I have a running geth node and by using geth account new command I created a new account:

$ geth account list

Account #0: {47978a69f410d0f...} ...

Nevertheless, when using json rpc call to list my ether accounts a null result is obtained:

$ curl -X POST --data

'{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":1}' http://127.0.0.1:8545

{"jsonrpc":"2.0","id":1,"result":[]}

Why is that? Any hint? Thanks in advance!

I launched geth with the following command:

$geth --rpc --rpcapi "db,eth,net,web3" --rpcport "8545" --testnet 
--etherbase "0x47978a6...."

Is it possible that geth working on testnet gets confused on json rpc calls? Do I need to specify somehow in these calls to use testnet and not mainnet?

  • Try id:0 or remove id param.

  • Same result and error...: $ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":0}' http://127.0.0.1:8545 {"jsonrpc":"2.0","id":0,"result":[]} $ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[]}' http://127.0.0.1:8545 {"jsonrpc":"2.0","error":{"code":-32700,"message":"missing request id"}}´

  • What is id by the way? The id of what?

    eth.accounts[] is the index of the wallets that you are querying, in your case 0, the coinbase.

You don't need to use the params field in your call. By doing this, you are executing this command: eth.accounts[] which returns a null value. If you want to get a list of all the accounts, you should be executing eth.accounts. So, your RPC command should be:

curl -X POST -d '{"method":"eth_accounts","id":1}' 127.0.0.1:8545

P.S: I'm assuming you already enabled RPC on port 8545. Through the console, you can use admin.startRPC() to start RPC.

  • Thanks for the simplification, but unfortunatelly, same result: {"jsonrpc":"2.0","id":1,"result":[]}

  • Yes, it responds correctly to other commands: $ curl -X POST --data '{"jsonrpc":"2.0","method":"web3_sha3","params":["0x68656c6c6f20776f726c64"],"id":64}' localhost:8545 {"jsonrpc":"2.0","id":64,"result":"0x47173285a8d7341e5e972fc677286384f802f8ef42a5ec5f03bbfa254cb01fad"}

  • Maybe problem is related to geth using testnet and json rpc using mainnet... is that possible?

Enable the web3 RPC API when starting geth:

geth --rpc --rpcapi "web3" --rpcport "8545"

or if you want all APIs run:

geth --rpc --rpcapi "db,eth,net,web3" --rpcport "8545"

  • I just did it, but exactly the same result, geth account list shows the account but jsonrpc doesn't :-(

  • Problem is not API not responding, but responding null result. In fact, it responds correctly to other commands such as: $ curl -X POST --data '{"jsonrpc":"2.0","method":"web3_sha3","params":["0x68656c6c6f20776f726c64"],"id":64}' localhost:8545 {"jsonrpc":"2.0","id":64,"result":"0x47173285a8d7341e5e972fc677286384f802f8ef42a5ec5f03bbfa254cb01fad"}

  • It's likely that you are not sending the correct JSON object. Use web3 and call the same function: github.com/ethereum/wiki/wiki/JavaScript-API#web3ethaccounts as the curl parameters are correct (as suggested in the documentation).

Definitely the problem is related to node running on testnet and account being valid only on mainnet.

I created a new account on testnet and json-rpc query worked perfectly:

$geth --testnet account list

$geth --testnet account new Address: {3b877e80b5c0...}

$geth --testnet account list Account #0: {3b877e80b5c0...

$ curl -X POST -d '{"method":"eth_accounts","id":0}' 127.0.0.1:8545 {"jsonrpc":"2.0","id":0,"result":["0x3b877e80...

Thanks for your help!

  • In the original post the creation of the account does not have a --testnet command line option, so maybe that's the case. Did the OP trying to find the account on the mainnet?
