New feature: hidden inheritance on Ethereum with ERC-7984 and @zama
Your PIN is your proof of life. Stop entering it for months and your heirs inherit. One correct PIN during the grace period cancels it.
β Who your heirs are, what they get, even how many there are: all encrypted. Not even you can look it up later.
β Each heir gets a printable card with a QR code and a secret claim code. Keep it with your will.
β When the time comes, they scan it and claim to any wallet they like, even a brand new one.
β Anyone can hit claim. Heirs get their share, everyone else an encrypted zero, and from the outside it all looks the same.
β Key stolen and you had to escape? The will comes with you to your backup address.
The Sepolia demo runs on 5-minute timers so you can try the whole flow π

I built Encrypted Accounts on Ethereum with @zamaView quoted post on X
Most wallet security trusts something outside the chain:
2FA β trusts your phone
Email recovery β trusts your inbox
Hardware wallet β trusts a device
I wanted something different. So I put a 6-digit PIN check inside the smart contract, encrypted with FHE.
Anything unusual (new address, big amount) and the contract asks for your PIN.
Seed phrase leaked?
Key stolen?
Email hacked?
Doesn't matter, they still can't steal your funds.
"But 6 digits is easy to brute force"
Not here. Every guess gets counted on-chain before the answer comes back, and the waits keep growing. That's ~12 tries a month, max. And your PIN never leaves your device.
A few more things it does:
β your limits and trusted addresses are encrypted, so a thief can't even see the rules
β phishing signatures are useless, a permit signed with the key alone is void
β key leaked? hit escape and after 30 days everything goes to your backup address
What I'm working on next:
β Steal this wallet: a funded Sepolia account with a public seed phrase. Take it if you can
β private transfers + a duress PIN
β hidden inheritance
β AI agents that hold the key while you hold the PIN
It's a research prototype, live on Sepolia, not audited yet. Open source.

Really like what @Helius shipped with Privacy Rings.
Private transfers settle in one Solana transaction. No sequencer, no L2, full Solana speed. Amounts are hidden, and so is which token moved.
Prove locally and nothing private leaves your machine, or use their TEE prover if you'd rather not run one.
Congrats to the team π
We need a lot more privacy apps and infra.

Today, Solana changes forever
Introducing Solana Privacy Rings - encryption at the speed of Solana
Rings are programmable, onchain environments for encrypting money, markets, and finance - without ever leaving Solana

encrypted-account.vercel.app Encrypted Account β a stolen key isn't enough A smart account whose PIN lives in the contract, checked under FHE. Limits and trusted addresses stay encrypted, even from whoever holds the key. Try it on Sepolia. Bug bounties are drowning in AI spam. curl shut its own down in January.
So I built one that doesn't read reports. It runs them.
Agents are welcome. Spam isn't.
Prove the bug, and NEAR pays automatically.
