2021-08-11 12:51:18 +00:00
The Ethermint client supports both [gRPC endpoints ](https://cosmos.network/rpc ) from the SDK and [Ethereum's JSON-RPC ](https://eth.wiki/json-rpc/API ).

### Cosmos gRPC and Tendermint RPC

2021-08-03 17:35:31 +00:00
Ethermint exposes gRPC endpoints (and REST) for all the integrated Cosmos-SDK modules. This makes it easier for
wallets and block explorers to interact with the proof-of-stake logic and native Cosmos transactions and queries:

### Ethereum JSON-RPC server
2020-07-17 18:07:05 +00:00
Ethermint also supports most of the standard web3 [JSON-RPC
2021-08-11 12:51:18 +00:00
APIs](./../api/JSON-RPC/running_server) to connect with existing web3 tooling.

2021-08-11 12:51:18 +00:00
See the list of supported JSON-RPC API [endpoints ](./../api/JSON-RPC/endpoints ) and [namespaces ](./../api/JSON-RPC/namespaces ).

To connect to the JSON-PRC server, start the node with the `--json-rpc.enable=true` flag and define the namespaces that you would like to run using the `--evm.rpc.api` flag (e.g. `"txpool,eth,web3,net,personal"` . Then, you can point any Ethereum development tooling to `http://localhost:8545` or whatever port you choose with the listen address flag (`--json-rpc.address`).
