+# Kava gRPC Client
+
+The Kava gRPC client is a tool for making gRPC queries on a Kava chain.
+
+## Features
+
+- Easy-to-use gRPC client for the Kava chain.
+- Access all query clients for Cosmos and Kava modules using `client.Query` (e.g., `client.Query.Bank.Balance`).
+- Utilize utility functions for common queries (e.g., `client.BaseAccount(str)`).
+
+## Usage
+
+### Creating a new client
+
+```go
+package main
+
+import (
+  kavaGrpc "github.com/0glabs/0g-chain/client/grpc"
+)
+grpcUrl := "https://grpc.kava.io:443"
+client, err := kavaGrpc.NewClient(grpcUrl)
+if err != nil {
+  panic(err)
+}
+```
+
+### Making grpc queries
+
+Query clients for both Cosmos and Kava modules are available via `client.Query`.
+
+Example: Query Cosmos module `x/bank` for address balance
+
+```go
+import (
+  banktypes "github.com/cosmos/cosmos-sdk/x/bank/types"
+)
+
+rsp, err := client.Query.Bank.Balance(context.Background(), &banktypes.QueryBalanceRequest{
+		Address: "kava19rjk5qmmwywnzfccwzyn02jywgpwjqf60afj92",
+		Denom:   "ukava",
+	})
+```
+
+Example: Query Kava module `x/evmutil` for params
+
+```go
+import (
+  evmutiltypes "github.com/0glabs/0g-chain/x/evmutil/types"
+)
+
+rsp, err := client.Query.Evmutil.Params(
+  context.Background(), &evmutiltypes.QueryParamsRequest{},
+)
+```
+
+#### Query Utilities
+
+Utility functions for common queries are available directly on the client.
+
+Example: Util query to get a base account
+
+```go
+kavaAcc := "kava19rjk5qmmwywnzfccwzyn02jywgpwjqf60afj92"
+rsp, err := client.BaseAccount(kavaAcc)
+if err != nil {
+  panic(err)
+}
+fmt.Printf("account sequence for %s: %d\n", kavaAcc, rsp.Sequence)
+```
+
+## Query Tests
+
+To test queries, a Kava node is required. Therefore, the e2e tests for the gRPC client queries can be found in the `tests/e2e` directory. Tests for new utility queries should be added as e2e tests under the `test/e2e` directory.

+		Short: "Strip all blocks from the database outside of a given range",
+		Long: `shard opens a local kava home directory's databases and removes all blocks outside a range defined by --start and --end. The range is inclusive of the end block.
+
+It works by first rolling back the latest state to the block before the end block, and then by pruning all state before the start block.
+
+Setting the end block to -1 signals to keep the latest block (no rollbacks).
+
+The application.db can be loaded at a particular height via the --force-app-version option. This is useful if the sharding process is prematurely terminated while the application.db is being sharded.
+
+The --only-app-state flag can be used to skip the pruning of the blockstore and cometbft state. This matches the functionality of the cosmos-sdk's "prune" command. Note that rolled back blocks will still affect all stores.
+
+Similarly, the --only-cometbft-state flag skips pruning app state. This can be useful if the shard command is prematurely terminated during the shard process.
+
+The shard command only flags the iavl tree nodes for deletion. Actual removal from the databases will be performed when each database is compacted.
+
+WARNING: this is a destructive action.`,
+		Example: `Create a 1M block data shard (keeps blocks kava 1,000,000 to 2,000,000)
+$ kava shard --home path/to/.kava --start 1000000 --end 2000000
+
+Prune all blocks up to 5,000,000:
+$ kava shard --home path/to/.kava --start 5000000 --end -1
+
+Prune first 1M blocks _without_ affecting blockstore or cometBFT state:
