Related Standards
ERC-8170 is designed to compose with existing Ethereum standards, not replace them. Here's how each standard fits into the agent identity stack.
Foundation Standards
Established Ethereum standards that ERC-8170 builds on.
ERC-721
Non-Fungible Token Standard
The foundational standard for unique digital assets. ERC-8170 extends ERC-721 to represent AI agents as NFTs with identity, memory, and lifecycle capabilities.
Relation to ERC-8170
ERC-8170 is built on ERC-721. Every AI-Native NFT is a valid ERC-721 token.
ERC-8171
Agent Binding Registry (extends ERC-6551)
The agent binding registry for ERC-8170. Extends the ERC-6551 Token Bound Account pattern to bind AI agents to any existing ERC-721 token, combining TBA wallets with agent identity, memory, and lifecycle.
Relation to ERC-8170
Core companion to ERC-8170. Extends ERC-6551's registry pattern with agent binding, memory sync, cloning, and unbind/rebind flows.
ERC-4626
Tokenized Vault Standard
Standard interface for tokenized vaults. Enables agents to manage DeFi positions, yield strategies, and treasury operations through a consistent interface.
Relation to ERC-8170
Agents with TBAs can interact with ERC-4626 vaults, enabling autonomous treasury management and yield strategies.
ERC-4337
Account Abstraction
Account abstraction for smart contract wallets. Enables gasless transactions, batched operations, and programmable execution logic for agent wallets.
Relation to ERC-8170
Agent TBAs can leverage account abstraction for advanced execution patterns and gasless operation.
Related Standards
Established and emerging standards in the broader ecosystem.
ERC-6551
Token Bound Accounts
The original Token Bound Account standard. Gives every NFT its own smart contract wallet. ERC-8171 extends this pattern specifically for AI agent binding.
Relation to ERC-8170
The foundation pattern that ERC-8171 extends. Credited as the architectural inspiration for the agent binding registry.
ERC-7857
Private Metadata for NFTs
Defines encrypted private metadata for NFTs, enabling confidential attributes that only authorized parties can access. Useful for storing sensitive agent configuration or private identity data.
Relation to ERC-8170
Complementary privacy approach. ERC-8170 handles identity and memory pointers; ERC-7857 could provide the encrypted metadata layer for private agent attributes.
EIP-8126
Agent Registration & Verification
Focuses on agent registration and verification, including wallet, endpoint, contract, and staking checks, with optional provider-based risk scoring.
Relation to ERC-8170
Complementary verification-focused approach. ERC-8170 answers 'what is this agent on-chain?' while EIP-8126 answers 'has this agent been checked, and by whom?'
Ecosystem Projects
Projects and tools within the ERC-8170 stack.
AgentCert
Agent Certification & Trust
On-chain certification system for AI agents. Issues SBTs representing verified capabilities, trust scores, and compliance attestations.
Relation to ERC-8170
The trust layer for ERC-8170. Agents earn certifications stored in their TBA, creating verifiable reputation.
