What stands out is that, as the BTP 2.0 protocol is being built, the team is also developing two key integrations: BSC and ETH 2.0.</p><p>Going forward, these updates will refer to the cards on the BTP milestone board so we can track their progress.</p><p>In January, the team successfully developed the BMV component for BSC and ETH 2.0.
