SABLE Protocol Non-custodial private banking

The private bank,
on Robinhood Chain.

Hold, pay, save and move your assets from a vault only your wallet can open. Dollars, ether and tokenized stocks. No accounts, no custody, no one standing in between.

The bank

Four instruments.

Real, working banking tools inside the dashboard. Every action builds a Robinhood Chain transaction that only your wallet, or your vault key, can sign.

Private Vault

A second address rebuilt from your signature. It never appears in your wallet app and only you can re-derive its key.

How it works

Three quiet steps.

From a wallet you already own to a private vault you alone can open.

Connect

Bring the wallet you already use.

MetaMask, Rabby, Coinbase Wallet or any EVM wallet. SABLE adds Robinhood Chain for you. No sign-up, no email, no password database waiting to leak.

Open the bank

Unseal

Derive your private vault.

Sign one message. Your vault key is rebuilt from that signature inside the tab, every time, and is never stored or sent anywhere.

Unseal vault

Operate

Pay, save and move.

Deposit to the vault, pay with private notes, save into T-bills and index ETFs, and send ETH, USDG or stocks, each confirmed by your own signature.

Architecture

Discretion, by design.

There is no SABLE server that holds your money or your keys. The bank is a set of instruments that run in your browser and speak directly to Robinhood Chain.

Same wallet, same vault. Always.

Non-custodial at every step

Funds only ever move between addresses you control. SABLE cannot move, freeze or recover them. You can export the vault key into any wallet at any time.

Your address is the account

No passwords, no KYC servers, no profile. Disconnect and the session ends. Revoke at any time from your wallet.

Minimal metadata

No analytics, no trackers, no cookies. Payment notes and activity live on your device unless you choose to publish a note on-chain.

Every state visible

Input, review, signature, propagation, finality. Each transaction is gas-simulated on Robinhood Chain before you sign, and ends with a verifiable hash.

Plain words on risk. Robinhood Chain transactions are public: a vault adds separation, not anonymity, and deposits are visible on-chain. If you lose access to your wallet, you lose access to the vault it derives. Tokenized stocks and swaps rely on third-party contracts and oracles. Nothing here is unhackable, and we will never claim it is.
