Entropy V2: Onchain Randomness Gets an Upgrade

Pyth Entropy delivers secure, onchain randomness to applications across more than a dozen EVM chains. Entropy is already powering games, raffles, prediction markets, NFT mints, and more—with 10 million randomness requests served to date.

Today, Entropy gets a significant upgrade.

Entropy V2 introduces a series of developer experience improvements, shaped directly by the feedback of teams using it in production: configurable gas limits for callbacks, adding callback statuses, and an upcoming public Entropy Explorer.

These upgrades reduce integration overhead, eliminate common failure modes, and offer greater control for developers.

This release is part of Pyth’s ongoing effort to empower builders to create new transformative applications by making core data infrastructure more open, reliable, and ready for use.

Built with Feedback, Ready for Production

Developers have made over 10 million randomness requests through Entropy. Entropy V2 introduces a number of significant improvements learned from our experience in this process:

Custom Gas Limits for Callbacks

Entropy now allows developers to set a custom gas limit when making randomness requests. This means teams can support more complex on-chain logic during the callback without worrying about exceeding the default gas cap.

Whether you’re assigning traits, rolling dice, or settling a market, you have more control over how randomness is used in your app.

Better Error Reporting

If your callback fails, you’ll now be able to see exactly why. V2 improves how failures are recorded on-chain, making it easier to identify issues and resolve them.

This reduces guesswork and makes Entropy safer and easier to adopt in production systems.

Improved Reliability

Entropy V2 introduces a more resilient callback architecture, adding an expanded keeper network which improves delivery guarantees.

This enhancement builds on the original design and enables requests to be fulfilled more reliably during unstable chain conditions.

Simpler Developer Experience

Entropy V2 streamlines the protocol so it’s even faster for developers to integrate. Simply call a function to request a random number, then get a callback with the result.

This change simplifies the integration flow, making it faster to prototype, test, and deploy applications using Entropy.

What’s Coming Next

In a few weeks, Entropy will introduce a new Explorer that gives developers insight into all randomness requests and callbacks across chains. It will show success and failure states, gas used, and reasons for any failed transactions.

These tools are designed to reduce integration time, eliminate friction, and make Entropy a default choice for any smart contract team that needs randomness.

The Role of Randomness in Open Systems

Entropy supports a key pillar of the Pyth mission: making critical data accessible to anyone who wants to build with it. While Pyth Price Feeds deliver structured market data, Entropy provides a different kind—data that’s random, verifiable, and secure.

Entropy helps unlock a different kind of fairness: one based on transparency, not trust. It allows developers to build applications where randomness isn’t a black box, but a verifiable part of the protocol. That’s a subtle but important step toward more open, secure, and transformative apps.

Get Started

Entropy is already powering randomness for projects like Infinex, Megapot, Junky Ursas, Ape Church, SankConnect, Capybara, and more. With V2, it’s even better equipped to support the teams shaping the next wave of on-chain experiences.

Entropy V2 is now live across supported EVM chains. No signup or permission required.
