ENCRYPTED

Autonomously settled the moment the window closes.

Pre-programmed cryptography executes your intentions autonomously, within strict mathematical limits you set in advance.

01

Deposit into your self-custodial locker

A dedicated smart contract vault holding your native ETH, Paxos USDG, or stablecoins on Arbitrum Sepolia and Robinhood Chain. You retain 100% control, private ownership, and withdrawal rights at all times.

02

Configure allocations & Cadence Streams

Designate heir addresses, shares, and streaming schedules. Cadence Streams deposits unvested inheritance into Aave v3's live Arbitrum Sepolia market for supported assets, earning real, verifiable interest — USDG-denominated vaults use a modeled rate pegged to USDG's own published yield.

03

Designate 2-of-3 Resilient Guardians

Designate trusted guardians who attest to inactivity status. Guardian Resilience includes non-custodial backup nomination to eliminate orphan lockouts, with zero access to balances or heir identities.

04

Set heartbeat interval & Stylus settlement

The moment inactivity is confirmed, a 72-hour reversible contest window opens. Final settlement executes autonomously via high-performance Arbitrum Stylus Rust WASM Merkle verification.

Security engineered for zero-trust inheritance.

Traditional paper wills leak plaintext, and centralized platforms can freeze accounts. Cadence replaces human intermediaries with immutable on-chain state machines, zero-knowledge proofs, and automated contest safeguards.

Deployed and verified on Arbitrum Sepolia, Robinhood Chain, and Ethereum Sepolia with 252/252 passing Foundry tests, 0 High/Critical findings in Slither 0.11.6 static analysis across 55 contracts, and Stylus Rust WASM verification.
01 // INVARIANTNON-CUSTODIAL

Assets remain strictly self-custodied

Funds remain deposited in your dedicated non-custodial smart contract locker. Cadence contracts hold zero privileged access to withdraw or liquidate assets without your valid signature or verified inheritance proof.

02 // INVARIANTCLIENT-SIDE ECIES

Allocations encrypted client-side

Beneficiary addresses, asset shares, and inheritance instructions are encrypted using browser-native ECIES (AES-GCM-256) before touching the network. Plaintext data never enters public mempools or RPC nodes.

03 // INVARIANTRESILIENT QUORUM

2-of-3 Resilient Guardian Quorum

Guardians attest to inactivity without access to balances or heir identities. Guardian Resilience introduces non-custodial backup nomination to eliminate single-point-of-failure orphan lockouts.

04 // INVARIANTREVERSIBLE SETTLEMENT

Reversible 72-hour Contest Window

Distribution cannot occur until the configured Contest Window expires. If guardians trigger prematurely, the owner can cancel with zero gas linkage via an off-chain EIP-712 stealth reset signature.

05 // INVARIANTCIRCUIT BREAKER

Anti-Drainer Stream Circuit Breakers

If an heir's wallet is compromised or drained, designated guardians or backup addresses can invoke pauseStream and redirectStream on-chain, redirecting all remaining inheritance to a secure cold wallet.

Keep the signal alive.
