The blockchain space is evolving, and while scalability concerns are gradually fading, the focus has shifted toward improving how developers and users interact with smart contract platforms. Currently, most blockchains are locked into a single virtual machine (VM) environment, limiting the flexibility for both developers and users. But what if there was a way to combine the strengths of different VMs into one cohesive experience?

Enter Fluent — the first blockchain to unify multiple VMs into a seamless, interoperable execution environment through a revolutionary concept called Blended Execution.

The Problem with Single VM Execution

Today, most blockchains support only a single execution environment tied to a specific VM, such as Ethereum’s EVM (Ethereum Virtual Machine) or Solana’s SVM (Solana Virtual Machine). This restricts developers to a single set of tools, programming languages, and execution paradigms.

For example, if you’re developing on the EVM, you may benefit from its vast tooling ecosystem but miss out on the parallel execution efficiency of Solana’s SVM. Likewise, moving between chains requires bridging assets, dealing with different wallets, and managing various token standards — all of which create friction and expose users to additional security risks.

In essence, developers are forced to choose between isolated ecosystems, and users bear the brunt of it.

Blended Execution: A New Paradigm

Blended Execution introduces a novel solution to this fragmentation by enabling apps from multiple VMs to run on the same network, treating them all as first-class citizens. With blended execution, developers can mix and match the best features of different VMs to build more powerful, flexible applications. This opens up exciting possibilities for composability between applications built on different VMs.

Think about it: A smart contract written in Solidity could seamlessly interact with a program written in Solana’s Rust — without the need for bridging or switching wallets. It’s a whole new level of interoperability.

Fluent: The First Blended Execution Network

Fluent is at the forefront of this transformation, blending multiple VMs — including EVM, Wasm, and soon SVM — into one unified network. This Ethereum Layer 2 (L2) enables developers to deploy contracts written in various languages like Solidity, Rust, and TypeScript, without the friction typically associated with moving across different ecosystems.

• Seamless Composability: Apps from different VMs can now coexist and interact in real-time. Developers no longer need to choose between ecosystems; they can tap into the strengths of each one.

• Diverse Tooling: By unifying different VMs, Fluent empowers developers to leverage the best tools across various ecosystems. Want to build a financial app using Solidity but need Rust’s efficiency for parallel processing? Fluent makes it possible.

How Fluent Makes It Work

At the core of Fluent’s blended execution is a system that allows contracts from different VMs to communicate and interact synchronously. Each VM on Fluent is represented by a Wasm-based compatibility contract that defines execution standards and APIs.

For example, when a Solidity contract wants to call a Solana Rust contract, it references the SVM compatibility contract. This happens in a single, atomic transaction — meaning no bridges, no multi-step processes, and no fractured user experience.

Fluent compiles everything down to its own modified version of WebAssembly called rWasm. This system is optimized for zero-knowledge (zk) operations, ensuring secure, efficient cross-VM interactions.

Why Blended Execution Matters

Blended Execution doesn’t just unify virtual machines — it unifies the blockchain experience. Developers can access a broader set of tools, languages, and libraries, while users get seamless interactions without worrying about network switches or fragmented ecosystems.

For developers, it’s a game-changer. You can now build microservices-like applications using the strengths of multiple languages. For users, it’s all about frictionless interactions — no more swapping between wallets or bridging between networks.

Wrapping It Up

Fluent is pioneering the blended execution era, where different VMs collaborate in a single environment, breaking down the silos that currently exist between blockchain ecosystems. This is the next logical step in blockchain’s evolution — uniting the best features of Wasm, EVM, and SVM in a way that enhances developer experience and broadens the possibilities for users.

As the first network to offer this level of interoperability, Fluent is setting the stage for the next phase of decentralized applications. Blended Execution isn’t just a technical upgrade — it’s a paradigm shift. Stay tuned as Fluent continues to expand, making blockchain more unified, efficient, and powerful than ever before.
