Meet Spot, a beautifully designed mobile app to control your cryptocurrencies. Spot looks like a portfolio-tracking app. But the company has built a strong foundation to add more features in the coming months. Spot wants to be your unique gateway to the world of cryptocurrencies.

“Spot’s vision isn’t to build a portfolio tracker — we went a bit overboard with this feature,” co-founder and CEO Edouard Steegmann told me. “Eventually, we want to become the app to manage all your cryptos, a sort of Revolut but with a crypto DNA.”

When you first install the app, you can connect it to your existing wallets by adding public addresses. Even if you store your tokens on a hardware wallet, Spot can read the public details of your wallet to show them in the app.

“We have our own nodes on Ethereum, Bitcoin, Litecoin, Stellar and others to recover the amount on your wallet,” Steegmann said. Data is also cross-checked with third-party services to make sure that everything is fine.

Spot also lets you connect to an exchange account using API keys. Right now, the app supports Binance, Kraken, Bitfinex and Poloniex, but the company already plans to add more exchanges.

The app then gives you a detailed overview of your holdings across all services and wallets. You can see detailed charts, and discover which token is performing better than the rest. It’s also one of the most well-designed mobile apps I’ve seen this year — the animations and interactions are gorgeous.

But Spot doesn’t rely on an API to get pricing information for each token. “We’ve rebuilt CoinMarketCap from the ground up, and we’re one of the few companies that have done it,” Steegmann said. The company stores pricing information for dozens of tokens across 150 exchanges. That’s a lot of pairings.

If you tap on the Spot logo at the top of the app, you can see the maximum value of your portfolio if you cash out on exchanges with the highest prices for your tokens. The company makes sure that there’s enough volume to show you coherent prices.

Spot thinks that controlling your own data is too important to rely on API calls. When you have your own data, you don’t have any API rate limits, you don’t have a major dependency and you can scale more calmly.

Up next, you’ll be able to trade directly in the app. The company isn’t going to build its own exchange, but you can expect to buy and sell tokens on a third-party exchange without having to visit the website.

“We think that many things will be tokenized and that there’s no user-friendly interface to transfer, receive, buy and sell,” Steegmann said.

The company raised a $1.2 million round (€1.056 million to be exact) from Kima Ventures and business angels, including Eric Larchevêque and Thomas France from Ledger, Jean-Daniel Guyot, Thibaud Elzière, Eduardo Ronzano, Nicolas Steegmann, Sébastien Lucas and Nicolas Debock.
