The coming week also includes South Korea’s rollout of revised artificial intelligence guidelines for the financial sector, Micron Technology’s latest earnings and guidance, a batch of US economic indicators, a US House roundtable on digital finance, several Binance trading-rule changes, Base’s Beryl mainnet hard fork, and discussions around SpaceX’s planned bond sale of at least $20 billion.

Base, the Layer 2 network under Coinbase, is preparing to launch the Beryl hard fork upgrade. Beryl introduces the B20 native token standard, reduces the final confirmation period for single-proof withdrawals from seven days to five days, and upgrades Reth V2. According to the source item, the Reth V2 upgrade reduces disk usage by 50% and increases throughput by 33%. The Beryl upgrade is scheduled to activate on the Sepolia testnet at 02:00 on June 19, UTC+8, and on the mainnet at 02:00 on June 26, UTC+8.
B20 is Base’s native token standard. It is an ERC-20-compatible token implemented through Rust precompiles and is designed for issuers of stablecoins, real-world assets and long-tail tokens. It includes a built-in compliance toolkit covering transfer policies, freezing and seizure, role-based access control, memos and supply caps. On withdrawals, the final adjudication window for the single-evidence dispute-resolution process is shortened from seven days to five days. The dual-proof fast path introduced by Azul, combining TEE and ZK, remains at one day.

After 16:00 Beijing time on June 26, 2026, deposits made through that network will not be credited to user accounts and may result in asset losses. Users can still conduct deposits and withdrawals through other networks supported by Binance. The June 28 section of the original calendar lists no specific items.
Undated item: SpaceX’s bond sale of at least $20 billion
Among items without a fixed date, people familiar with the matter said the banking team working with SpaceX, listed in the source as SPCX.O, could begin investor calls as early as next week. The discussions relate to a bond issuance plan after the company completes a record-setting IPO. The sources said 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. The proceeds will be used to replace a $20 billion bridge loan that matures in September 2027. According to the IPO filing SpaceX submitted to the US Securities and Exchange Commission, that bridge loan accounted for the bulk of the company’s $29.1 billion in long-term debt as of March 31. The sources said Bank of America, Citi, JPMorgan, Goldman Sachs and Morgan Stanley jointly provided the bridge loan and will lead the underwriting of the bond sale.
