collateralized by a corresponding IDR held in accounts subject to regular public reporting of reserves and is kept in an Indonesian Bank account. PT Rupiah Token also serves as an on/off ramp for customers to purchase/redeem their fiat for IDRT and IDRTB.

Why IDRTB?

If IDRTB listing proposal to the DEX is approved by validators, IDRTB will be the first non-USD stablecoin to launch on Binance DEX. We believe that this listing will open a world of new opportunities for the economy:

  1. The addition of IDRTB on the Binance Chain will offer Indonesian traders a better experience when accessing the Binance DEX, as all trades can be done and settled in Rupiah.
  2. There is already at least one USD-based stablecoin, USDSB, listed on Binance Chain. If IDRTB received enough votes to get traded against USDSB, the Binance DEX ecosystem will be one step further in creating multi-currency stablecoin pairs that opens the door for 24/7 forex trading, import/export settlement, and real-time international remittance.

When will IDRTB be listed / tradable in Binance DEX?

We will submit proposals for listing IDRTB against other Binance Chain assets on the DEX over the coming weeks.

Where can I purchase or redeem IDRTB?

Just like IDRT, you will be able to Purchase or Redeem IDRTB directly at https://rupiahtoken.com. 1 IDRTB can always be purchased for 1 Rupiah, or redeemed back into 1 Rupiah (minus 0.5% fee + bank transfer fee if any). This will be available by end of August 2019, stay tuned!

Can I swap IDRT with IDRTB and vice-versa?

We will allow swapping of IDRT with IDRTB in our website. The feature is still under development, and we expect to enable this in September 2019.

In the long run, we are exploring opportunities to list IDRTB / IDRT trading pair on Binance.com for more options and user convenience. Stay tuned!

Detailed Implementation Explanation

IDRTB Set-up

Due to the way the Binance Chain is structured, we cannot frequently mint and burn IDRTB. Instead, we used the following approach:

  • We minted max supply (90 billion) of IDRTB, which we transferred into a secure Treasury Wallet. Then, we froze all 90 billion IDRTB tokens.
  • Whenever we need to introduce IDRTB into circulating supply, we will unfreeze the IDRTB from Treasury Wallet and send it to recipient address.
  • Frozen IDRTB on the Treasury Wallet are not collateralized by Fiat Rupiah. Unfrozen IDRTB (in circulation) will be backed 1-to-1 by Fiat Rupiah (just like our ERC-20 stablecoin, IDRT).

Introducing IDRTB into circulation

When we need to introduce more IDRTB into circulation, the following steps will be taken:

  • IDR fiat currency will be added to Rupiah Token reserve
  • An equivalent amount of IDRTB will be unfrozen from Treasury Wallet

Removing IDRTB from circulation

When we need to reduce IDRTB from circulation, the following steps will be taken:

  • IDRTB will be sent to Treasury Wallet and frozen
  • An equivalent amount of IDR fiat currency will be removed from Rupiah Token reserve.

Transparency

Both IDRT and IDRTB (unfrozen) are fully backed 1:1 by Rupiah in our reserves, as follows:

  • Total IDR fiat in reserve bank = Total IDRT in circulation + Total IDRTB in circulation
  • Total IDRTB in circulation = 90 billion (max supply) — frozen IDRTB in Treasury Wallet.

Frozen IDRTB are not in circulation and not backed by IDR.

To ensure transparency, the public can audit us as follows:

Trade IDRT with 600+ other tokens on Uniswap!

Trade 600+ tokens with IDRT on Uniswap!

Rupiah Token team is glad to announce that IDRT is now tradable on Uniswap! You can now swap IDRT with ETH or 600+ ERC20 tokens such as USDC, TUSD, BAT, ZRX, DAI, and many others 🙂

What is Uniswap?

Uniswap is a unique type of DEX (decentralized exchange) built on top of Ethereum blockchain. A recipient of Ethereum Foundation grant, Uniswap is entirely run by smart contracts on Ethereum blockchain. It has no order book and no bid & ask prices. Instead, prices of token swaps are determined purely by mathematical formula based on relative amount of tokens available in the Uniswap smart contract ecosystem.

What are the key benefits of using Uniswap?

  • Trade IDRT against ETH or 600+tokens!
  • No registration / KYC needed — you just need a Metamask or Web3-compatible wallet (such as Trust Wallet’s dapp browser).
  • 100% uptime and instant liquidity — all swaps are done by smart contracts.
  • Open source project & platform — all smart contract functions are public on GitHub.
  • Lowest gas cost compared to most decentralized exchanges.

How can I trade IDRT using Uniswap?

Requirements:

  • Make sure you are using a Metamask or Web3-compatible wallet such as Trust Wallet’s dapp browser. For help setting up IDRT, click here.
  • Make sure you have a small amount of ETH for transaction gas fee (about ~0.0005 ETH per transaction).

Step-by-step example for token swap:

We will show example to swap IDRT to other ERC-20 token below:

  • Open Uniswap interface at https://uniswap.exchange/.
  • Click ‘Connect’ button on top right section of the page to connect Uniswap to your Web3-compatible wallet.

Click the ‘Connect’ button to connect the interface with Ethereum wallet.
  • Click token selection button on the Input field.

Choose the token to sell.
  • Input the amount of IDRT you want to trade. If this is your first time, Uniswap smart contract will need to ask your approval to spend your token. Click ‘Unlock’ to continue.

Click the “Unlock” button if this is your first time using Uniswap
  • Clicking “Unlock” will create a “transaction” request that will give permission to Uniswap smart contract to move your IDRT for future swap transactions. Click approve/confirm.
    (Note: if you are using Metamask, you can ignore the weird number appearing on “Total” column — no IDRT tokens are going to be moved on this transaction).
After approval is done, we are ready to swap! In the example below, we want to swap 14376 IDRT to DAI. Simply put in the desired token pairs and amount — the exchange rate will be calculated immediately.

Put an amount of IDRT to swap it with other token
  • Click ‘Swap’ button. There will be a confirmation for transaction from your wallet application, simply confirm or approve the transaction to continue.
  • Wait for the smart contract to work its magic. After several block confirmations (typically 1–3 minute), check your wallet and see that your transaction is done!

This is cool! How does Uniswap really work?

Multiple exchange contracts facilitate token conversion

Quoting from the official documentation:

  • Uniswap is made up of a series of ETH-ERC20 exchange contracts.
  • There is exactly one exchange contract per ERC20 token
  • Exchange contracts are automated market makers between an ETH-ERC20 pair
  • Since ETH is a common pair for all ERC20 exchanges, it can be used as an intermediary allowing direct ERC20-ERC20 trades in a single transaction

Basically, every ERC20 in Uniswap is paired to ETH using a specific exchange contract. The contract stores both the ERC20 token and a corresponding amount of ETH in the smart contract (along with other information for token exchange).

The exchange price between a specific ERC-20 token and ETH is determined by using the model x*y = k, where x and y are the supplies of ERC20 token and ETH in that contract, while k is a constant. These supplies set the exchange rate between ERC-20 and ETH. Now, because all ERC-20 tokens can be swapped to ETH, the ETH can be used as intermediary to directly swap any ERC-20 token pairs (such as IDRT and USDC).

Traders and liquidity providers

In Uniswap, there are two main parties at play: traders and liquidity providers. Traders can freely trade tokens or ETH on Uniswap, while liquidity providers provide ERC-20 tokens and ETH (liquidity) for traders to trade with. The Uniswap contract automatically takes 0.3% fee for each trade, and this fee is proportionally distributed to all liquidity providers.

What’s more unique is that anyone can fill these roles, you can be a trader and gain profit by price difference or arbitraging. Or you can be a liquidity provider and get incentivized for providing liquidity.

Rupiah Token Launches IDRT, the First Rupiah Stablecoin

By Anthony Thio & Rupiah Token Team

Rupiah Token team is excited to announce that we have officially launched IDRT, the first Stablecoin that is backed 1:1 with Indonesian Rupiah (IDR).

Through our website, you can always convert 1 IDR into 1 IDRT. You can also convert IDRT back to IDR, making it simple for you to move between fiat and crypto.

Visit us at (https://rupiahtoken.com)to learn more and get started!

What is IDRT ?

  • IDRT is a price-stable crypto asset (commonly called stablecoin) on the Ethereum blockchain that is backed 1-to-1 by IDR fiat deposits.
  • The price of 1 IDRT is pegged at 1 Rupiah, because we guarantee that on our website, you can always convert 1 IDR into 1 IDRT and vice-versa.
  • For each IDRT minted, we store 1 IDR fiat currency in a designated bank account. If IDRT is redeemed back to fiat IDR, we will “burn” or destroy the redeemed IDRT, removing those from the supply. This way, each IDRT in circulation is fully backed by IDR Rupiah.

What can I use IDRT for?

Blockchain-based digital assets (such as Bitcoin or Ethereum) are not suitable as a unit of account due to their inherent price volatility. IDRT eliminates that volatility while keeping the desired characteristics of Ethereum blockchain transaction — fast processing speed, immutable, and global.

In the short run, the most ready use case for IDRT is for Indonesian crypto traders who want to trade out of cryptocurrencies into Rupiah. In the long run, having Rupiah in the blockchain will enable more interesting use cases such as trusted borderless payments, remittances, and potentially new form of e-commerce. We will post updates on this blog, stay tuned!

How Can I Purchase / Redeem IDRT?

IDRT can be purchased/redeemed directly at https://rupiahtoken.com.
