still here?

the chain keeps everything. it gives it to no one.

Every address on Ethereum has one failure mode nobody designs for: silence. Keys get lost. People go. The chain keeps the balance forever and gives it to no one. There is no help desk, no next of kin, no reset link. An address that goes quiet stays quiet, with everything still inside it.

an address with a successor.

Decessor lets an address name who comes next. You keep your address and your keys. Nothing is deposited, wrapped or held by anyone.

1. Delegate

   Point your existing EOA at the Decessor code with EIP-7702. Same address, same keys.

2. Name

   Choose one or more successors, in order, and a silence period of at least 30 days.

3. Pass on

   If you go quiet for longer than that, your first successor can claim. You still have 30 days to cancel.

silence is the only signal.

Every transaction you send through the delegated code resets your clock. A dedicated pulse() does the same without moving anything. If the silence runs out, the first successor can claim. Claiming opens a 30-day grace period during which one transaction from you cancels everything. After grace, the successor takes control.

configure(successors[], silence)        -> owner only ; silence >= 30 days
execute(to, value, data) / pulse()      -> owner only ; lastSeen = now
claim()                                 -> successor[i] only ; require now > lastSeen + silence + i * CASCADE_DELAY ; graceEnd = now + 30 days
cancel()                                -> owner only ; graceEnd = 0 (any owner transaction also cancels)
take()                                  -> claimant only ; require graceEnd != 0 && now > graceEnd ; control -> successor ; fee -> treasury

a lost key is no longer the end.

Name your own hardware wallet as your first successor. Lose the key to your everyday wallet and nothing is lost: wait out the silence, claim from the hardware wallet, and take control of the same address after grace. No seed phrase copies, no custodian, no support ticket. Inheritance comes second: put the people you trust behind you in the cascade.

the longest memory there is.

Succession is a promise measured in decades, so it belongs on the chain built to still be here. EIP-7702 lets an ordinary account run code without changing its address or giving up its key. Decessor needs nothing else: no custody, no oracle, no death certificate, no KYC. The chain never needs to know you are gone, only that you went quiet.

it earns only when it has served.

A fee in ETH is charged only at take(), on what passes on. Nothing while the owner is alive and active. A share of fees goes to $DCSR stakers, and holders govern the fee level, default delays and the treasury. Nothing fixed, nothing promised: what stakers earn depends only on real usage.

Fee

0.5% of the ETH passing at take()

Before take()

nothing

Stakers

a share of fees, from real usage only

• Silence is not death. Choose a long silence and a successor you trust.
• Successors can lose keys too. That is why there is a cascade.
• An EIP-7702 delegation is a phishing target. Verify the code hash before you sign.
• Experimental software. Bugs are possible.
• Privacy and inheritance rules differ by jurisdiction.
• Nothing here is financial advice.
