Enigma has published a complete “table of contents” for developers looking to get started building their own secret contracts. Now you can find links to several sample contracts, and Enigma’s team recommendation for when to use these as starting points. A lot of efforts were put forth by the developers on Gitcoin and some applications were built.
Secret Access Control enables access-control (similar to proxy re-encryption) with Enigma, so that users can encrypt messages or data for specific recipients.
Secret Data Validation enables users to encrypt data and check their encrypted data set against another user’s encrypted data set.
Non-Fungible Token Lottery makes use of Enigma’s native random-number-generator to award a secret lottery prize (a non-fungible token) to a winner.
Secret Benchmarking enables users to submit a “baseline” data set, and then check to see whether data points submitted fall within certain percentiles of the existing dataset.

Development
Secret Contracts
Enigma’s Secret Contracts are written in Rust. See here for links to several sample contracts, and Enigma’s recommendation for when to use these as starting points.
Millionaire’s Problem
Compare two numbers without revealing the underlying data.
- This is a good starting point for: blind auctions or as an alternative to range proofs.
- Github
Using Encryption Libraries
Use an encryption library within a secret contract.
- Good starting point for: applications which require the use of a relayer (i.e., coin-mixing), where a task is sent to an intermediary before being passed to the network.
- Github
Ethereum Calls
Calling a function of an Ethereum Contract from within a Secret Contract
- Useful reference for any application where the outcome of a secret contract should result in some action being taken within an Ethereum Smart Contract.
- Github
Enigma Randomness Service
Using the Enigma Randomness Service to generate randomness within Secret Contracts.
- This is a useful reference for any application incorporating shuffling, lotteries, or other randomness.
- Github
Secret Voting
Tally encrypted votes.
- This helps prevent vote bribery and is an alternative to commit-reveal patterns, which have poor UX.
- Github
All sample contracts:

Sample Applications
These sample applications demonstrate different use-cases for Enigma. All come with front-end UIs and demonstrate the integration of Enigma JS with secret contracts.
Secret Access Control
This application enables access-control (similar to proxy re-encryption) with Enigma, so that users can encrypt messages or data for specific recipients. In the sample application (described more in-depth in the github repo), the owner of the secret contract is able to encrypt messages specifically for other users from a list of possible recipients.
This is a good starting point for applications that:
- Send messages to users based on their membership in a whitelist (i.e., subscriptions)
- Send messages on certain conditions (i.e., a dead-mans switch)
- Hide messages until users fulfill a task (scavenger hunt)
Secret Data Validation
This sample application enables users to encrypt data and check their encrypted data set against another user’s encrypted data set.
This is a good starting point for applications such as:
- Secret auctions
- Checking that a verifiable claim lies within a certain range (i.e., user is over 21)
- Enabling whistleblowers to ensure that their data matches without revealing it publicly
- Games that check one player’s move against another (i.e., rock-paper-scissors)

Non-Fungible Token Lottery
This application makes use of Enigma’s native random-number-generator to award a secret lottery prize (a non-fungible token) to a winner.
This is a good starting point for applications that:
- Require the use of a random number for any reason
- Dice games
- Use NFTs
- Select a single person from a pool of applicants for some reason
- See also: Simple example of Enigma Randomness Service
Secret Benchmarking
This application enables users to submit a “baseline” data set, and then check to see whether data points submitted fall within certain percentiles of the existing dataset.
This is a good starting point for applications that:
- Check to see if a smaller data subset falls acceptably within the norm of a larger set
- Perform secret data analysis of any kind
- Use any type of common benchmarking: salary, price quotes from contractors
Coin Join
This application is a coin-mixer, based on the coin join protocol, that uses Enigma to give users transactional privacy. It showcases Ethereum callbacks as well as the enigma randomness service.
Social encounters
The thirty-first episode of Decentralize This!, Enigma’s podcast hosted by Tor Bair, featured Andreas M. Antonopoulos.
Andreas is a best-selling author, speaker, educator, and one of the world’s foremost bitcoin and open blockchain experts. In 2014, he wrote one of the foundational books of the blockchain space, Mastering Bitcoin. He is also the author of The Internet of Money as well as his most recent book, Mastering Ethereum. He is widely respected in the blockchain space for not only his knowledge and ceaseless curiosity about decentralized technologies, but also for his extreme generosity in teaching others.
Past events:
Finance
For the past months, Enigma has been working with developers on @gitcoin to complete its first wave of bounty projects. See all the applications on Enigma’s blog.
Roadmap
