Repay DeFi Loans on Any Chain with One Transaction

DeFi didn’t fail because of complexity.
But it definitely didn’t succeed because of simplicity.

Today, repaying a loan means:

  • Finding the right protocol
  • Switching to the correct chain
  • Connecting the right wallet
  • Bridging assets (if needed)
  • Hoping everything lines up

It’s fragmented. Slow. And unnecessary.

LendPay fixes that.

One Payment. Any Chain. Direct Execution.

Product: lendpay.nautilus.sh

LendPay introduces a simple idea

Pay with USDC from one chain. Execute repayment on another.

  • No bridging.
  • No manual navigation.
  • No protocol hopping.

Just:

  1. Enter your wallet
  2. Select your position
  3. Pay

Everything else is handled.

How It Works

LendPay connects three layers:

  • Payment Layer — Pay with USDC (e.g. on Base)
  • Execution Layer — Automated workflow execution (via KeeperHub)
  • Protocol Layer — Target protocol (e.g. DorkFi on Algorand)

The flow is simple:

  1. You submit a payment
  2. The system verifies it
  3. A workflow is triggered
  4. Repayment executes on the destination chain
  5. You get confirmation

You never leave the interface.

Why This Matters

Cross-chain UX is still broken.

Even experienced users deal with:

  • Wallet fragmentation
  • Liquidity routing issues
  • Manual execution risk
  • Time delays

LendPay removes all of that.

You don’t think about:

  • Chains
  • Bridges
  • Wallets

You think about:

“I want to repay my loan.”

And it happens.

Powered by Execution, Not Navigation

This isn’t another bridge UI.

This is a shift in model:

  • From manual interaction → intent-based execution
  • From chain-specific UX → chain-agnostic actions

The user pays.
The system executes.

Built with KeeperHub

LendPay leverages KeeperHub to:

  • Trigger workflows from payments
  • Execute cross-chain actions
  • Track execution state

Combined with a pay-to-execute model, this enables:

  • Fully automated repayments
  • Cross-chain coordination
  • Deterministic outcomes

Demo

The current demo shows:

  • Paying with USDC on Base
  • Repaying a loan on Algorand (DorkFi)
  • Real-time execution tracking
  • Single transaction UX

No switching networks.
No bridging assets manually.

Private beta

We are accepting applications for the LendPay private beta. Go to lendpay.nautilus.sh for the product overview and how to request access. The live repayment app is available only to accepted beta participants.

What’s Next

This is just the start.

The same model can extend to:

  • Liquidations
  • Refinancing
  • Portfolio rebalancing
  • Any cross-chain action

If an action can be defined, it can be executed.

The Direction

LendPay is part of a larger shift:

Users don’t need better dashboards.
They need systems that act on their behalf.

One payment.
One intent.
Execution anywhere.
