Use ETH in a personal wallet, a cold-wallet setup, or a multi-party MultiSig approval flow, depending on how the assets are owned.

About Ethereum
What is Ethereum (ETH)?
Ethereum, live since 2015, is the leading smart-contract platform and introduced the ERC standards that power most of today's tokens and NFTs. It uses an account model and, since 2022, proof-of-stake consensus. In Ownbit, Ethereum MultiSig is an open-source on-chain contract you can independently verify, and a single wallet can hold ETH plus any ERC-20, ERC-721, or ERC-1155 asset with air-gapped cold-wallet signing.

What you can do with it
Ethereum in Ownbit
Self-custody by design
Your ETH mnemonic and keys are generated and encrypted on your own device — never uploaded for remote custody.
Cold-wallet workflow
Track ETH on a Watch Wallet and sign offline on an air-gapped phone; transactions move as QR codes.
On-chain MultiSig
an open-source on-chain multisig contract requires 2-of-3 or weighted approvals before any ETH moves.
How it works
How Ethereum works in Ownbit
On Ethereum, an Ownbit MultiSig is an open-source, on-chain smart contract that enforces M-of-N approval before any transaction executes. You keep your own keys, approve from separate devices, and can read or interact with the contract independently of Ownbit's servers.
Recovery and compatibility
Ethereum recovery & compatibility
For standard Ethereum wallets, recovery completes with your mnemonic or private key in any compatible wallet. For MultiSig, each participant keeps an independent key and can recover from the wallet's on-chain configuration without depending on Ownbit's servers.
FAQ
Ethereum wallet — frequently asked questions
Does Ownbit support Ethereum MultiSig?
Yes. Ownbit supports on-chain M-of-N MultiSig for Ethereum — an open-source on-chain multisig contract. You can set anything from a 2-of-2 personal wallet to weighted enterprise approvals, and the threshold is enforced on-chain rather than by a server.
Which Ethereum assets can I hold?
Ownbit manages ETH plus any ERC-20, ERC-721 or ERC-1155 token on Ethereum.
Is my Ethereum self-custodial in Ownbit?
Yes. Your ETH mnemonic and private keys are generated and stored encrypted on your own device. Ownbit never holds them and cannot move, freeze, or access your funds.
Can I use Ethereum as a cold wallet?
Yes. Pair a Watch Wallet on an online phone with an offline signing phone; unsigned and signed transactions move between them as QR codes, so your keys never touch the internet.
How do I recover my Ethereum if I lose my phone?
Restore your BIP39 mnemonic in Ownbit or a compatible wallet. For MultiSig, each participant recovers with their own key plus the wallet's public configuration — no Ownbit server required.
