High-Assurance
Financial Programming

Automate financial workflows with confidence. Deploy on the Bitcoin stack.

Better Contracts, Fewer Risks.

Simplicity provides the security assurances that high-value financial applications need.

Unlock Deep Liquidity

Simplicity isn't just powerful—it's fun! If you know Rust, you already know Simplicity. It's straightforward, no steep learning curves.

Trust the Math, Not the Middlemen

Every Simplicity contract offers cryptographic assurance instead of counterparty risk. You don't need to hope it works—you can prove it will.

Less Risk, Greater Rewards

Trade and settle assets on Bitcoin's most secure sidechain, Liquid, with instant finality, no capital lockups, and no reliance on custodians.

Built-In Compliance

Transparent, auditable, self-enforcing contracts that leave no room for ambiguity.

Are you building a speculative consumer application, or are you engineering a piece of critical financial infrastructure?

Simplicity enables a brand new way to innovate with digital assets without the technical and financial risk of the current ecosystem.

Create auditable digital instruments whose behavior can be proven to regulators and stakeholders.

Build novel, revenue-generating financial products on a platform that’s anchored to Bitcoin’s security model.

WithoutSimplicity

Shaky Execution

The Ethereum's DAO Hack lost $60M+ because of external calls placed before state updates allowed attackers to recursively drain funds.

Costly Escrow & Intermediaries

Complex multi-party agreements rely on expensive lawyers and escrow agents to ensure obligations are met, adding time and cost.

Illiquid, Siloed Assets

Trillions of dollars in assets like real estate and private equity are locked in illiquid forms, with high barriers to entry and inefficient price discovery.

WithSimplicity

Provable Execution Path

Have complete understanding of a program's behavior prior to execution. Re-entrancy is a non-existent class of bug.

Self-Enforcing Programmable Agreements

Encode complex, multi-stage contracts where funds are released automatically based on verifiable on-chain events, removing the need for trusted third parties.

Programmable Tokenization for 24/7 Liquidity

Simplicity enables the creation of “smart securities” with embedded logic. These can be traded in automated, on-chain liquidity pools, creating deep, continuous liquidity for traditionally illiquid assets.

Simplicity in the Real World

Here’s what verifiable contracts on Bitcoin enable:

Instant Contract Settlement Without Capital Lockup

Execute agreements in seconds, not days. Free up liquidity and eliminate capital lockups while maintaining Bitcoin-grade security.

Programmable, Flexible Custody & Security

Build custody solutions that adapt to your governance model that enables secure, flexible, and policy asset management.

Payment Escrows for Staged Settlement

Automate staged payouts and conditional transfers that reduce counterparty risk and manual oversight.

Simplicity’s strength comes from deep, foundational principles in type theory. SimplicityHL, as a frontend, abstracts away much of the complexity, allowing users to write smart contracts, with minimal code and high reliability. SimplicityHL keeps the computer science fundamentals close enough that you can reason about it formally when needed.
