Three jurisdictions.One vault. Zero custody.
You live in Dubai. Your parents are in Lisbon. Your kids are in New York. The wires are slow, the fees are punitive, and the regulators of three countries each want a say. The vault doesn't care about borders.
The expat problem
Cross-border families are now the rule, not the exception. Tech, energy, finance, sport. The people earning meaningfully in crypto often have parents in one country, partners in another, children in a third, and assets on chains that don't recognize any of those borders.
Traditional finance hates this configuration. SWIFT messages take days. Wires bounce on local holidays. Remittance services charge three to six percent, sometimes more, often quietly. And the inheritance question becomes a labyrinth: which country's probate? Which country's tax? Which country's bank?
What the vault changes
Your wealth lives on chains that don't ask which passport you hold. Your transfers and inheritance run on rules you wrote, not on the calendars of three financial systems. We aren't proposing you opt out of the legal world. We're proposing that the mechanics of moving and passing on assets stop being a nightmare.
One vault. Standing orders to anyone, on any chain. Inheritance to anyone, on any chain. Recovery from anywhere. The contract runs the same way whether you initiate it from a phone in Singapore or a desktop in São Paulo.
"I've moved three times in five years. The vault came with me. Nothing was signed away, nothing was re-paperworked. My parents still get their monthly support. My kids still know what's coming."
Lisbon → Dubai → Singapore
Patterns we see
The remittance replacement
You set a monthly standing order to a parent's wallet on whichever chain they prefer. They convert to local currency on their own schedule. No three-percent fee. No bounced wires. No embarrassing PayPal notification arriving at dinner.
The split-jurisdiction inheritance
Children in different countries each inherit a share of your crypto without dragging probate from one country into another. Your shares are written in the contract. Each child claims into a wallet they hold in their own country. The vault doesn't make tax disappear. But it does make the mechanics one less thing to worry about.
The "I might move again" plan
You're not sure where you'll be in five years. The vault doesn't care. There's no "registered office," no jurisdiction-locked contract, no service that can be revoked because you changed your tax residence. The vault is yours wherever you are.
What it doesn't solve
HeirVault doesn't tell you what the right tax answer is for your jurisdiction or your heirs'. It doesn't make a will redundant. It doesn't replace a competent international estate lawyer when you have one. We tend to suggest you have one, and the lawyers we work with regularly tell us the vault has made their job easier, not harder.
The chains, in case you're wondering
EVM chains: Ethereum, Base, Arbitrum, Polygon, BSC, Avalanche, Hyperliquid. Plus Bitcoin (Taproot multisig), Tron, and Solana. All in one account, one set of rules, one heartbeat.
