Namadexer is an indexer for Namada.

The project is composed of 2 entities : the indexer and the server. They are both written in Rust.

• the indexer: it connects to the Namada node through rpc and collect the blocks and transactions. Then it stores them in the postgres database. The indexer doesn't know about the server and can be started independently.

• the server: it is a JSON server that allows querying block and transaction using unique identifier. Other useful endpoints like /blocks/latest can be found too. A list of all the endpoints and their description can be find in the documenttaion.

Those services requires a connection to a postgres database. Support for OpenTelemetry was also added.

You can find more information about the indexer in the ./docs folder.

You will need access to a namada node and inform its tendermint rpc host and port in the Settings.toml file. You can use the Settings.example.toml as a template.

You will need rust installed and a running node of namada accessible locally.

It will install teh right version of protoc (at least 3.12) in this repo to avoid conflict with other installed version

$ make install-deps

Start the docker database :

$ make postgres

You will need to use this command if you want to avoid issues with protoc.

$ make run

Run jaeger in background

$ docker run -d -p6831:6831/udp -p6832:6832/udp -p16686:16686 -p14268:14268 jaegertracing/all-in-one:latest
