Migration of pD223 from Callisto to D223 on Ethereum

DEX223, a DeFi protocol promoting ERC-223 for the Ethereum ecosystem and EVM-compatible blockchains, has completed the migration of pD223 tokens sold during the presale ICO round from the Callisto network to the Ethereum network.

Effortless Migration for Users

DEX223 implemented a model where users were not required to perform any actions or pay fees. All they had to do was hold their pD223 tokens in their accounts at the time of the blockchain snapshot.

This approach was chosen for two main reasons:

Error Prevention: Eliminating the risk of user mistakes and minimizing repetitive support requests or conflict resolution efforts.
Rewarding Early ICO Participants: While transaction fees on the Callisto network are minimal, Ethereum’s fees, particularly during market booms, can be significantly higher. By covering distribution costs, DEX223 ensured the migration remained entirely free for users.

Holders of pD223 on Ethereum received the updated D223 tokens, sparing them the need for manual upgrades or associated costs.

D223 New Version

"Evolution favors adaptability." This principle applies not only to biology but also to business and software development, where flexibility and adaptability are critical.

In early November, the DEX223 team introduced the updated D223 token while maintaining the ERC-223 standard's core philosophy of security.

It’s important to note that the upgrade focuses on enhancing functionality. Over seven years, the reference ERC-223 contract has been refined to perfection before its adoption as an Ethereum standard.

Two New Features:

Transaction Tracking in Block Explorers:
Previously, ERC-223 transactions were not displayed in block explorers designed for ERC-20 tokens due to differences in transaction methods. Despite submitting a request to Etherscan, the team proactively modified the original contract code for compatibility with all block explorers.
Support for Native Blockchain Coin Transfers:
Along with token transfers, it’s now possible to send the blockchain’s native coin, enhancing functionality for developers and end-users. For example, DeFi protocols that accept mixed payments in tokens and native coins can now benefit from this feature.

Upgrading Legacy D223 Tokens

Legacy D223 tokens purchased during ICO rounds or private sales on Ethereum can be upgraded using:

Direct Token Transfer to the Contract.
Special Webpage for Upgrades.

Snapshot Report and Dispute Resolution

A list of valid addresses and token amounts for migration between blockchains was published on GitHub. Users can leave comments on the same page to resolve potential disputes, such as addresses mistakenly excluded from the snapshot.

Conclusion

The migration of presale tokens from Callisto to Ethereum is a promising development for D223 holders. Both the migration and D223 upgrade are essential milestones ahead of the DEX223 launch and D223’s listing on centralized exchanges (CEXs).
