/ AI agents · x402

Wallets for autonomous agents.

Your agent pays per request: paywalled articles, API calls, GPU inference, premium data feeds. You set the spending limits, it transacts on its own. No subscriptions, no cards, no custodian in the middle.

/ Why BlockVault

Why BlockVault

Your wallet shops for you. Hunts the best price, pays the API, signs the transaction, brings back the receipt. All while you're asleep or on a call. You set the budget. It does the rest.

  • / 01

    x402 payments via AI chat

    Pay APIs, agents and dApps directly from a conversation. The wallet settles HTTP 402 challenges in-line, no checkout, no copy-paste.

  • / 02

    Local inference with LM Studio

    Run open models on your own machine through LM Studio. Prompts and keys never leave the device.

  • / 03

    Delegated GPU inference

    Burst to remote GPU clouds when you need scale. Each request is metered and paid per-token over x402.

  • / 04

    AI runs on your device

    Inference stays local. Your prompts, your keys, your hardware. No cloud round-trips, no data leaks.

  • / 05

    One seed phrase, every chain

    Control all your wallets and assets with a single BIP44 seed phrase. One backup, done.

  • / 06

    Lower fees, faster trades

    Reduced fees and quicker settlements compared to legacy wallets. More of your money stays yours.

/ Skills · Author the agent

Teach your wallet new tricks.

Skills are tiny Markdown bundles that turn the AI into a portfolio analyst, an alpha scout or a market guide. Use the built-ins, write your own, or import from GitHub.
