Important Announcement for your Integrations with Polkadot and Kusama Ecosystem chains

The Polkadot ecosystem has recently voted in favor of unifying the address format in the Polkadot ecosystem. This will imply certain UX changes on how human readable addresses are displayed in the Polkadot ecosystem. In short, addresses in any blockchain in Polkadot ecosystem will have the same representation as the one in the Relay Chain.

For example, for the Polkadot ecosystem, the prefix of the SS58 address format of every parachain will be set to 0 so that it matches with the one on Polkadot Relay Chain:

impl frame_system::Config for Runtime {
...
--- type SS58Prefix = SS58Prefix;
+++ type SS58Prefix = 0u16;
...
}

You can find a list with examples for all the relevant blockchain / tokens here. We believe you currently support one or more of the blockchains / tokens listed in the previous list, so this change is also relevant for your services. You can expect that customers in your platforms will start providing the new address format for deposits or withdrawals starting January 2025.

Please let us know if you have any question or concern regarding this process.
