EOSIO - How to use Smart Contracts

[gartoxmx]

EOSIO Basic Operations

If you are a developer trying to run the [Getting Started with Smart Contracts] (https://developers.eos.io/eosio-cpp/docs/introduction-to-smart-contracts) you can follow the next tutorial using a docker image:

1. Get the docker image from repository using the next command:

     $ docker pull eosio/eos-dev
   

1. Start the EOSIO node.

     $ sudo docker run --rm --name eosio -d -p 8888:8888 -p 9876:9876 -v /tmp/work:/work -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev  /bin/bash -c "nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::wallet_plugin --plugin eosio::producer_plugin --plugin eosio::history_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:8888 --access-control-allow-origin=* --contracts-console"
   
   

1. Start the keosd service (is needed for can create the wallets and the accounts)

      $ docker exec eosio keosd --http-server-address=localhost:8899
   

1. Open a new tab or a new terminal window and set the alias for can use cleos

      $ alias cleos='docker exec eosio /opt/eosio/bin/cleos --wallet-url http://localhost:8899'
   

1. Create a new wallet on EOSIO using the next command ( by default use the name default )

      $ cleos wallet create
   

1. Import a new Key into the wallet

      $ cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
      - [ OUTPUT ] -
      imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
   

1. Load the BIOS contract using the eosio account (eosio account is the default account available on EOSIO image)

     $ cleos set contract eosio contracts/eosio.bios -p eosio@active
   

Creating a new account

1. First create a key

     $ cleos create key
     - [ OUTPUT ] -
      Private key: 5Jmsawgsp1tQ3GD6JyGCwy1dcvqKZgX6ugMVMdjirx85iv5VyPR
      Public key: EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4
     
   

2. Then import this key into our wallet

    $ cleos wallet import 5Jmsawgsp1tQ3GD6JyGCwy1dcvqKZgX6ugMVMdjirx85iv5VyPR
     - [ OUTPUT ] -    
      imported private key for: EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4
   

3. Create an account called user

     $ cleos create account eosio user EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4 EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4
   

4. Create an account called tester

     $ cleos create account eosio tester EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4 EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4
   

TESTING EOSIO TOKEN CONTRACT

Creating a new account

1. First create one new account

     $ cleos create account eosio eosio.token \
      EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4 \
      EOS7ijWCBmoXBi3CgtK7DJxentZZeTkeUnaSDvyro9dq7Sd1C3dC4
   

1. Deploy the eosio.token smart contract

     $ cleos set contract eosio.token /contracts/eosio.token -p eosio.token@active
   

1. Call to the method create of eosio.token Smart Contract

     $ cleos push action eosio.token create '[ "eosio", "1000000000.0000 SYS"]' \
       -p eosio.token@active
   

   or try the next for verbose mode

  ```bash
    $ cleos push action eosio.token create \
    '{"issuer":"eosio", "maximum_supply":"1000000000.0000 SYS"}' \
    -p eosio.token@active
  ``

1. Issue Tokens to Account "User"

     cleos push action eosio.token issue '[ "user", "100.0000 SYS", "memo" ]' \
      -p eosio@active
   

1. Transfer Tokens to Account "Tester"

     $ cleos push action eosio.token transfer \
      '[ "user", "tester", "25.0000 SYS", "m" ]' -p user@active
   

All the above instructions allow you use and understand the creation of keys, how to create accounts and how to deploy a smart contract, using the docker image.

Let me know any issue you have.

I think there are some things that could go into the article. Maybe do a spanish version, and also add some of the returns from the command line when inserting the contracts.

I get that as output when inserting the bios contracts. Great article thought.
