PANews reported on February 24 that according to CoinDesk, a few hours after Coinbase released the Ethereum L2 network Base test network, the network experienced a malfunction. Twitter user @0xfoobar attached a screenshot of Etherscan’s transaction list and said: " Base’s bridge got off to a rocky start. Every transaction was being restored, and the bridge contracts were all unverified, so no one could figure out what was going on.” Some of those transactions appear to have resumed, though. Coinbase said the operational glitch on the testnet was caused by an issue with the Coinbase wallet, which misestimated the gas fees required to execute user transactions. Therefore, the user pays less gas than is required to execute the transaction, which prompts Base to resume these transactions rather than process them.
Coinbase software engineer Roberto Bayardo explained on Twitter a few hours after the release: “Should be fixed now. Bridge contract increased gas usage under load, which wallets didn’t estimate correctly. Hardcoded higher gas limit now.” According to Bayardo, the sudden influx of users may have overwhelmed the protocol and was one of the reasons for the problems on the testnet launch day.
In addition, a Twitter user discovered that the Base team initially promised on its website to donate 20% of Sequencer revenue to "fund public products," but later deleted the percentage and updated it to Base will contribute an undisclosed percentage to public products, or "a portion of Sequencer revenue." A representative of Coinbase said that the 20% figure has been removed from Base's website because it is working with the Optimism Collective to finalize the amount of revenue allocated to public products.
