Because GateChain EVM is basically compatible with Ethereum, much of the content in this document comes from the contribution of Ethereum EVM documents.

}

eth_getStorageAt

Returns the value from a storage position at a given address.

Parameters

• DATA, 20 Bytes - address of the storage.
• QUANTITY - integer of the position in the storage.
• QUANTITY|TAG - integer block number, or the string "latest", "earliest" or "pending"

Returns

DATA - the value at this storage position.

Example

Calculating the correct position depends on the storage to retrieve. Consider the following contract deployed at 0x391694e7e0b0cce554cb130d723a9d27458f9298 by address 0x295a70b2de5e3953354a6a8344e616ed314d7251.

contract Storage {
    uint pos0;
    mapping(address => uint) pos1;

    function Storage() {
        pos0 = 1234;
        pos1[msg.sender] = 5678;
    }
}

Retrieving the value of pos0 is straight forward:

// Request
curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' localhost:8545

// Result
{
  "jsonrpc":"2.0",
  "id":1,
  "result":"0x00000000000000000000000000000000000000000000000000000000000004d2"
}

Retrieving an element of the map is harder. The position of an element in the map is calculated with:

keccack(LeftPad32(key, 0), LeftPad32(map position, 0))

This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:

keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))

The geth console which comes with the web3 library can be used to make the calculation:

> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
undefined
> web3.sha3(key, {"encoding": "hex"})
"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"

Now to fetch the storage:

// Request
curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' localhost:8545

// Result
{
  "jsonrpc":"2.0",
  "id":1,
  "result":"0x000000000000000000000000000000000000000000000000000000000000162e"
}

}

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.

Note the address to sign with must be unlocked.

Parameters

• account, message
• DATA, 20 Bytes - address
• DATA, N Bytes - message to sign

Returns

DATA: Signature

Example

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "0xdeadbeaf"],"id":1}'

}

   • to: DATA, 20 Bytes - The address the transaction is directed to.
   • gas: QUANTITY - (optional) Integer of the gas provided for the transaction execution.

}

eth_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain.

Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

Parameters

See eth_call parameters, expect that all properties are optional. If no gas limit is specified geth uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to executed the call/transaction when the amount of gas is higher than the pending block gas limit.

Returns

QUANTITY - the amount of gas used.

Example

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{see above}],"id":1}'

• transactionIndex: QUANTITY - integer of the transactions index position in the block.
• blockHash: DATA, 32 Bytes - hash of the block where this transaction was in.
• blockNumber: QUANTITY - block number where this transaction was in.
• from: DATA, 20 Bytes - address of the sender.
• to: DATA, 20 Bytes - address of the receiver. null when its a contract creation transaction.
• cumulativeGasUsed: QUANTITY - The total amount of gas used when this transaction was executed in the block.
• gasUsed: QUANTITY - The amount of gas used by this specific transaction alone.
• contractAddress: DATA, 20 Bytes - The contract address created, if the transaction was a contract creation, otherwise null.
• logs: Array - Array of log objects, which this transaction generated.
• logsBloom: DATA, 256 Bytes - Bloom filter for light clients to quickly retrieve related logs.
