Balances, token prices, PnL across every chain. One question, one answer.
The AI crypto wallet with background agents.
Tell your AI what you need in plain English. Research a token, prep a transfer, pay an API in USDC. It does it all inside the chat. Background agents watch your price alerts, follow on-chain activity, and run tasks with the screen off. The model runs on your phone, not on someone else's server. No cloud, no third party, no relay. Your keys never leave the device. 13+ chains under one BIP-44 seed.
The first self-custody wallet with AI on device.
Smart Crypto Agents that actually do things.
Talk to it like a colleague who never sleeps. Tell it to check your BTC balance, prep a swap from ETH to USDC on Base, or find the best yield on your stablecoins. It walks through it step by step, calling the tools it needs, pulling on-chain data, comparing options, and drafting the transaction for you to review. It never signs anything on its own. The model runs on your phone. Every prompt, every key, every decision stays private. No cloud processing, no third-party servers, nothing leaves your device.

Background AI Agents
Reads on-chain data, calls external APIs, prepares transactions, remembers what matters. You stay in control the whole time.
It runs in the background while you go about your day. It watches prices, follows on-chain activity, and acts on your rules even with the screen off.
Prepare transfers
Say 'send 50 USDC to alice.eth' and the agent builds the transaction. Nothing moves until you approve.
Analyze the market
Real-time prices, 24h changes, volume and trends. Ask about any token on any chain.
Deep research
Spawn sub-agents that search the web in parallel, aggregate results, and bring you a single report.
Remember what you tell it

The first self custodial wallet with AI on Device .
Your Keys, Your AI, Your coins.
Live reasoning trace
Every step the agent takes streams in real time. Which tool it selected, which chain it queried, what price it read, and the exact reasoning behind each conclusion. No silent background processing, ever.
Human-in-the-loop
Any state-changing action (a transfer, a file write, an external API call) pauses automatically and shows you a plain-language summary. Nothing executes until you tap Approve. You can reject at any point.
Zero data leaves
On-device inference means every prompt, every key, and every transaction stays on your hardware. No cloud processing, no third-party AI servers, no telemetry leaves your device. What happens on your phone stays there.
Scoped permissions
Each session grant is scoped to a specific domain, amount, and time window. Grants are timestamped, logged on-device, expire automatically, and can be revoked individually. No blanket access, no surprises.
You can see every step it takes. Anything that touches your funds waits for your explicit OK. No hidden operations, no surprises.
