USDsui yield on NAVI, with the rewards handled for you

Supplying USDsui on NAVI pays a base rate plus a reward in vSUI that someone has to claim and sell. Deposit USDsui, get jnUSDSUI, and the vault does both: it supplies to NAVI and turns the vSUI back into USDsui every 6 hours.

How the vault earns

The two parts of NAVI's USDsui yield arrive differently. Interest is added to your supply on its own, while the vSUI reward sits unclaimed until someone collects it and swaps it.

Step 1

Deposit USDsui

You get jnUSDSUI, a Sui coin worth your share of the vault's USDsui on NAVI plus its idle cash.

Step 2

The keeper supplies it

Every 10 minutes it supplies new deposits to NAVI's USDsui pool and keeps about 2% idle for instant exits.

Step 3

Rewards become USDsui

Every 6 hours it claims NAVI's vSUI reward and swaps it into USDsui inside the vault, which raises the share price.

Risks

  • Exit liquidity. NAVI's USDsui pool is heavily borrowed, around 90% in mid-November 2026. A large withdrawal needs free USDsui in the pool, so its ticket can wait until borrowers repay or new suppliers arrive.
  • Rate and reward risk. The base rate moves with borrowing demand and NAVI can change or end the vSUI reward at any time.
  • NAVI risk. A bug, oracle failure, pause or governance change at NAVI affects the vault directly.
  • USDsui risk. A USDsui depeg hits the vault's value one-for-one.
  • Smart-contract and keeper risk. New code with internal reviews only, and deposits sit idle if the keeper is down.

Questions

What does the USDsui Vault do?

It supplies your USDsui to NAVI's USDsui pool at 1x. NAVI pays a base supply rate plus a reward in vSUI. Every 6 hours the keeper claims the vSUI and swaps it into USDsui inside the vault, so the reward ends up in the jnUSDSUI share price.

What APY does it pay?

The rate is variable: NAVI's USDsui supply rate plus the vSUI reward, minus the vault's fees. The base rate follows how much of NAVI's pool is borrowed and has moved by several points in a single day, so the vault page in the app shows the live estimate instead of a fixed number.

Does the vault borrow?

No. NAVI pays its reward on the net deposit, supplied minus borrowed, so borrowing USDsui to supply it again would only add interest. The keeper's target loan-to-value is zero.

How fast can I withdraw?

About 2% of the vault stays idle, so small exits are paid in the same transaction. Larger exits become a ticket that the keeper funds on its next run, usually within 10 minutes, as long as NAVI's pool has free USDsui.

What are the fees?

A 0.60% entry fee and a 0.10% exit fee, both kept in the vault for remaining holders, plus a 10% performance fee on gains above the high-water mark.

Is the vault audited?

Not externally. The contract has had internal reviews and deposits are capped at 9,990 USDsui while it is in beta. Only deposit what you can afford to lose.
