Generate Solana Address

Derive a deterministic Solana address from an MPC key share. Solana uses Ed25519 keys — the address is the base58-encoded raw public key.

Components used:

• GET_SOLANA_DERIVATION_PATH — produce a BIP-44 path (m/44'/501'/account'/change')
• COMPUTE_PUBLIC_KEY — derive the Ed25519 public key from the key share at that path
• COMPUTE_SOLANA_ADDRESS — convert the public key to a base58 Solana address

Code

import { WorkspaceClient, ComponentModule } from 'caller-sdk';

const workspace = new WorkspaceClient({ apiKey: process.env.WR_API_KEY! });

async function generateSolanaAddress(keyId: string, accountIndex: number): Promise<string> {
  // 1. Build BIP-44 derivation path for the given account
  //    Phantom/Solflare style: m/44'/501'/accountIndex'/0'
  const { derivationPath } = await workspace
    .call(ComponentModule.GET_SOLANA_DERIVATION_PATH, {
      accountIndex,
      changeIndex: 0,
      addressIndex: null, // 4-level path (Phantom/Solflare style)
    })
    .promise();

  // 2. Derive the Ed25519 public key from the MPC key share
  const { publicKey } = await workspace
    .call(ComponentModule.COMPUTE_PUBLIC_KEY, { keyId, derivationPath })
    .promise();

  // 3. Convert the public key to a Solana address (base58)
  const { address } = await workspace
    .call(ComponentModule.COMPUTE_SOLANA_ADDRESS, { publicKey })
    .promise();

  return address;
}

// Example: derive first Solana account address
const address = await generateSolanaAddress('your-key-id', 0);
console.log('Solana address:', address); // base58 string

Derivation path styles

Style	Inputs	Path
Phantom / Solflare (4-level)	accountIndex: 0, changeIndex: 0, addressIndex: null	m/44'/501'/0'/0'
Ledger / CLI (5-level)	accountIndex: 0, changeIndex: 0, addressIndex: 0	m/44'/501'/0'/0'/0'

Use the 4-level path for compatibility with Phantom and Solflare wallets.
