Introduction

The Secp256r1 Native Program for verifying secp256r1 signatures. It takes a secp256r1 signature, a public key, and a message. Up to 8 signatures can be verified. If any of the signatures fail to verify, an error is returned.

Secp256r1 is an elliptic curve that enhances ECDSA signature verification efficiency. It improves compatibility with platforms like Android and iOS, supporting advanced wallet features and robust self-custody security.

Impact:

• Security: Strengthens wallet safety with dependable signature verification, reducing single-point failure risks.

• Compatibility: Elevates user experience for Solana mobile apps, ensuring seamless integration with modern technology.

About Lazorkit

Lazor.kit SDK is solution to integrate Passkey Authentication into the Solana ecosystem using a client-side and an on-chain program with Secp256r1 signature verification.

This enables secure, user-friendly login and transaction signing for Solana dApps via Passkeys (WebAuthn standards), ensuring cryptographic integrity.

Components:

1. Client-side SDK: Simplifies Passkey-based login and transaction preparation for dApps.

2. On-chain Program: Manages Passkey-derived PDAs and verifies Secp256r1 signatures for secure transactions

About the Track

We invite developers to build Solana dApps that integrate Passkey Authentication using Lazorkit for secure, user-friendly login and on-chain actions. Your dApp should:

• Enable Passkey-based login (WebAuthn) for users.

• Support secure transaction signing verified on-chain via Secp256r1.

• Integrate with one or more popular Solana dapps.
  For example: You can integrate Raydium, Jupiter, Meteora, Kamino, Marginfi, Zeta, Drift, Sling money, etc. to let user experience Solana DeFi without installing a wallet. You can also integrate Metaplex, MagicBlock, Honeycomb protocol for Gaming experience.

Objective : Deliver a modern Web3 experience that replaces seed phrases with Passkeys, aligning with authentication standards adopted by Apple, Google, and the FIDO Alliance.
