We have integrated Binance Smart Chain to @CryptoBot for sending/receiving BNB and USDT. BSC provides lower transaction fees and 3-second block time – as a result, saving both time and money.

Financial Revolution. Quickly send crypto using virtual checks right in Telegram. Forget about long addresses and transaction confirmations.

Simply type @send to create a check in any chat from the message input field. After tapping the ‘Receive…’ button, coins will be instantly deposited to the recipient’s wallet.

If you want your check to be activated by a specific member of a group chat or to add some comment, enter a message in the format “@send $100 @durov Thank you.”

We added new BUSD and USDC (BEP20) stablecoins to @CryptoBot. Withdrawals and deposits for them can be made only via Binance Smart Chain for the moment.

💎 Considering the recent news about the transfer of the ton.org domain to the TON Foundation community, we have increased the exchange rate for TON coin by x1.5. The new purchase price is ~$0.12.

Go to @CryptoBot and open ‘Exchange’ to sell TON coins and get BTC.

💎 TON payments update for @CryptoBot

We have upgraded, tested and released a new version of the TON payment provider that handles sending and receiving transactions for @CryptoBot more accurately now.

Many thanks to the TON devs community for consultations and advices.

Invoices done right. Request and accept payments in crypto using invoices from @CryptoBot.

Simply type @CryptoBot to create an invoice in any chat from the message input field. The recipient will be able to pay your invoice with any cryptocurrency – BTC, TON, USDT, BUSD, USDC or BNB. If the recipient doesn’t have any crypto yet, they can buy it using our Market.

You can also raise funds by creating a multi-use invoice. Anyone will be able to send you a donation and post a comment to your channel. Try this in @CryptoBotDonates – raised funds will be used to build a better future and buy fancy clothes for our dogs. 🐕

To create a multi-use invoice, go to @CryptoBot and choose Invoices.

💸 Please note that @CryptoBot has no option to add a comment when sending TON as required to deposit coins on exchanges such as EXMO, FTX, Okex and use blockchain bridges.

To send transactions with a comment, use wallet apps from ton.org/wallets.

If you have already sent your coins with no comment added, contact the support of the exchange for further details. In the meantime, you can still deposit TON to @CryptoBot with no extra steps. 🦋

🏝 We start testing Crypto Pay at @CryptoTestnetBot.

If you find any issue, report it to our chat or support bot.

We are glad to see that our Checks Platform is actively used throughout Telegram. Today, the minimum limit for one check was increased to $0.01 to improve user experience.

We have added BNB coin to our P2P Market. Now you can create your offer to sell or buy BNB and start trading.

We have added a new feature to Invoice Platform. Now you can add a hidden message that will be shown to the recepient after an invoice is paid.

You can use this feature to build a paywall and monetize a content of your Telegram channel or chat. For this, create an invite link for join requests and add a hidden message to your invoice.

To try this feature, go to Invoices, create a new invoice and choose 'Hidden Message...'

🎁 The perfect gift for any person is...

Cryptocurrency. It's obvious that cryptocurrency is already an important part of our life and will not leave it in the near future.

3. New world. Cryptocurrency gift will open up a new world for a person, new opportunities and freedom of decentralization that can fundamentally change their worldview.

Use @CryptoBot to buy cryptocurrency via Market with 0% fees and then instantly gift it by check to your friends right in Telegram.
