Your switches

Release is automated.
A keeper bot (Chainlink Automation in production) calls release() the second your switch trips. You don't need to click anything. Your heirs are paid out automatically.

How it works

Three steps. Zero middlemen.

01

Lock & name heirs

Deposit USDC or EURC into your switch and list beneficiaries with payout shares in basis points.

02

Check in to stay alive

Press 'I'm alive' inside your check-in window. One click resets the countdown. No signature gymnastics.

03

Silence triggers release

If you go past the deadline, a keeper bot calls release() and your stablecoins flow to your heirs onchain.

Why Arc

Built on Circle's USDC-native chain.

Inheritance is a long game. You need a chain where the unit of account doesn't swing, gas is predictable, and the funds settle before you can blink.

You stay in control

Withdraw, deposit, or edit heirs at any time, until silence.

USDC & EURC

Lock in dollars or euros, with native Circle stablecoins on Arc.

Fully verifiable

Open-source contract. Every check-in, deposit, and release is on-chain and auditable.

FAQ

Common questions.

Your switch trips when the current time passes lastCheckIn + checkInInterval. A keeper bot then calls release() and your stablecoins are distributed to your beneficiaries according to their shares. You can set generous intervals (up to 1 year) to reduce this risk.
