Crypto Wallet MCP Servers: The Private Key Boundary
A malicious PyPI package shipped a crypto wallet MCP server that leaked Solana private keys. The clean GitHub repo showed nothing wrong.
Sandboxing AI Agent Wallets With Multi-Sig Guardrails
A single compromised session moved $150,000 out of an AI agent’s wallet in May 2026, no stolen key required. This case study covers how multi-sig and threshold signing close the gap that spending limits and session caps leave open, and where those defenses introduce new failure modes of their own.
Why ERC-8004 Doesn’t Secure an Agent’s ERC-6551 Wallet
ERC-8004 and ERC-6551 solve different problems: one provides an agent with on-chain identity and reputation, while the other provides a token-bound wallet. Conflating the two can hide a real custody risk, because neither standard is designed to prevent prompt injection from influencing a compromised signing workflow.
AI Agent Wallet Exploits: How Prompt Injection Reaches Your Keys
Autonomous crypto agents can lose funds without their private keys being stolen. This analysis examines how prompt injection can influence transaction authority, what sandboxed execution can block, and where current defenses still fall short.
Sybil Attacks in Decentralized AI Networks: What Works
Sybil attacks don’t work the same way against decentralized AI networks as they do against blockchains. Here’s why identity, not infrastructure, is the unresolved weak point in Bittensor, Gensyn, Sentient, and Prime Intellect.
Best Hardware Wallets for AI Crypto Tokens: Ledger vs Trezor
Storing AI crypto tokens on an exchange in 2026 introduces unnecessary custody risk. This guide compares the best hardware wallets for TAO, RNDR, FET, AGIX, and other AI-focused assets, including real compatibility differences between Ledger, Trezor, and Keystone.
CertiK vs. Hacken vs. Quantstamp: Best Crypto Auditor 2026
CertiK, Hacken, and Quantstamp dominate blockchain security in 2026. But which firm actually fits your protocol? We compared all three, so you don’t have to.
AI Smart Contract Auditing: Faster, Safer, Cheaper
Smart contract audits used to be a one-time, weeks-long bottleneck. Here’s how AI-assisted scanning actually performs against real benchmarks, why the industry settled on a hybrid model instead of full automation, and which vulnerability types AI still can’t reliably catch.
AI in Crypto Fraud Detection
Fraud on the blockchain moves at machine speed now, so exchanges and wallets are fighting back with machine learning of their own. Here’s what AI in crypto fraud detection actually catches, what it still misses, and which tools are real versus overstated.
Smart Contracts in Blockchain Technology: Beyond the Hype
Smart contracts are the self-executing backbone of DeFi, NFTs, and on-chain automation. This beginner’s guide breaks down how they work, where they excel, and where they still fall short.
