If by “natively” you mean the blockchain/token protocol itself automatically handles inheritance after inactivity, no major token currently does this at the protocol level. The dead-man-switch logic generally lives in a smart contract or wallet layer.
That said, Ethereum (ETH) is probably the strongest ecosystem for what you want:
One important distinction: if you specifically want to hold a token whose ecosystem itself has inheritance built in, rather than use a third-party inheritance service, I'd not choose a token based on that feature alone. You're really looking for a smart-contract wallet/vault on a programmable chain, with the assets held inside it.
If you tell me whether you want BTC, ETH/stablecoins, or a multi-chain portfolio, I can identify the safest currently available dead-man-switch wallet options and compare their trust model, fees, and failure modes.

Strictly speaking, no major token ecosystem natively builds a traditional "dead man's switch" (DMS) directly into its base protocol layer.
This is by design: blockchains are deterministic state machines. They have no native concept of human mortality, time-of-death, or "checking in" to prove an operator is still alive. If a protocol automatically transferred funds due to pure network inactivity, it would be vulnerable to false positives (e.g., if you fall into a coma, travel off-grid, or lose your phone) with no way to reverse the transaction.
However, different ecosystems achieve trustless or semi-trustless "dead man's switch" functionality using different architectural primitives:
nLockTime, CSV - CheckSequenceVerify, and Miniscript).resetTimer() transactions from your address. If the timer hits zero without a ping, a beneficiary function is unlocked, allowing designated heirs to pull or redirect funds.If you'd like to narrow this down, tell me:
I can provide a step-by-step layout of how to configure it safely.

No major layer-1 blockchain ecosystem supports a true, automated "dead man's switch" natively at the protocol or default wallet level , because public blockchains are purely reactive systems. A blockchain cannot independently verify if a human user is alive or dead without an external trigger (an oracle or time-based inactivity transaction).
However, smart-contract-enabled ecosystems like Ethereum (ETH), Arbitrum , and other EVM chains come the closest. They allow developers to build programmatic dead man's switches via smart contracts that require a periodic "heartbeat" (a check-in transaction). If the owner fails to ping the contract within a pre-set timeframe (e.g., 180 days), a function triggers to transfer or unlock the funds for a designated beneficiary.
Ecosystems and Approaches for a Dead Man's Switch
OP_CHECKSEQUENCEVERIFY and Bitcoin Miniscript . This allows you to script a vault where your key can spend the funds normally today, but after a specific block-height or relative time lock passes without activity, an alternate key (your heir's) gains spending authority.If you'd like, let me know:

The short answer is: no major cryptocurrency or token has a protocol-native "dead man's switch" for inheritance. This functionality is almost always implemented at the wallet, smart contract, or application layer, not by the blockchain or token itself. A blockchain cannot determine whether you've died—it can only observe whether you've submitted transactions or signed messages.
If your goal is to minimize trust while maximizing automation, here's how the major ecosystems compare:
| Ecosystem | Native inheritance? | How it's typically done | Overall fit |
|---|---|---|---|
| Ethereum (ETH) | ❌ | Smart contract wallets, account abstraction, automated smart contracts | ⭐⭐⭐⭐⭐ Best |
| Bitcoin (BTC) | ❌ | Multisig + timelocks (CLTV), inheritance wallets | ⭐⭐⭐⭐ |
| Solana (SOL) | ❌ | Smart contracts + off-chain keepers | ⭐⭐⭐ |
| Polkadot (DOT) | ❌ | Social recovery primitives | ⭐⭐⭐ |
If you want an experience that feels "native," Ethereum's ecosystem is currently the strongest because it has:
This makes it possible to build a wallet that:
It's still not built into ETH itself—it's built on top of Ethereum's programmable infrastructure.
Many security professionals actually recommend Bitcoin multisig inheritance instead of a dead man's switch.
For example, a 2-of-3 multisig might involve:
No automatic transfer occurs, but there's much less risk of an erroneous trigger or software failure. Bitcoin's timelocks can also be incorporated into more advanced inheritance schemes.
There are projects specifically focused on crypto inheritance and dead man's switches, but they are applications or protocols, not the native feature of a blockchain. Examples include Ethereum-based smart contracts and specialized inheritance protocols built on top of existing chains.
If your priority is:
If your holdings will be substantial (e.g. six or seven figures), it's also worth considering combining an on-chain solution with traditional estate planning so that your heirs have both the legal authority and the technical means to recover the assets.

Several blockchain ecosystems and specialized wallet solutions support dead man's switch functionality for crypto inheritance. The most mature options revolve around Ethereum-based smart contract wallets, specialized protocols like Aegis, and newer non-custodial solutions integrated with hardware wallets.
Key Ecosystems and Protocols
How They Work
These systems typically function by monitoring a "Heartbeat Signal"—a scheduled, automatic, or manual check-in by the owner. If the owner fails to check in before the timer expires, the contract (or protocol) authorizes the transfer of assets to pre-designated beneficiaries.

The short answer is: no major blockchain or token has a protocol-native "dead man's switch" for inheritance. This functionality is almost always implemented at the wallet, smart contract, or application layer, not by the cryptocurrency itself. A blockchain can't determine whether you've died—it can only verify cryptographic actions (or the absence of them).
If your goal is to minimize trust while maximizing automation, here's how the major ecosystems compare:
| Ecosystem | Native inheritance? | Maturity for inheritance |
|---|---|---|
| Ethereum (ETH) | ❌ | ★★★★★ Best overall |
| Bitcoin (BTC) | ❌ | ★★★★☆ Excellent with multisig/timelocks |
| Solana (SOL) | ❌ | ★★★☆☆ Smart contracts can implement it |
| Polkadot (DOT) | ❌ | ★★★☆☆ Strong recovery primitives |
Ethereum's smart contract capabilities and account abstraction make it the most mature platform for inheritance solutions. You can build or use wallets that:
These features are enabled by smart contracts rather than ETH itself.
Bitcoin doesn't have automated dead-man-switch logic, but it has mature primitives:
These tend to be more conservative and easier to audit than complex smart contracts, though they're generally less automated.
Several projects implement inheritance on top of blockchains rather than inside them. Common approaches include:
These are application-layer protocols, not token features.
If your priority is fully trustless, easy for non-technical heirs, or avoiding any third-party service, I can narrow the recommendations further because those requirements lead to quite different designs.

The short answer is: no major cryptocurrency or token ecosystem supports a dead man's switch natively at the protocol level. A blockchain cannot determine whether you've died; it can only observe signed transactions or other on-chain activity. As a result, inheritance logic is almost always implemented in the wallet, smart contract, or application layer, not by the token itself.
If you're looking for the ecosystem with the strongest support, here's how they compare:
| Ecosystem | Native dead man's switch? | Practical support |
|---|---|---|
| Ethereum / EVM (ETH, Base, Arbitrum, Polygon, etc.) | ❌ | ⭐⭐⭐⭐⭐ Best choice due to smart contracts and account abstraction |
| Bitcoin | ❌ | ⭐⭐⭐ Timelocks and multisig can implement inheritance, but setup is more technical |
| Solana | ❌ | ⭐⭐⭐ Smart contracts can do it, but the ecosystem is less mature for inheritance |
| Polkadot | ❌ | ⭐⭐ Good recovery primitives, fewer production inheritance solutions |
The closest is Ethereum's smart-contract wallet ecosystem.
Instead of holding ETH in a standard externally owned account, you use a programmable smart wallet that can implement rules like:
Those capabilities are enabled by the wallet and smart contract, not by ETH itself.
Several projects already implement these ideas:
If inheritance planning is your primary goal, I'd choose:
This gives you the most mature tooling while remaining self-custodial.
If your priorities are maximum decentralization, simplicity for non-technical heirs, or holding mostly Bitcoin rather than ETH, the best solution differs, and I can recommend an architecture optimized for that specific use case.

The short answer is: no major cryptocurrency or token ecosystem supports a dead man's switch natively at the protocol level. A blockchain cannot determine whether you've died; it can only observe on-chain events such as signed transactions or missed "heartbeat" check-ins. As a result, inheritance is almost always implemented in the wallet, smart contract, or application layer, not by the token itself.
If your goal is the closest thing to a native experience, here's how the major ecosystems compare:
| Ecosystem | Native inheritance? | Best available approach |
|---|---|---|
| Ethereum / EVM | ❌ | Smart-contract wallets, account abstraction, programmable inheritance |
| Bitcoin | ❌ | Multisig + timelocks (CLTV, CSV), specialized wallets |
| Solana | ❌ | Smart contracts with inheritance dApps |
| Polkadot | ❌ | Social recovery building blocks rather than inheritance |
Ethereum has by far the richest infrastructure for inheritance because it supports programmable smart contracts. Common patterns include:
These are implemented by smart contracts and wallets rather than ETH itself.
If most of your assets are Bitcoin, many security experts favor multisig inheritance rather than a dead man's switch. Wallets such as Nunchuk implement inheritance schemes where an heir gains signing ability after a predefined period or legal process, avoiding automatic transfers while you're alive.
Ethereum is where you'll find the most mature options:
A fully automatic dead man's switch has trade-offs:
For large holdings, many experienced self-custody users prefer:
If your priority is maximum decentralization, ease of use for heirs, or minimal trust in third parties, I can recommend architectures tailored to that goal.
