Solana

1/ Every Friday, we ship something to make building with Privy simpler and better.

Today: Solana policy engine 🛡️

Control how your app interacts with Solana with programmable policies: by account, program, or instruction.

Here’s how it works 🧵

4/ Solana policies let you tailor access rules by user or wallet, helping you:

→ Set different permissions for power users vs new users
→ Create granular controls at the program or instruction level
→ Add a security layer before signing occurs

3/ A few example policies you can now set:

🧱 Only allow interactions with an allowlist of programs
🎯 Restrict swaps to just Jupiter or Raydium
🚫 Block certain token transfers (e.g. known scam assets)
🔒 Require approval for large txs

2/ With Solana policies, you can:

✅ Allow or deny specific programs
✅ Filter by instruction type
✅ Control access at the account level
✅ Block unknown or suspicious txs
✅ Define policies per user or wallet

All enforced before signing happens.

This is such a win for Solana builders… real security controls without killing speed 🔥
