In a big finance deal this week, Arbelos Markets got $28 million for their trading business focusing on crypto deals. Dragonfly led the funding, with FalconX, Circle Ventures, Paxos, and Deribit also joining in.

Derivatives are special deals that get their worth from something else. Examples include put and call options, and futures contracts. A new type, perpetual futures, has no end date and is super risky.

Arbelos is more serious and professional than some other crypto firms. CEO Joshua Lim says they're smart with their money and have good products. Brett Harrison, ex-CEO of FTX.US, is working on something similar.

Arbelos doesn't do brokerage but provides tools for trading assets like derivatives. They'll use the money to improve their systems, hire people, and offer more products.

They're trying to show they're safer than other crypto firms that took big risks and caused problems in 2022.

Founders Fund, led by Peter Thiel, put $13.2 million into Lagrange, a startup working on privacy tech. Other investors include Archetype Ventures, 1kx, Maven11, Fenbushi Capital, Volt Capital, CMT Digital, and Mantle Ecosystem Fund.

Lagrange is making a special chip to keep data private, especially for blockchains. They've made a tool for Ethereum, which handles a lot of data, to keep things private.

In summary, Arbelos got a big investment for their finance work, while Lagrange got funding for their privacy technology. These moves show big interest in both finance and privacy tech.
