Weeks like this remind me why we're here
Not just because of the market opportunity
Because payments are still broken for the people crypto was originally built for, and nobody is fixing that with the right values
Haven's privacy isn't one trick. It's three layers, each plugging a different leak.
1/ Stealth addresses (ERC-5564). Every payment lands on a fresh address. Whoever pays you never sees your real account, and nobody can chain your incoming payments together.
2/ Privacy Pools v2. Your balance sits in a shielded pool that breaks the public transaction graph. You can still prove your funds came from a legitimate source, in zero knowledge, without showing who you are.
3/ Split knowledge, off-chain. Your identity and your activity are never held by the same party. Not the ramp, not the card, not us.
Any one of these is a feature. The three together are infrastructure.
Crypto was built for two things: self-custody and privacy.
We had the first for a decade. The tech for the second just shipped.
Compliant privacy is finally ready, and the on-chain economy is about to feel like it was always supposed to.

A privacy card means rolling your own crypto?
The hard parts already exist and they work on @Starknet
Encrypted notes, value conservation, viewing keys, and a compliant audit path, all native to the protocol. Good tech!
The US just moved to open Federal Reserve payment rails to crypto firms.
Add it to the list: Brazil's Pix, Europe's stablecoin push, now the Fed. Payment rails are opening to crypto everywhere.
The missing piece starts with P ends with Y.
Ethereum direction is clear.
Account abstraction, FOCIL, shielded transactions, stealth address, Kohaku wallet SDK....
Privacy is moving from an add-on. Everyone should expect privacy by default.
The CLARITY Act on individual privacy it did two things:
1. banned a future CBDC
2. ordered studies on mixers
Nothing for the exposure that already exists
Every crypto card today links your card identity to your on-chain identity at the infrastructure layer.
Not a setting. It's how the system was built. Auth, wallet, settlement on the same trail. All queryable.
Once that link exists, everything downstream is negotiable. By regulators. By states. By anyone with a block explorer.
The fix isn't a privacy feature. It's a different architecture. More next week.
Wei Dai split privacy into two categories:
1️⃣Throttled: where you slow users down with deposit delays and limits, and
2️⃣Responsible: where the system only traces when something actually goes wrong.
We've been building in the responsible. Kinda like the name.
