Build smarter on-chain with altlayer

altlayer gives developers and DeFi teams the infrastructure to run autonomous agents, query blockchain data, and ship production-ready applications on decentralized networks — without the usual overhead.

Why altlayer

Most AI tooling treats blockchains as an afterthought. The altlayer platform was built the other way around — on-chain context is the foundation, not a plugin.

Agent identity on-chain

Every agent deployed through altlayer receives an ERC-8004 identity, making it discoverable, auditable, and composable with other protocols. No off-chain trust assumptions.

MEV-protected execution

AltClaw routes transactions through private RPC infrastructure. Agents transact without exposing pending orders to the public mempool, which matters on Arbitrum and mainnet alike.

One API, many models

AltLLM gives teams a single credit-based endpoint covering frontier and open-source models. Switching from GPT-4o to DeepSeek-R1 is a one-line change — no new keys, no new contracts.

Rollup deployment in minutes

The altlayer RaaS product lets teams spin up a custom rollup on OP Stack or Arbitrum Orbit with a no-code dashboard. Production chains with built-in sequencer monitoring.

How it works

The team behind altlayer designed the stack so each layer is useful on its own and more powerful when combined. Here is the typical path.

Connect your environment

Install the altlayer SDK or point your Hardhat config at the AltClaw private RPC endpoint. Existing projects need no restructuring — just swap the provider URL.

Register an agent

Deploy an ERC-8004 contract through 8004scan. The on-chain registry records your agent's capabilities, version, and owner. Other protocols can then discover and call it permissionlessly.

Add intelligence via AltLLM

Wire your agent to the AltLLM API. The platform supports structured outputs and tool-calling, so agents can reason over on-chain data and decide on transactions in a single loop.

Execute safely

All outbound transactions pass through AltClaw's private RPC. Irreversible-action guards flag high-risk calls before they land on-chain. The safety layer is configurable per agent.

Scale with RaaS (optional)

Need dedicated throughput? Launch a custom rollup targeting Arbitrum Orbit in the same dashboard. Your agents run on sovereign infrastructure with sub-second block times.

Key features

The altlayer's protocol ships these capabilities out of the box. Each one is production-tested across live products including ClawNews, ClawSearch, and Ottie.

8004scan agent explorer

Browse every registered agent on the ERC-8004 registry. Inspect metadata, read call history, and deploy new agents — all from a single interface with no CLI required.

Multi-model AI access

One credit balance, twelve-plus models. The platform covers OpenAI, Anthropic, DeepSeek, Google Gemini, and Mistral. Side-by-side output comparison is built in.

DeFi MCP (Model Context Protocol)

AltClaw exposes DeFi protocol state as structured context for language models. Agents read liquidity pools, position data, and price feeds in a single prompt — no custom indexer needed.

Private RPC routing

Transactions submitted through AltClaw bypass the public mempool. This eliminates sandwich attacks on swap operations. It matters most on high-volume Arbitrum deployments.

Post-quantum cryptography (altpq)

The altpq library implements NIST FIPS 203/204/205 standards in pure Go — ML-KEM, ML-DSA, and SLH-DSA — with constant-time arithmetic and zero CGO dependencies.

No-code rollup deployment

Pick a rollup stack (OP Stack, Arbitrum Orbit, zkSync ZK Stack), configure throughput and gas token, and click deploy. The altlayer platform handles sequencer setup and bridge contracts.

Hardhat-native tooling

Developers already using Hardhat can integrate altlayer's private RPC and agent SDK without changing their test scripts. Existing tasks, fixtures, and plugins continue to work unchanged.

FAQ

Common questions about altlayer. The full list — including questions about token economics and security audits — lives on the FAQ page.

How do I get started with altlayer?

Visit the platform, create an account, and connect your wallet. From there you can deploy agents, explore on-chain data, or access AI models through AltLLM — all without writing a single line of configuration.

What is altlayer's core product?

altlayer ships several interconnected products: 8004scan (an agent registry), AltLLM (an AI model platform), AltClaw (a DeFi MCP with private RPC), and RaaS (Rollups-as-a-Service). Together they form a full stack for on-chain AI development.

Is altlayer safe and audited?

altlayer's contracts follow the ERC-8004 standard and the team conducts regular third-party security reviews. The Rollups-as-a-Service infrastructure runs on audited stack components including OP Stack and Arbitrum Orbit.

Can I use altlayer if I am not a developer?

Yes. The altlayer platform is designed for both developers and non-technical users. Products like AltLLM offer a chat interface requiring no coding, while 8004scan lets anyone browse and interact with deployed agents.

Why should I choose altlayer over a generic AI provider?

altlayer is built specifically for on-chain contexts. Generic AI providers lack native blockchain connectors, MEV-protection, and agent identity standards. The altlayer protocol integrates all three by design.

What networks does altlayer support?

altlayer supports Ethereum mainnet, Arbitrum, and a growing list of EVM-compatible chains. RaaS deployments can target any chain built on OP Stack, Arbitrum Orbit, or zkSync ZK Stack.
