Straightforward and uncomplicated process Overview is a grizzled veteran in terms of crypto services. It was founded in 2011 by Ben Reeves under the name and was initially designed for bitcoin analysis.

In 2012 Reeves collaborated with Coinbase founder Brian Armstrong in famed tech startup Y Combinator. Both were working on a payment platform for bitcoin where users could make payments in bitcoin and exchange bitcoin for other currencies.

Reeves and Armstrong parted ways over differing opinions on custodial wallets. Armstrong believed that exchanges should control users’ cryptocurrency, while Reeves believed that users should retain their private keys.

Armstrong went on to co-found Coinbase, which is one of the most successful custodial wallets on the market. Reeves had his own success; by 2014, was the most popular bitcoin wallet. As of 2021, there are 65 million wallets, and 28% of bitcoin transactions since 2012 were initiated or received by a wallet.

It’s not a surprise that the wallet is such a success. It’s open-source and non-custodial. In terms of wallets for popular exchanges, it’s a unicorn. offers access to sophisticated APIs that come with a community of 25,000+ developers.

Security is one of the select few crypto exchanges that has yet to be hacked.

Users are strongly encouraged to use two-factor authentication, which can be set up with SMS, Yubikey, or Google Authenticator. There is a comprehensive security overview page on the support section which goes over best practices for different tokens.

There are also other user-side security measures offered under the Advanced Security Settings in the wallet. Users can set up an IP whitelist, block wallet access via anonymous browser Tor, and use PBKDF2 password stretching.

While their security overview is a little vague, appears to conform to industry standard security practice. They use standardized cryptography to encrypt user information. Funds are mostly held in cold storage, unconnected to the Internet and protected from potential theft. The exchange offers an ongoing bug bounty on HackerOne that encourages security researchers to alert the team to potential exploits, and uses internal monitoring.
