Use Cases Overview

Simplicity can be used for a wide range of financial applications.

Our reference implementations

Examples we've developed ourselves include

• Simplicity DEX for financial options
• Simplicity Lending Protocol for collateralized lending (implementation)
• SHRINCS Simplicity verifier, our project for Simplicity-based postquantum signature verification on Liquid

Simplicity projects built by others

• Resolvr has created Astrolabe, a Simplicity-based reinsurance investment platform, and Deadcat, a Simplicity-based prediction market.
• SideSwap has launched Swaption, a Simplicity-based noncustodial binary options marketplace.
• StarkWare has used Simplicity to implement a STARK verifier.
• OceanSlim has created anchor, a constant-product automated-market maker (AMM).

Other examples and ideas

Check out the SimplicityHL examples for other introductory smart contract examples, including vault and covenant mechanisms.

In addition to options, lending, insurance, and prediction markets, we've envisioned that Simplicity will be used for

• Cross-chain atomic swaps
• Crowdfunding contracts

• Bitcoin native smart contracts via Simplicity Unchained
• Vaults (multi-stage withdrawals)
