A library for secure smart contract development. Build on a solid foundation of community-vetted code. OpenZeppelin Contracts uses semantic versioning to communicate backward compatibility of its API and storage layout. To keep your system secure, you should always use the installed code as-is, and neither copy-paste it from online sources nor modify it yourself.

...Commercial licenses are available from Paragon Initiative Enterprises if you wish to extend Halite without making your derivative works available under the terms of the MPL. If you are satisfied with the terms of MPL software for backend web applications but would like to purchase a support contract for your application that uses Halite, those are also offered by Paragon Initiative Enterprises.

...LiquidHaskell (LH) refines Haskell's types with logical predicates that let you enforce important properties at compile time. LH warns you that head is not total as it is missing the case for [] and checks that it is total on NonEmpty lists. The input contract propagates to uses of head which are verified by ensuring the arguments are NonEmpty. LH lets you avoid off-by-one errors that can lead to crashes or buffer overflows. Dependent contracts let you specify, e.g. that dotProduct requires equal-sized vectors. LH checks that functions terminate and so warns about the infinite recursion due to the missing case in fib.

...If you are testing the network or developing unstable software on Qtum, we highly recommend using either testnet or regtest mode. A Proof of Stake consensus system which is optimized for Qtum's contract model. Any user can stake and help to secure the network. There is no voting, master nodes, or minimum amount required. There have been transactions as small as 2 Qtum that have created blocks in the past. Staking from smart contracts is under development.

This project is intended to demonstrate that current popular approaches to software security (e.g. DAC, VMA randomization, etc) are not sufficient and that other approaches should be considered more seriously (e.g. MAC, design by contract).
