Short Description:

Support Colorful Notion’s Polkaholic.io open source XCM/Multichain block explorer, indexing of all Polkadot + Kusama + parachain data with a special emphasis on XCM Transfers / Messages, made available in UI/API/CDN/BigQuery form to support Polkadot ecosystem’s multichain initiatives.

Proposal Summary:

Colorful Notion proposes to:

• Expose and maintain public archive of all the raw data indexed by Polkaholic.io (blocks, extrinsics, events and traces) available in CDN form and then in BigQuery form and indexed data (specifically and especially XCM transfers and XCM messages) in API form
• Continue to index all Polkadot chains to the fullest extent possible to generate and maintain the archive with APIs, which may be relied upon by large scale archival systems. These APIs maintain Value transfers/XCM transfers according to DEX info on top “defi” parachains
• Model XCM Transfers and Messages across the entire Polkadot/Kusama ecosystem
• Enhance Polkaholic.io indexing as the Polkadot ecosystem expands: New parachains, new pallets generating XCM extrinsics/messages with new XC Assets, support for ERC20/PSP22/ERC721/PSP34 assets, XCMv3, and new bridges
