STEP 01
Seal your will
Upload documents, keys and messages to IPFS, name beneficiaries with their allocation splits, and set your inactivity window — all on-chain.
- +Encrypted files on IPFS
- +Weighted beneficiary splits
- +Inactivity timer you choose

Silence is the trigger.
Seal your documents, keys and final messages on IPFS. Name your heirs, appoint custodians. Go quiet for long enough, and the program hands over exactly what you sealed — to exactly who you named.

How it works
Three steps. One signature each.
Blop replaces lawyers, paperwork and goodwill with a program that releases exactly what you sealed, to exactly who you named, exactly when your custodians confirm.
STEP 02
Appoint custodians
Name trusted custodians and choose how many must agree before anything unlocks. They can only confirm your passing — never read or move your files.
- +M-of-N custodian quorum
- +On-chain death confirmation
- +Add or remove anytime
STEP 03
Heirs inherit
Once you have gone inactive and the quorum confirms, the will turns claimable. Each beneficiary signs to unlock the payload — no executor, no intermediary.
- +Contract-enforced release
- +Per-beneficiary claim
- +Access to sealed documents
Interactive demo
Walk through a full will lifecycle.
Connect a simulated wallet, seal a will, and check in to stay active. Or skip the wait — trip the switch and watch the custodian quorum confirm, then your beneficiary unlock the sealed documents.

Built for keeps
Everything a will should be — and nothing it shouldn't.
Six guarantees, each one enforced by the program rather than promised by us.
01
On-chain + IPFS
Wills, beneficiaries and custodians live in one Solidity contract; your files live on IPFS. Only the content hash is stored on-chain.
STORAGE02
Custodian quorum
Appoint trusted custodians and require M-of-N to confirm your passing. No single party — including us — can trigger a release.
QUORUM03
Inactivity dead-man's switch
Set the window that arms your will. Custodians can only confirm once you have gone quiet; staying active keeps everything sealed.
TIMER04
Weighted beneficiaries
Name multiple heirs, each with an allocation in basis points. Add, remove or reweight them anytime while the will is active.
SPLITS05
Transparent & auditable
Every will update, custodian confirmation and claim is a public transaction. Anyone — including your heirs — can verify the state.
AUDIT06
L2-fast and cheap
Sealing, confirming and claiming each cost a fraction of a cent on an Ethereum L2. You pay gas only for the transactions you send.
COSTSecurity
Trustless, not trust-me.
Blop executes a contract you read, signed, and can verify on-chain. Your files are encrypted before they ever reach IPFS. No backdoors, no admin keys, no recovery hotline. That is the point.

Ok(())
}01
Non-custodial by design
Your files, your keys. The contract never holds your data — only IPFS content hashes — and only the rules you signed can open it.
02
Custodian-gated release
The will turns claimable only after you go inactive and an M-of-N quorum confirms. No off-chain authority can override it.
03
Open & auditable logic
Source verified on Blockscout. Two independent audits in progress.
04
Owner stays in control
While the will is active you can re-seal documents, reweight heirs, swap custodians, or revoke the whole thing.
Use cases
Built for anyone who can't afford to disappear.
Four patterns we see most often. The protocol is general — your rules can be too.
PersonalEncrypted on IPFS
Key & seed-phrase escrow
Seal encrypted recovery info on IPFS so heirs can reach your wallets and accounts — but only after custodians confirm you are gone.
DocumentsAny file type
Estate instructions
Wills, deeds, insurance policies and asset directories, hashed on-chain and released to the people you named.
MessagesPer-heir allocation
Final words
Letters, photos and video for loved ones, delivered exactly when your custodians confirm — not a moment before.
BusinessM-of-N custodians
Succession & access
Hand off credentials, runbooks and signing instructions so a company keeps running if a key person goes dark.
FAQ
The questions everyone asks first.
Only what you deliberately escrow. The contract holds no ETH at all, and no token unless you call Escrow on it — those ERC-20 deposits it does custody, and releases them to your heirs in the splits you set. Everything else it merely records: the content hashes (IPFS CIDs) of the files you seal, your beneficiaries and their allocations, and your custodians.
Two gates. First, your inactivity window has to elapse — staying active keeps everything sealed. Then your custodians sign on-chain death confirmations; once the M-of-N quorum you set is reached, the will becomes Claimable and each beneficiary can claim.
Custodians are wallets you trust to confirm your passing. Their only power is to approve a death confirmation — they can't read your files, change beneficiaries, or move anything. You choose how many must agree (the min_approvals quorum) and can add or remove them anytime the will is active.
Yes. While the will is Active, you can add, remove, or reweight beneficiaries, add or remove media references, and swap custodians — each a single signed transaction. Once a quorum confirms death, the will freezes into its Claimable state.
Any file type — documents, keys, images, video — pinned to IPFS. Encrypt it client-side before uploading; the chain only ever sees the CID and a short media-type tag, never the contents.
Just gas. Robinhood Chain is an Ethereum L2, so each transaction — creating the will, adding an heir or custodian, sealing a document, claiming — costs a fraction of a cent. There is no rent or per-record deposit to recover, and the protocol itself takes no fee.
Final step
Secure your legacy in minutes.
Connect a wallet, seal your documents, name your heirs and custodians. Stay active and nothing moves — go silent and your will does exactly what you wrote.
