Testnet preview

On-chain inheritance,
running on testnets.

Deploy your own vault contract, approve the tokens and NFTs you want covered, and assign them to beneficiaries by percentage. The contracts are real and so is the flow — they currently run on Sepolia and Polygon Amoy, not on mainnet.

This does not protect your mainnet holdings yet

The Crypto and NFT Will is wired to Ethereum's Sepolia testnet and Polygon's Amoy testnet. Test networks use valueless tokens, which makes them the right place to prove out a contract that will one day hold real assets — and the wrong place to assume your actual portfolio is covered.

  • Assets on Ethereum, Polygon, or any other mainnet are not covered by a vault you deploy today
  • Test tokens have no monetary value, so nothing you assign here is a real transfer
  • Bitcoin is not supported — the vault works with EVM token standards
  • Use it to understand the mechanism and give us feedback, not as live estate protection

If you want crypto represented in your estate plan right now, record the wallet addresses under Wallet Monitoring and describe your holdings in the Crypto Exchange Will, which produces a document your executor can act on.

The Problem

Billions lost to lost keys.

20%

Of all Bitcoin is estimated lost

Widely cited analyses of dormant supply put a fifth of Bitcoin beyond reach, much of it from keys that died with their owner.

0

Recourse without the keys

No support line can restore a self-custodied wallet. If nobody inherits the means of access, the asset simply stops moving.

Test networks supported today

Sepolia and Polygon Amoy. Mainnet support is not enabled, so treat this as a preview of the mechanism rather than live cover.

How it is built

Real contracts,
on test networks.

You deploy your own vault

A vault contract is deployed from your wallet through a factory. You approve which tokens it may move, and you keep your private keys throughout.

Assets are discovered, not typed in

Your holdings on the supported test networks are read through Alchemy, so you assign from the assets the wallet actually contains.

Assignments are read back from chain

Existing assignments are reconstructed by decoding on-chain calldata and cross-referencing transfer logs, so what you see reflects contract state rather than a local cache.

What happens on death

Distribution is not automatic and there is no inactivity timer. The vault holds the assignments you set; releasing them is part of the human-reviewed Claim Property process, where your executor uploads a death certificate and supporting documents for review.

Questions about the Crypto & NFT Will

Starting with the one that matters most: what it does and does not cover today.

No. It runs on Ethereum's Sepolia testnet and Polygon's Amoy testnet, which use valueless test tokens. A vault you deploy today does not cover assets held on any mainnet. We would rather you know that plainly than discover it later.
Proving out the mechanism. The contracts, the asset discovery, and the beneficiary assignments are all genuinely implemented — they are simply pointed at test networks. You can deploy a vault, approve a test asset, split it between beneficiaries, and see precisely how on-chain inheritance would work.
Two things help today. Register your wallet addresses under Wallet Monitoring so the holdings are recorded as part of your estate inventory. Then complete the Crypto Exchange Will, which produces a document describing your holdings and intentions that your executor can act on through the normal estate process.
Sepolia and Polygon Amoy, both EVM test networks. The vault works with ERC-20 fungible tokens, ERC-721 NFTs, and ERC-1155 multi-tokens. Bitcoin is not supported, since it does not use these token standards.
No. You connect your own wallet and sign every transaction yourself. The vault contract is deployed from your address, and approvals are granted by you. Legacy Suite never takes possession of a key or a seed phrase.
Asset discovery reads your holdings on the supported test networks through Alchemy, so you assign from what the wallet actually contains rather than typing in contract addresses by hand.
By percentage. You assign each approved asset across the beneficiaries you choose, so one token can be divided between several people and an individual NFT can be directed to a single person.
Yes. Existing assignments are reconstructed by decoding the on-chain calldata and cross-referencing transfer logs, so what the interface shows is derived from contract state rather than from a local record that could drift out of sync.
No, and there is no inactivity timer or dead man's switch. The vault records your assignments. Releasing anything runs through Claim Property, where your executor uploads a death certificate and supporting documents and a person reviews them.
MetaMask and WalletConnect. WalletConnect covers a wide range of mobile and desktop wallets, so most wallets that support the protocol will work.
It is not enabled today, and we are not going to put a date on it here. Moving contracts that hold real value onto mainnet deserves audit work and caution rather than a marketing promise. If mainnet support matters to you, tell us — it helps us prioritise.
On a test network you pay in test tokens, which are obtained free from public faucets and have no monetary value. There is no real transaction cost while the feature runs on testnets.

Deploy a vault, approve a test asset, and split it between beneficiaries. It costs nothing but test tokens, and it shows you exactly how the mechanism works.
