The Ethereum wallet with a post-quantum core.
Blockle is a free, non-custodial wallet for Ethereum (ETH) — the leading smart-contract network. Hold ETH and any ERC-20 token, connect to dApps over WalletConnect, and swap or bridge into BLOCK. All from one seed, protected by a post-quantum (ML-DSA) master key.
Why hold ETH in Blockle
Your Ethereum private keys never leave your device. Not your keys on a server — your keys on your machine.
Every account, Ethereum included, is derived from a NIST ML-DSA-44 (FIPS-204) key, so your master secret and backup are quantum-resistant.
Hold ETH next to Bitcoin, Ethereum, Solana and more — no separate app per coin.
On-ramp ETH through MoonPay's regulated flow, delivered straight to your own address.
Trade ETH for other assets and move value across chains, non-custodially.
Use the same Ethereum wallet in your browser, on Windows/macOS/Linux, or on Android.
One wallet for every chain
Blockle holds all of these from a single post-quantum seed — tap any to learn more:
Ethereum wallet FAQ
Is Blockle a non-custodial Ethereum wallet?
Yes — your Ethereum keys are generated and sealed on your device and never sent to any server.
Can I buy Ethereum with a card?
Yes, where available: Blockle opens MoonPay's regulated on-ramp and the ETH is delivered to your own wallet address.
Is my Ethereum wallet quantum-safe?
Your Blockle master key and backup are post-quantum (ML-DSA-44); the ETH assets inherit Ethereum's own cryptography until that chain adopts post-quantum signatures.
