Bitfinity’s EVM Toolkit Quietly Raises the Bar

There’s a quiet shift underway for developers with an eye on Bitcoin and a taste for Ethereum’s toolbox. Bitfinity has been shaping itself into a Bitcoin Layer 2 chain with full EVM compatibility, and instead of thundering announcements or flashy taglines, it’s letting its tech stack do the talking.

Developers exploring Bitcoin’s possibilities have long faced a trade-off—raw security and simplicity on one side, and the developer-friendly, richly tooled EVM experience on the other. Bitfinity seems to be bridging that gap with purpose-built integrations that borrow wisely from the Ethereum ecosystem while sticking to Bitcoin’s foundational ethos.

A good place to start is Foundry. This one’s gained traction for a reason. Written in Rust, it’s an EVM toolchain tailored for thorough testing, and Bitfinity has woven it into its framework to test core components of its architecture. It’s not just the base chain that benefits. Smart contracts built on Bitfinity can take Foundry’s full suite out for a spin, making protocol testing smoother and more exhaustive than it might otherwise be. If you’ve been anywhere near EVM dev in the last year, you’ve likely heard developers raving about Foundry’s clean CLI, fuzzing options, and speed. Bitfinity’s decision to double down on it is less about being trendy and more about getting things done fast and properly.

Then there’s the use of Parity-tech’s Patricia Merkle Trie. This isn’t a name that gets thrown around casually, unless you’re steeped in Ethereum’s inner workings. Bitfinity has adapted PMT to suit the specific contours of its chain. That choice says a lot. PMTs are central to how Ethereum manages state and ensures efficient proof verification, and tweaking it to fit a Bitcoin-based L2 means Bitfinity isn’t interested in off-the-shelf solutions—it wants the ones that match its architecture. It’s this trie that powers Bitfinity’s canister storage system, which is no side feature—it’s a core part of the infrastructure.

Speaking of canisters, the Bitfinity Canister SDK deserves its own spotlight. If you’ve worked on the Internet Computer (IC), you already know the term. Bitfinity’s SDK builds on existing frameworks like ic-cdk and ic-kit, offering new abstractions that make the business of building, testing, and deploying canisters more straightforward. For those unfamiliar, canisters are a kind of smart contract unique to the IC ecosystem, and Bitfinity’s decision to integrate them suggests a broader compatibility vision beyond Ethereum. It’s not just about mimicking Solidity—Bitfinity wants to enable structured, robust apps using Rust, with tooling that’s open-source and tightly engineered. That means faster iterations, cleaner integrations, and fewer late-stage surprises for teams moving from prototype to production.

To run all this efficiently, you need a core that can handle serious workload with speed. That’s where REVM enters the picture. Short for Rust Ethereum Virtual Machine, it’s a high-performance EVM engine built with speed in mind. Bitfinity chose REVM as the processor for its EVM layer, essentially the beating heart of smart contract execution. The choice of REVM makes sense not just for its performance profile, but also for its code clarity and growing developer mindshare. Running contracts at scale without choking the chain? That’s REVM’s job, and it’s one Bitfinity clearly wants done right.

Put all these pieces together, and what you’ve got is a setup that’s quietly ambitious. There’s no noise about revolution or reinvention, just a series of deliberate, smart engineering decisions aimed at delivering what devs want—EVM compatibility, Bitcoin security, and a toolchain that doesn’t get in the way. It’s early days still, but Bitfinity seems to be courting the kind of builders who want to get to work without waiting around for someone else to smooth out the technical edges.

The question it raises is simple: what happens when more Bitcoin-native projects start to look like this? EVM compatibility is no longer a novelty—it’s table stakes. But doing it well, with the right mix of performance tools and developer experience, is another matter. Bitfinity is banking on a modular approach, where best-in-class open-source components are adapted, not just adopted. It’s a method that rewards precision over hype.

There’s also the broader implication of this setup: bridging Bitcoin and Ethereum development doesn’t need to mean abandoning the strengths of either. Bitfinity isn’t rewriting what it means to build on Bitcoin. It’s just making that experience faster, smoother, and closer to what devs have come to expect in EVM environments. The friction drops, the velocity rises.

For developers considering where to launch their next project, especially those eyeing the security of Bitcoin and the agility of Ethereum tools, this kind of hybrid approach is starting to make more sense. It’s not about favouring one camp over the other—it’s about building where you can iterate faster without sacrificing performance or predictability.

Bitfinity’s toolkit sends a message, loud enough for those paying attention. If you want to build on Bitcoin and bring your EVM skillset along, the door’s not just open—it’s well-oiled. And while the ecosystem around L2s continues to expand, what separates the promising ones from the pack is often what’s under the hood. Bitfinity’s not shouting, but it’s making sure its engine’s built for the long haul.

For those ready to start building or just curious about what a high-speed Bitcoin L2 with full EVM chops looks like, Bitfinity might be the next place worth watching. Or better yet—testing.
