# 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.

The address to sign with must be unlocked.

# Parameters

  • Account Address

  • Message to sign

Copy // Request curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x3b7252d007059ffc82d16d022da3cbf9992d2f70", "0xdeadbeaf"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":"0x909809c76ed2a5d38733de39207d0f411222b9b49c64a192bf649cb13f63f37b45acb4f6939facb4f1c277bc70fb00407564140c0f18600ac44388f2c1dfd1dc1b"}

# 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 (opens new window), 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.

Sets the gas limit the miner will target when mining. Note: on networks where EIP-1559 (opens new window) 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.

Unsupported. This endpoint always returns false

# Parameters

  • Hex gas limit
Copy // Request curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasLimit","params":["0x10000"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":false}
