// No lies

Honest
by design.

Every screen tells you exactly what's happening: which network, which token, and what it costs. No testnet theatre, no hidden custody, no later.

Three things we guarantee

Not features that ship someday. Properties of how the wallet is built, today, on mainnet.

[✓]Keys

Non-custodial by construction

Your keypair is generated and held on-device. There is no Blochisland account that can move your funds. Lose us, keep your blochs.

[✓]Mainnet

Real funds, real chain

What you see is what is on-chain. Confirmations land the moment the block does.

[✓]Fees

No surprise costs

The network fee is printed on every send. Around ~0.000005 SOL. That is it.

// On-device signing

Your keys,
on your device.

The send screen names the network, the token, and the exact fee before you sign. The signature is built and approved locally, then broadcast. Nothing about your secret leaves the device.

Touch ID and the macOS Keychain lock your wallet on this device. Your private key is the one backup that matters: write it on paper, keep it offline. Blochisland never sees it, so we can never reset it for you. That is the trade you wanted.

The key below is a demo. Yours is forged on-device the first time you open the app, and shown only once.

What Blochisland can not do

The shortest way to understand a wallet is to know what it is incapable of. These are not promises. They are constraints.

  • ×

    Never custody your funds

    Your keys live on your device. Blochisland has no server that can move, freeze, or lend them.

  • ×

    Never hide a fee

    The network fee is printed on the send screen before you sign. No spread, no markup, no surprise line item.

  • ×

    Never fake testnet as mainnet

    Every screen names the network. If it says mainnet, the funds are real and on-chain.

  • ×

    Never phone home with your keys

    Signing happens locally. Your private key is never transmitted, logged, or backed up to us.

  • Hold your
    own keys.

    Open Blochisland, unlock with Touch ID, back up your key, and the wallet is yours. We never held it in the first place.
