Top up SOL, mint mock tokens.
Walk through the dapp end-to-end on Solana devnet without spending real money. The faucet is rate-limited per Solana’s public RPC.
1 SOL
Drop one devnet SOL to the connected wallet. Plenty for hundreds of looper signatures at Solana mainnet fee-floor pricing.

SOL airdrop hits Solana’s public devnet RPC (rate-limited — fall back to faucet.solana.com). Mock token mints route through /api/faucet; that API needs the deployer keypair on the server (set via COIL_FAUCET_KEYPAIR env). On the production Vercel deploy this isn’t configured yet; pre-loaded wallets used in the recording still work because the Mac Mini deployer minted directly into them.
§05
Out of SOL?
If the public devnet faucet rate-limits you, two backups work:
- faucet.solana.com ↗ — official, web-based, slightly higher quota than the RPC.
- helius.dev/airdrop ↗ — third-party, drops to a custom RPC if you have one.
Once you have SOL and mock STRC, run the smoke test on /positions — “Initialize the demo vault” calls the Wrapper instruction end-to-end.
