May 18 — Multiple media reports indicate that U.S.-Iranian negotiations on key issues remain at an impasse, with the two sides still holding significant differences over core matters including the nuclear program, terms for ending hostilities, and unfreezing Tehran’s frozen assets, though limited adjustments have been made to some technical arrangements. Sources say the U.S., in its latest proposal, has offered to permit Iran to conduct restricted peaceful nuclear activities under International Atomic Energy Agency (IAEA) supervision and is considering phased unfreezing roughly a quarter of Iran’s frozen offshore assets. For its part, Iran is insisting on full sanctions removal and the return of all related assets, while opposing any linkage between the nuclear issue and ceasefire conditions. In terms of the negotiation framework, Iran has put forward a plan to accept a long-term freeze of its nuclear program but has rejected complete dismantlement; Tehran also proposes transferring

On May 18, Hyperliquid’s native token HYPE defied the broader crypto market slump, climbing over 5% in value. The token has now surged a remarkable 69% year-to-date, and market attention is firmly fixed on its HIP-3 pre-IPO perpetual contract ecosystem, which has racked up over $120 billion in trading volume. Per reports, Hyperliquid has rolled out pre-listing perpetual contracts tied to upcoming IPOs of top AI firms, including SpaceX, Anthropic, and OpenAI. For context: The Cerebras perpetual contract launched by TradeXYZ has a price gap of only ~3% from its Nasdaq opening listing price—compared to a 35% deviation seen in traditional secondary markets. Right now, Hyperliquid hosts SpaceX’s pre-IPO contract (ticker: SPCX), which carries a reference valuation of roughly $1.78 trillion. Analysts project SpaceX’s IPO could raise between $750 billion and $800 billion, while both Anthropic and OpenAI are targeting $1 trillion-plus valuations for their public offerings.

On May 18, Solana development firm Anza announced a formal recommendation for mainnet validators to upgrade to Agave 4.0. This update brings key improvements: XDP support for Turbine, QUIC-only TPU data access, a faster replay stage, and multiple SIMD features that will roll out in this cycle. Anza noted that production testing with large mainnet validators found XDP cut Turbine retransmit latency from about 600ms to roughly 0.8ms, giving Solana critical performance breathing room to scale to 1 billion compute units (CUs) per block. Additionally, Agave 4.0 completely removes UDP transaction access, making QUIC the sole transaction submission method. The update also shifts PoH entry validation and Ed25519 signature verification off the critical path, processing those tasks asynchronously to boost replay stage performance. This upgrade will also gradually roll out several SIMD features, including p-token—an SPL Token alternative that frees up approximately 13% of block capacity—Stake

May 18 — Al Jazeera, citing U.S. sources, reports that Iran has only days, not weeks, to present something to President Trump to break the diplomatic deadlock. With negotiations with Iran moving at a snail’s pace, President Trump’s patience is wearing thin. If no breakthrough is achieved in the coming days, the president is inclined to take military action.
