How it works

How it works

A simple and secure flow to protect your digital assets.

01
01

Connect your wallet

Link your compatible Ethereum wallet. Arka only reads the public address, never touches your private keys.

02
02

Define beneficiaries

Assign destination wallets and percentages for each asset. You decide who receives what.

03
03

Inactivity detection

The heartbeat monitors your activity. If you stop responding, the contract prepares to execute.

04

Automatic execution

The smart contract transfers assets directly to beneficiaries. No intermediaries, no delays.

Security without compromise

Security without compromise

No custody

Arka never controls your funds. The smart contract is the only temporary custodian.

No key storage

Your private keys never touch our servers. Zero-knowledge by design.

Full control

You can revoke, modify or cancel at any time while you are active.

Transparent and auditable

The contract is open source and verifiable on the blockchain by anyone.

Gas fees by user

Network fees (gas) are paid by the user when setting up and executing the contract.

ARB

Arbitrum — minimal gas

We operate on Arbitrum to minimize gas costs while maintaining Ethereum security.
