Congratulations

You finished the Solana track. That's a real milestone. You went from "programs are stateless and accounts hold everything" to writing real Anchor programs, composing them through CPI, integrating Token-2022 extensions, and deploying the kind of code that runs on the second-largest smart-contract platform by total value locked (TVL). The Solana model is harder to start than Solidity, and you got past that part. The fluency is yours now.

Take a moment to appreciate what you've built. Everything you learned here is the foundation every program you'll ever read or write sits on. It doesn't expire. It gets sharper the more you use it.

The Ethereum track is the natural next step if you haven't taken it yet. You'll write Solidity against a different account model and a different execution environment. Most of the security instincts you built here transfer. Reentrancy on Ethereum follows the same pattern as CPI misuse on Solana — the mechanics differ, but the underlying vulnerability is the same. The EVM's storage layout is easier to understand once you have already worked through rent and zero-copy.

If you have already completed the Ethereum track or are not interested in learning another platform, keep building on Solana. Pick a protocol you like and read its on-chain program end to end. Read Jupiter's router. Read a Drift or Kamino vault. Build something of your own. Apply for an audit role. There's plenty of work for the kind of person who can do what you can now do.

Whatever you pick next, good work getting here.
