Woofun AI reports that Coinbase-backed Base is set to activate the B20 token standard on its mainnet, establishing a native framework for stablecoins, real-world assets (RWAs), and other fungible tokens.

The standard goes live at 6 pm UTC, introducing two distinct variants: an asset variant with configurable decimals between six and 18, and a stablecoin variant fixed at six decimals requiring fiat denomination like the US dollar or euro. This deployment is part of the Beryl upgrade, which launched on June 26 after shortening withdrawal waiting periods from seven days to five days to enhance network performance.

Woofun AI data shows that B20 tokens include built-in issuer controls such as supply limits, transfer rules, minting, burning, pausing, and transaction notes, allowing developers to bypass custom ERC-20 contract audits.

However, this activation follows significant instability; on June 25, a consensus issue caused an invalid block, halting production for nearly two hours. A subsequent sequencer bug triggered an 116-minute outage, followed by a 20-minute halt due to a race condition after a system reset on June 26. The Beryl upgrade itself was delayed by one day due to a B20 activation registry timing issue.

Developers can now utilize these native standards without building custom contracts, though the recent post-mortem highlights ongoing challenges in block production stability. This marks a critical test for the network’s reliability as it scales token issuance capabilities.
