Service Providers

'Service Providers' are defined as entities that provide services for end-users that involve some form of interaction with the AIOZ Network. More specifically, this document is focused on interactions with tokens.

Service Providers are expected to act as trusted points of contact to the blockchain for their end-users. This Service Providers section does not apply to wallet builders that want to provide Light Client functionalities.

This document describes:

Connection Options

There are four main technologies to consider to connect to the AIOZ Network:

  • Full Nodes: Interact with the blockchain.
  • REST Server: Serves for HTTP calls.
  • REST API: Use available endpoints for the REST Server.
  • GRPC: Connect to the AIOZ Network using gRPC.

Running a Full Node

What is a Full Node?

A Full Node is a network node that syncs up with the state of the blockchain. It provides blockchain data to others by using RESTful APIs, a replica of the database by exposing data with interfaces. A Full Node keeps in syncs with the rest of the blockchain nodes and stores the state on disk. If the full node does not have the queried block on disk the full node can go find the blockchain where the queried data lives.

Installation and Configuration

This section describes the steps to run and interact with a full node for the AIOZ Network.

First, you need to install the software.

Consider running your own AIOZ Network Full Node.

Command-Line Interface

The command-line interface (CLI) is the most powerful tool to access the AIOZ Network and use aioz. To use the CLI, you must install the latest version of aioz on your machine.

Compare your version with the latest release version

aiozd version --long

Use "aiozd query [command] --help" for more information about a command.

Remote Access to aiozd

When choosing to remote access a Full Node and aiozd, you need a Full Node running and aioz installed on your local machine.

aiozd is the tool that enables you to interact with the node that runs on the AIOZ Network, whether you run it yourself or not.

To set up aiozd on a local machine and connect to an existing full node, use the following command:

aiozd config <flag> <value>

First, set up the address of the full node you want to connect to:

aiozd config node <host>:<port
 
// example: aiozd config node https://rpc-dataseed.aioz.network:443

If you run your own full node locally, use tcp://localhost:26657 as the address.

Set the default value of the --trust-node flag:

aiozd config trust-node false
 
// Set to true if you run a light client node

Finally, set the chain-id of the blockchain you want to interact with:

aiozd config chain-id aioz_168-1

Next, learn to use CLI commands to interact with the full node. You can run these commands as remote control or when you are running it on your local machine.

Create a Key Pair

The default key is ethsecp256k1 elliptic curve. Use the aiozd keys command to list the keys and generate a new key.

aiozd keys add <your_key_name>

You will be asked to create a password (at least 8 characters) for this key-pair. This will return the information listed below:

  • NAME: Name of your key
  • TYPE: Type of your key, always local.
  • ADDRESS: Your address. Used to receive funds.
  • ADDRESS_HEX: Your address in hex format. Used to receive funds.
  • PUBKEY: Your public key. Useful for validators.
  • MNEMONIC: 24-word phrase. Save this mnemonic somewhere safe. This phrase is required to recover your private key in case you forget the password. The mnemonic is displayed at the end of the output.

You can see all available keys by typing:

aiozd keys list

Use the --recover flag to add a key that imports a mnemonic to your keyring.

aiozd keys add <your_key_name> --recover

Check your Account

You can view your account by using the query account command.

aiozd query account <YOUR_ADDRESS>

It will display your account type, account number, public key and current account sequence.

'@type': /ethermint.types.v1.EthAccount
account_number: "xxxx"
address: aioz____
pub_key:
  '@type': /ethermint.crypto.v1.ethsecp256k1.PubKey
  key: xxx
sequence: "x"

Check your Balance

Query the account balance with the command:

aiozd query bank balances <YOUR_ADDRESS>

The response contains keys balances and pagination. Each balances entry contains an amount held, connected to a denom identifier. The typical $AIOZ token is identified by the denom attoaioz. Where 1 attoaioz is 0.000000000000000001 AIOZ.

balances: 
- amount: "12345678"
  denom: attoaioz
pagination:
  next_key: null
  total: "0"

When you query an account that has not received any token yet, the balances entry is shown as an empty array.

balances: []
pagination:
  next_key: null
  total: "0"

Send Coins Using the CLI

To send coins using the CLI:

aiozd tx send <from_key_or_address> <to_address> <amount> \
    --chain-id=<your_chain_id> 

Parameters:

  • <from_key_or_address>: Key name or address of sending account.
  • <to_address>: Address of the recipient.
  • <amount>: This parameter accepts the format <value|coinName>, such as 1000000000attoaioz.

Flags:

  • --chain-id: This flag allows you to specify the id of the chain. There are different ids for different testnet chains and mainnet chains.
  • --gas-prices: This flag allows you to specify the gas prices you pay for the transaction. The format is used as 1000000000attoaioz

REST API

The REST API documents (opens in a new tab) list all the available endpoints that you can use to interact with your full node. Learn how to enable the REST API on your full node.

Listen for Incoming Transactions

The recommended way to listen for incoming transactions is to periodically query the blockchain by using the following HTTP endpoint:

/cosmos/bank/v1beta1/balances/{address} (opens in a new tab)
