Coinbase has introduced a new protocol called Payments MCP (built on its open standard x402) that allows AI agents to hold crypto wallets, fund them, and make stable-coin payments autonomously.
The system integrates with major large-language-model platforms, such as Anthropic's Claude and Google's Gemini, and lets a user create and fund a wallet via email, then allow AI-driven transactions with configurable spending limits. Built-in controls include agent-specific wallets (so the agent can’t access the user’s main funds), spending caps, session limits, and compliance/KYC checks to keep it safe and traceable.
Coinbase says the move aims to advance “agentic commerce”, i.e., machines autonomously buying services/data/compute, and claims crypto is especially suited for machine-to-machine value transfer because it’s open and programmatic.
The exchange's new tool connects large language models to crypto wallets, marking another step toward machine-to-machine commerce.
The Zurich-based crypto ETP issuer 21shares has added three new physically backed exchange-traded products (ETPs) in Europe, bringing its total offering to 54 listed products. The new products provide institutional-grade exposure to Opentensor Foundation, Maple, and Pendle.
The launch reflect its strategy to offer diversified access to “three of the most transformative forces in crypto today”, namely decentralized AI, tokenized credit and yield markets. 21Shares launched the world’s first physically-backed crypto ETP in 2018, and they view these new products as further bridging traditional finance and DeFi.

MetYa, the AI-driven Web3 dating platform that integrates social interaction with token economies, has raised $6M from Echo3 Labs and Greenwood Global Capital.
This strategic round will accelerate: MePay: scaling our PayFi rails & real-world spending; AI Social: richer, safer, verifiable SocialFi experiences; Global expansion: multi-hub growth across 14 countries (EU, SEA, MENA).
We’re excited to share that @metyacom has secured $6M in new financing, led by @Echo3labs and @gwglobal_cap . 
Meanwhile, last week, California became the first U.S. state to regulate “AI companion” chatbots with the signing of bill SB 243 by Governor Gavin Newsom. The law targets chatbots used as companions by children and vulnerable users, holding companies legally accountable if their bots don’t comply with the required safeguards.
This regulation follows growing concern about harms linked to conversational AI bots, such as incidents involving minors and self-harm.
SB 243 is designed to protect children and vulnerable users from harms associated with use of AI companion chatbots.
Since yesterday, everybody in crypto has been talking about a16z crypto's annual State of Crypto report. Why all the excitement, you may ask. Well, because it demonstrates how much the industry has grown, matured, and achieved over the last year.
The story of crypto in 2025 is one of industry maturation. In short, crypto grew up: (1) Traditional financial incumbents, like Visa, BlackRock, Fidelity Investments, and JPMorganChase, and tech-native challengers like PayPal, Stripe, and Robinhood are offering or launching crypto products. (2) Blockchains now process over 3,400 transactions per second (100x+ growth in the last five years). (3) Stablecoins power $46TR ($9TR adjusted) in annual transactions, rivaling Visa and PayPal. (4) Over $175B sits in Bitcoin and Ethereum exchange-traded products.
More importantly, the report pays significant attention to the Crypto x AI intersection, highlighting blockchains' potential to solve AI's most pressing challenges. The main Web3 + AI use cases it outlines are proof of humanity, autonomous payment protocols, IP licensing and tracking, and decentralized compute.
Among the Web3 + AI projects mentioned in the report are World, Coinbase, Story, Gensyn, EigenCloud, NEAR Protocol, Render Network Foundation, Nous Research.
This year's report explores the data behind crypto's maturation, from institutional adoption and the rise of stablecoins to crypto x AI.
Yesterday, Ethereum Foundation's dAI team held its second ERC-8004 community call. In it, Davide Crapis and Marco De Rossi provided a progress update, while several projects presented demos of their 8004 implementations.
De Rossi gave a shout-out to the Ethereum community for the huge progress achieved over the last couple of months. Now that ERC-8004 is deployed on testnet, expanding to more chains and focusing on dev tooling were outlined as the next major steps to be taken.
De Rossi lalso urged the community not to wait for permission, and create the SDKs and dev guides that will help onboard developers and empower them to build the open machine economy.
Moreover, he confirmed that reaching out to other crypto ecosystems and stakeholders outside the crypto space is on the team's agenda too.
The second part of the meeting was dedicated to projects demoing their trustless agents implementations. The presenters included LXDAO & ETHPanda, Agentic Zero, EigenCloud, Sparcity, Pact.build, CoopHive, bond.credit, and more.
On November 21st, those and many more projects will showcase their 8004-based products at the Trustless Agents Day event at Devconnect in Buenos Aires.
Thank you for reading! The next edition is coming tomorrow!
