Taidl
We present Taidl, an app that makes payment with cryptocurrency easy. You don't have to be an expert in blockchain. You don't need to worry about high transaction fee or fluctuation in the conversion rate. Taidl is powered with xDai, a stablecoin that lives on a sidechain of Ethereum. The transaction fee is as low as $0.01 for 500 transactions, making it the perfect solution to peer-to-peer payments, local business payments, online payments and international transfers.
Taidl app has even more exciting features that assists you in your daily spending. There is a address book for storing your contacts, so you don't need to search and type the receipient account every time you pay. You can scan a QR code to make a payment. You can check your transaction history to keep track of your finance.
The registration process is especially easy. Just sign up with your favorite user name, which does not have to be your real name. Type in your password, just like you are using any traditional finance app without the burden to understand how cryptocurrency works. For experts and nerds who want full control of the crypto wallet, we can handle over the custody of private keys to you. Otherwise your private keys will be securely stored in our encrypted server as safe as a bank.
Inspirations
🙊 Traditional crypto wallet apps are designed for expert users, traders and geeks. Unfriendly UI and complex technical functions can easily intimidate normal users. We keep the usability in mind when designing the interaction. We greatly reduce the complexity of using a mobile crypto wallet without sacrificing core functions or safety.
🎰 The price of crypto assets like BTC, ETH fluctuate heavily so they are not suitable for everyday uses. We adopts a stablecoin solution - xDai, an asset that is pegged to US Dollar. 1 xDai = 1 USD in almost every time. You don't need to worry about the conversion rate when paying and receiving money with xDai
⚡️ Transactions on xDai chain happen incredibly fast - 10~15 seconds to everywhere in the world! The transaction fee does not depend on the amount that you transfer. It's one same price for $1 and $10,000. Fee is as low as $0.0002 for each transaction.
🍩 In the near future cryptocurrency will become more mainstream with a larger user base. Small businesses who do not want to pay for credit card channels will benefit the most. Just print a QR code sticker at the checkout. Let customers scan the code and payment is done!
🌞 For international students and international travellers, you will not need to worry about expensive fiat conversions. With blockchain, you can go anywhere in the world and use the same currency, or you can exchange xDai for local currency with small fees.
