Why multisig needs to be easier
Self-custody only works if someone you trust can help.
Multisig can provide a way to share control of a Bitcoin wallet, but setting it up and using it can be difficult. Wallet formats, hardware devices, and instructions do not always fit together neatly. That complexity can be especially hard on a spouse, trustee, lawyer, accountant, or family member who may need to help when the wallet owner is unavailable.
Bitcoin Easy Signer is designed to make spending from an existing multisig wallet clearer for people who do not work with Bitcoin every day. It uses one public wallet-definition file and guides a helper through wallet checks, payment review, and hardware approvals—without asking the app user to enter seed words or private keys.
Review the payment
Check the destination, amount, network, fee, and any change before asking a hardware device to approve.
Approve on the devices
Connect compatible hardware keys, confirm the payment on each device, then review the finished transaction in the app.
A first look
See the app.
The app opens on live Bitcoin. Mainnet is marked in orange; practice networks appear only after a deliberate step into Developer Mode.
Screen 1 of 3. Sanitized interface illustrations based on version 0.6.2. No real wallet or payment data is shown.
A test bench, not the front door
Practice networks live behind developer mode.
The app opens on Bitcoin mainnet, the live network. A spouse, trustee, lawyer, or accountant using the app for recovery does not need practice networks. The opening screen keeps those choices out of the way; the orange frame, network badge, and warning name live Bitcoin clearly.
The optional Enter Developer Mode button is for people who already have a practice wallet and practice coins. It asks for confirmation, then offers Mutinynet or Testnet4. The app provides neither practice wallets nor coins. This is a test bench, not the purpose of the app. Its selection lasts only for the session, and the app reopens on Bitcoin mainnet. A practice transaction does not prove how a given device will handle change on a later live payment. If you do not know why you would use Developer Mode, do not use it.
For the person helping
A step-by-step guide for recovery.
The manual explains what to prepare, what each screen means, how hardware approvals work, and when to stop. It is written for a spouse, trustee, lawyer, accountant, or family member.

Bitcoin Easy Signer is free to use and maintained by Bitseeker LLC for the Bitcoin community. It does not create wallets or keys. It helps someone spend from an existing wallet using its BSMS definition and compatible hardware signers. It is designed to make the process more approachable for a loved one, trustee, lawyer, accountant, or other helper.
Up to three physical keys. The wallet file defines the threshold. Supported hardware depends on the app’s bundled HWI library; not every device is supported.
Hardware signing. Signing happens on the hardware wallets; the app never asks for seed words or private keys.
Practice networks. Testnet4 and Mutinynet are available for practice, reached through developer mode. Their coins are not real Bitcoin and do not transfer to mainnet.
Real Bitcoin can now be sent. Mainnet broadcast is available, behind a per-transaction confirmation on the final screen. No warranty is offered or implied. Verify every payment yourself, and never risk more than you can afford to lose.
