Generating and Preparing the Secret Key

2 мин. чтения

🔐 In some wallets (such as OKX), the private key is stored in base58 format, especially for EVM networks. For Solana, base64 format is used, and it must be obtained separately.

🔑 How to Get the EVM Private Key from OKX #

  1. Open the OKX WALLET app and go to Wallet Settings.
  2. Select Manage Wallets — find your wallet (e.g. “CRYPTA”).
  3. Tap the ⋮ (three dots) next to the wallet name → Seed Phrase — save it in a secure place.
  4. In the Account section, locate the desired wallet (e.g. DEXBOT) and tap on it.
  5. Tap on Private Key — the private key in base58 format will appear (starting with 0xd...).
  6. Important: when adding the key to your .env file, remove the 0xd prefix. For example:
    WALLET_SECRET_KEY=abcdef1234...

🧩 How to Get Solana Private Key (base64) #

  1. Use your base58 key or your seed phrase (mnemonic) obtained from OKX or another wallet (such as Phantom or Trust Wallet).
  2. Open the terminal and navigate to the folder containing the file:
    cd ./MYBOTS
  3. Give the file execute permission if needed:
    chmod +x keyall.bin
  4. Run the file:
    ./keyall.bin
  5. Select language (1 – Russian, 2 – English).
  6. Select the source of the key:
    • 1. From Seed Phrase – enter 12 or 24 words (space-separated)
    • 2. From Base58 – enter the private key in base58 format
    • 3. From DEC Array – enter comma-separated numbers (e.g. 174,47,154,…)
  7. The program will show:
    • Solana Public Address
    • Private Key in Base58
    • Private Key in Base64 (this is what goes into .env)
    • DEC and HEX representations
  8. Copy the Base64 value into your .env file:
    SOLANA_SECRET_KEY=ndLVItNzBQ9Qr7kqglMu...==

🔐 How keyall.bin works #

  • The program uses base58, base64, and solders libraries to convert keys.
  • Supports three input methods:
    1. Seed Phrase – converted to seed bytes via BIP39, then to Solana key
    2. Base58 – directly decoded into private key
    3. DEC Array – number list converted to bytes, used to generate key
  • If you have Python, you can install the required dependencies and simply run keyall.py — it’s located in the main folder.
  • The keyall.bin version is a standalone binary that works without any dependencies.

🗒️ Example: .env file structure #

WALLET_SECRET_KEY=abcdef1234...  # EVM (without 0xd)
SOLANA_SECRET_KEY=ndLVItN...==  # Solana (base64)

❗If you see a base58 key, it’s EVM, not Solana #

  • For Solana, you need a base64 key from a seed phrase or convert base58 using the keyall.bin tool.
  • Base58 keys cannot be used directly — Solana uses Ed25519 + base64 format.
