Flow walkthroughs

End-to-end arcs, in the order most integrators implement them:

• Wallet whitelisting — register a minter wallet and activate its on-chain grant. The wallet must be active before you start a mint or burn flow.
• Onramp intent — fiat → crypto. Creates an intent, returns payment instructions.
• Offramp intent — crypto → fiat. Creates an intent, returns burn instructions.
• Burn signing — sign the burn in the user's wallet (Solana, Ethereum, Base or Polygon) and submit the proof back to Nora.
• Ethereum end-to-end — the whole Ethereum integration in one pass: whitelist, mint, burn, with real sandbox responses.
• Bridging BRS between chains — move BRS between Ethereum, Base and Polygon from the token contract, no API call.

Start with Core concepts if you haven't already — every flow relies on the same X-API-Key auth and idempotency-key conventions.
