AI Agents Can Now Transact Via MetaMask Without Accessing Private Keys, Says CoinFello

A new OpenClaw skill from CoinFello addresses a key security issue with AI agents using crypto.

The team behind AI agent CoinFello today announced the release of an open-source skill that lets AI agents securely connect to MetaMask and execute on-chain transactions, without ever handling a user’s private keys.

The skill lets OpenClaw-based personal AI agents, known as MoltBots, transact with designated amounts of crypto from an existing MetaMask wallet, without the wallet’s owner giving up custody of their private keys, per a press release shared with The Defiant.

The agent skill is built via the MetaMask Smart Accounts Kit, using ERC-4337 smart accounts and ERC-7710 delegations. CoinFello’s founder and CEO, known as Jacob C, was previously lead of operations at MetaMask.

The release addresses a core vulnerability in how most AI agent wallets currently operate: agents are typically given direct access to private keys or API credentials, which are then vulnerable to prompt injection attacks, per the release.

CoinFello says its approach allows users to grant agents only the narrowly scoped permissions needed for a specific task.

“If we want agents to participate meaningfully in the onchain economy, we need a security model that is better than handing an autonomous system a private key,” said Brett Cleary, CTO at CoinFello.

MetaMask didn’t publicly comment on CoinFello’s skill release today, but ahead of the skill’s debut at ETHDenver in February, MetaMask’s product team signaled support for the approach.

“We’re pleased to collaborate with the CoinFello team as they bring agent-driven experiences to users through the MetaMask Smart Accounts Kit,” Ryan McPeck, product lead at Consensys for the MetaMask Smart Accounts Kit, was quoted as saying at the time, adding:

“We see a future where AI agents can safely act on behalf of users using granular, transitive permissions that allow individuals to define how activity is executed on-chain.”

Supported capabilities include ERC-20 token swaps, bridging across Ethereum Virtual Machine (EVM) chains, NFT interactions, staking, lending, and multi-step trading strategies — all triggered via natural-language prompts. The skill is released under the MIT license, per the release.

The launch lands as the OpenClaw and MoltBot ecosystem has surged in recent months. As The Defiant reported, the viral growth of AI-only social platform Moltbook — mostly populated by OpenClaw agents — drove record token activity on Base-based launchpad Clanker earlier this year.

Yesterday, Axios reported that Meta, the parent company of Facebook, Instagram and WhatsApp, has acquired Moltbook, bringing its two founders into Meta’s AI division.

The DEATH BETS Act: Why Lawmakers Are Moving to Shut Down America’s Fastest-Growing Gray Market

Published

on

Brian Armstrong's Bold Prediction: AI Agents Will Soon Dominate Global Financial

TLDR:

  • THE DEATH BETS Act seeks to ban prediction contracts tied to war, terrorism, assassination, or individual death.
  • Lawmakers cited $500M in wagers on U.S.–Iran strike timing as evidence of rising conflict speculation markets.
  • Bill removes discretion from regulators and sets a clear ban on violent event contracts on U.S. exchanges.
  • Platforms like Kalshi and Polymarket face scrutiny as war prediction markets attract political attention.

DEATH BETS Act legislation introduced in Washington aims to prohibit prediction markets from listing contracts tied to war, terrorism, assassinations, or individual deaths.

Lawmakers say speculative trading around military conflicts and geopolitical crises has exposed regulatory gaps within U.S. derivatives oversight frameworks and created ethical concerns.

Lawmakers Move to Ban Death and War Event Contracts

The DEATH BETS Act was introduced by Mike Levin and Adam Schiff. The proposal seeks to block regulated prediction markets from offering contracts tied to violent geopolitical events.

The bill would prevent exchanges registered with the Commodity Futures Trading Commission from listing contracts related to war, terrorism, assassination, or an individual’s death. 

Lawmakers say the current regulatory framework leaves gaps that allow controversial markets to appear.

Under the Commodity Exchange Act, the CFTC already holds authority to restrict contracts tied to war or terrorism. However, regulators must determine whether such contracts violate public interest standards before taking action.

Supporters of the bill argue that the discretionary nature of the rule allows prediction markets to operate in gray areas. The DEATH BETS Act aims to remove that uncertainty by clearly banning contracts tied to violent events or fatal outcomes.

Rep. Levin pointed to recent speculation involving military conflict. According to the lawmaker, more than $500 million was wagered on the timing of U.S. military strikes on Iran.

Sen. Schiff warned that these markets may encourage traders to profit from classified information or geopolitical instability. Lawmakers argue that markets linked to violent events raise national security concerns.

Prediction Market Activity Fuels Regulatory Debate

Prediction platforms such as Kalshi and Polymarket allow traders to speculate on real-world outcomes. Contracts function similarly to binary options, where traders buy shares representing event probabilities.

Recent geopolitical events have driven heavy activity on these platforms. During tensions involving Iran, traders placed large wagers predicting when military strikes might occur.

A multi-outcome contract on Polymarket reportedly attracted more than $500 million in wagers. Traders could purchase shares tied to specific strike dates and profit if the event occurred during that timeframe.

Reports later suggested several suspected insider accounts generated more than $1.2 million in combined profits from related positions. These findings intensified scrutiny from policymakers.

Another contract on Kalshi asked whether Iranian Supreme Leader Ali Khamenei would remain in power by a certain date. The market reached roughly $54 million in trading volume before trading was halted.

Other markets have speculated on the removal of Nicolás Maduro from power and the capture of Ukrainian territories during the Russia-Ukraine conflict.

Some contracts also explored scenarios involving nuclear escalation or leadership changes during active geopolitical crises. Several were later removed following public criticism.

Lawmakers say these examples illustrate how prediction markets can transform live conflicts into tradable financial events. The DEATH BETS Act aims to establish clear boundaries as the industry expands globally.

Privacy, Bitcoin Mining, United States, Zcash

Digital asset infrastructure company Foundry Digital plans to launch a mining pool for Zcash in April 2026, expanding beyond Bitcoin mining infrastructure. The company said the pool will be designed for institutional and publicly traded miners seeking compliance-focused mining services.

The new pool will be based in the United States and built on the same infrastructure used by Foundry USA Pool, which is operated by the company. Foundry said the service will include reporting tools and payout systems intended to meet the operational requirements of institutional miners.

Zcash is a privacy-focused cryptocurrency which features an encrypted ledger using zero-knowledge proofs. A mining pool is a service that allows multiple miners to combine computing power and share block rewards, increasing the chances of earning consistent payouts.

A spokesperson for Foundry told Cointelegraph that the company decided to build a the new mining pool because “Zcash addresses something we believe is genuinely important: the idea that financial privacy is foundational to economic freedom, and that privacy and compliance can coexist.” They added: 

When institutional and public miners can mine Zcash through infrastructure built to their standards, it brings new hashrate to the network and strengthens its security.

Foundry Digital was founded in 2019 and provides mining infrastructure and related services for digital asset companies. Its Foundry USA Pool is one of the largest Bitcoin mining pools by hashrate share. Foundry said it expects the Zcash pool to begin operations in April 2026.

The announcement comes days after developers who previously worked at Electric Coin Company raised more than $25 million to continue developing a privacy-focused wallet for Zcash.

Zcash garners attention amid price volatility

Zcash, launched in 2016, allows users to send transactions without publicly revealing details such as wallet addresses or transaction amounts. The network is based on Bitcoin’s codebase but uses zero-knowledge proofs, known as zk-SNARKs, to enable optional “shielded” transactions alongside standard transparent ones.

In 2025, Zcash became one of the most widely discussed privacy-focused assets in crypto, with comments from industry figures, including Arthur Hayes, Naval Ravikant and Mert Mumtaz, helping drive interest in the network and its native token, ZEC (ZEC).

The rally pushed Zcash up nearly 600% over the past year, climbing from below $35 in March 2025 to as high as $698.87 on Nov. 16, 2025, according to CoinGecko data. The token has since pulled back, falling 58.7% year-to-date from about $512 on Jan. 1 to roughly $212 at the time of writing.

Even with the renewed attention, the network’s mining activity remains concentrated among a small number of pools.

Data from Poolbay shows ViaBTC controlling about 31.7% of total hashrate, followed by F2Pool at roughly 15.8%, with smaller shares distributed across pools such as 2Miners and Antpool.
