I have geth running on my server. I am building a php website which act as wallet. Now iam able to create addresses. I need to be able to deposit and withdraw ETH between addresses on same node. I start geth with below command.

go-ethereum/build/bin/geth console  --rpc --rpcapi="db,eth,net,web3,personal,web3" --rpccorsdomain "*" --syncmode "light"

How to acheive the functionality of a wallet on geth over rpc ? Is there a command or API call for that? Iam finding it hard to understand the documentation.

UPDATE: What I want to do is transfer ETH from one account to another. Below are the api calls i tried and the errors I got in the browser when i call transfer function in my php class. Can someone please correct me

{"jsonrpc":"2.0","id":1,"method":"personal_signAndSendTransaction","params":[[{"from":"0xb60e8dd61c5d32be8058bb8eb970870f07233155","to":"0xd46e8dd67c5d32be8058bb8eb970870f07244567","gas":"0x76c0","gasPrice":"0x9184e72a000","value":"0x9184e72a","data":"0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"}],"passphrase"]}

  • do not use eth_sendTransaction, you are going to have to unlock the account and that's insecure. Your users are going to be hacked and you are going to be hated. Ese eth_sendRawTransaction and sign transaction before sending it, with javascript . Your best example is myphpwallet, download the sources and just copy all the process of signing transaction and youre done

In Geth console, you can use the sendTransaction function :

web3.eth.sendTransaction({
    from: "0xE618A4B5A516f371Ce26d9A1DBE7839F4e3812GB",
    to: "0xE618A4B5A516f371Ce26d9A1DBE7839F4e3812CB",
    value: web3.toWei(1, "ether")
})

You can use eth_sendtransaction to send a transaction to the destination

In the params section 

params: [{
    "from": "0xb60e8dd61c5d32be8058bb8eb970870f07233155",
    "to": "0xd46e8dd67c5d32be8058bb8eb970870f07244567",
    "gas": "0x76c0", // 30400
    "gasPrice": "0x9184e72a000", // 10000000000000
    "value": "0x9184e72a", // 2441406250
    "data": "0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"
}]

You should get back a transaction signature

{
    "id":1,
    "jsonrpc": "2.0",
    "result": "0xe670ec64341771606e55d6b4ca35a1a6b75ee3d5145a99d05921026d1527331"
}

This works on accounts that have been unlocked in geth previously

  • You need to buy some Ether, send them to the account that is unlocked in the geth client and you should be able to send fractions of that Ether to other adresses.

  • What does "outside of your network" mean? How do you define your network? You can send Ether to any address. Even if the address does not exist.
