Faced with challenges to proper storage of funds, the blockchain-cryptocurrency community is witnessing the rise of some of the best crypto custody providers. Often, hardware wallets holding cryptocurrencies have been lost or corrupted, resulting in the irretrievable loss of funds. Similarly, exchange platforms have been hacked, and their funds stolen.

Ever since Bitcoin’s release in 2008, blockchain and cryptocurrency has emerged as one of the fastest proliferating industries of our times. Every day, several projects with immense potential are being launched around the world. In turn, there’s an exponential rise in the value generated and locked in the sector. Understandably, such immense value needs to be secured, and in this regard, blockchain’s inherent security features might not be enough. Against this backdrop, we discuss top cryptocurrency custody solutions for 2021.

What is a cryptocurrency custody service?

For proper understanding, let’s begin with a definition of custodian services:

In simple terms, a cryptocurrency custody service is a secure, off-chain storage solution for cryptocurrencies. Although accessible to individual users, these services are usually designed for institutional investors who store large amounts of funds.

To ensure optimal security, the best crypto custodians often leverage a combination of hot and cold wallets. By definition, hot wallets are online wallets and are thus prone to hacks (hot storage). Yet, they are also more seamless. Cold wallets, on the other hand, store funds offline, which enhances the security but hampers accessibility to some extent (cold storage).

Why is crypto custody important?

Businesses transact and hold cryptocurrencies worth millions of dollars, which demand professional and specialized storage solutions. Furthermore, in the United States, investments over 150K USD are legally bound to employ certified cryptocurrency custody providers. Therefore, alongside the growth in the value invested in the blockchain-cryptocurrency sector, the demand and need for reliable custody service providers is on the rise.

Having understood the definition and significance of custody services, let us now discuss some of the best in class crypto custodian projects.
