Server-side Solana signature checks do not need the full web3 stack. Decode the address to public-key bytes, encode the signed message, and verify the detached signature with a narrow ed25519 library.

In current Next.js route handlers, dynamic params can arrive as a Promise. Treat them as async input at the boundary and unwrap before reading fields.

Small utility packages can change CommonJS and ESM behavior between majors. Imports that cross that boundary should be checked against the installed version, not copied from memory.

The v4 setup starts from @import "tailwindcss". Stable component classes are still useful when the UI needs exact rhythm instead of a long utility chain.

Browser wallets expose the same general actions, but result shapes and globals vary. Normalize the signed message result before sending it to the API.

Counters and vote updates should happen in one database-side operation. Read, modify, write from the client is a race waiting to show up under load.

If a page depends on the latest file contents, read inside the request path and mark the route dynamic. Module-scope reads are easy to accidentally freeze.
