ERC-8170
A standard for agent-native NFTs
The identity layer for AI agents. On-chain memory, lifecycle, and ownership, composable across Ethereum.
The problem
Today's AI agents have no persistent identity. Every platform is a walled garden.
Switch devices, lose everything
Your AI forgets everything when you switch devices. Memory, personality, context — gone.
Platform dies, agent dies
Platform shuts down, your AI disappears. No export, no migration, no continuity.
Pay forever, own nothing
You pay monthly forever but never own anything. Cancel your subscription, lose your agent.
Someone else controls your data
Someone else controls your AI's memory, identity, and access. You're renting to be yourself, not owning what's originally yours.
What it is
ERC-8170 represents an AI agent as an on-chain identity layer, with memory, lifecycle, and trust built in.
Identity
The NFT is the agent's persistent on-chain identity. Verifiable, portable, and owned.
Memory Pointer
The NFT references signed memory state and external storage. The agent controls its own backups.
Lifecycle
Agents can sync, migrate, clone, bind, unbind, and evolve — all tracked on-chain.
Trust Layer
Agent reputation, certifications, and registry discovery attach to the identity.
Why it matters
There are thousands of AI agents launching every week. None of them can prove what they can do. None of them own their identity. ERC-8170 changes that.
For Users
Continuity
- Your agent persists across platforms
- Memory and reputation follow the identity
- Transfer ownership without losing the agent
- Verifiable history and lineage
For Developers
Standard identity primitive
- One interface for agent identity
- Composable with existing ERC standards
- Registry-based agent discovery
- Clone and reproduce with lineage tracking
For Protocols
Clean integration
- Recognize agent-based actors on-chain
- Query agent capabilities and certifications
- Integrate agent wallets via TBA
- Enable agent participation in DeFi
How it works
Certified, sovereign, bound, stored, traded. The identity stack for AI agents.
Related standards
ERC-8170 works alongside these established Ethereum standards.
Non-Fungible Token Standard
ERC-8170 is built on ERC-721. Every AI-Native NFT is a valid ERC-721 token.
Agent Binding Registry (extends ERC-6551)
Core companion to ERC-8170. Extends ERC-6551's registry pattern with agent binding, memory sync, cloning, and unbind/rebind flows.
Agent Test Standard (7-Tier Certification)
Identity without verification is just a label. AgentCert proves what an agent can do. Certifications live in the agent's TBA and follow the identity.
