Overview

Drop-in React hook + provider for LazorKit smart wallets on Solana. Users authenticate with a device passkey (Face ID, Touch ID, Windows Hello, security key) via the native navigator.credentials API — no popups, no extensions, no seed phrase.

Why this SDK

• Passkey auth — synced via iCloud Keychain / Google Password Manager for cross-device continuity.
• Gasless by default — Kora paymaster sponsors every mutation. Users never need SOL.
• Session keys — a single tap mints a scoped Ed25519 signer; subsequent txs are prompt-free.
• On-chain spending limits — optional lifetime caps, per-tx caps, recurring windows, program allow/block-lists.
• Ed25519 authorities — delegate admin / spender roles to companion keys.
• Deferred execution — one tap authorises multi-instruction payloads too big for a single tx.

The SDK talks to the passkey directly through the browser — no redirect flow, no portal window. Once signed, transactions are relayed by the Kora paymaster.
