A self-custody workspace for large crypto holders. Protect assets behind a multi-signature vault, swap wallet-to-wallet across chains, and add social recovery — with no account, no identity data, and keys that never leave your device.
Security primitives that remove single points of failure — without a custodian holding your assets.
Configure a vault with 2 to 9 co-signers and a signing threshold you choose. No single key can move funds on its own, so one compromised device does not cost you the vault.
Swap wallet-to-wallet using hashed time-locked contracts. The trade either completes in full or your assets are returned automatically — no bridge, no intermediary custody.
There is nothing to sign up for. The workspace runs client-side and never asks for identity documents or personal data — you keep full control of your information.
Route larger trades without dumping them into a thin order book. The workspace is designed for high-value, low-slippage movement between wallets you control.
Designate trusted guardians who can help you recover access — without ever gaining the ability to move your funds. A time-lock lets you cancel a malicious request.
Support for Lightning and fast L2 networks keeps transfer costs and confirmation times down, so large moves settle without waiting on congested mainnet blocks.
Four steps, entirely under your control.
Launch the app in your browser — nothing to install, no account to create. Connect a wallet you already control.
Set the signing threshold and add co-signers or hardware keys. Define a daily auto-approve limit for smaller spends.
Move assets between supported networks wallet-to-wallet using atomic swaps — no bridge and no custodian in the middle.
Optionally appoint guardians and set an inheritance plan so access survives a lost key, without handing over control.
The chains supported in this workspace build.
No custodian, no accounts, no stored identity. Here is exactly what that means.
Private keys are used locally and are never transmitted to Whale Nest. There is no server-side signing and no key escrow.
Atomic swaps lock funds in on-chain contracts that either complete the exchange or refund you. Whale Nest never takes custody of your assets to perform a swap.
Guardians can help you regain access, but they cannot move funds. A time-lock window means a fraudulent recovery request can be cancelled from any active device.
The app you can launch here is a functional interface demonstration. Live vault deployment and swaps require deployed contracts, a connected wallet and gas.
Launch the self-custody vault and swap interface. No account, no KYC, no install.
