ShimmerEVM test chain has been launched on the Shimmer Testnet, opening up a new world of possibilities for blockchain developers.

In this thread🧵, I will summarize the key features of the launch.

Let’s dive in👇🏼

What I will be covering in this thread:

-ShimmerEVM expands the reach of Shimmer protocol
-Network security is crucial
-Public testnet phase
-Consensus refactor

-Historical state
-Extended EVM functionality
-Brand new API
-Conclusion

ShimmerEVM expands the reach of Shimmer protocolWhat I will be covering in this thread:

ShimmerEVM, which is an EVM chain on the Shimmer testnet, is a major step forward in expanding the reach of the interoperable and scalable Shimmer protocol to a broader community of #blockchain users and developers who build EVM-compatible smart contracts.

The chain enables seamless and bridgeless native asset transfer between Shimmer L1 and EVM chains, which will form the basis for extended EVM compatibility.

Network security is crucial

Given the importance of ShimmerEVM for the @shimmernet and @iota ecosystems and the fact

that tokens worth hundreds of millions of dollars will be exchanged, traded, and bridged from other networks to the #Shimmer network, the team invested extra time to ensure the security of the network.

Refactoring of the codebase, several audits, and countless hours of internal testing were crucial to be confident about the network's stability and safety.

Public testnet phase

In this public testnet phase, the Shimmer team will further test and validate the ShimmerEVM, helping to find bugs or improvements to be made. This will help expedite the launch of ShimmerEVM on the #Shimmer network in production.

Consensus refactor

The biggest change in Wasp, the smart contracts node implementation, since its last release has been a major refactoring of the consensus-related modules.

The consensus modules enable a group of validators (the committee) to form a consensus (agreement) without having to assign a leader to decide on what the next state update of the smart contract chain will be.

This change took quite a bit of time but is crucial given the complexity of the consensus modules.

Historical state

The node software also supports looking up the historical state of smart contracts and not just the most recent state.

This is now implemented on both ISC and EVM levels and allows proper block explorer and indexation services on EVM chains, which was not previously possible.

Extended EVM functionality

EVM compatibility also received an upgrade, adding convenient support for using Shimmer native assets from L1 on an EVM chain as if they were ERC20 tokens (for native assets) or ERC721 NFTs (for L1 NFTs).

The Shimmer team implemented several interfacing contracts that allow native assets deposited to a chain to be used directly within EVM without losing the flexibility to seamlessly transfer those assets back to L1 if desired.

Brand new API

The launch also includes a brand new API used by a new dashboard and CLI implementation, providing developers with the details needed to use this new functionality.

The @shimmernet team will continue to make improvements to the developer experience of this functionality over the next few weeks.

Conclusion

The launch of the ShimmerEVM test chain on the Shimmer Testnet expands the reach of the Shimmer protocol to more blockchain users and developers who create EVM-compatible smart contracts.

Improvements to the node software, consensus refactor, historical state lookup, extended EVM functionality, and new API help ensure network security, reliability, and recoverability.

This public testnet phase is vital to identifying bugs and expediting the launch of ShimmerEVM in production.
