### `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 recognizable 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.
:::

- 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](https://eips.ethereum.org/EIPS/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.

## WebSocket Methods

Read about websockets in [events](./events.md)

### `eth_subscribe`

subscribe using JSON-RPC notifications. This allows clients to wait for events instead of polling for them.

```

### `eth_unsubscribe`

Unsubscribe from an event using the subscription id

#### Parameters

- Subscription ID

```json
// Request
{"id": 1, "method": "eth_unsubscribe", "params": ["0x34da6f29e3e953af4d0c7c58658fd525"]}

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

## Debug Methods

### `debug_traceTransaction`

The `traceTransaction` debugging method will attempt to run the transaction in the exact same manner as it was executed on the network. It will replay any transaction that may have been executed prior to this one before it will finally attempt to execute the transaction that corresponds to the given hash.

#### Parameters

- Trace Config

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"debug_traceTransaction","params":["0xddecdb13226339681372b44e01df0fbc0f446fca6f834b2de5ecb1e569022ec8", {"tracer": "{data: [], fault: function(log) {}, step: function(log) { if(log.op.toString() == \"CALL\") this.data.push(log.stack.peek(0)); }, result: function() { return this.data; }}"}],"id":1}' -H "Content-Type: application/json" http://localhost:8545

//Result
["68410", "51470"]
```


## Miner Methods

### `miner_getHashrate`

::: tip
**Private**: Requires authentication.
:::

Get the hashrate in H/s (Hash operations per second).

::: warning
Proof-of-Work specific. This endpoint always returns `0`.
:::

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

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

### `miner_setExtra`

::: tip
**Private**: Requires authentication.
:::

Sets the extra data a validator can include when proposing blocks. This is capped at 32 bytes.

::: warning
Unsupported. This endpoint always returns an error
:::

#### Parameters

- Data

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

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

### `miner_setGasPrice`

::: tip
**Private**: Requires authentication.
:::

Sets the minimal gas price used to accept transactions. Any transaction below this limit is excluded from the validator block proposal process.

This method requires a `node` restart after being called because it changes the configuration file.

Make sure your `ethermintd start` call is not using the flag `minimum-gas-prices` because this value will be used instead of the one set on the configuration file.

#### Parameters

- Hex Gas Price

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasPrice","params":["0x0"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

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

### `miner_start`

::: tip
**Private**: Requires authentication.
:::

Start the CPU validation process with the given number of threads.

::: warning
Unsupported. This endpoint always returns an error
:::

#### Parameters

- Hex Number of threads

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_start","params":["0x1"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

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

### `miner_stop`

::: tip
**Private**: Requires authentication.
:::

Stop the validation operation.

::: warning
Unsupported. This endpoint always performs a no-op.
:::

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

### `miner_setGasLimit`

::: tip
**Private**: Requires authentication.
:::

Sets the gas limit the miner will target when mining. Note: on networks where [EIP-1559](https://eips.ethereum.org/EIPS/eip-1559) is activated, this should be set to twice what you want the gas target (i.e. the effective gas used on average per block) to be.

::: warning
Unsupported. This endpoint always returns `false`
:::

#### Parameters

- Hex gas limit

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_start","params":["0x10000"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

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

#### Parameters

- Hex Number of threads

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_start","params":["0x1"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

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

### `miner_setEtherbase`

::: tip
**Private**: Requires authentication.
:::

Sets the etherbase. It changes the wallet where the validator rewards will be deposited.

#### Parameters

- Account Address

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

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

## TxPool Methods

### `txpool_content`

Returns a list of the exact details of all the transactions currently pending for inclusion in the next block(s), as well as the ones that are being scheduled for future execution only.

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

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

### `txpool_inspect`

Returns a list on text format to summarize all the transactions currently pending for inclusion in the next block(s), as well as the ones that are being scheduled for future execution only. This is a method specifically tailored to developers to quickly see the transactions in the pool and find any potential issues.

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

// Result

```

### `txpool_status`

Returns the number of transactions currently pending for inclusion in the next block(s), as well as the ones that are being scheduled for future execution only.

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

// Result
