Last week, I shared what @Neon_EVM is and how it lets you run Ethereum contracts on Solana. But here's one other thing that really caught my attention during the bootcamp: how they solved the token compatibility problem. It was one of our first lessons and I'm glad it was. Let me explain ERC-20-for-SPL... Picture this scenario: You have USDC on Solana (an SPL token), but you want to use it in an Ethereum dApp that's deployed on Neon EVM. Traditionally, you'd need bridges, wrapped tokens, or complex asset transfers. Not ideal. Neon EVM solved this with something called ERC-20-for-SPL — and it's honestly brilliant. Here's how it works: ERC-20-for-SPL is basically a translation layer. It takes native Solana tokens (SPL) and makes them look like ERC-20 tokens to Ethereum contracts. But here's the key part — there's NO manual bridging or wrapping. Your USDC stays as native SPL USDC on Solana. The ERC-20-for-SPL contract just provides an ERC-20 interface that points to your actual SPL token balance. Think of it like this: You have money in a US bank account, but you get a card that works in European ATMs. Same money, different interface. What this means practically: ✅ No liquidity fragmentation ✅ No wrapped token risks ✅ Native Solana token benefits (speed, low fees) ✅ Full ERC-20 compatibility for dApps During the bootcamp, I saw this in action. I could use my devnet SPL tokens directly in Ethereum smart contract interactions without any token swaps or bridges. When you call an ERC-20 function (like transfer), it maps to operations on your Solana Associated Token Account (ATA) behind the scenes. This is what makes @Neon_EVM special. Its not just running Ethereum contracts on Solana, it's creating a unified token experience across both ecosystems. Next, I’ll share the dApp I built for my graduation project. Not a big use case. I could’ve done more, but due to my schedule I had to settle for something simple. Still, it made use of ERC-20-for-SPL and honestly, this kind of composability is what the multi-chain future should feel like.
