The Great Migration Nobody Talks About
Here's what actually happened: Foundry performance numbers started getting too good to ignore in 2024, but most teams were hesitant to migrate until they had no choice. I watched this shift happen across multiple projects - first the individual devs started experimenting, then entire teams made the jump.
Last year, I was maintaining a DeFi protocol that took about 6-7 minutes to run its test suite on Hardhat. I had this whole fucking routine - start the tests, make coffee, check Slack, sometimes answer emails, and usually the tests were still running when I got back. When I finally said fuck it and ported everything to Foundry, same exact tests ran in 31 seconds. I timed it. Point is, I stopped making coffee during test runs.
The 2024 Solidity Developer Survey confirmed this trend - Foundry overtook Hardhat as the most popular framework with 51.1% of developers, marking a massive shift from JavaScript to Rust-based tooling.
Why Teams Actually Switch (Spoiler: It's Not What You Think)
Everyone talks about Foundry's speed, but that wasn't the killer feature for our team. It was writing tests in Solidity instead of JavaScript. No more context switching between languages. No more wrestling with ethers.js type definitions that never match reality.
Hardhat still owns enterprise for one reason: most senior devs learned JavaScript before they learned Rust. The JavaScript ecosystem is massive, battle-tested, and boring. That's actually a feature when you're managing serious money.
But here's the thing nobody mentions in those framework comparison blogs: Truffle is fucking dead. I've seen exactly zero new projects start with Truffle in 2025. ConsenSys officially sunset the entire Truffle Suite in 2024, and any dev still recommending it is either maintaining legacy code or hasn't kept up. It's in maintenance mode, which is enterprise-speak for "we're not fixing anything unless it's literally on fire."
The Multi-Chain Reality Check
Multi-chain support sounds great until you actually try to deploy to five different networks and realize each one has its own quirks:
- Polygon gas estimation is weird
- Arbitrum has different precompiles
- Optimism sometimes doesn't propagate transactions
- Avalanche C-Chain acts like Ethereum until it doesn't
Foundry handles most of these better than Hardhat, but you'll still spend weekends debugging shit like "transaction underpriced" errors that only happen on Arbitrum during high gas periods. That specific error cost us a 6-hour debugging session before we realized their gas estimation is just broken sometimes.
The Solana Exception
Anchor isn't competing with Ethereum frameworks - it's solving completely different problems. Solana's account model is so alien compared to Ethereum that you need specialized tools. I spent three months learning Anchor and it felt like learning blockchain development all over again.
The performance claims are real - Solana can actually handle real user volume. But the developer experience is rough. Error messages are cryptic, debugging tools are limited, and the whole ecosystem feels like Ethereum circa 2018. Getting started with Anchor requires a completely different mental model.
What This Means for Your Next Project
Choose Foundry if you're starting fresh and can handle Rust. Choose Hardhat if you have JavaScript developers who need to ship fast. Skip Truffle unless you're maintaining legacy code.
That's it. Everything else is overthinking.
