Legacy Protocol
Legacy Protocol · Maintained by LegacyApp

The open standard for passing on what matters.

When someone dies, their family is often left searching for accounts, policies, property, and instructions no one wrote down. Legacy Protocol gives any service that holds inheritable information a simple, open way to pass it on. The customer chooses where it goes.

The gap

The hard part is finding it.

Most people hold dozens of accounts, a few policies, a mortgage, maybe a crypto wallet, and a short list of people who should be called. That information sits across different institutions, apps, and drawers. When the moment comes, families spend months putting it back together, and some of it is never found.

There has never been a shared way to pass it on. Legacy Protocol is that shared way.

The vision

One button, everywhere it matters.

Every place that holds something valuable should be able to hand it forward. A bank that opens an account, an insurer that writes a policy, a crypto exchange that lists a wallet, a notary that records a will, a registry that holds a property title: each one can let the customer add a record to their digital legacy with a single click.

The record travels in an open format that any compatible app can read. The customer decides who sees it and when, and which service holds it. The result is a quiet promise kept: the people you leave behind will know what you wanted them to know.

Three steps

How it works

01

A partner adds an "Add to my legacy" button.

A bank, insurer, exchange, or app places it wherever a customer creates something worth passing on.

02

The customer authorizes the export.

One click. They choose what to share and with whom.

03

The record goes where the customer wants.

They can download it as a file, or send it to any inheritance service they trust. Any compatible app can read the format.

For adopters

What you gain by adopting it

A service customers remember.

Helping a family at the hardest moment builds trust that products rarely buy.

Almost nothing to carry.

The format is open and free to implement. No license fee, no exclusivity, no dependence on a single vendor.

Less strain on your own process.

Clear records make the work after a customer's death shorter for your teams and gentler for the family.

A seat at the table early.

First partners shape how the format works for their industry before it sets.

The format

What a record holds

Legacy Protocol is kept simple on purpose. Seven record types cover most of what a family needs.

Account01

A financial or digital account: a bank, broker, exchange, retirement plan, email, or social profile.

Asset02

Something of value that isn't an account: a property, a vehicle, shares in a business, valuables.

Liability03

A loan or a mortgage.

Insurance04

A policy and how to claim it.

Document05

An important document and where to find it: a passport, a will, medical records.

Contact06

An adviser, a broker, an executor.

Instruction07

Where the safe is, what to do first.

Records share a common category structure, so a "retirement account" or a "life insurance policy" means the same thing across apps. Customers can move between services without losing meaning.

Privacy and security

Built to stay private.

A record says that something exists and how to reach it. The secret itself stays where it belongs. For a crypto account, that can be as little as "an account exists on Kraken, the login is kept here." The private keys never travel.

Records are private and encrypted on the customer's side, so the systems that move the data never have to see its contents.

Stewardship

Open, and openly led.

LegacyApp created Legacy Protocol and maintains it. We say so plainly, because an open standard with a clear steward is easier to trust than one with none.

Work in progress

Still open for discussion.

The first version is small, and some of the most useful decisions are still open. Should a record carry an expiry date? A review reminder? How should we describe ownership: sole, joint, beneficiary, power of attorney? How much detail is enough for each industry? These are exactly the questions we want partners in the room for.
