Cobo Ships Agentic Wallet — 80+ Chains, Claude MCP Hooked In, Keys Stay Split
Singapore custody veteran Cobo launches an MPC-backed wallet that lets AI agents trade and pay on-chain without ever holding a full private key.
The product
On April 20, Cobo (Singapore-based custody firm) launched the Cobo Agentic Wallet — an MPC-secured wallet purpose-built for AI agents to perform on-chain tasks without ever holding a full private key. It supports 80+ chains including Ethereum, BNB, Arbitrum, and Solana.
Which AI frameworks plug in
Native integrations with Anthropic's Claude MCP (Model Context Protocol), OpenAI's Agents SDK, and LangChain. Agents inherit wallet capabilities through these integrations rather than via raw key access.
The 'Pact' mechanism
Every agent action runs inside a task-specific "Pact" — an agreement that pre-defines permitted and prohibited actions. MPC splits keys into encrypted shares; high-value transactions require user co-signing with tamper-proof audit logs. A custodial mode for high-frequency, low-value transactions is planned next.
Recipes
Pre-built transaction templates cover common flows: swaps, lending interactions, recurring investments, and payments. Agents execute against these templates rather than crafting transactions from scratch.
BlockAI Take
The agentic wallet race is no longer a demo circuit — Cobo, Supra, and Ant Group's Anvita all shipped agent-transaction surfaces this month. The differentiator isn't "can an agent sign?" — it's "how tightly can a human bound what the agent is allowed to do?" Cobo's Pact + MPC answer is currently the most institution-grade in market.
