This guide shows how to move a private key from Trust Wallet to MetaMask, and how to export or import a private key in MetaMask on both desktop and mobile. It sticks to the practical steps you actually need, plus explicit warnings where things go wrong. I’ve done this several times while consolidating accounts for daily DeFi use. Short version: export carefully, import carefully, then test with a tiny transfer.
You might export a private key for several reasons: migrate an account to a different app, recover an account that isn’t covered by a seed phrase, or split control across devices. Importing a private key into MetaMask gives you immediate signing access with the same address — no seed phrase derivation required.
But there’s a trade-off. Private keys are a single-string secret. If anyone else sees it, they control the funds. Hardware wallets avoid this risk by keeping keys offline; software wallets do not. Ask yourself: do you need the convenience of a hot wallet, or the security of cold storage?
And yes, copy-paste is dangerous. I’ve lost time and money copying keys to an exposed clipboard. Don’t be that person.

Note: menu labels change across app versions. The pattern below reflects the common flow — the app will ask for your PIN or biometric before revealing a private key.

If you don’t see an option to export a private key, the wallet may only allow seed phrase export. In that case, restore the seed phrase in the destination wallet instead or follow the migrate from Trust or Coinbase guide.
Note: imported accounts in MetaMask are not derived from your MetaMask seed phrase. If you reset MetaMask and only have the MetaMask seed, imported accounts will not be restored unless you also saved their private keys.
Important tip: the phrase private key string metamask mobile describes the raw hex string MetaMask mobile accepts. Avoid extra spaces or line breaks. If the app rejects the key, re-check for any accidental characters.
I once imported a private key without testing gas settings and paid double the gas because I was on the wrong network. Learn from my mistakes.
| Feature | MetaMask (extension & mobile) | Trust Wallet (mobile) | Hardware wallet (cold) |
|---|---|---|---|
| Can import a private key | Yes (Import Account) | Yes (export private key from app) | Generally no (keys stay on device) |
| Can export a private key | Yes (Account → Export Private Key) | Yes (requires PIN/biometric) | No (designed not to) |
| Mobile-friendly | Yes | Yes | Limited (requires companion app) |
| Best for daily DeFi use | Yes | Yes | Not ideal for quick mobile swaps (but most secure) |
| Recommended for long-term holding | Use with hardware for best safety | Use with hardware for best safety | Best (keeps private keys offline) |
This table focuses on private-key handling, not feature parity. For other comparisons see vs-trust-wallet and hardware-wallets.
Q: Is it safe to keep crypto in a hot wallet? A: Hot wallets are convenient for DeFi and daily swaps, but they expose keys to the device. For large balances use a hardware wallet. For general safety see security-best-practices.
Q: How do I revoke token approvals after importing an account? A: You can revoke approvals in the same way as any account. Use on-chain tools or see our guide on revoke approvals.
Q: What happens if I lose my phone after importing a private key? A: If the account is only stored as an imported private key and you didn't save that key elsewhere, you can't recover it. That’s why backing up either the seed phrase or the private key beforehand is critical—see backup-and-recovery-options.
Q: Should I import multiple private keys into MetaMask or restore a seed phrase? A: If accounts are all derived from one seed phrase, restoring the seed is cleaner. Importing many separate private keys becomes hard to manage and may not be restored by a single seed.
Exporting and importing private keys between Trust Wallet and MetaMask is a straightforward process, but the risk is high if you skip the safety steps. Do a test transfer. Keep backups. Prefer hardware wallets for large balances.
