Upbit will suspend PROS deposits and withdrawals at 6:00 a.m. UTC on Sept. 29 to support the Pharos hard fork. Binance will suspend deposits and withdrawals for tokens on the Base network at about 17:00 UTC on Sept. 30, 2026, before Base’s Cobalt upgrade and hard fork expected around 18:00 UTC. Trading will remain available, and Binance will handle the technical requirements before reopening Base-network transfers once the upgraded network is stable. Cobalt enhances the B20 token standard, introduces validity transactions and dynamic node upgrades, and moves Trusted Execution Environment signer registration to onchain attestation verification. A separate Denim upgrade is planned for October 2026.
