Introduction
Paboxo is a lending market for Stock Tokens on Robinhood Chain.
Paboxo lets you borrow against Stock Tokens without selling them, and lets lenders earn yield on the stablecoin the borrowing is denominated in.
If you hold NVDA as a Stock Token and want cash without closing the position, you deposit it as collateral and borrow USDG against it. If you hold USDG and want yield, you supply it to a market and earn what borrowers pay. Nothing here is custodial: the contracts hold the assets, and the rules below are the only things that move them.
What makes this different from lending against ETH
A Stock Token tracks an instrument that stops trading. Equity markets close overnight, at weekends, and on holidays, and the price feed stops with them. A lending market built for assets that trade 24/7 gets this wrong in an expensive way — it either treats a stale weekend price as live, or it treats a closed market as an oracle failure and freezes everything.
Paboxo treats a closed market as a distinct, expected state. While the market is closed the last price stands, borrowing and liquidations pause, and withdrawals stay open. You are never trapped in a position because the exchange happens to be shut, and nobody is liquidated on a price that has not been able to move.
That single decision shapes most of what follows: market hours, oracles, and the liquidation rules.
What you can do
| Supply | Lend USDG to a market, earn the borrow rate less a reserve factor |
| Borrow | Deposit a Stock Token or WETH, borrow USDG against it |
| Repay | In USDG, or directly with the collateral you hold |
| Earn vault | Supply USDG once and let it be allocated across markets |
| pUSD | Mint a stablecoin against collateral, as a separate engine |
Where it runs
Robinhood Chain — an Arbitrum Nitro chain. Paboxo is currently deployed on testnet (chainId 46630). Every address, parameter and number in these docs that describes a live deployment is the testnet one, and is labelled as such.
Testnet carries none of the mainnet assets: the Stock Tokens, USDG, WETH and price feeds there are mocks published with the deployment. Treat testnet numbers as a demonstration of the mechanism, never as a statement about mainnet economics.
Stock Tokens are not offered to US, Canadian, UK or Swiss persons. See restrictions.
Not audited
Paboxo has not been audited by an external firm. An audit is a precondition for mainnet, not a formality afterwards. Until it has happened, treat this as software to read rather than software to trust — the risks page is the honest list.
