Deep Dive
1. Agent Identity Scan Expansion (19 December 2025)
Overview: This update significantly broadened the functionality of BAS's Agent Identity Scan tool. It now supports more blockchain networks and allows any user to submit verifiable reviews of AI agents, making the ecosystem more transparent and easier to navigate.
The scan now includes networks like BNB Smart Chain Testnet, Base Sepolia, and Ethereum Sepolia, and accepts agents from registries beyond BAS, such as Ethereum Foundation. A new search function lets users filter agents by name, chain, and trust mode. Crucially, the update introduced an attestation-based review system where non-authorized users can submit evaluations, with each reviewer's BNB Passport visible to assess credibility.
What this means: This is bullish for BAS because it makes the platform for AI agents much more useful and trustworthy. Developers can find and integrate agents across multiple blockchains more easily, and the new review system helps users avoid low-quality agents by providing transparent, reputation-backed feedback.

2. ERC-8004 Core Contract V1 Upgrade (17 November 2025)
Overview: This was a major upgrade to BAS's core identity contract, fundamentally changing how AI agents are represented and evaluated on-chain. It turned agents into independent, tradable digital assets and introduced a community-driven reputation system.
The key change was upgrading the IdentityRegistry to inherit the ERC-721 (NFT) standard. This means each AI agent is now a unique NFT that can be owned, transferred, or authorized for use by others. The upgrade also added a feedback system where authorized users can leave detailed interaction data and scores, and an open comment system where anyone can post public reviews.
What this means: This is bullish for BAS as it creates a new, liquid market for AI agent identities and establishes a transparent foundation for agent reputation. It incentivizes the development of high-quality agents, as their value can now be proven and traded on-chain, strengthening BAS's role as a trust layer.

3. First ERC-8004 Public Agent Registry (3 November 2025)
Overview: This update marked the official deployment of the first public registry for AI agents using the ERC-8004 standard on BNB Chain. It provided the basic infrastructure for registering and querying verifiable AI identities.
The registry serves as a central directory where AI agents can register their identity and on-chain behavior. It is integrated with BAS Attestation and BNB Passport, allowing developers to verify both on and off-chain data. At launch, over 120 agents had registered, creating an initial network for the ecosystem.
What this means: This is bullish for BAS because it established the project as a pioneer in on-chain AI identity. By providing the essential tools for developers to build with verifiable agents, it lays the groundwork for broader adoption in sectors like RWA and compliant DeFi.
