Borrowing Under the Hood#

When you borrow through Hightop, you are not just taking a loan. Your entire portfolio can back a single credit line — and your collateral can keep earning yield the whole time.

Quick example: you hold some ETH and an Earn position. Both back one unified borrowing position. You borrow working capital without selling either asset. Your Earn position keeps generating AI-managed yield while it serves as collateral. You repay when your revenue settles.

Hightop's borrowing runs on a purpose-built lending protocol called Ripe Protocol, which the Hightop team also built. Ripe handles the collateral, the debt, and the safety mechanisms underneath.

Why Borrowing Exists in Hightop#

Sometimes you need capital without selling what you own.

An AI agent running a trading strategy might need working capital before revenue settles. A payments agent might need to cover vendor bills while waiting on incoming receipts. A business might need short-term liquidity while keeping its treasury intact.

Traditional loans do not work at agent speed or agent scale — they take days, require intermediaries, and impose geographic restrictions. Borrowing against your existing assets on Hightop is instant, global, and works around the clock — without bank approvals or intermediaries. The same crypto rails that make payments fast and accessible also make borrowing fast and accessible.

One Loan, Your Whole Portfolio#

Most onchain lending protocols force you to manage separate loans for separate assets. If you have five different assets, you have five different positions — each with its own interest rate, its own liquidation risk, and its own management overhead.

Ripe takes a different approach. Your entire portfolio — whatever you deposit — backs a single unified loan. One position. One interest rate. One set of thresholds to monitor. And the loan is always overcollateralized — you must deposit more in collateral than you borrow, and the protocol enforces this at all times.

Each asset you deposit contributes to your total borrowing power based on its own risk profile. Stablecoins contribute more (they are less volatile), while riskier assets contribute less. The protocol blends all your collateral into weighted terms — your interest rate, your liquidation thresholds, and your overall borrowing capacity all reflect the combined profile of everything you deposited.

This means you do not need to think about which asset to borrow against. You deposit what you have, and the protocol calculates what you can borrow based on the full picture. For AI agents managing borrowing positions autonomously, this is especially valuable — one position to monitor and one set of thresholds to manage, rather than juggling separate loans across different assets.

What You Can Use as Collateral#

Ripe is designed to support a broad universe of asset types. Hightop exposes a supported subset today, with the range expanding over time.

Currently available collateral on Hightop includes:

• Stablecoins like USDC — low risk, high borrowing power
• Established crypto assets like ETH and BTC — moderate risk, strong borrowing power
• Yield-bearing assets like Earn positions — these keep earning yield even while locked as collateral

Each asset type has its own loan-to-value ratio. The protocol combines them into a single position where all your assets work together.

Your collateral backs only your loan — not a shared pool. Another borrower's risk does not affect your position. This isolation is a key part of the design.

Productive Collateral#

This is one of the most important ideas behind Hightop's borrowing model: your collateral does not have to sit idle.

Your Earn positions — the tokens you receive when you deposit into a Core Vault — can be used as collateral on Ripe. That means your assets are earning AI-managed yield while simultaneously backing a loan. You are not choosing between earning and borrowing. You get both.

This is also how Amplified Vaults work internally. An AI agent manages the full strategy — depositing into a Core Vault, using the resulting Earn position as collateral on Ripe, borrowing stablecoins, and deploying the borrowed funds into more yield — all within onchain-enforced boundaries. The productive collateral concept is the building block that makes that strategy possible.

What You Actually Borrow#

Under the hood, Ripe mints a stablecoin called GREEN (designed to track the US dollar) against your collateral when you borrow. GREEN is not borrowed from a pool of other people's deposits — it is created by the protocol for your loan and burned when you repay. Hightop handles the stablecoin layer so you can interact through familiar assets like USDC. You do not need to hold or manage GREEN directly — the mechanics happen behind the scenes.

How a Borrow Actually Happens#

Here is the end-to-end flow when a borrowing action is executed through Hightop:

1. You deposit collateral — assets from your Hightop wallet are deposited into Ripe through a standardized adapter, the same kind of adapter architecture described in Wallet Model.
2. Ripe calculates your borrowing power — the protocol values your full collateral portfolio and determines weighted terms based on what you deposited.
3. The borrow is submitted — Hightop assembles the borrowing action and submits it through the adapter. The wallet's smart contract checks your agent's permissions, limits, and boundaries before anything executes.
4. Ripe mints GREEN — the protocol creates the stablecoin against your collateral position.
5. You receive usable funds — Hightop manages the stablecoin layer, so you interact with familiar assets like USDC.
6. Your position is continuously monitored — Ripe tracks your collateral value against your debt and enforces safety thresholds at all times. You can also configure your own agent to monitor and manage the position — adding collateral or repaying debt automatically to keep the position healthy and avoid liquidation.

When you repay, the flow reverses: debt is reduced, GREEN is burned, and collateral is freed for withdrawal.

All of Hightop's agent controls apply throughout this flow. An agent needs explicit borrowing permission to manage collateral or debt. Spending limits, asset restrictions, and cooldowns apply to borrowing actions just like any other action. The result is two independent layers of protection: Ripe's safety mechanisms protect the lending position itself, and Hightop's agent controls protect you from unauthorized or excessive use of the borrowing capability. Both layers are enforced onchain.

Safety Layers#

Borrowing involves risk. If your collateral loses value — or if interest on your debt accumulates over time — your position can become unhealthy. Ripe addresses this with multiple layers of protection, each designed to intervene before the next one is needed.

Your position moves through zones as conditions change:

• Safe zone — you are below your borrowing limit and can borrow more. Normal operations.
• Liquidation zone — your position has dropped far enough that the protocol begins to liquidate collateral to restore it to health.

Between these two sits the redemption zone — one of Ripe's most distinctive features.

Most lending protocols go directly from "healthy" to "liquidation." Ripe adds an intermediate buffer. When your position enters the redemption zone, other participants in the protocol can pay off a portion of your debt and receive equivalent collateral at face value — no penalty to you. This market-based mechanism helps reduce your debt before forced liquidation begins. You can also proactively reduce your own debt at any time with no penalty.

The exact thresholds between these zones vary by asset type. Stablecoins have tighter thresholds (because they are more stable), while volatile assets have wider buffers.

If liquidation is triggered, the protocol protects as much of your position as possible:

• It takes only what is needed to restore the position to health — not your entire collateral
• Multiple mechanisms run in sequence to minimize the impact
• You keep everything above what was needed to cover the debt

This partial liquidation model is a deliberate design choice. Many lending protocols liquidate your entire position when you cross a threshold. Ripe takes only what is necessary.

Repayment is flexible. There are no fixed terms, no prepayment penalties, and you can repay any amount at any time. Repaying immediately reduces your risk and frees up collateral.

If You Want More Control#

Borrowing through Hightop gives you the default experience — the protocol handles the mechanics, and you or your agents interact through the app or API within configured boundaries.

If you want more direct control over borrowing, you can configure an agent with specific borrowing permissions and restrictions. For example:

• Allow debt management but only with USDC and ETH as collateral
• Set a limit on how much can be borrowed per month
• Restrict the agent so it cannot withdraw collateral below a target ratio

This gives you the same onchain-enforced boundaries, but with your agent executing a borrowing strategy you define — rather than relying on the default experience.

Hightop's borrowing infrastructure is built on Ripe Protocol, which the Hightop team also built. The full source code is available on GitHub.
