Tips & Tricks 💡 ✦ initApp({ dAppConfig: { nativeAuth: true } }) wires NativeAuth into the dApp SDK with sensible defaults. Pass a config object instead of true to customize origin, expirySeconds, or blockHashShard. ✦ LogoutManager auto-logs out users when their token expires. tokenExpirationToastWarningSeconds shows a warning before the logout fires — useful for letting users save work or refresh proactively. ✦ Backend verification needs the @multiversx/sdk-native-auth-server package, not the client. It does the signature check, the origin check, and the chain-state check against your gateway URL. ✦ extraInfo is signed into the token. Use it to bind additional context — a request scope, a tenant ID, a permission level — without trusting it to be reported client-side.

Meet the Tech: NativeAuth 🧩 The MultiversX-native authentication scheme — a signed token bound to a specific origin, a recent block hash, and an expiry, issued by a wallet and verified by an API. No password, no shared secret, no centralized identity provider. Proof of wallet control, time-bounded. Standard across MultiversX dApps and backend APIs. Wired into the dApp SDK and the JS SDK. 💡 🧵

Meet the Tech: Async Calls from Contracts 🧩 The protocol-level mechanism that lets one MultiversX contract call another, even when they live on different shards. Cross-shard calls are asynchronous by design — there's no synchronous return across the metachain. The framework gives you a typed surface over the async semantics. Initiate with async_call_and_exit, receive the response in a #[callback]. 💡 🧵

Moving value across shards usually means you handle the failures and reconciliation. On MultiversX the protocol guarantees it, both sides or neither. Live for five years, and Supernova is built to make it ten times faster.

Tips & Tricks 💡 ✦ ManagedAsyncCallResult is an enum: Ok(T) for success, Err(AsyncCallError) for failure. Pattern-match every callback — never assume success. ✦ Callbacks can receive captured state via #[callback_arg]. Pass the original sender, amount, or context through the call to use in the callback. ✦ Cross-shard latency is real. End-to-end async round-trip is roughly three block times. On Supernova's 600ms target clock, that's ~1.8s; on the legacy 6s clock, ~18s. Design the user-facing flow around it.
