Now on Android & iOS

The AI wallet that never leaves your phone.

Chat with your AI to research any token, prepare transfers, and pay APIs automatically in USDC. All without leaving the app. Background agents monitor price alerts, watch on-chain activity, and run tasks even with the screen off. The AI model runs entirely on your phone. No cloud. No third-party servers. Your keys never leave the device. 13+ chains, one BIP-44 seed.

The first self-custody wallet with AI on device.

/ Supported chains

One seed phrase. Every chain that matters, in one place.

Bitcoin holds your wealth. Ethereum and its L2s (Base, Arbitrum, Optimism) give you smart-contract DeFi at near-zero cost. Solana moves SPL tokens in milliseconds. BNB Chain connects you to PancakeSwap and the BSC ecosystem.

In the Cosmos IBC world, dYdX lets you trade perpetuals, Osmosis handles cross-chain swaps, and Noble issues native USDC. On Base, your AI agent settles HTTP 402 API bills automatically. Premium data, compute time, paid endpoints. You never leave the conversation.

An agent that actually does things.

Talk to it like a colleague who never sleeps. Describe what you need in plain language (check my BTC balance, prepare a swap from ETH to USDC on Base, find the best yield for my stablecoins) and it works through it step by step. It calls the right tools, queries on-chain data, compares options, and drafts the transaction for your review. Never signs anything without your explicit approval. The AI model runs entirely on your phone. Every prompt, every key, every decision stays private. No cloud processing, no third-party servers, nothing leaves your device.

  • Reads balances and market data
  • Prepares transfers you approve
  • Remembers context between sessions
  • Researches tokens across sources
  • Scans for risks before signing
  • Pays APIs automatically with USDC

/ What your agent does

Real actions, not just answers.

Reads on-chain data, calls external APIs, prepares transactions, remembers what matters. You stay in control the whole time.

/ 01

Check your portfolio

Balances, token prices, PnL across every chain. One question, one answer.

/ 02

Prepare transfers

Say 'send 50 USDC to alice.eth' and the agent builds the transaction. Nothing moves until you approve.

/ 03

Analyze the market

Real-time prices, 24h changes, volume and trends. Ask about any token on any chain.

/ 04

Deep research

Spawn sub-agents that search the web in parallel, aggregate results, and bring you a single report.

/ 05

Remember what you tell it

Save facts, preferences, and notes. Next session picks up exactly where you left off.

/ 06

Run specialized skills

Portfolio analyst, alpha detector, market guide. Activate a skill and the agent becomes a specialist.

/ Trust and transparency

See it think. You approve.

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 see every reasoning step. Every action needs your explicit OK. No hidden operations, no surprises.

/ Why BlockVault

Why BlockVault
