Wallets and Keypairs

Keypair provides device-side wallet operations for Solana.

Common Operations

• Generate a random keypair.
• Import from Base58 private key.
• Import from seed bytes.
• Export public key as Solana address.
• Sign and verify payloads.

Example

Keypair wallet;
wallet.generate();
 
char address[64];
wallet.getPublicKeyAddress(address, sizeof(address));
Serial.println(address);

Security Guidance

• Never hardcode production private keys in firmware.
• Avoid logging private key bytes to serial output.
• Use secure storage strategy for production devices.
• Rotate keys used in test and staging fleets.
