For each event that matches the subscription a notification with relevant data is send together with the subscription id. #### Parameters - Subscription Name - Optional Arguments ```json // Request {"id": 1, "method": "eth_subscribe", "params": ["newHeads", {"includeTransactions": true}]} // Result < {"jsonrpc":"2.0","result":"0x34da6f29e3e953af4d0c7c58658fd525","id":1} ``` ### eth_unsubscribe Unsubscribe from an event using the subscription id #### Parameters - Subscription ID ```json // Request {"id": 1, "method": "eth_unsubscribe", "params": ["0x34da6f29e3e953af4d0c7c58658fd525"]} // Result {"jsonrpc":"2.0","result":true,"id":1} ``` ## Personal Methods ### personal_importRawKey Imports the given unencrypted private key (hex string) into the key store, encrypting it with the passphrase.

The account can no longer be used to send transactions. #### Parameters - Account Address ```json // Request curl -X POST --data '{"jsonrpc":"2.0","method":"personal_lockAccount","params":["0x0f54f47bf9b8e317b214ccd6a7c3e38b893cd7f0"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":true} ``` ### personal_newAccount Generates a new private key and stores it in the key store directory. The key file is encrypted with the given passphrase. Returns the address of the new account. #### Parameters - Passphrase ```json // Request curl -X POST --data '{"jsonrpc":"2.0","method":"personal_newAccount","params":["This is the passphrase"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":"0xf0e4086ad1c6aab5d42161d5baaae2f9ad0571c0"} ``` ### 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. 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. #### Parameters - Account Address - Passphrase - Duration ```json // Request curl -X POST --data '{"jsonrpc":"2.0","method":"personal_unlockAccount","params":["0x0f54f47bf9b8e317b214ccd6a7c3e38b893cd7f0", "secret passphrase", 30],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":true} ``` ### personal_sendTransaction Validate the given passphrase and submit transaction. The transaction is the same argument as for eth_sendTransaction 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. :::warning The account is not unlocked globally in the node and cannot be used in other RPC calls. ::: #### Parameters - Object containing: from: DATA, 20 Bytes - The address the transaction is send from. to: DATA, 20 Bytes - (optional when creating new contract) The address the transaction is directed to. value: QUANTITY - value sent with this transaction - Passphrase ```json // Request curl -X POST --data '{"jsonrpc":"2.0","method":"personal_sendTransaction","params":[{"from":"0x3b7252d007059ffc82d16d022da3cbf9992d2f70","to":"0xddd64b4712f7c8f1ace3c145c950339eddaf221d", "value":"0x16345785d8a0000"}, "passphrase"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":"0xd2a31ec1b89615c8d1f4d08fe4e4182efa4a9c0d5758ace6676f485ea60e154c"} ``` ### personal_sign The sign method calculates an Ethereum specific signature with: sign(keccack256("\x19Ethereum Signed Message:\n" + len(message) + message))). #### Parameters - Message - Account Address - Password ```json // Request curl -X POST --data '{"jsonrpc":"2.0","method":"personal_sign","params":["0xdeadbeaf", "0x3b7252d007059ffc82d16d022da3cbf9992d2f70", "password"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":"0xf9ff74c86aefeb5f6019d77280bbb44fb695b4d45cfe97e6eed7acd62905f4a85034d5c68ed25a2e7a8eeb9baf1b8401e4f865d92ec48c1763bf649e354d900b1c"} ``` ### personal_ecRecover ecRecover returns the address associated with the private key that was used to calculate the signature in personal_sign. #### Parameters - Message - Signature returned from personal_sign ```json // Request curl -X POST --data '{"jsonrpc":"2.0","method":"personal_ecRecover","params":["0xdeadbeaf", "0xf9ff74c86aefeb5f6019d77280bbb44fb695b4d45cfe97e6eed7acd62905f4a85034d5c68ed25a2e7a8eeb9baf1b8401e4f865d92ec48c1763bf649e354d900b1c"],"id":1}' -H "Content-Type: application/json" http://localhost:8545 // Result {"jsonrpc":"2.0","id":1,"result":"0x3b7252d007059ffc82d16d022da3cbf9992d2f70"} ``` ## Next {hide} Learn about the [encoding](./../core/encoding.md) formats used on Ethermint {hide}
