Slice Wallet is a safe SPV Wallet to send and receive Sumcoin. Slice Wallet is not an exchange service.

Sumcoin is a cryptographic blockchain and the worlds first cryptographic Index which uses a proof-of-work algorithm to unlock coins. Its maximum targeted processing time is only 3 mins with a maximum supply of only 100 M coins. Sumcoin is Segwit enabled and open source.

• The Index
• Sumcoin, or the "SUM" of coins means that it tracks all coins in near real time from over 600 different data points. Sumcoin is continuously aggregating and finds what the current top 100 coins are by global market cap. The "SUM" price is using algorithms.

• Given the speed, security and simplicity being able to hold the "SUM" of the market in only one coin, Sumcoin is for those who want to gain maximum exposure to the crypto space but may only want to hold one coin for simplicity, which can have an effect of reduced risk factors. As the value is spread across 100 coins, there is a great reduction of volatility to Sumcoin vs any other coin.

• Sumcoin Mining works with Slice Wallet.


* Your purchase of Slice Wallet does not include any Sumcoins. Slice Wallet is like it sounds, a Wallet. It allows you to store and use your Sumcoins in a safe and easy way.

• Slice Wallet is the first standalone Sumcoin Wallet built for iOS with a focus on accessibility, security and simplicity. Developed by Sumcoinlabs, Slice Wallet makes getting started with Sumcoin easier than ever!

• There aren't any hidden servers to backup or store your coins, you're in control 100%.

• Backup and recover your wallet on any device with the 'recovery phrase' generated by the app. Even if you lose your phone you will not lose your Sumcoin.

• As long as you store the (12) generated words in order #1-#12, keep in a vault and NEVER share, you can have complete confidence in being your own bank.

• NEVER backup your recovery words using a camera/photo

• Send and receive Sumcoin at the touch of a button, anytime, anywhere and to anyone else using Slice Wallet.

How many good things can I say?

Love the speed, the ease, and the technology provided with this app.
Trading Bitcoin with people is so slow but Sumcoin allows me to trade with someone and not lose hours of the day wondering when the TX will finish.
Sumcoin being an Index coin makes it more stable and simplistic to use crypto.
Impressive to say the least!

Sum coin must be a scam... why can’t I convert it back to cash or at least Bitcoin?

I’ve looked all over the internet and have not found a way to cash out my coins... however you can very easily buy sum coins or convert from any other crypto into it, but once they have your money or value.... there is no way to get a return on your investment nor a way to use the currency outside of their marketing merchandise... it’s foul. Also they have zero ways to contact them to even inquire... complete TAKERS and classic Ponzi scheme.... please prove me wrong with facts and receipts or bear witness to my claim.

Fast and easy to use

This wallet is easy to use especially for transfers between other Sumcoin users. Not sure how long transactions will take between other currencies or at atms. Excited be able to buy and sell with other crypto.
