Below is a list of the RPC methods, the parameters and an example response from the namespaces.

## Web3 Methods

### web3_clientVersion

Get the web3 client version.

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":67}' -H "Content-Type: application/json" http://localhost:8545

// Result
 {"jsonrpc":"2.0","id":1,"result":"Ethermint/0.0.0+/linux/go1.14"}
```

### web3_sha3

Returns Keccak-256 (not the standardized SHA3-256) of the given data.

#### Parameters

- The data to convert into a SHA3 hash

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"web3_sha3","params":["0x67656c6c6f20776f726c64"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":"0x1b84adea42d5b7d192fd8a61a85b25abe0757e9a65cab1da470258914053823f"}
```

## Net Methods

### net_version

Returns the current network id.

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"net_version","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":"8"}
```

## Eth Methods

### eth_protocolVersion

Returns the current ethereum protocol version.

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_protocolVersion","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":"0x3f"}
```

### eth_syncing

The sync status object may need to be different depending on the details of Tendermint's sync protocol. However, the 'synced' result is simply a boolean, and can easily be derived from Tendermint's internal sync state.

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":false}
```

### eth_gasPrice

Returns the current gas price in aphotons.

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":"0x0"}
```

### eth_accounts

Returns array of all eth accounts.

```json
// Request

```

### eth_sign

The sign method calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).

By adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.

::: warning 
the address to sign with must be unlocked.
:::

#### Parameters

- Account Address 

- Message to sign

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x3b7252d007059ffc82d16d022da3cbf9992d2f70", "0xdeadbeaf"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

``` -->

### eth_getLogs

Returns an array of all logs matching a given filter object.

#### Parameters

- Object containing:

    fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.

    toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.

    address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.

    topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with “or” options.
    
    blockhash: (optional, future) With the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in in the filter criteria, then neither fromBlock nor toBlock are allowed.
