ERC-8170
A standard for agent-native NFTs
The identity layer for AI agents. On-chain memory, lifecycle, and ownership, composable across Ethereum.
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
ERC-721 made unique digital ownership standard. ERC-6551 let NFTs act through wallets. ERC-8170 adds identity, memory, and lifecycle. ERC-8171 binds it all to any NFT.
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
ERC-8170 sits within the composable Ethereum standards stack, connecting identity to accounts, vaults, and trust.
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.
Tokenized Vault Standard
Agents with TBAs can interact with ERC-4626 vaults, enabling autonomous treasury management and yield strategies.
Account Abstraction
Agent TBAs can leverage account abstraction for advanced execution patterns and gasless operation.
