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

final

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)

proposed

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

final

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

final

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

final

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

draft

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

draft

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

active

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.
