Local-first identity, memory, and secrets for AI agents. Portable state across models and harnesses.

Persistent Claude Code agents with scheduling, sessions, memory, and Telegram.

Attestix - Attestation Infrastructure for AI Agents. DID-based agent identity, W3C Verifiable Credentials, EU AI Act compliance layer, delegation chains, and reputation scoring. 47 MCP tools across 9 modules.

Agent Gateway by Simplaix

Agentic Identity & Agentic Security System

The open root-of-trust for agent identity on the internet. A public, federated registry of trusted attestation issuers — the agent runtimes authorized to vouch for agents acting on behalf of humans. Services verify agent attestations against this registry to determine if the issuing runtime is legitimate.

SOUL.md — open file format for giving AI agents persistent identity. Spec, JSON schema, examples, and validator.

Identity infrastructure for AI agents. Local-first, model-agnostic. Not just another memory tool.

The open standard for AI agent personas. One file. Persistent identity.

Create and register ERC-8004 trustless AI agents on any EVM chain — Ethereum, BNB Chain, Base, Arbitrum, Optimism, Polygon, and more. Zero-dependency standalone UI for on-chain agent identity registration, reputation, and validation. Mint ERC-721 NFT agent identities with metadata, service endpoints, A2A/MCP discovery, and x402 payment support.

Auth for AI agents and humans. First-class agent identity, MCP OAuth 2.1, delegation, audit. TypeScript, edge-native, MIT.

Standardizing identity and connection orchestration for autonomous agents. A provider-agnostic, zero-trust framework for managing API integrations, OAuth2, and OIDC for in multi-agentic networks

Open infrastructure for AI agents — identity, storage, and more. Self-hostable microservice suite. / 面向 AI Agent 的开放基础设施——身份、存储及更多能力。可完整自托管的微服务套件。

XAP (eXchange Agent Protocol): open economic protocol for autonomous agents.

Agent Cards define the verifiable identity and capabilities of autonomous agents — binding ENS names to verbs, schemas, x402 entrypoints, and discovery metadata. Strictly validated, ERC-8004 aligned, and built for deterministic interoperability across runtimes and agent networks.

Open protocol and reference runtime for sovereign AI agents. Persistent cryptographic identity, signed execution receipts, fail-closed governance — verifiable end-to-end.
