The $ZAMA Public Sale is Here

A fairer way to launch a token. A smarter way to discover price. A sale built for real users, not bots.

Zama is selling up to 10% of the $ZAMA supply through a sealed bid single price Dutch auction on Ethereum, powered by the Zama Protocol. It uses the same auction design as Google’s IPO, now done on-chain with confidential bidding through FHE.

Everyone gets a level playing field. No gas wars. No front running. No pressure to rush your bid. You simply bid what you think the token is worth and the system settles at one fair clearing price.

How it works in three moves:

You shield USDC, USDT or DAI so your real buying power stays private. Shielded funds remain in your wallet but the amounts become encrypted.
You place bids with public prices and private quantities, and you can update or cancel them anytime during the auction.
The protocol computes the clearing price privately through FHE, fills all bids above it, fills bids at the clearing price pro-rata and refunds the rest.

The result is a cleaner distribution, stronger price discovery and a launch that does not tilt toward whales.

Tokens unlock immediately. The auction runs January 12 to January 15 2026 and claims to be open on January 20 2026.

ZAMA powers the Zama Protocol. It pays for encryption and decryption fees, supports staking and delegation and secures FHE coprocessors and KMS nodes. Mainnet is expected by year end, with ZAMA live before the sale.

If you want to join one of the most transparent token launches in crypto, this is your moment.

WHAT MATTERS

Citadel Urges SEC Crackdown on DeFi

State of play: Citadel Securities sent a letter urging the SEC to regulate DeFi protocols as full exchanges and broker dealers when they handle tokenized US equities.

The firm warned that giving DeFi broad exemptions would create two different rulebooks for the same securities and weaken protections.

The crypto community immediately pushed back:

Uniswap’s Hayden Adams accused Citadel of trying to clamp down on open, peer to peer systems that threaten TradFi market makers.
Blockchain Association CEO said the view is overbroad, unworkable, and ignores the basic difference of software devs and financial intermediaries.
She warned that treating DeFi builders like custodians would hurt US competitiveness and push innovation offshore.

Why it matters: Citadel is basically asking the SEC to pull DeFi into the same rulebook as Wall Street. If the agency bites, it could reshape how tokenized assets trade in the US and add real friction for open protocols.

Our take: This feels like Citadel protecting its turf. DeFi lowers barriers that TradFi relies on, so pushing for tighter rules is a predictable move.

For builders and investors: Stay ready for more scrutiny around tokenization.

INSIGHTS

Bitcoin’s Next Direction Hinges on MicroStrategy

Source: Strategy

JPMorgan analysts say MicroStrategy’s ability to stay financially stable without selling its BTC is now the biggest factor shaping BTC’s short term price.

Miner selling pressure is rising as hashrate falls, energy costs stay high, and BTC trades below its production cost, which JPMorgan now estimates at $90K.
Even so, the analysts argue that miners are not the main driver right now.
MicroStrategy’s enterprise value to bitcoin ratio is still above 1, which signals it is unlikely to be forced into selling.

Its new $1.44B cash reserve also covers two years of obligations, further reducing liquidation risk.

Markets are watching whether MSCI removes MicroStrategy from its equity indices.
JPMorgan says the downside is mostly priced in after a 40% share price drop since October.
If MSCI keeps the company in the indices, both MSTR and BTC could rebound sharply.
