Adelos Registry - Anchor Smart Contract

Solana smart contract for managing identity registry in the Adelos Protocol.

📋 Overview

The Adelos Registry stores user identities with their meta public keys. This enables senders to derive unique stealth addresses for private transfers.

🏗️ Program Structure

#[account]
pub struct RegistryAccount {
    pub owner: Pubkey,          // Owner's wallet address
    pub meta_pubkey: [u8; 32],  // Ed25519 meta public key
    pub bump: u8,               // PDA bump seed
}

Space: 8 (discriminator) + 32 (owner) + 32 (meta_pubkey) + 1 (bump) = 73 bytes

📝 Instructions

Instruction	Description	Signer
register_identity	Create new registry with meta_pubkey	Owner
update_identity	Update existing meta_pubkey	Owner
close_registry	Close registry and reclaim rent	Owner

Register Identity

// Create and send register transaction
const tx = await sdk.createRegisterTransaction(ownerPubkey, metaPubkey);
const signedTx = await wallet.signTransaction(tx);
await sdk.sendAndConfirm(signedTx);

Update Identity

// Update meta pubkey (e.g., after wallet recovery)
const tx = await sdk.createUpdateTransaction(ownerPubkey, newMetaPubkey);
const signedTx = await wallet.signTransaction(tx);
await sdk.sendAndConfirm(signedTx);

Close Registry

// Close registry and reclaim rent (~0.002 SOL)
const tx = await sdk.createCloseTransaction(ownerPubkey);
const signedTx = await wallet.signTransaction(tx);
await sdk.sendAndConfirm(signedTx);
