L2Beat Head of Research Donnoh stated that Robinhood Chain uses a highly permissioned canonical bridge architecture, and its fraud proof system doesn’t seem to be fully open. He questioned why it still retains the 7-day withdrawal challenge period. He mentioned growing doubts about whether some L2s view long withdrawal periods as a feature rather than purely a security requirement. Robinhood Chain’s official documentation still indicates that its withdrawal process requires waiting for Arbitrum’s standard 7-day challenge period. https://www.(wublock123.com)/news/l2beat-head-researcher-says-some-layer2s-treat-long-withdrawals-as-product-feature-64332
