API Documentation

There are a few ways to access the Cronos POS Chain

1. Tendermint RPC

• Raw but most-completed data

• Hosted documentation (use the latest master only): https://docs.tendermint.com/master/rpc/

• Swagger file: https://github.com/tendermint/tendermint/blob/v0.34.3/rpc/openapi/openapi.yaml

1. gRPC Based

• Processed chain information. Old state may be pruned from time-to-time. To avoid state pruning, update pruning = "nothing" in ~/.chain-maind/config/app.toml

• There are two query methods based on gRPC:

  1. gRPC Server
  2. gRPC Proxy RESTful Server
