mantra-common

Common Mantra Substreams modules to extract events and transactions with indexing This package inherits from the generic Cosmos Foundational Modules.

Usage

Usually, foundational modules are directly imported and used in other Substreams. All the official foundational modules are stored in substreams.dev.

specVersion: v0.1.0
package:
  name: my_project
  version: v0.1.0

imports:
  mantra: https://spkg.io/streamingfast/mantra-common-v0.1.0.spkg # Import the package from substreams.dev

modules:
  - name: my_events # Define your Substreams module
    use: mantra:filtered_events # Use the imported package
    initialBlock: 70000000

params:
  my_events: "(type:message && attr:action) || (type:wasm && attr:_contract_address)" # Pass the filter as parameter to the module

To run the Substreams:

substreams build
substreams auth
substreams gui

Modules

all_events (map)

Retrieves all the events in the Mantra blockchain without any filtering.

index_events (index)

The module create an index (a cache) to efficiently retrieve events by their type and/or attribute keys.

The module sets the keys corresponding to all event 'types' and 'attribute keys' in the block For example: type:coin_received, attr:action, attr:sender ...

The attribute values are never indexed because they have a high cardinality and would be too expensive to index.

filtered_events (map)

The module reads from all_events and applies a filter on the event types and attribute keys, only outputing the events that match the filter.

The filter is specificed in the parameters of the module.

...

params:
  filtered_events: "(type:rewards && attr:validator)"

filtered_event_groups (map)

The module reads from all_events and applies a filter on the event types and attribute keys, outputing all the events from transactions that have at least one event matching the filter.

params:
    filtered_event_groups: "type:rewards && attr:validator"

filtered_events_by_attribute_value (map)

The module reads from all_events and applies a filter on the event types, attribute keys and values, only outputing the events that match the filter.

NOTE: This module does not use the index created by index_events.

params:
    filtered_events_by_attribute_value: "type:rewards && attr:validator:mantravaloper18se5kq0z86pqfym8uuuqp77kyd788npj3wx7fc"

filtered_event_groups_by_attribute_value (map)

The module reads from all_events and applies a filter on the event types, attribute keys and values, outputing all the events from transactions that have at least one event matching the filter.

NOTE: This module does not use the index created by index_events.

params:
    filtered_event_groups_by_attribute_value: "type:rewards && attr:validator:mantravaloper18se5kq0z86pqfym8uuuqp77kyd788npj3wx7fc"

all_events reads from the sf.cosmos.type.v2.Block source and outputs a list of all events in the block. Some events are at the block level, others appear inside the transactions.
