If you died tomorrow, could your family access your crypto?

Most people can't answer that. They have Bitcoin on a Ledger, Ethereum on Coinbase, an NFT on OpenSea, and some staked SOL on a phone wallet. Nobody else knows what or where any of it is.

A will doesn't fix this. If your heirs don't have the seed phrase, the assets are gone — but the CRA still wants the capital gains tax.

~90% of crypto holders worry about this. Under 25% have a documented plan.

Run your numbers

The asymmetry is what most people don't realize until it's too late.

owed by your estate regardless

Illustrative — not tax advice. Canadian deemed-disposition rules treat crypto as sold at fair market value on the day of death. Thumbnail assumes ~20% effective tax (50% capital-gains inclusion × Ontario marginal rate, typical low cost basis). A CPA does the real math.

How it works

Built so a non-crypto-native family member can actually follow it.

  1. 01

    Inventory every asset

    A guided wizard walks through every place you hold crypto — exchanges (Newton, Bitbuy, Coinbase), hardware wallets (Ledger, Trezor), software wallets, NFTs, ENS domains, staking positions. The point is completeness: you can't pass on what you forgot you owned.

  2. 02

    Record where access lives

    For each asset, document where the keys, PINs, and recovery codes physically are — "Ledger in safe deposit box at TD, PIN sealed with my lawyer." Encrypted in your browser before it leaves your device. We never see the contents.

  3. 03

    Generate the executor playbook

    A printable PDF your family hands to a lawyer. Each exchange's death-of-account procedure baked in. A Canadian deemed-disposition tax worksheet. Letter templates to your executor and heir. Written for a 65-year-old who's scared of crypto.

  4. 04

    Keep it current

    Annual review reminders. Heads-up when a Canadian exchange changes its inheritance policy. One-click "still works" or "let me update."

Built for Canada

Deemed-disposition tax. Provincial succession law. Built around how Canadian exchanges actually handle death-of-account.

Zero-knowledge by design

Everything sensitive is encrypted in your browser before it touches our servers. We can't read your data. Not even if we wanted to.

Works with what you have

Coinbase, Ledger, MetaMask, Newton, Bitbuy, OpenSea, ENS — wherever your assets actually live. No need to move anything.

A note from the founder

I'm Juan, a software engineer in London, Ontario. I've been thinking about this problem because crypto holders are aging into the demographic that needs estate planning, and the existing tools either sell custody (Casa, Unchained) or don't handle crypto at all (Willful, Epilogue).
