Full self-custody
Your keys, your crypto. No intermediary.
Own Your Assets.
In Self-Custody.
Self-custody means you hold the keys. Not Deblock, not a custodian,
not a third party. It's the most important thing about your wallet, and the hardest to get right.
Custodial vs. self-custodial,
the difference that matters
Most crypto apps are custodial. They hold your assets for you, like a bank vault you can't open yourself. Self-custody flips that: you hold the key, and nobody else has a copy.
Custodial (most apps)
e.g Revolut, Binance, Coinbase, TradeRepublic…
- The platform holds your crypto
- They can freeze your account
- If they get hacked, you lose funds
- If they go bankrupt, you're a creditor
- You need their permission to withdraw
Self-custodial (Deblock)
e.g Deblock, Ledger, Metamask…
- You hold your crypto in your own wallet
- Nobody can freeze your assets
- Deblock gets hacked? Your funds are safe
- Deblock disappears? Your wallet still works
- Withdraw anything, anytime, no approval
The promise
Keys always available
Export them from your settings anytime.
No limits
Deposit and withdraw with no cap.
Deblock-proof
Your assets survive even if we don't.
"But what if I lose my phone?"
The number one fear with self-custody. Deblock solves it with a split-key recovery system, designed so that only you can ever reconstruct your wallet, but you can always do it.
How it works?
When you sign up, your phone creates two things: your seed phrase (the master key to your wallet) and a separate encryption key. Your seed phrase gets encrypted into a recovery package. The encryption key stays with you via email, your cloud account, and a trusted escrow.
Deblock only ever sees the encrypted package. Without your encryption key, it's useless gibberish. And the encryption key on its own doesn't unlock anything either. You need both halves and only you have both.
Lose your phone? Deblock sends you the encrypted package, you decrypt it with your encryption key, and your wallet is back. No support ticket, no 30-day wait, no "we'll look into it".
Self-custody without the headaches
Owning your keys is the right model. But traditionally, it comes with real pain points. Deblock fixes the two that matter most.
Gas fees
ProblemTo move any token on-chain, you need the chain's native coin (ETH, SOL, etc.) to pay the transaction fee. It's common to own tokens but have no gas to move them, you're stuck.
With Deblock
SolutionWhen Deblock detects you can't afford the gas, it automatically airdrops just enough native token to complete the transaction. You don't even notice it happened.
Slow transactions
ProblemTransactions on Layer 1 chains like Bitcoin or Ethereum can take minutes, sometimes longer, with fees that spike under load.
With Deblock
SolutionDeblock supports Layer 2 networks: Lightning Network, Base, Arbitrum, and more. Where transactions confirm in seconds, not minutes.
Frequently asked questions
What happens if I lose my phone?
Re-install Deblock on a new device, log in, and the split-key recovery flow puts your wallet back. No support ticket, no waiting.
What if Deblock disappears?
Your wallet keeps working. Export your seed phrase from settings at any time and import it into any compatible wallet.
Do I really not pay gas fees?
When the app detects you're short on gas, it auto-airdrops just enough native token to complete the transaction. You only ever see the action, not the gas plumbing.
Which networks are supported?
Bitcoin, Ethereum, Solana, Ripple, Cardano, Hypercore and major Layer 2 networks including Lightning, Base and Arbitrum. More are added regularly.
