Do Python Developers Need Solidity, Rust, or Golang for Web3 Jobs Abroad in 2025?

I also started in Python and made the move into blockchain. What worked for me was focusing on Solidity first. Most jobs expect you to know Ethereum and DeFi basics inside out. In interviews, they’ll ask things like: “show me how reentrancy happens” or “how do you cut gas costs here?” That’s where they judge if you’re serious.

Rust is useful, but only if you’re aiming for Solana or Polkadot. If you’re just starting out, concentrate on Solidity until you try a few small projects. 

Forget about certificates. Nobody has asked me for one. What they look at is your GitHub. Don’t leave it full of just Python. Add small Solidity repos like a simple ERC20 or ERC721, a contract with a reentrancy bug and the fix, some gas benchmarks.

Keep them short, explain what you did in the README, and pin them. That’s enough to show you’re learning the right things.

For jobs, I see the most action in Singapore, UAE, and Switzerland. The US is strong but harder to crack without a network. LinkedIn is slow; I found more leads on Twitter and in L2 Discords like Arbitrum and Optimism. A lot of teams post there before anywhere else.

If you want to stand out, take a protocol you like, review one contract, and share your notes. Even a short write-up gets noticed.

If you’ve been coding in Python and want to move into blockchain, start by looking at places where the demand is strong. Right now, the US, Germany, and Singapore have plenty of opportunities.

Don’t wait for a perfect project to show up. Build something small that connects Python with blockchain — maybe a DeFi tool, maybe a supply chain tracker. Even a side project can say a lot about how you solve problems. Write down what you tried, what worked, and what didn’t. That becomes your portfolio.

On LinkedIn, don’t just say “learning blockchain.” Share what you’re actually doing — a bug you fixed, an insight about gas costs, or your notes from a contract you studied. That kind of content gets more attention than generic updates.

And definitely hang out where blockchain devs actually talk: Discord servers, Slack groups, and local meetups. Most opportunities come through people you know, so the more you show up in those spaces, the easier it gets to find global roles.

I’d add my two cents. Since you already have 8 years of Python experience, don’t underestimate your valuation in blockchain industry especially for scripting, testing, and building tools around smart contracts. A lot of teams need Python devs for off-chain infra (indexers, bots, analytics dashboards), and that can be your bridge into deeper on-chain roles.

For showing blockchain skills on GitHub: mix your Python repos with Solidity utilities. For example, write a Python script that interacts with your own ERC20 contract (mint, transfer, query balances). That demonstrates you understand both ends, contract logic and how dApps actually consume it. Recruiters love seeing that kind of integration project.

As for countries: Singapore, Switzerland, and UAE are hot for protocol jobs, but I’ve also seen Germany and Portugal attract strong dev talent. US is big but visa hurdles are also big.

Rust/Golang only matter if you specifically target ecosystems like Solana, Polkadot, or Cosmos. If your first goal is “get hired abroad,” double down on Solidity + Python tooling. Once you’re in, you can branch into Rust.
