While you are alive, the service provider is your most reliable helper. But if you pass away and the provider goes down first, how much of your recovery plan is left?

This is not a hypothetical scenario. In July 2026, Loopring DEX announced it would permanently stop trading services, the relayer went offline, and user assets needed to be returned to L1 wallets in batches by the official team. In the same month, EMURGO shut down SecondFi, and the team shifted to "building an on-chain auditable recovery system." Earlier, after BlockFi went bankrupt, the platform closed, and users were forced to withdraw through Coinbase. Those who did not act in time had their assets converted into cash.
The common point in these cases: after a service stops, users still have a way out, but it is not because "the service provider keeps helping." It is because "the assets themselves remain on-chain."
So if you rely on a platform that provides "crypto wills" or "inheritance custody" services, and it suddenly shuts down, can your preset recovery plan still be executed?
The answer depends on which type below your plan belongs to.
Case A: Your plan depends entirely on a centralized service provider (exchange inheritance feature or will platform)
For example, you set an emergency contact on Binance. The path is: homepage → personal information → account security → emergency contact. Or you use a decentralized dead man's switch like Sarcophagus, storing an encrypted private key file on Arweave and naming a recipient.
[What to do]: Evaluate the real impact of "platform shutdown" on "your heir getting the assets."
[How to do it]: Judge in two layers:
| Dependency layer | Example | Impact after platform shutdown |
|---|---|---|
| Trigger mechanism depends on platform | Binance's "notify emergency contact after long-term account inactivity" feature | The notification may not be sent, but assets remain in your Binance account. Heirs can apply to withdraw through the normal inheritance process (death certificate + probate), provided the platform is still operating. If the platform itself collapses (like BlockFi), assets enter bankruptcy proceedings and heirs can only participate in distribution. |
| Private key/file storage depends on platform | Sarcophagus encrypted private key file stored on Arweave | Arweave is an independent storage layer. Sarcophagus shutting down does not affect file readability. As long as heirs know where to look and what tool to use to decrypt it, assets can be recovered. |
[Completion standard]: You can clearly answer: "If this company closes tomorrow, what will my heirs get, through what channel, and how long will it take to receive the money?"
If the path is assets on a CEX: the core risk is the platform collapsing, not the feature stopping. An alternative is to move large amounts from exchanges to self-custody wallets in advance, keeping only daily-use amounts on the exchange.
If the path is files stored on-chain: the core risk is "heirs do not know where the file is." An alternative is to write in the will inventory: "The encrypted file is stored at the corresponding Arweave address, and the decryption key is in the designated location."
Case B: Your plan is based on on-chain smart contracts (multi-sig / time lock / decentralized will protocol)
The advantage of this type is: smart contracts are deployed on a public chain. As long as the chain still exists, the contract logic still exists.
[What to do]: Confirm whether your inheritance logic depends on "external triggers" rather than purely on-chain execution.
[How to do it]: Distinguish two subtypes:
| Plan type | Example | Shutdown impact | Can you self-rescue? |
|---|---|---|---|
| On-chain self-executing contract | Multi-sig wallet (Safe), time-lock contract | The frontend interface (such as Safe Web App) shuts down, but the contract itself is on-chain. You can directly call the contract function (execTransaction) through a block explorer to complete signing and transfer. | ✅ Yes, requires understanding ABI and direct contract calls |
| Depends on off-chain service triggers | Relies on Chainlink Automation or Keepers network to execute "auto transfer after expiry" | If the service provider stops running these Keepers, the smart contract's automatic trigger function may not be called, and assets will not automatically transfer. But the contract's "manual trigger" function is still available, and heirs can initiate the call themselves. | ⚠️ Partially usable, requires heirs who can operate manually |
[Completion standard]: You know which type your plan belongs to, and if it is the second type, you have confirmed the backup manual trigger path (which function, what parameters are needed, and who pays the gas fee).
Common failure reason: treating the "interface" as the "service"
Many users cannot tell the difference between "a platform's frontend interface" and "the on-chain contract itself." They think if the website cannot be opened, the assets are gone—that is a misunderstanding.
Wrong belief: "I have to wait for Safe to restore its website before I can operate the multi-sig."
Correct belief: Safe is a smart contract deployed on the Ethereum mainnet. Even if Safe the company goes bankrupt, your multi-sig wallet can still transfer assets by directly calling the execTransaction function through Etherscan. What you need is someone who understands this process, not to wait for the official website to recover.
This is why the core of a crypto inheritance plan cannot be "a company's promise", but must be "verifiable and executable logic on the blockchain." Companies can fail and frontends can close, but as long as the chain exists, the contract exists.
Risk warning: if the contract itself has admin privileges
Some inheritance protocols keep "upgradeable" or "admin pause" permissions in the contract. If the development team did not transfer or renounce ownership before shutting down, the contract may be permanently frozen, or there may be a backdoor control risk.
How to check: View the contract code in a block explorer (such as Etherscan) and search for keywords like onlyOwner, pause, and upgrade. If these permissions exist and have not been transferred to a DAO or destroyed, your asset recovery ability still ultimately depends on the development team, not full decentralization—so it is essentially no different from Case A.

How to verify after completing the operation
After the above evaluation, do a "worst-case drill":
Assume the protocol frontend you use has closed: Directly through a block explorer, manually check the current state of your deployed inheritance contract (such as remaining time-lock time, multi-sig signature status, beneficiary address).
Simulate "active triggering" rather than "waiting for automatic triggering": If it is a plan that requires Keepers to call periodically, try manually calling the inheritance contract's claim or execute function (on a testnet or with a very small amount) to confirm this path works.
Write an "offline operation manual": Put the manual operation steps above (including contract address, function name, parameter format, gas estimate) into a paper document and store it separately from your mnemonic phrase. If all Web3 frontends disappear, this manual is your heir's lifeline.
