A quiet promise
on-chain.
ChainWill is a simple way to make sure the people you love can reach your crypto if you can't. No lawyers. No custodian. Just a contract that listens.
Non-custodial Open-source contract Permissionless execution
How it works
Four steps. One peace of mind.
You stay in control the whole time. Your funds never leave your wallet until the contract proves you've stopped checking in.
01
Connect
Link your wallet via RainbowKit — MetaMask, Coinbase, WalletConnect, etc.
02
Approve & assign
Pick ERC-20s to will and a single beneficiary. Deposit ETH if you want it covered too.
03
Check in via email
Reply to a monthly email with a gasless signature — or call signAlive() yourself.
04
Silence triggers it
After your chosen grace period (30–180 days), anyone can execute. Permissionless.

Built to be boring
Verifiable, by design.
Every action runs through a single, audited smart contract. We can't move your funds. Neither can a court order on us. Only the contract — and only after you've gone quiet for the grace period you set.

Frequently asked
The questions everyone asks first.
Your grace period is whatever you set it to (30 to 180 days). Within that window, signing any check-in resets the timer. Once it expires, anyone can call executeWill(yourAddress) on the contract — it's permissionless.
