The week of June 22 to June 28 brings a concentrated set of events across macro policy, technology, crypto infrastructure, exchange operations, and corporate financing. Last week, the United States and Iran signed a preliminary agreement, creating room for an extension of the ceasefire, the restoration of shipping through the Strait of Hormuz, and further nuclear talks. Against that backdrop, investors’ expectations for a further easing of Middle East tensions rose. Outside the geopolitical track, SpaceX is planning to issue at least $20 billion of bonds to replace a bridge loan, with its banking partners expected to speak with investors as early as next week.

Base, the Layer 2 network under Coinbase, is set to launch the Beryl hard fork upgrade. The upgrade introduces the B20 native token standard, shortens the final confirmation period for single-proof withdrawals from seven days to five days, and upgrades to Reth V2, which reduces disk usage by 50% and increases throughput by 33%. Beryl is scheduled to activate on the Sepolia testnet at 02:00 UTC+8 on June 19, and on the mainnet at 02:00 UTC+8 on June 26.
B20 is Base’s native token standard. It is an ERC-20-compatible token implemented as a Rust precompile and is designed for issuers of stablecoins, real-world assets, and long-tail tokens. The standard includes a compliance toolkit with transfer policies, freezing and seizure functions, role-based access control, memos, and supply caps. For withdrawals, the final ruling window for the single-evidence dispute resolution process will be reduced from seven days to five days. The dual-proof fast path introduced by Azul, based on TEE plus ZK, remains at one day.
June 26 onward: QKC network support and SpaceX bond financing
Binance also announced that it will stop supporting deposits and withdrawals of QuarkChain (QKC) tokens via the BNBSmartChain network at 16:00 Beijing time on June 26, 2026. After that time, deposits made through this network will not be credited to accounts and may result in asset losses. Users can still deposit and withdraw through other networks supported by Binance. No additional item was listed for June 28.
Under items with no specific confirmed time, people familiar with the matter said SpaceX (SPCX.O) and its partner investment banks may begin investor calls as early as next week to discuss a bond issuance after the company completes a record IPO. The bond sale is expected to be at least $20 billion, and investor communication could begin as early as Monday. The plan and timing remain subject to change.
SpaceX plans to issue investment-grade US dollar bonds for the first time. Proceeds from the bond sale will be used to replace a $20 billion bridge loan maturing in September 2027. SpaceX’s IPO filing with the US Securities and Exchange Commission shows that, as of March 31, the bridge loan made up the bulk of the company’s $29.1 billion in long-term debt. People familiar with the matter said Bank of America, Citi, JPMorgan, Goldman Sachs, and Morgan Stanley jointly provided the bridge loan and will lead the underwriting of the bond issuance.
