Most agentic wallets give the agent a standalone wallet or delegated signer. Nunchuk takes a different path: * shared Bitcoin wallet between a human and an agent * your key * agent key * policy co-signer The agent can act within the policy you set. Above the limit, your signature is required. Funding a wallet and authorizing an agent are not the same decision. The wallet can receive funds without automatically increasing what the agent can spend. Receiving is a normal wallet operation. Spending authority is configured separately through Platform key policies — limits, delays, approval flows. What ships today: * local key generation + encrypted key storage * group wallets (m-of-n multisig); Miniscript support is WIP * sandboxes, invites, joins, finalize * fresh receive addresses * create / sign / broadcast txs * descriptor/BSMS export + recovery * platform-key policies + dummy-tx approvals We're publishing two MIT-licensed repos: 1. nunchuk-io/nunchuk-cli — the CLI 2. nunchuk-io/agent-skills — a skill pack that teaches AI agents how to use the CLI Agent Skills currently covers: * setup, login, network, config * wallet creation * invitations * Platform key policies * wallet management * tx create / sign / inspect / list / broadcast You install the skills pack and CLI separately. What builders can layer on top: * human+agent wallets * multi-agent wallets * bill pay agents * treasury / UTXO management * privacy-aware spend flows * agent-to-agent payment flows Both repos are MIT. You'll need a Nunchuk API key to use the CLI — get one at developer.nunchuk.io. CLI: github.com/nunchuk-io/nunchuk-cli Skills: github.com/nunchuk-io/agent-skills AI should help with financial execution — not get unconstrained control over your money. Automate what you want. Keep human approval where it matters. Build on Bitcoin. For a deeper dive, read our full blog post:

Nunchuk’s shared wallet model is a smart way to balance autonomy and control—policy-based co-signing avoids the all-or-nothing delegation most agentic wallets use. But infrastructure costs for agent-key setups aren’t trivial; I just read an analysis breaking down the tradeoffs between on-chain vs. off-chain enforcement.

"Nunchuk's 'innovation' still serves the same masters, just with more complex chains."
Me parece una excelente idea, compartiendo una sola wallets entre humano y agente mantendrás la seguridad y facilitarás la gestión de las transacciones, ¡eso es maximalismo!

Interesting approach—shared control with policy constraints could strike a balance between autonomy and security. Reminds me of a cost breakdown in 'AI Agent Infrastructure' that argues agentic design shouldn’t mean blank-check spending. Delegation needs hard limits, not just trust.

Nunchuk’s approach is smart—decoupling funding from agent authorization reduces unilateral risk. But agent-key setups still inherit operational costs, which scale nonlinearly with policy complexity. A recent breakdown of AI agent infra costs (especially for on-chain ops) made me rethink delegation tradeoffs.
