Since 2012, Trail of Bits has helped secure some of the world’s most targeted organizations and products. We combine high-end security research with a real-world attacker mentality to reduce risk and fortify code.

Building and using cryptographic libraries is notoriously difficult. Even when each component of the system has been implemented correctly (quite difficult to do), improperly combining these pieces can lead to disastrous results.

Cryptography, when rolled right, forms the bedrock of any secure application. By combining cutting-edge mathematics and disciplined software engineering, modern crypto-systems guarantee data and communication privacy. Navigating these subtleties requires experts in both cryptography software engineering and the underlying mathematics. That’s where we can help.

Simple Secure Storage Service (S4) is Least Authority's verifiably secure off-site backup system for individuals and businesses. We never see your data, you can always see our code.

Least Authority was formed in 2011 to create freedom-compatible technologies and moved to Berlin in 2016. We are a small team who believe that freedom matters in Internet technology. You can take advantage of online services while retaining control over your own data. We're here to make it easy.

Our mission is to build an affordable, ethical, usable, and lasting data storage solution. We believe this requires Free and Open Source software, end-to-end cryptography, user-friendly interfaces, and a sustainable economic model.

We run a verifiably-secure cloud backup system, S4 - Simple Secure Storage Service.

We also perform security audits and have done it for a variety of open-source projects, including CryptoCat, GlobalLeaks, SpiderOak, & Ooni. We were hired by Ethereum to perform an incentive analysis on the proof-of-work puzzle, Ethash, and the gas mechanism.

Zapper.fi, manage, monitor and deploy your DeFi assets and liabilities in one simple interface.

DeFiSnap + DeFiZap are merging to create Zapper.fi - the ultimate hub for DeFi.

DeFiZap was a system of smart contracts - Zaps - that deploys your Ether (and soon DAI) across multiple DeFi protocols in one transaction, saving your time.

DeFiZap doesn’t spread your Ether into 'top 10 on coinmarketcap' - Zaps infuse Ether into DeFi protocols built on top of Ethereum, furthering user adoption.

When you use DeFiZap, you mint & receive the same liquidity/position tracking tokens as when separately using Uniswap, Compound, bZx, Synthetix, etc. on your own.
