The future of verifiable apps will be written in open code.

After months of battle-testing, three major refactors, and relentless dogfooding, WAVS (Web Assembly Verifiable Services) is now open source. For those unfamiliar, think of WAVS as the Vercel for Verifiable Services. Deploy complex, multichain applications as easily as deploying a web app.

WAVS is built on the shoulders of open source projects like Foundry from Paradigm, CosmWasm, and Wasmtime from the Bytecode Alliance. We're proud to have WAVS join this ecosystem as a public good, and through our GPLv3 license, ensure that all future WAVS-based applications preserve the open source ethos.

Open source isn't just how we planned to build WAVS, it's how we guarantee that the infrastructure powering the next generation of verifiable applications remains transparent, permissionless, and community-driven.

WAVS Gone OSS

The Layer development team will continue supporting WAVS with the same commitment as before. What changes now is that we're no longer building in isolation.

Community-driven evolution: Since launching WAVS, we've received countless requests from builders to view the codebase, understand the architecture, and implement features like custom API support. Open source transforms these requests into contributions that benefit the entire ecosystem.

Verifiable infrastructure demands transparency: Every component must be auditable when applications handle real value and critical decisions. Open source removes trust assumptions, enabling security researchers to verify cryptographic implementations and consensus mechanisms.

Eliminating vendor lock-in: Truly decentralized applications need infrastructure that can't disappear. Open source ensures WAVS evolves as a public good, maintained by and for the community that depends on it.

Breaking Smart Contract Limits

Smart contracts have a fundamental problem: they're not smart enough. They have limited compute, no async operations, scaling bottlenecks, and restricted storage. These constraints have kept the most ambitious blockchain applications trapped in theoretical whitepapers rather than production systems.

WAVS shatters these limitations. Unlike traditional smart contracts, WAVS can read from any blockchain, execute transactions on any network, and maintain its own secure state, all while operating under strong cryptographic guarantees.

WAVS provides the complete infrastructure layer: operator sets, restaker security, and operational orchestration. This means you can deploy your verifiable app quickly without the months-long bootstrapping headache that typically consumes development cycles.

Here's how it works

Watch for events anywhere: On-chain transactions, off-chain APIs, social media activity, IoT sensors, scheduled intervals. Any data source becomes a trigger for your application logic.

Execute complex logic: Run AI models, process real-time data streams, perform complex calculations that would be impossible or prohibitively expensive in smart contracts.

Submit results anywhere: Write to any blockchain (Ethereum, Solana, Cosmos, etc.), update traditional databases, trigger external APIs. All with cryptographic guarantees that multiple operators have verified the computation.

On a technical level, WAVS operates as a distributed event stream processor, like Kafka, for any blockchain environment or Web2 API. You can interact with data streams in a serverless-like environment, then submit verified results on-chain or to external services like MySQL databases or REST API endpoints.

What Apps Become Possible

Intelligent oracles: Real-time price feeds that aggregate from multiple sources, perform complex risk calculations, and adapt to market conditions. All verified by multiple operators rather than trusted to single data providers.

Autonomous AI agents: AI systems that can read blockchain state, make decisions based on complex on-chain and off-chain data analysis, and execute transactions across multiple chains with cryptographic guarantees that the logic was executed correctly.

Dynamic incentive systems: Reward mechanisms that track complex user behaviors across platforms, calculate sophisticated engagement metrics, and distribute tokens based on real-time activity verification.

Multichain applications: Bridges and protocols that transcend network tribalism, coordinating complex logic across different blockchains while maintaining state consistency and security guarantees.

Real-world integration: Applications that seamlessly blend on-chain blockchain infrastructure with off-chain traditional systems, enabling use cases that were previously impossible.

Build the Impossible

WAVS itself isn't where the value lies. It's what's created with it.

Whether you're developing the next generation of DeFi protocols, creating AI agents with blockchain integration, or building applications that were impossible under smart contract constraints, WAVS provides the foundation.

The code is open. The walls are gone. The network is yours to command.
