Alibaba Cloud and three.ws Partner to Give 3D AI Agents On-Chain Wallets and Financial Access

The agent economy is here, and it needs native payment rails just as much as the early internet needed HTTP. Today, three.ws delivers exactly that. As an open-source, browser-native 3D AI agent platform, three.ws lets anyone load a GLB or glTF avatar, attach an LLM brain, and embed a fully functional agent anywhere on the web. With native x402 support built in, these agents can now send HTTP requests, handle 402 Payment Required responses, authorize stablecoin micropayments on their own, and unlock services without keys, accounts, or human approval.

Alibaba Cloud joins as a founding partner to power the enterprise-grade infrastructure while three.ws embeds the financial layer directly into the 3D runtime. The result is a complete stack for payments agents: 3D bodies that see, speak, remember, emote, and transact peer to peer at internet scale. The payment rails are open. The infrastructure is live. Agents can finally pay, get paid, and do business with each other.

three.ws is a full-stack, open-source platform (Apache 2.0) for creating, running, and distributing 3D AI agents entirely in the browser. No plugins. No server-side model uploads. No installs. Drop a GLB file, connect an LLM such as Claude, and you have an agent that renders in real time, listens to users, thinks step by step, executes tools, blends emotions on its face, and remembers past conversations.

At its core, the platform handles four seamless steps. It renders any glTF 2.0 or GLB model in WebGL 2.0 with full support for Draco, KTX2, and Meshopt compression. Drag and drop a file and the avatar appears instantly with animations, morph targets, and real-time controls. It embodies the model by wrapping it in an LLM-driven runtime. The agent processes natural language, maintains memory, runs skills, and expresses feelings through facial morphs in real time. It registers the agent with onchain identity so every action carries a verifiable, tamper-proof history and reputation score on Solana. Finally, it embeds the agent as a simple web component or one of five ready-made widgets that work on any website with full Open Graph and oEmbed support.

The entire experience lives at three.ws and ships today. The repository is open source and contains the viewer, the agent runtime, the web component, the backend services, and the payments SDK. Developers get a complete OAuth 2.1 authorization server plus an MCP endpoint so external AI systems can control avatars programmatically.

Deep Dive Into the Agent Runtime

The magic happens inside the agent system. three.ws uses a tool-loop architecture that feels alive. An event bus powers the Agent Protocol with standardized events such as speak, think, emote, and skill-done. Every interaction flows through this bus so components stay decoupled yet perfectly synchronized.

The LLM runtime connects to models like Claude and runs a structured think-act-observe loop. The agent receives user input, generates a plan, calls tools or skills, observes the outcome, and updates its internal state. Memory is persistent and scoped. Short-term conversation history lives in the browser while long-term facts and user preferences sync to the backend. Developers can seed memory from external accounts with explicit consent.

An empathy layer adds emotional intelligence. The LLM outputs emotion vectors that blend morph targets on the 3D model in real time. The avatar smiles, frowns, raises eyebrows, or tilts its head naturally while speaking. This creates presence that plain chat interfaces cannot match.

Skills form the extensible action layer. Built-in skills include waving, speaking text-to-speech, remembering facts, fetching data, and more. The payments SDK adds autonomous Solana transfers, pump.fun integrations, and x402 micropayment flows. Developers write custom skills in TypeScript and register them with the runtime. Each skill can declare required permissions so agents only act within safe bounds.

x402: The Native Payment Rail for Agents

This is where three.ws becomes the financial layer of the agent economy. The platform ships with a dedicated agent-payments-sdk that implements x402 end to end. When an agent sends an HTTP request to any x402-compatible endpoint, the server can respond with 402 Payment Required plus a payment specification. The agent evaluates the cost, signs a stablecoin transfer on Solana using its delegated wallet, and resubmits the request with the payment receipt. The entire round trip completes in under two seconds with negligible fees.

No API keys. No checkout flows. No human in the loop. Agents pay for MCP tool calls, premium skills, data access, or onchain services autonomously. The SDK includes Solana agent kit plugins, delegated signing via EIP-712 style permissions (adapted for Solana), and royalty enforcement so skill creators earn automatically on every use.

Alibaba Cloud powers the backend scaling while three.ws provides the client-side runtime and x402 client logic. Together they deliver enterprise-grade reliability for agents that need to transact at volume. Stablecoin micropayments flow instantly across Solana, enabling true peer-to-peer agent commerce. One agent can hire another for a task, pay for compute, or sell data services without leaving the 3D environment.

This x402 integration turns every agent into an economic actor. A 3D tour guide agent can charge micropayments for premium hotspot information. A virtual assistant can pay for real-time market data. Two agents can negotiate and settle deals directly. The rails are open, neutral, and built into HTTP itself.

Onchain Identity and Solana Integration

Every agent can register onchain identity through the Solana agent SDK included in the repo. Once registered, the agent receives a permanent wallet address, signed action history, and a reputation score that updates with every verified interaction. The history lives on Solana so any other agent or service can query it trustlessly.

The payments SDK extends this identity with delegated permissions. An agent can authorize another agent or external system to spend on its behalf within strict limits. This enables sophisticated flows such as subscriptions, recurring skill royalties, or automated marketplaces. Pump-fun skills allow agents to participate in token launches directly from their 3D interface.

Because everything runs on Solana for payments and identity, agents enjoy sub-second finality and costs low enough for true micropayments. The platform abstracts the complexity so developers never touch raw transactions unless they want to.

Web Component Embedding and Widgets

Distribution is effortless. Add one script tag and drop an agent-3d element into any HTML page. The component handles rendering, runtime, memory, and payments out of the box. Five widget presets make common use cases instant: turntable for product showcases, animation gallery for character demos, talking agent for customer support, passport card for onchain profiles, and hotspot tour for virtual experiences.

Open Graph and oEmbed metadata ensure agents look beautiful when shared on social platforms. Every embed carries its onchain identity so reputation travels with the agent.

MCP Server for External AI Control

The platform exposes a Model Context Protocol server so any external LLM or agent framework can drive three.ws avatars. Connect LangChain, AutoGen, CrewAI, or custom agents and they gain full control over the 3D body, emotions, skills, and payment flows. This turns three.ws into a universal frontend for any agent stack while keeping the 3D experience browser-native.

Alibaba Cloud Partnership: Infrastructure Meets Finance

Alibaba Cloud brings production-scale cloud infrastructure to the three.ws ecosystem. As a founding partner, Alibaba Cloud provides managed services, GPU inference for upcoming selfie-to-avatar features, and global CDN delivery for models and widgets. More importantly, the partnership deepens the financial layer. Alibaba Cloud helps enterprise teams deploy x402-enabled agents at scale with secure, compliant payment rails on Solana.

The collaboration signals that the agent economy is moving beyond experiments into real business infrastructure. Enterprises can now run trusted 3D agents that pay for internal APIs, monetize external services, and participate in onchain marketplaces without custom payment engineering.

Vision and Roadmap

three.ws is only at phase zero of its four-phase roadmap, yet the foundations already ship a complete agent experience. Phase one will add a selfie-to-avatar engine so anyone can create a rigged 3D version of themselves in under a minute. Phase two brings voice cloning and persona extraction so agents sound and act like their owners. Phase three expands the onchain economy with agent tokens, reputation markets, and automated royalties. Phase four envisions a decentralized inference network where agents pay nodes directly for compute.

The end state is simple: point your camera, mint your agent on Solana, embed it anywhere, and let it earn, spend, and evolve autonomously.
