- Give your wallet a command!
- “Swap my $SHIBA tokens for Ether”
- “Claim my Gnosis airdrop”
Withdraw

Here’s
your TX

What’s the problem?
Even if wallets had a better user experience,
Ethereum would be still notoriously hard to use
- So many different user interfaces
- Scams, human errors, bad UX

privacy friendly
just use the dApp

How does it work?
Fine-tuned large language model (LLM)
- Knows about your account and
your on-chain past
- Creates transactions that can be
sent to MetaMask
- Transactions are simulated first, then

You are a system, that helps the user create Ethereum transactions from commands they
give to you. You will receive a user command and reply with a JSON object for a
transaction.
You will also receive some context, such as the users wallet address and addresses he
has interacted with in the past. If the user tries to interact with a new address,
you should warn him. If you need further information , like the target address, you
can ask the user for it.
Provide the response object in the following format:
```json
{
"from": "0x8d371a2379b4c27d567c998ee8d777ed1b92f4a7",
"to": "0xb2ecfe4e4d61f8790bbb9de2d1259b9e2410cea5",
"value": "1671886250000000",
"input": "0x",
}

Swap 1 ETH to DAI
Sure, I can create a
transaction that swaps
1 ETH for DAI for you.
Do you want to use
Uniswap?
Uh, I don’t care,
just swap it
Okay, you have used
Uniswap in the past.
I will use it for exchanging
your funds.
Here is the transaction:
(JSON)
15

16. HIΞRO
Send 100 ETH to
0xabc Please note that you have never
interacted with 0xabc before.
Are you sure you want to make
this transaction?
I think so… can
you make some
checks?
100 ETH is 91% of your ETH
balance.
The target address is a
fresh address and has
never received or sent any
transactions.
Do you maybe have a
typo?

Buy me a NewApe
Of course, I can do that
for you. However, please
note that the project
really looks like a scam.
Are you sure you want
to buy a NewApe NFT?
Darn, thanks
Can I assist you with
anything else?

How to build your own
- Create ~ 10k examples or more
- prompt -> response
- Use Chat GPT or a similar service to help you
- Fine tune a capable LLM, e.g. llama-2-70b, LoRa
- Cost: 100-5000$
- Optional: integrate LangChain or similar
- Host the LLM
- Locally (24 Gb RAM)
- Cloud (huggingface, replica, etc…)
- Connect to a UI

Imagine being able to simply chat with your digital wallet, telling it to "swap some DAI for ETH" or "put my money in a
yield product". Sounds easy and convenient, right? That's what we're cooking up with Hiero, a tool that blends the
cutting edge of AI and blockchain tech. Our talk at DappCon will break down how we're taking this idea from a sci-fi
concept to reality.We're training an AI, a large language model (LLM) to be precise, on understanding Ethereum and
all its quirks. Now, instead of navigating complex transaction paths yourself, you just need to tell the AI what you want
to do. It does all the heavy lifting, simulating your transaction on a fork before coming back to you with results. If
you're happy with the outcome, you execute the transaction, for example with MetaMask.Our talk won't just stop at
sharing our journey. We'll show you how you can train an LLM on Ethereum too. Beyond that, we’ll share how you can
integrate an LLM into your tools to create an expert system for your own transaction needs.So, join us for a chat - not
with an AI, but about an AI that could redefine how we manage transactions on Ethereum. We're excited to share
Hiero with you. Let's explore this new frontier together at DappCon!
