Lighter codebase means faster chain, right?
On CNBC, Sei co-founder Jeff Feng shares how the conversation with institutions has changed.
Education has given way to implementation. Institutional interest in Sei now centers on giving clients compliant access to tokenized assets.
Sei is secure.
ANALYSIS: @SeiNetwork is safe from a new collision attack vector targeting Lattice Hashes.
ePrint 2026/2083 describes a new collision attack on LtHash, the hash Sei's storage layer uses to fingerprint its data.
The attack finds two different states with the same LtHash in about 2^81 hashes. To succeed, it requires that those two states hold at least 550^8 entries between them. Roughly 8 sextillion.
Sei's state today has ~1 billion entries. A state big enough for this attack would be ~2 trillion times larger.
Even if Sei added a million brand-new entries every second, it would take about 130 million years before Sei was vulnerable.

After years trading oil derivatives at Goldman and leading DeFi at GSR, Monaco's CEO knows what a trading venue must get right.
Applying that, he built Monaco's order book on Sei for fast finality and reliability.

Ex-Goldman Oil Derivatives Trader Simran Singh (@0xturbanurban) on the day oil went to -$37.63, why every trading strategy is momentum or mean reversion, & losing $3.12M in a single day.

"You can't touch an interest rate curve, but you can smell a barrel of oil."
We cover:
- Pricing oil options at 300-400% vol the day WTI went negative
- How Goldman's oil desk monetizes client flow (80-85% was producers hedging)
- How producer hedges turned a market-risk problem into a credit problem in 2020
- Why market making is really a bet on mean reversion
- The perp funding trade: anyone can do it, very few can do it in size (15% carry even on the CME)
- "My size your price, or your size my price"
- Who's printing money right now: OTC hedging in power, compute & AI
- Why there's no venue to trade electricity, and how Monaco wants to fix that

Introducing the Giga Manifesto.
Tokenization needs a chain built for trading.
Giga, Sei's flagship product, is built to win tokenization as the world's markets move onchain.
Read more below.
Apollo, BlackRock, Brevan Howard, Hamilton Lane, Laser Digital, and Ondo already have tokenized products live on Sei.
Dinari is bringing 700+ tokenized U.S. stocks, including the entire S&P 500.
Giga arrives as upgrades to the live network, with no migration.
Read the Giga Manifesto: why tokenized markets need Giga, and how Sei gets there.
