Base unveils Beryl upgrade with native B20 token standard

Tokens issued through B20 behave like standard ERC-20 assets, meaning applications do not need a separate integration. Base also plans to let users pay transaction fees with B20 tokens instead of ETH and create virtual deposit addresses. Users will be able to access balances and transfer histories directly through node calls.

The network expects native execution to eventually make transfers about 50% cheaper and double transfer throughput.

Beryl will also cut the standard withdrawal delay from Base to Ethereum from seven days to five. Azul introduced a one-day withdrawal path when two proof systems confirm a transaction. Base said that path is rarely used because generating the required zero-knowledge proof remains expensive. Beryl instead reduces the delay for the more common single-proof process. Base said the five-day window still provides time to detect and disable a faulty prover before funds are released.

Reth V2 will reduce disk usage across full, minimal, and archive nodes while improving how quickly nodes calculate state roots. Base said the changes will allow it to raise block gas targets and limits without overloading its sequencer or node infrastructure.

Users will not need to take any action. Node operators must update to the latest software before Beryl activates on June 25.

Base's next upgrade, Cobalt, is targeted for September. Expected features include native account abstraction and expanded B20 functionality. The upgrade will also combine the network's consensus and execution clients into a unified node binary.
