An on-chain lending market has no rate-setting committee. It has a curve, published in advance, that converts one observable number into the price of credit — and the shape of that curve encodes every decision the protocol has made about who it is protecting.

Bitcoin trades near $86,000 ahead of a $15.9 billion Deribit options expiry, while Senate Republicans unveil a revised CLARITY Act aimed at winning Democratic support for U.S. crypto market-structure rules
US spot Bitcoin ETFs pulled in $714.7 million on September 23, extending a four-day inflow streak, even as the Senate's crypto market-structure bill remains stalled and the SEC works on new custody rules.
Bitcoin pushed to its highest level in weeks after a short squeeze wiped out $648 million in bearish bets, while the SEC's tokenized stock pilot is set to open on September 22. Here is what both developments mean for U.S. investors.
Washington drew a hard line on Iran-linked crypto infrastructure this week, while Coinbase moved to put digital assets inside thousands of community bank apps. Together, the two stories show how the US crypto perimeter is being redrawn.
Bitcoin shook off the Federal Reserve's first rate hike in three years to reclaim $76,000, even as Washington sent mixed signals on crypto policy — one bill advancing through House committees days after the CLARITY Act stalled in the Senate.
The CLARITY Act failed a key Senate cloture vote just as Bitcoin slipped toward $76,000 and the Fed prepares to announce its rate decision — here's how the two stories connect.
Bitcoin dropped under $77,000 on September 11 as a hotter-than-expected PPI reading and rising Treasury yields triggered nearly $500 million in liquidations, even as the U.S. Senate locked in a September 15 vote that could reshape crypto regulation.
Bitcoin pulled back from a fresh 2026 high after a hot US inflation print, but two other signals kept the American crypto market's growth story intact this week: a seventh straight day of spot Bitcoin ETF inflows and a new SEC custody proposal now sitting with the White House for review.
Borrowed from banking, the travel rule pushes crypto firms to exchange identifying information on transfers. We explain the mechanics and the friction it creates.
Liquidity is the quiet force behind how smoothly crypto trades fill and how violently prices can move. Here is why it deserves more attention.
High-profile platform failures keep reviving the self-custody debate. We explain the trade-offs between holding your own keys and trusting an exchange.
Smart contracts are what make Ethereum programmable, but flawed code remains one of the ecosystem's defining risks. Understanding why helps users interact with applications more safely.
Bridges connect otherwise isolated blockchains, but they have repeatedly proven to be one of DeFi's most vulnerable components. Here is what users should know.
Ethereum's open design hands users full control of their funds, which also means full responsibility for security. Strong wallet habits are the difference between safety and loss.
Of all crypto-assets, stablecoins attract some of the strictest oversight. We explain why their money-like behavior and redemption promise put them in a category of their own.
