v1.2.0

Release v1.2.0 Highlights

• Indexing of blockchain-specific IBC Denom Trace Metadata: A new feature has been released that enables the indexing of blockchain-specific IBC Denom Trace Metadata. This allows for better tracking and analysis of inter-blockchain communication Denoms and use in downstream functionality.
• Indexer support for IBC MsgRecvPacket and successful MsgAcknowledgement: The indexer has been updated to include support for IBC MsgRecvPacket and successful MsgAcknowledgement transaction types. This enables better tracking and analysis of inter-blockchain communication and improves overall indexing functionality.
• Generalized BeginBlock and EndBlock event indexing: The indexer now has enhanced support for handling generalized BeginBlock and EndBlock block events. This includes specific support for Tendermint Liquidity module block events and Osmosis Incentives rewards. These improvements provide more comprehensive indexing capabilities.

Changelog

v1.1.0

Release v1.1.0 Highlights

​

1. Continued improvement and extension of tax software CSV output formats: This release contains several extensions and improvements to the tax software CSV output capabilities, offering continued support for previously supported formats and including support for new formats. Of note is the application's new support for CryptoTaxCalculator. This means that users who are using CryptoTaxCalculator to calculate their cryptocurrency tax liabilities can now directly use data processed by the Cosmos Indexer tool, making it easier and more efficient for them to calculate their taxes.
2. Added multi-handler support for message parsing to allow fallbacks for alternate message formats with the same URL: This change makes Cosmos Indexer more flexible and robust by allowing it to handle multiple message formats from the same type URL. In practice, this means that if one of the supported message types comes in multiple different formats based on chain history, it can fall back to an alternate handler that can process that format. This reduces the likelihood of data being missed or incorrectly processed due to format differences.
3. Extended support for new block event and transaction message types: This release contains continued indexer extension of various block events and transaction message types. The methodology of event and transaction indexing has been extended to support a wider range of available data types, indicating an increased level of fidelity to on-chain data points.
4. Improved chain querying methods: The indexer has been extended with improved RPC querying methods for transaction data. A fallback mechanism has been developed to deal with inconsistent on-chain RPC responses due to various issues that are possible in the Cosmos ecosystem (for example, deprecation and removal of old message types from blockchain specifications). This will ensure proper handling for various different problems that can arise when dealing with old history.

v1.0.0

Initial Release and public launch of Defiant's cosmos-indexer

Now that all the initial grants have expired, Defiant will continue to develop and improve this tool from here on out.

v0.2.0
