| personal Namespace | Documentation for the JSON-RPC API "personal" namespace |
The JSON-RPC API's personal namespace has historically been used to manage accounts and sign transactions and data over RPC. However, it has now been deprecated in favour of using Clef as an external signer and account manager. One of the major changes is moving away from indiscriminate locking and unlocking of accounts and instead using Clef to explicitly approve or deny specific actions. The first section on this page shows the suggested replacement for each method in personal. The second section shows the deprecated methods for archival purposes.
Method replacements
The following list shows each method from the personal namespace and the intended method in Clef that supercedes it.
personal_listAccounts
personal_listAccounts displays the addresses of all accounts in the keystore. It is identical to eth.accounts. Calling eth.accounts requires manual approval in Clef (unless a rule for it has been attested). There is also Clef's list-accounts command that can be called from the terminal.
Examples:
# eth_accounts using curl
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":1}'
// eth_accounts in Geth's JS console
eth.accounts;
# clef list-accounts in the terminal
clef list-accounts
personal_deriveAccount
personal_deriveAccount requests a hardware wallet to derive a new account, optionally pinning it for later use. This method is identical to clef_deriveAccount. The Clef method is not externally exposed so it must be called via a UI.
personal.ecRecover
personal_ecRecover returns the address for the account that was used to create a signature. An equivalent method, account_ecRecover is available on the Clef external API.
Example call:
curl --data '{"id": 4, "jsonrpc": "2.0", "method": "account_ecRecover","params": ["0xaabbccdd", "0x5b6693f153b48ec1c706ba4169960386dbaa6903e249cc79a8e6ddc434451d417e1e57327872c7f538beeb323c300afa9999a3d4a5de6caf3be0d5ef832b67ef1c"]}' -X POST localhost:8550
personal_importRawKey
personal.importRawKey was used to create a new account in the keystore from a raw private key. Clef has an equivalent method that can be invoked in the terminal using:
clef importraw <private-key-as-hex-string>
personal_listWallets
As opposed to listAccounts, this method lists full details, including usb path or keystore-file paths. The equivalent method is clef_listWallets. This method can be called from the terminal using:
clef list-wallets
personal_newAccount
personal_newAccount was used to create a new accoutn and save it in the keystore. Clef has an equivalent method, account_new. It can be accessed on the terminal using an http request or using a Clef command:
Example call (curl):
curl --data '{"id": 1, "jsonrpc": "2.0", "method": "account_new", "params": []}' -X POST localhost:8550
Example call (Clef command):
clef newaccount
Both require manual approval in Clef unless a custom ruleset is in place.
personal_openWallet
personal_OpenWallet initiates a hardware wallet opening procedure by establishing a USB connection and then attempting to authenticate via the provided passphrase. Note, the method may return an extra challenge requiring a second open (e.g. the Trezor PIN matrix challenge). personal_openWallet is identical to clef_openWallet. The Clef method is not externally eposed, meaning it must be called via a UI.
personal_sendTransaction
personal_sendTransaction ws used to sign and submit a transaction. This can be done using eth_sendTransaction, requiring manual approval in Clef.
Example call (Javascript console):
// this command requires 2x approval in Clef because it loads account data via eth.accounts[0]
// and eth.accounts[1]
var tx = { from: eth.accounts[0], to: eth.accounts[1], value: web3.toWei(0.1, 'ether') };
// then send the transaction
eth.sendTransaction(tx);
Example call (terminal)
curl --data '{"id":1,"jsonrpc":"2.0", "method":"eth_sendTransaction","params":[{"from": "0xE70CAD05D0D54Ae3C9Fe5442f901E0433f9bd14B", "to":"0x4FDc03d09Ffca5Bba3138149E29D85C8A9E2Ac42", "gas":"21000","gasPrice":"20000000000", "nonce":"94"}]}' -H "Content-Type: application/json" -X POST localhost:8545
personal_sign
The sign method calculates an Ethereum specific signature with sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message)). 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.
personal.sign is equivalent to Clef's account_signData. It returns the calculated signature.
Example call:
curl --data {"id": 3, "jsonrpc": "2.0", "method": "account_signData", "params": ["data/plain", "0x1923f626bb8dc025849e00f99c25fe2b2f7fb0db","0xaabbccdd"]} -X POST localhost:8550
Clef also has account_signTypedData that signs data structured according to EIP-712 and returns the signature.
Example call (use the following as a template for <data> in curl --data <data> -X POST localhost:8550 -H "Content-Type: application/json")
{
"id": 68,
"jsonrpc": "2.0",
"method": "account_signTypedData",

"wallet": "0xbBbBBBBbbBBBbbbBbbBbbbbBBbBbbbbBbBbbBBbB"
},
"contents": "Hello, Bob!"
}
}
]
}
personal_signTransaction
personal_signTransaction was used to create and sign a transaction from the given arguments. The transaction was returned in RLP-form, not broadcast to other nodes. The equivalent method is Clef's account_signTransaction from the external API. The arguments are a transaction object ({"from": , "to": , "gas": , "maxPriorityFeePerGas": , "MaxFeePerGas": , "value": , "data": , "nonce": })) and an optional method signature that enables Clef to decode the calldata and show the user the methods, arguments and values being sent.
Example call (terminal):
curl --data '{"id": 2, "jsonrpc": "2.0", "method": "account_signTransaction", "params": [{"from": "0x1923f626bb8dc025849e00f99c25fe2b2f7fb0db", "gas": "0x55555","gasPrice": "0x1234", "input": "0xabcd", "nonce": "0x0", "to": "0x07a565b7ed7d7a678680a4c162885bedbb695fe0", "value": "0x1234"}]}' -X POST -H "Content-Type: application/json" localhost:8550
Methods without replacements
Thjere are a few methods that were available in the personal namepsace that have been deprecated without replacements. These are:
personal_unlockAccount
There is no need for a direct replacement for personal_unlockAccount. Using Clef to manually approve actions or to attest custom rulesets is a much more secure way to interact with accounts without needing to indiscriminately unlock accounts.
personal_lockAccount
There is no need for a direct replacement for personal_lockAccount because account locking/unlocking is replaced by Clef's approve/deny logic. This is a more secure way to interact with accounts.
personal.unpair
Unpair deletes a pairing between some specific types of smartcard wallet and Geth. There is not yet an equivalent method in Clef.
personal_initializeWallet
InitializeWallet is for initializing some specific types of smartcard wallet at a provided URL. There is not yet a corresponding method in Clef.
Deprecated method documentation
The personal API managed private keys in the key store. It is now deprecated in favour of using Clef for interacting with accounts. The following documentation should be treated as archive information and users should migrate to using Clef for account interactions.

| RPC | {"method": "personal_openWallet", "params": [string, string]} |
personal_unlockAccount
Decrypts the key with the given address from the key store.
Both passphrase and unlock duration are optional when using the JavaScript console. If the passphrase is not supplied as an argument, the console will prompt for the passphrase interactively. The unencrypted key will be held in memory until the unlock duration expires. If the unlock duration defaults to 300 seconds. An explicit duration of zero seconds unlocks the key until geth exits.
The account can be used with eth_sign and eth_sendTransaction while it is unlocked.
| Client | Method invocation |
|---|---|
| Console | personal.unlockAccount(address, passphrase, duration) |
| RPC | {"method": "personal_unlockAccount", "params": [string, string, number]} |

Supplying the passphrase and unlock duration as arguments:
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120", "foo", 30)
true
To type in the passphrase and still override the default unlock duration, pass null as the passphrase.
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120", null, 30)

| RPC | {"method": "personal_unpair", "params": [string, string]} |
personal_sendTransaction
Validate the given passphrase and submit transaction.
The transaction is the same argument as for eth_sendTransaction (i.e. transaction object) and contains the from address. If the passphrase can be used to decrypt the private key belogging to tx.from the transaction is verified, signed and send onto the network. The account is not unlocked globally in the node and cannot be used in other RPC calls.
| Client | Method invocation |
|---|---|
| Console | personal.sendTransaction(tx, passphrase) |
| RPC | {"method": "personal_sendTransaction", "params": [tx, string]} |
Examples

personal_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.
See ecRecover to verify the signature.
| Client | Method invocation |
|---|---|
| Console | personal.sign(message, account, [password]) |
| RPC | {"method": "personal_sign", "params": [message, account, password]} |
Examples
> personal.sign("0xdeadbeaf", "0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "")
"0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"
personal_signTransaction
SignTransaction will create a transaction from the given arguments and tries to sign it with the key associated with tx.from. If the given passwd isn't able to decrypt the key it fails. The transaction is returned in RLP-form, not broadcast to other nodes. The first argument is a transaction object and the second argument is the password, similar to personal_sendTransaction.
| Client | Method invocation |
|---|---|
| Console | personal.signTransaction(tx, passphrase) |
| RPC | {"method": "personal_signTransaction", "params": [tx, string]} |
personal_ecRecover
ecRecover returns the address associated with the private key that was used to calculate the signature in personal_sign.
| Client | Method invocation |
|---|---|
| Console | personal.ecRecover(message, signature) |
| RPC | {"method": "personal_ecRecover", "params": [message, signature]} |
Examples
> personal.sign("0xdeadbeaf", "0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "")
