# @polkadot/signer-cli A simple CLI interface for offline signing. This can also be executed via the [docker image](../../README.md#docker). ## Create a transaction To create a transaction, you need to use the API to connect to a chain, enabling the creation of a transaction using the chain's metadata. In a terminal, run the `submit` command with the following form: `yarn run:signer submit --account <ss58> --ws <endpoint> <module.method> [param1] [...] [paramX]` For instance, to make a transfer, we run the following command: `yarn run:signer submit --account 5HNHXTw65dTNVGRdYkxFUpKcvmUYQMZHcDHmSKpuC8pvVEaN --ws wss://poc3-rpc.polkadot.io/ balances.transfer 5DkQbYAExs3M2sZgT1Ec3mKfZnAQCL4Dt9beTCknkCUn5jzo 123` On execution, it will prompt us with: ``` Payload: 0x040300ff4a83f1...a8239139ff3ff7c3f6 Signature> ``` The `Payload` is the hex that needs to be signed. Pasting the hex signature (followed by `Enter`) submits it to the chain. You can also use this command to submit pre-signed transactions, e.g. generated using the `sendOffline` command (see below). The syntax is as follows: `yarn run:signer submit --tx <signedTransaction> --ws <endpoint>` ## Sign a transaction To sign, you do not need a network connection at all and this command does not use the API to make connections to a chain. In a terminal, run the `sign` command with the following form: `yarn run:signer sign --account <ss58> --seed <suri> --type <ed25519|sr25519> <hex payload>` For instance, to sign the transfer made above, we run: `yarn run:signer sign --account 5HNHXTw65dTNVGRdYkxFUpKcvmUYQMZHcDHmSKpuC8pvVEaN --seed "leaf ... rude" --type sr25519 0x040300ff4a83f1...a8239139ff3ff7c3f6` On execution, it will respond with: ``` Signature: 0xe6facf194a8e...413ce3155c2d1240b ``` Paste this signature into the submission in the first terminal, and off we go. By default, `submit` will create a mortal extrinsic with a lifetime of 50 blocks. Assuming a six-second block time, you will have five minutes to go offline, sign the transaction, paste the signature, and submit the signed transaction. ## Send offline This functionality lets you generate signed transactions for execution at a later time, on a different device or using other tools. It is intended to resemble MyEtherWallet's [`Send offline`](https://kb.myetherwallet.com/en/offline/offline_transaction/) feature. The flow is similar to the `submit` command. First, run the `sendOffline` command on a computer with a network connection: `yarn run:signer sendOffline --account 5HNHXTw65dTNVGRdYkxFUpKcvmUYQMZHcDHmSKpuC8pvVEaN --ws wss://poc3-rpc.polkadot.io/ balances.transfer 5DkQbYAExs3M2sZgT1Ec3mKfZnAQCL4Dt9beTCknkCUn5jzo 123` This will give you a payload to sign. Use the `sign` command as per instructions above. Once you've pasted the signature into the `sendOffline` terminal (and hit `Enter`), it will print the signed transaction that can be stored and submitted later (e.g. using the `submit` command). Run `yarn run:signer --help` to learn about optional parameters.
