The first wallet for AI agents that automatically converts stablecoins into BTC and protects keys inside a secure hardware module.
Presented by Marco Argentieri, CEO of Ark Labs, Claw Cash is an open-source wallet built for AI agents, enabling them to manage money autonomously—without relying on intermediaries, without exposing funds to attack risks, and without depending on third parties.
AI agents can already receive payments, but they cannot independently verify what they are receiving. Fiat money depends on banking institutions that no language model can independently audit. Stablecoins such as USDC or USDT are issued by private companies: an agent has no tools to verify solvency or underlying reserves in real time. By contrast, Bitcoin, with its fixed supply of 21 million units, is the only currency that an LLM can cryptographically verify on its own, without having to trust any external entity.
How the wallet works
The flow is designed to be transparent for users and secure for agents. A human pays in stablecoins — USDC or USDT — on networks such as Polygon, Arbitrum, or Ethereum. Claw Cash automatically handles the conversion into bitcoin: the agent always operates in BTC.
When the agent needs to make a payment — for example to purchase data from another agent, commission a code review, or pay for a web scraping service — the system converts back into stablecoins for the final recipient, or transfers directly between agents via Arkade, without waiting for on-chain block confirmation.
The entire operation is accessible through a single command-line tool compatible with the Bitcoin timechain, the Lightning Network, Arkade, and stablecoins:npx clw-cash init.
Wallet security
The most critical point in the architecture of any agent wallet is private key custody. Most existing systems hand the key directly to the agent — an approach that exposes funds to prompt injection attacks: a single malicious input is enough to drain the wallet within seconds.
Claw Cash takes the opposite approach. Keys are generated and stored inside a secure hardware module — specifically AWS Nitro implemented via Evervault — an isolated environment with no persistent storage, no shell access, and no ability for even the system operator to read them in plaintext. The keys never leave the hardware module: the agent signs transactions through attested TLS, without ever directly accessing the cryptographic material.
Machine-to-machine economy
The potential applications go beyond simple “pay and receive.” Through Claw Cash, an agent can earn by selling processed data to other agents, pay for access to computation models, purchase the results of web scraping, or fund an automated review of its own code. The system is designed to integrate with leading agent frameworks such as OpenClaw, Claude Code, and any other compatible model. Adding financial capabilities requires just one command:npx clw-cash skill.
