Crypto Chat Bots

Crypto Chat Bots is a unique offering of our platform combining the advantages of conversational chat bots with smart contracts and distributed ledger technology.

Features

In essence, Crypto Chat Bots are automated entities possessing the following features:

• can send and receive chat messages
• can offer both conversational and button-based UI
• can send guidance messages visible for one or specific users only
• control one or more crypto wallets
• may have their own social profile
• can own and transfer crypto tokens (including ERC-20 Coins and NFT Items)
• may control chat rooms and/or interact with other features of Dappros Platform and Ethereum blockchain similarly as normal users do
• often have part or most of their logic managed by a smart contract

Crypto Chat Bots allow ecosystem Owners and Users to build their own interactions and effectively extend the platform building exciting mechanisms and social economy interactions for their users.

Architecture

As described in the network diagram above, Bots can be hosted at your own hosting of choice and they can interact with:

• chat rooms and chat messages via XMPP protocol

• smart contracts and blockchain via Web3

• Dappros Platform via REST JSON API

Developers can create their own chat bots in any programming language from scratch, but the easiest thing to do is use code samples offered in our Github repo.

The requisites for the programming language of your chat bot is that it has an XMPP library so you can interact with chat server messages.

In case your bot has a Smart Contract component, it would also need to have a Web3 library. There are well known Web3.js and Web3.py libraries which correspondingly allow you to write crypto enabled chat bots in Javascript-based languages (Node.js, Typescript) as well as in Python.

• Social
