Your people receive your assets if something happens to you.

Name who gets what, then check in now and then. If you stop for the number of days you set, the people you named can claim it, for free.

Set up your plan

Free to use. You pay only the Ethereum network fee.

Before you start

You need a wallet app, on your phone or in your computer's browser. If you use Coinbase, Coinbase Wallet works; MetaMask and Rainbow do too. Two minutes to install.

How it works

  1. Name who gets what

    Up to ten people, each with a share. Their names stay on your device; only wallet addresses go on Ethereum. If someone has no wallet, the app can make one for them and print its key on a card you hand over.

  2. Set your check-in window

    Choose how many days of silence it takes before your plan can be claimed. Checking in is one action on your plan's page, confirmed in your wallet. Sending or receiving money elsewhere does not count on its own.

  3. They claim, for free

    If the window runs out, any one of the people you named can claim, and each receives their share. 10102 pays the network fee. A printed claim card lets them do it even if this website is gone.

A head start on the quantum era

Quantum computers are expected one day to break the signatures Ethereum wallets use today. No machine can do it now. The 10102 app shows whether your wallet's public key is already exposed, and lets you record the fingerprint of a secret only you hold in a public registry. The record carries a date on Ethereum. If today's signatures ever break, there is a record, made before that day, that ties the secret to your wallet.

Quantum-ready, not quantum-proof. The registry moves no money and stops no attacker today. It cannot block a transaction either. What it gives you is the dated record, which recovery tools built later can honour. Losing the backup sheet costs you only the head start; you can register a fresh secret at any time.

What you should know

  • Nothing moves until then. Your assets stay in your own wallet and you keep using them as usual. Your people receive their share of the tokens you included, as they stand on the day they claim.
  • You have to check in. If you go quiet for the whole window, the plan becomes claimable. Pick a window you can live with. Optional paid extras can send you reminders or renew the plan from your normal wallet activity.
  • A printed key is like cash. If the app made a wallet for one of your people, whoever holds that card holds the money once it is claimed. Give it to them the way you would give cash.
  • Fees. Setting up costs a network fee, and so does checking in unless you take the paid extra that covers it. Claiming costs your people nothing.
More to know
  • It works without us. 10102 never holds your assets. The plan lives in an audited contract on Ethereum and your people can claim from any Ethereum interface with the printed card.
  • The plan passes tokens. ETH itself cannot be named in it. The app swaps ETH into a token form, such as wrapped ETH, that can.
  • Keeping assets in a Safe? There is a variant that hands the whole Safe to your people as co-signers instead. The app offers it when you create the plan.
