Solana Blinks (Axum) Community Template

This PR adds a new community template for building Solana Actions/Blinks using Rust with the Axum web framework and a Next.js testing frontend.

What's included

• Three example actions - SOL transfers, a donation flow with action chaining (transfer + on-chain memo), and a swap placeholder ready to wire up to
  Jupiter/Raydium
• Action chaining - Stateless multi-step flows using URL-encoded chain state, no server-side storage needed
• Testing frontend - Next.js web UI for testing action endpoints locally
• Production ready - CORS (required by the Actions spec), tracing, structured error handling, and environment configuration built-in
• Zero-config development - cp .env.example .env && cargo run to start

Files added

• community/solana-blinks-axum/ - Complete template with Axum server, three example actions, action chaining, and Next.js frontend

Files updated

• templates.json - New template entry
• .github/workflows/templates.json - Added to CI workflow
• TEMPLATES.md - Template documentation
• pnpm-lock.yaml - Workspace entry

Installation:

npx create-solana-dapp my-project --template solana-blinks-axum

The setup instructions guide users through starting the Rust backend and the Next.js frontend in separate terminals.

@cxalem can you check this one. Looks interesting!

Reviewing this now!

The frontend is pointing to devnet but this defaults to mainnet! Would be cleaner to default to devnet here too so everything matches out of the box!

@cxalem this is done!
