When migrating to another wallet provider or as a last-resort recovery option, you can use key export. Key export reconstructs a standard private key from your MPC key shares and lets you download it for use in any wallet that supports private key import.
Key export is a high-risk operation. A reconstructed private key gives full, unilateral control of your funds to anyone who possesses it — the MPC protections that normally prevent any single party from acting alone no longer apply. Only export in a private, offline environment, and only when necessary.

​
What gets exported

Key export reconstructs the complete private key from your MPC key shares. The result is a standard private key — not an MPC key share — and can be imported into any wallet that supports standard private key import.

​
Before you begin

  • Ensure you are in a private environment with no screen sharing, remote access, or observers
  • Have a secure offline storage location ready (encrypted USB drive or external hard drive)
  • Your Cobo wallet remains fully functional after export — both the exported key and your Cobo wallet control the same addresses, so any transaction made with either affects the shared balance

​
How to export your private keys

1

Open key export

In the Cobo Agentic Wallet app, go to Account > Wallet Management, tap the … icon beside your wallet name, and tap Export Private Keys.
2

Export your key

Follow the instructions on the screen to complete the export.
3

Save your key

Copy the key and paste it into a file, or download the CSV file directly. Store it offline only — on an encrypted USB drive, external hard drive, or another physically secure location.
Do not store the exported key in cloud storage, email, or any internet-connected location.

​
After export

Once you have finished using the exported key:
  • Do not retain copies in any location you do not physically control
  • If you believe the exported key was exposed or compromised at any point, treat all funds in the affected addresses as at risk and move them to a new wallet immediately

​
Importing into another wallet

Each address in the exported CSV has its own private key. Import is done at the address level — select the specific address key you want to import. EVM and Solana keys are separate and not interchangeable; make sure to import each key into a wallet that supports its chain type.

​
EVM chains

Import steps vary by wallet provider. In general:
  1. Select the address key you want to import from the exported CSV
  2. Import it into a non-custodial wallet that supports the corresponding chain
  3. Verify the imported address matches your original

​
Solana

Solana uses a different key derivation standard from EVM chains. The private key exported for Solana addresses is a raw Ed25519 scalar — it is not in the standard seed format expected by most Solana wallets (such as Phantom or Solflare), so direct import into those wallets is not supported. To move funds from an MPC-exported Solana address, use the open-source ucw-eddsa-signing tool, which signs Solana transactions directly from the scalar. Steps
  1. Export your private key via caw export-key or the Cobo Agentic Wallet app. The exported CSV contains a private_key column with the scalar in hex for each Solana address.
  2. Run the tool. To sign a message: 
    ./ucw-eddsa-signing sign --key <scalar_hex> --message <message_hex>
    To transfer all SOL to another address: 
    ./ucw-eddsa-signing transfer --key <scalar_hex> --to <address> --all
  3. The tool outputs the transaction hash once submitted.
Your Cobo wallet continues to work normally after export — both wallets control the same funds, so transactions in one affect the balance in both.
