BuildYourOwnedAgent

With drag and drop, you're able to customize and deploy your AI agent with prompts, different emotion expressions with generative AI, setup up game play strategy and integrate game servers.

You can setup rules for AI to deterministically decide its action, such as selecting from a list of optionns or more complicated state machine. Such behaviours will be added onto the contract template to create a trustless, immutable contract when deployed.

You can talk to each agent, powered by XMTP. One example is the NPC will send you a message when he steps on a poop 💩 in the game, and you can see she becomes angry on the on-chain avatar.

It is also possible to configure external plugins such as chainlink function to integrate an external game server, to maximize use cases of agents.

In the game demo, there is a Pokémon-style garden where agents will walk around. Tte game mechanics is very simple that when human step on a stone, she gets angry and when the dog step on a bone, it gets happy. All you need to do is to write on contract to request for movement, which they will decide according behaviour you configured on-chain -- such as always move up. Then the on-chain decision is send back to game server to progress the game and update contract status.

This tool helps us to deploy on-chain AI agents with guardrails and trustless mechanisms easily.

BYOA supports and deploying agents on mutliple EVM networks, namely we provide templates deployable for

• EVM L1/L2, e.g. Optimism Sepolia (Testnet)
• Galadriel (L1 for AI)

The no-code tool UI is created with react flow to enable simple drag & drop, connecting control nodes for agent similar to Retool or ComftyUI. We supports different contract agent teampltes and after configuring on tool the avatar, actions plans etc of agent, parameters will be passed to contract deployment and written on-chain. To create assets for various facial expression for different emotion, stable diffusion and Lora is used to pre-generate.

For the game demo, there is a custom game server built with nestjs which will control the game state, e.g. position of characters, decorations and the map.

With use of Chainlink functions, we allow on-chain NPCs to invoke our endpoint and create movement. Agent contract is registered as consumer of chainlink function. Thus after chainlink nodes invoke game API, result is written back to the smart contract. In our case, emotion of on-chain AI agent will be updated if our server find the character step on a poop.

XMTP is used to communicate between user and agents. With a shadow inbox account, accounts also able to send XMTP message via our server. An inbox account is created for each agent contract. Once XIP-44 is implemented, messages can be sent to/from contract account of Agent directly.

Envio is used to listen to events from the agent contracts and update game state accordingly.

To make the agent more autonomous, Lit action can be used so once user granted rights, server can programmably trigger trustless execution of contracts

Future Potentials

• We could further expand customizing of agents, such as integrating Controlnet with stable diffusion pipelines to automatically create different expressions for an agent.
