We are thrilled to announce the release of Polygon Supernets' latest test version, v0.9, which marks a significant milestone for the development team and the larger Polygon community. This planned release line is crucial to the upcoming v1.0 production release as the product suite matures and approaches its production-ready state.

It's essential to keep in mind that these test releases will include breaking changes and offer no guarantees, including backward compatibility. You should use the current test releases for testing and familiarization only. A comprehensive source code audit is underway.

Note that the v0.9 release is not yet backward compatible with previous versions of Polygon Supernets, and migration support will be introduced in future releases.

Notable features of Polygon Supernets v0.9 include:

• Expanded allowlists and transaction blocklists
• Staking and token separation support
• NFT bridge support
• Transaction fee management
• Deployment optimizations and improvements to the Genesis workflow

Let’s dive in!

The MVP Release: Testing the Future of Decentralized Applications

The v0.9 release introduces new core contracts and consensus client primitives, bringing Polygon Supernets closer to realizing the vision of creating "Super networks." These networks embody unparalleled scalability and sovereignty facilitated an associated rootchain. 

Notably, the protocol has advanced to its MVP stage, which includes the following key updates:

• Expansion of allowlists to include bridge transactions and transaction blocklists
• Support for staking MATIC on the rootchain
• Separation of staking, rewards, and gas token to allow for payment with different tokens
• Bridge support for ERC-721 and ERC-1155
• EIP-1559 support
• Improvements to the Genesis workflow
• Removal of application-specific configuration using the Manifest and other deployment optimizations

Access Management: Expanded Allowlists & Transaction Blocklist

This release expands the existing allowlists, supporting both on-chain and cross-chain (bridge) transactions. Additionally, a new transaction blocklist is introduced to enhance security.

These features empower users with heightened control over their blockchain operations, enabling them to manage specific transactions or addresses and ensure compliance while mitigating security risks.

Unlocking the Full Potential of Your Tokens: Staking, Token Separation, & EIP-1559 Support

This release brings forth the official introduction of MATIC staking on the rootchain. Users can also leverage the new token flexibility features to configure rewards for their chain using the native token or any other ERC-20 token.

The separation of staking, rewards, and gas token payments further allows for payment with different tokens, simplifying asset management and reducing costs. Moreover, Polygon Supernets now supports EIP-1559, an Ethereum improvement proposal that improves transaction fee management and establishes a more efficient and predictable fee market.

Additionally, it is worth noting that the rewards wallet can be assigned separately from the validators, providing even more flexibility to users.

NFT Interoperability: Unlocking Possibilities with ERC-721 & ERC-1155

The native bridge supports the ERC-721 and ERC-1155 asset standards. This enables developers to seamlessly integrate these standards into their sovereign chains, unlocking a wide array of opportunities for NFT interoperability.

Bridging the Gaps: No More Non-Bridge Deployments

In this release of Polygon Supernets, the distinction between "bridge mode" and "non-bridge mode" deployments has been eliminated. The bridge is now an integral part of the product suite and is configured by default.

Deployment Clean-Up: Streamlined Genesis Workflow & No More Manifest.json

This update removes application-specific configuration via Manifest.json, streamlining deployment and reducing errors. The Genesis workflow has also been improved, making it easier for developers to create custom chains that meet their specific needs.

Break and Verify: Ensuring Compliance & Security Through Audits & Testing

Lastly, a comprehensive source code audit is underway to ensure the Polygon Supernets product suite's security and reliability. Any issues found during the audit will be addressed before the official release.
