Security is a primary concern for Helio. We set the highest possible standard for security in our protocol
When you participate in Web3 activities such as buying NFTs, investing in DeFi or using payment solutions such as Helio, you are exposed to certain risks similarly. As a Web3 user you can mitigate these risks with best practices (and we write about these frequently on our blog) and stay informed. In addition to your personal security, it's our job to help you understand the technical risks of using Helio and how we mitigate them.

Blockchain risks

When you use Helio for payments, you use our protocol that's built on the Solana blockchain. If the Solana blockchain were to be attacked successfully, the funds on Helio could be at risk.
We've chosen Solana because it's the cheapest, fastest and greenest Blockchain around, AND most importantly because it has one of the highest security practices in the industry. Solana has been audited by Kudelski Security and is a blockchain that operates with a hybrid consensus mechanism (integrating Tower BFT and Proof-of-History).

Contract risks

In Web3, any protocol can potentially be attacked by hackers. They look for loopholes and bugs that allow them to abuse the protocol for their gain. We focus heavily on security and regularly conduct formal audits. The smartcontract framework that powers the Helio protocol is Audited by:
Ackee Blockchain
Ackee Blockchain specializes in audits and security assessments and has worked on the security of major blockchains such as Ethereum, Solana and Celo. Their audit has allowed us to further improve the security standard of our protocol and please find a copy here:
