Today, Polkadot officially announced its token DOT claim website DOT Claim, as well as a tutorial for claiming it. The tutorial shows that there are four steps to make an appointment to collect your purchased DOT. The first step is to check the Ethereum address, the second step is to generate a Poca address, the third step is to use MyCrypto software to claim the DOT to complete the mapping, and the fourth step is to check the address, amount, etc to confirm the claim. It is worth noting that this website is only used to claim DOT before Boca going online. The method of claiming will change after Boca goes online. According to the announcement, based on experience, Boca's launch is not far away.
