01 // The gap
Your family may inherit your assets.
That does not mean they can access them.
Crypto ownership is absolute. If no one knows your wallets exist, where your access information is stored, or what you intended to leave behind, the value you built can become permanently inaccessible.
A legal will can name an heir. It cannot safely give them the knowledge, context or technical path needed to access self-custodied digital assets.
2.3M–4MBTC
Estimated to be permanently lost
Estimates vary by methodology. Roughly 11–18% of Bitcoin's 21M supply is believed to be permanently inaccessible.
708M+
Global crypto owners
Crypto.com reported 708M global cryptocurrency owners in H1 2025; full-year estimates are around 741M.
18–32%
Of crypto investors have explicit inheritance arrangements
Research varies between having any instructions and formally including crypto in estate planning.
Sources + methodology available in the upcoming research library.
02 // A plan for what happens next
Prepare the plan.
Keep control.
Leave a clear path.
InheritChain is being designed to help crypto holders prepare a private digital legacy plan that non-technical beneficiaries can actually use.
01 / Prepare
Define what you want to leave
Connect your wallet, choose who should receive what, and add private documents, instructions or personal messages.
02 / Stay in control
Your assets remain yours
InheritChain is being designed to minimise custody and keep you in control of your assets.
03 / Guide the claim
Make the next step human
When the time comes, beneficiaries receive a clear, guided path to understand what was left to them and what to do next — without needing to understand blockchain.
03 // Trust is the product
Built for a moment
that should not feel technical.
Digital inheritance sits at the intersection of family, money, grief and technology. Every part of InheritChain is being designed to reduce uncertainty, preserve privacy and keep people in control.
Non-custodial by design
The goal is simple: you should not have to give up ownership of your assets to prepare for the future.
Private by default
Sensitive plan details, personal information and beneficiary rights should not become public simply because they need to be verified.
Human-first UX
The person receiving your legacy may be grieving, may not know what a wallet is, and should never need to guess what to do next.
Open to verification
The protocol is intended to be open source, independently reviewed before real-asset use, and transparent about its technical and legal limits.
04 // Building with the people it serves
This is not a product
to build in isolation.
InheritChain is currently in research and MVP design. We are speaking with crypto holders, potential beneficiaries and people who have experienced the difficulty of planning for digital assets.
Join the waitlist to follow the build, receive early access when testing begins, and help shape a legacy experience that works in real life — not only on paper.

05 // Founder note
Designed for
real people.
Rafaela Costa is a strategic UX/UI designer & product builder.
She has followed and used crypto since 2013, primarily as a long-term user. In 2025, she completed SheFi Cohort 14 and began turning her interest in digital ownership, privacy and human-centred technology into hands-on product work.
InheritChain is built around a simple belief: complex technology only matters when the people who need it can actually use it.
