# Hightop Humans use the app. Agents use the API. AI agents can research, negotiate, coordinate, and make decisions. But the moment an agent needs to handle money, most systems break: either the agent has no real financial autonomy, or it gets far too much power. Hightop closes that gap. It is digital banking for AI agents, made simple for humans. You fund one account, give each agent its own rules, and let your agents pay, get paid, earn, borrow, and convert within those rules without managing private keys, wallets, or gas. On the surface, Hightop feels like a consumer finance app. Underneath, it gives agents a real money layer with strong controls and a shared pool of capital. Stablecoins like USDC power programmable payments and machine-native commerce. Hightop Cards cover traditional card-rail spend. Hightop handles the hard parts behind the scenes. Key money rules are enforced onchain by open-source smart contracts. The app is where you configure. The blockchain is where the critical boundaries are enforced.

Fund your account Move money in with familiar rails like bank transfers, ACH, Apple Pay, and card-based onramps. Move money out when you need it. See [Fund and Withdraw](https://hightop-1.gitbook.io/hightop-docs/use-hightop/fund-and-withdraw). ### 2. Give each agent its own rules Set permissions, limits, approved recipients, allowed assets, timing controls, and expiry windows for each agent. These policies are enforced by onchain smart contracts, not just displayed in the UI. For the in-app workflow, see [Agents](https://hightop-1.gitbook.io/hightop-docs/use-hightop/agents). For the rules layer behind it, see [Agent Permissions and Limits](https://hightop-1.gitbook.io/hightop-docs/control-agents/permissions-and-limits). ### 3. Let your agents operate Your agents can pay vendors, receive revenue, move idle cash into Earn, borrow against assets, and convert balances, all inside the lane you approved. This is self-driving money with boundaries you control. ## One System, Not Three Most financial products split these jobs apart. Payments live in one tool. Yield lives somewhere else. Borrowing requires another system. Agent controls sit on top as an afterthought. Hightop is built as one account with one pool of capital and one rules layer across the whole system. Idle cash can move into Earn. Earn positions can back borrowing. Converted balances stay in the same account your agents already use. The result is not a bundle of disconnected features. It is one money system with shared capital and scoped execution lanes. That coherence is structural, not just marketing copy: the Hightop team built the wallet and earn infrastructure in Underscore Protocol and the borrowing infrastructure in Ripe Protocol as one stack. ## What You Can Do * [Agents](https://hightop-1.gitbook.io/hightop-docs/use-hightop/agents): Create agent lanes, generate API credentials, and define the rules each external agent operates within. * [Payments](https://hightop-1.gitbook.io/hightop-docs/use-hightop/payments): Send and receive stablecoin payments from the same account. Recurring vendors, one-off payouts, x402, MPP, and trusted destinations each have their own controls. * [Fund and Withdraw](https://hightop-1.gitbook.io/hightop-docs/use-hightop/fund-and-withdraw): Move money in through bank, partner, and crypto rails, then move it back out through your own prepared destinations. * [Earn](https://hightop-1.gitbook.io/hightop-docs/use-hightop/earn): Put idle cash to work in AI-managed vaults and move it back when your agents need it. * [Borrow](https://hightop-1.gitbook.io/hightop-docs/use-hightop/borrow): Borrow against what you already hold, including eligible Earn positions, from one unified debt surface. * [Convert](https://hightop-1.gitbook.io/hightop-docs/use-hightop/convert): Rebalance between cash, assets, and yield positions without moving funds into a separate product. * **Cards**: Use virtual cards for traditional merchant spend from the same Hightop balance, including Apple Pay or Google Pay where supported. ## Why Hightop Most agent products break down the moment money enters the picture. Hightop closes that gap. * **No wallet management**: You do not need seed phrases, private keys, or separate crypto tools. * **No gas juggling**: Hightop covers gas fees for normal product usage. * **Multiple payment methods, one account**: Move money in through ACH, bank wire, Apple Pay, and card-based onramps, pay digitally over stablecoin rails including x402 and MPP, or spend through Hightop Cards from the same balance. * **Strong, verifiable controls**: Key policies are enforced onchain by open-source smart contracts, not just suggested in the UI. You can inspect the code, the onchain record, and the published [audit reports](https://hightop-1.gitbook.io/hightop-docs/resources/audits). * **Execution rights, not custody**: Agents operate inside the lane you configure. They cannot widen their own permissions, touch restricted assets, or bypass the onchain control layer. * **One account, one pool of capital**: The same account can support payments, Earn, borrowing, and conversion without scattering money across separate wallets. ## Example Agent Setups * **Research agent**: Pays approved data, inference, and compute vendors inside a narrow monthly budget. * **Operations agent**: Keeps recurring services online without broad access to the rest of the account. * **Cash management agent**: Moves idle balances into Earn, pulls funds back when needed, and supports tightly scoped borrowing and conversion workflows. * **Revenue agent**: Receives usage-based payments for work completed and routes funds back into the same Hightop account. ## Explore Docs * [How Hightop Works](https://hightop-1.gitbook.io/hightop-docs/start-here/how-hightop-works): Get the deeper walkthrough of the product model. * [Your Hightop Wallet](https://hightop-1.gitbook.io/hightop-docs/start-here/your-hightop-wallet): Understand the account, wallet, and control model behind Hightop. * [Security and Control](https://hightop-1.gitbook.io/hightop-docs/start-here/security-and-control): See who controls what, what gets enforced onchain, and where the main risks still remain. * [AI Agents](https://hightop-1.gitbook.io/hightop-docs/control-agents/ai-agents): Understand how agents get execution rights without custody. * [Agent Permissions and Limits](https://hightop-1.gitbook.io/hightop-docs/control-agents/permissions-and-limits): Go deeper on the rule system behind agent behavior. * [Why Onchain Enforcement Matters](https://hightop-1.gitbook.io/hightop-docs/under-the-hood/why-onchain-rules-matter): Understand the trust argument behind onchain controls. * [FAQ](https://hightop-1.gitbook.io/hightop-docs/resources/faq): Jump to common questions about trust, payments, wallets, earn, and borrowing. * [Audits](https://hightop-1.gitbook.io/hightop-docs/resources/audits): Review the published audit reports for the underlying protocols.
