Abstract

Titled "From KYC to KYA: Is It Time to Issue 'Identity Cards' for AI Agents?", this article discusses the emerging concept of Know Your Agent (KYA) as AI agents become increasingly autonomous. In Agent-to-Agent (A2A) scenarios, where agents execute contracts, payments, and trades without human intervention, the lack of a shared identity standard creates risks like unauthorized transactions, fraud, and accountability gaps. KYA acts as a trust layer to verify an agent's origin, authority, and accountability. The need for KYA is most critical outside centralized platforms (like Google or Coinbase), such as in decentralized exchanges (DEX), A2A payments, and merchant payments. Several key players are building KYA infrastructure: - **ERC-8004**: A proposed Ethereum standard that issues a unique AgentID as an NFT, building on-chain identity, reputation, and validation systems. - **Visa TAP**: Visa's solution issues agent identity credentials, with transactions verified via triple signatures (legitimacy, delegator, payment method). - **Trulioo**: Extends its KYC/KYB compliance infrastructure using a Digital Passport for Agents (DAP), issued after verifying both the developer and user, and refreshed per transaction. - **Sumsub**: Focuses on post-issuance real-time verification, detecting agent anomalies during transactions using its existing compliance systems. Regulatory bodies are also acting. The EU AI Act mandates operator identification in logs for high-risk AI systems, the US...

The era of AI agents is accelerating, and alongside it, concerns about the uncontrolled creation and behavior of agents are growing. Know Your Agent (KYA) systems, which assign identities to agents and regulate their behavior, are receiving increasing attention. Why is a KYA identity infrastructure needed? Which companies are building it?

Summary

  • AI agents have entered an era of autonomously executing contracts, payments, and transactions, but there are currently no shared standards to verify "who this agent is." In Agent-to-Agent (A2A) scenarios, KYA is gaining more focus than KYC.
  • KYA is not needed in all scenarios. Within centralized platforms (Google, OpenAI, Coinbase), existing KYC is sufficient. Where KYA truly becomes important is in scenarios where independently deployed autonomous agents interact with DEXs, A2A payments, and merchant payments.
  • The KYA standards race has begun:
  • ERC-8004: Issues AgentIDs on top of NFTs, building an on-chain system for identity, reputation, and verification.
  • Visa TAP: Visa issues identity credentials for agents, verified through TAP's triple signature (legitimacy, delegator, payment method).
  • Trulioo: Adopts the SSL CA model, with DPAs issuing DAPs.
  • Sumsub: Layers a KYA system on top of its own compliance system.

Regulatory action has begun at the national level. The EU's AI Act requires high-risk AI system behavior logs to include operator identity. The US NIST has listed agent identity management as a priority standard area. Singapore has released the world's first national-level AI agent governance framework. Just as the 2019 FATF Travel Rule determined which crypto exchanges survived, whether one possesses KYA infrastructure will determine who enters the next market cycle.

Why is KYA Emerging Now?

KYC: The Layer That Reshaped Finance

  • Before 1989, global finance lacked a unified identity standard. This gap made it difficult to track drug money and illicit funds.
  • After the FATF was founded in 1989, KYC became a mandatory requirement in finance, blocking illicit funds at the entry point.

Without Agent Identity, Systems Regress

  • AI agents execute contracts, payments, and transactions without human involvement, but currently, it's impossible to verify "who it is."
  • In A2A environments, accountability becomes blurred, dispute risks increase, and users are exposed to fraud patterns like money laundering.

The Role and Response of KYA (Know Your Agent)

  • KYA (Know Your Agent) is a trust layer that pre-verifies an agent's origin, permissions, and accountability framework.
  • Unverified agents bring three major risks simultaneously: unauthorized transactions, fraud, and accountability gaps.

The Manifestation of KYA's Necessity

KYA is Needed at Every Level

  • Within centralized platforms, user KYC + platform accountability is sufficient. In interoperable scenarios outside platforms, KYA becomes crucial for verifying an agent's specific actions and safety.
  • Within a country (inside a platform), one ID (KYC) is enough to move freely. But once crossing borders (outside a platform), the environment changes, and entry review (KYA) of purpose and trust is needed.

Market Players

ERC-8004: NFT-Based Agent Identity

  • ERC-8004 adds an identity layer on top of ERC-721, minting an NFT as a unique ID for each agent.
  • It also adds three on-chain registries (Identity, Reputation, Validation), serving as identity, reputation board, and verification record respectively.

Two Markets Built by Ethereum Standards, a Third is Coming

  • ERC-20 (Token Issuance Standard): Before standardization, every token needed brand-new code. After ERC-20, most major assets were issued on it.
  • ERC-721 (NFT Standard): CryptoPunks, BAYC, ENS built the NFT market itself upon it. As blockchain integration accelerates in the agent era.
  • ERC-8004 will play the same standardizing role for Agents.

Visa TAP: Authentication on the Visa Rail

Visa issues identity credentials (Agent Intent) to agents, akin to an identity card. Without a key, transactions cannot occur. Keys are issued only after Visa pre-approval. Every transaction is signed and submitted to the merchant.

The merchant receives three signatures, not one: Visa approval, delegator, payment method, all confirmed simultaneously.

Visa: A Strategy to Pull Every Transaction into the Visa Network

  • Just as Visa previously captured payment rails, it is now encapsulating the agent era.
  • Through Visa Intelligent Commerce (VIC), Visa offers a solution bundle that packages KYA with payments.
  • If agent payments still use the card rail, and this bundle becomes the default option, then Visa's market share can remain stable even through the transition.

Trulioo: Extending KYC-Era Verification Infrastructure

  • Trulioo is a compliance operator on the global KYC/KYB rail and is expanding its verification stack to KYA.
  • DPAs play the role of SSL-CAs. Unlike SSL (domain only), DPAs verify developer KYB and user KYC before issuing a DAP.
  • Banks and fintechs legally require human and business identity. As agents enter finance, Trulioo's KYC/KYB position will be further solidified.

DAP, an Agent's Digital Passport, Refreshed with Each Transaction

  • DAP is an agent's digital passport. A DPA verifies the developer (KYB) and user (KYC), packages both into a token, and grants it to the agent.
  • Unlike a paper passport, it is a live token, refreshed and re-verified with every transaction. Once delegation is revoked or anomalies are detected, the DAP is invalidated immediately.
  • KYA is not a one-time verification. Trust must be reconfirmed with every transaction.

Sumsub (AI Agent Verification): Detecting Agent Anomalies

  • Sumsub's approach is: whenever an agent attempts an anomalous transaction, re-verify the currently active human identity.
  • It leverages its verification systems from its compliance business since 2015 to detect agent anomalies more accurately.

Operators with Technology to Address New Threats of the AI Era

  • Other KYA players focus on one-time pre-transaction identity verification. Sumsub focuses on real-time verification post-issuance.
  • As agent permissions expand, anomaly detection becomes crucial; as fraud scales with technology, Sumsub's real-time verification stack gains attention.

Proactive Regulatory Positioning, Shaping Entry Rules

The Gap Caused by the FATF Travel Rule May Recur with KYA

After the 2019 FATF Travel Rule, VASPs diverged based on their ability to bear KYC/AML infrastructure costs. Peers like CryptoBridge and Deribit, unable to afford it, either shut down or moved to less regulated regions.

The EU, Singapore, and the US are already vying for leadership. KYA will become a core layer of the agent era.

KYA Will Differentiate by Market Segment, Not a Single Winner

The real variable in the standards race is not technology, but combinations. Mainstream players have entered the collaboration and combination phase. In the future, who pairs with which merchants, payment networks, and KYC customer bases will determine the leader in each segment.

The market will not have a single winner; it will differentiate by market segment.

Related Questions

QWhat is KYA (Know Your Agent), and why is it emerging as an important concept in the AI agent era?

AKYA (Know Your Agent) is a system designed to verify the identity, authority, and accountability of AI agents, especially in scenarios where they operate autonomously without direct human oversight. It is emerging as a crucial trust layer due to the rise of AI agents that autonomously execute contracts, payments, and transactions. In these Agent-to-Agent (A2A) environments, there is currently no shared standard to verify 'who the agent is,' leading to increased risks like unauthorized transactions, fraud, and accountability gaps. KYA addresses these risks by establishing a trust infrastructure for pre-verifying an agent's source, permissions, and purpose.

QWhat are some key standards and solutions being developed for KYA?

ASeveral standards and solutions are being developed for KYA. Notable examples include: 1) **ERC-8004**: An Ethereum-based standard that uses NFTs (ERC-721) as unique AgentIDs and adds on-chain registries for identity, reputation, and validation. 2) **Visa TAP (Triple Authorization Protocol)**: Visa's solution that issues identity credentials (Agent Intent) to agents and requires triple signatures (from Visa, the delegator, and the payment method) for transaction approval. 3) **Trulioo's DAP**: Extends their KYC/KYB infrastructure to issue a dynamic Digital Agent Passport (DAP) that is re-validated per transaction. 4) **Sumsub (AI Agent Verification)**: Focuses on post-issuance, real-time verification of agents to detect and prevent abnormal behavior using their existing compliance stack.

QIn what scenarios is KYA most necessary, according to the article?

AAccording to the article, KYA is most necessary outside of centralized, walled-garden platforms (like Google, OpenAI, or Coinbase), where traditional user KYC and platform accountability are sufficient. KYA becomes critical in scenarios involving independent, autonomously deployed agents interacting across platforms, particularly in: 1) **Agent-to-Agent (A2A) transactions** (e.g., payments between agents). 2) **Accessing decentralized exchanges (DEXs)**. 3) **Making payments to merchants**. These represent interoperable environments where a lack of agent identity verification creates significant operational and financial risks.

QHow are governments and regulatory bodies responding to the need for AI agent identity management?

AGovernments and regulatory bodies are beginning to act on AI agent governance, effectively pushing the need for KYA infrastructure. Key actions include: 1) **The EU AI Act**: Requires operators of high-risk AI systems to be identifiable in activity logs. 2) **US NIST**: Has prioritized AI agent identity management as a key standard-setting area. 3) **Singapore**: Released the world's first national-level AI governance framework specifically for agents. The article draws a parallel to the 2019 FATF Travel Rule, suggesting that the ability to implement compliant KYA systems will be a determining factor for which entities can participate in the next phase of the AI agent market.

QWhy does the article suggest the KYA market will be segmented, with no single winner?

AThe article suggests the KYA market will be segmented because the key variable for success is not just technology, but the combination and integration of solutions with existing business ecosystems. Major players are entering a 'cooperation-combination' phase. The future market leader in each segment will be determined by which KYA provider successfully partners with which merchants, payment networks (like Visa's approach), and existing KYC customer bases. Therefore, different KYA standards and solutions (e.g., ERC-8004 for the crypto-native ecosystem, Visa TAP for card-based commerce) are likely to dominate different application areas, leading to a fragmented market rather than a single universal winner.

Trend in US Stocks: Jensen Huang's One Sentence Triggers $47 Billion Surge; Google Raises Funds for First Time in 20 Years

U.S. markets reached record highs on June 2nd, but the real story was the intensifying AI arms race, now pivoting from chip supremacy to a scramble for capital to fund compute infrastructure. The day highlighted two stark realities: Nvidia CEO Jensen Huang's endorsement of Marvell Technology as the "next trillion-dollar company" at Computex fueled a historic 32.5% surge, adding $47 billion to its value. Conversely, Alphabet announced its first equity raise in two decades—an $80 billion plan—signaling that even its massive cash flow can't keep pace with soaring AI capital expenditures, forecast to exceed $180 billion in 2026. While the S&P 500 closed above 7,600 for the first time, led by tech and semiconductor stocks (SOXX +5.79%), sector performance was mixed. Alphabet's 4% drop dragged down communications services, illustrating market anxiety over the unsustainable cost of the AI buildout. Hewlett Packard Enterprise soared 25% on stellar earnings, proving AI's benefits extend beyond chip designers to infrastructure providers. Beneath the index highs, concerns linger over extreme concentration in a few AI stocks and geopolitical tensions. The focus now shifts to upcoming economic data, particularly Friday's nonfarm payrolls, which could challenge the market's current "ignore rates, chase AI" mentality.

Variant: Bitcoin, Ethereum, and ZCash Highly Likely to Become Major Stores of Value

At Variant, our investment philosophy centers on enabling individuals to own their money, identity, and data. We believe all tokens fall into two categories: stores of value (SOV) or equity-like instruments. The SOV framework is particularly useful for evaluating Layer 1 (L1) blockchains, which are major monetary coordination protocols. A good store of value should possess: 1) Technical durability, 2) Scarcity, 3) Censorship resistance, 4) Economic productivity, 5) Strong memetics, and 6) Liquidity. The total addressable market for SOV assets is massive, with gold alone valued at $31 trillion. Three L1 assets stand out as prime candidates for becoming major stores of value: Bitcoin (BTC), Ethereum (ETH), and ZCash (ZEC). Bitcoin excels in memetic dominance as "digital gold." Ethereum demonstrates superior technical durability and adaptability through its upgradeable roadmap. ZCash offers exceptional censorship resistance and privacy via its shielded transactions. While digital SOVs outperform traditional ones like gold on many metrics, they still represent a small fraction of the overall SOV market, presenting a significant growth opportunity.

Can DeepSeek Save China One Trillion Dollars?

"DeepSeek and the $1 Trillion Infrastructure Question" The article examines whether DeepSeek's AI optimization breakthroughs could potentially save China $1 trillion in future AI infrastructure costs. The analysis begins with Nvidia's upcoming Vera Rubin AI platform, costing ~$7.8 million, where memory (HBM4/LPDDR5X) constitutes $2 million—a 435% cost increase in one year, highlighting how AI hardware spending is shifting toward expensive memory components. DeepSeek's approach works in the opposite direction. Through three key technical innovations showcased in DeepSeek V4, the company dramatically improves hardware efficiency: 1. **Memory Compression (MLA)**: Re-engineers the attention mechanism to compress long-context memory (KV Cache) by over 90%, drastically reducing expensive HBM usage. 2. **Selective Activation (MoE)**: Employs Mixture-of-Experts architecture where only a small fraction of parameters (e.g., 49B out of 1.6T in V4-Pro) are activated per token, allowing most parameters to reside in cheaper memory/SSD. 3. **Computation Caching**: Reuses previously computed results via cache hits, replacing expensive GPU computations with cheap memory reads. Combined, these optimizations allow the same hardware to produce approximately 4x more tokens, effectively reducing required hardware investment by 75%. DeepSeek's pricing reflects this: a 10-billion token workload costs ~$522 monthly versus ~$9,000-$10,000 for competitors. The $1 trillion savings projection stems from McKinsey's estimate that global AI infrastructure will require ~$5.2 trillion investment by 2030. As China's daily token consumption grows toward quadrillions, even marginal efficiency gains scale massively. With a conservative 4x throughput improvement, China could avoid building tens of thousands of AI data centers equivalent to ~7 trillion RMB ($1 trillion) in saved investment. Critically, this strategy shifts dependency from scarce, expensive GPU/HBM—where China lags—toward more accessible storage, caching, and systems engineering where domestic suppliers like CXMT are gaining strength. Rather than "replacing Nvidia," DeepSeek rebalances AI's value chain away from monolithic hardware dependency. Ultimately, DeepSeek's technical breakthroughs could lower the barrier to AI adoption across Chinese industries by making advanced capabilities affordable at scale—transforming who can access next-generation AI.

Overturning the Mainstream Approach to Hallucinations: Metacognition is the New Solution for Large Models to Break the Hallucination Barrier

This paper, "Hallucinations Undermine Trust; Metacognition is a Way Forward," proposes a paradigm shift in combating AI hallucination. It argues that the current mainstream approaches—striving for omniscience by scaling data/models or having AI abstain from uncertain answers—are fundamentally flawed. The former has inevitable knowledge gaps, while the latter imposes a crippling "utility tax," requiring the rejection of many correct answers to achieve high accuracy, due to models' poor "discrimination" (the ability to distinguish correct from incorrect answers internally). The core contribution is redefining hallucination not as "being wrong," but as "expressing false information with unwarranted certainty." The proposed solution is **Faithful Uncertainty** or **Metacognition**: enabling AI to accurately perceive its internal uncertainty and honestly express it in its language (e.g., using hedging phrases when unsure). This creates a more reliable assistant that provides useful information while signaling its confidence, minimizing harm from errors. The paper emphasizes that metacognition is critical for the era of AI Agents. Without it, Agents cannot intelligently decide when to use tools like search engines, leading to inefficiency and misuse. Key implementation challenges are highlighted: the "bootstrapping paradox" of training with static uncertainty data, the "alignment distortion signal" where human preference training suppresses internal uncertainty cues, and the difficulty of causally evaluating true metacognition vs. its superficial imitation. The paper concludes that the goal should not be an infallible AI, but one that is honest about the limits of its knowledge, thereby building user trust through transparent communication of its certainty.

Hedge by Buying Gold and Oil, Chase Soaring Returns with AI. ‘Dated’ Bitcoin Enters a Bear Market

Bitcoin has recently declined, hitting a two-month low near $66,123, while Ethereum fell to a three-month low around $1,837. Analysts suggest the drop is not merely due to factors like ETF outflows or MicroStrategy's selling but reflects a deeper issue: Bitcoin is losing a broader asset competition. In a near-zero interest rate environment, Bitcoin previously thrived as an outlet for investor dissatisfaction with inflation and limited options. However, the market landscape has shifted. Bitcoin now occupies an "awkward middle ground," facing competition on three fronts. For inflation hedging, investors prefer gold, energy stocks, and commodity producers—assets with tangible backing and clearer pricing power. For growth exposure, AI-related companies with actual revenues and profits are more attractive. Even within crypto, investors can choose stablecoins, exchanges, or infrastructure firms tied directly to adoption, offering clearer business models and leverage. Thus, Bitcoin is no longer the top choice for hedging, growth, or crypto exposure. This shift is evident in market reactions: despite recent warnings about persistent inflation from a Fed official, Bitcoin did not rally as it might have in the past. Instead, capital flowed to assets with direct commodity or energy exposure. The recent ETF outflows and MicroStrategy sales are symptoms, not causes, of this new reality. Investors are becoming more selective, demanding clearer value propositions beyond mere scarcity. The emerging bear case for Bitcoin is not about it being a bubble or failed technology, but that scarcity alone is no longer sufficient.
