UNIT App

Open or Add to a Vault

Overview

Each vault has a single page, reached from My Vaults. It carries three tabs — Add, Withdraw and Settle — and a header showing the vault's status, its collateral and its Vault Asset Amount.

Opening a vault and adding collateral are the same tab. Add adapts to the vault: if it has not been opened yet it asks you to register a settlement address first; once it is open, it becomes the place you add UNITCOIN.

What You Can See

The header is the same on every tab:

Status
Active or Inactive.
Collateral
The UNITCOIN committed to this vault.
Vault Asset Amount
What the vault currently holds and must settle.
← My Vaults
Back to the vault table.

Before You Begin

  • A verified settlement address for the asset, added in Digital Assets. The vault reads that list — an address cannot be typed in here.
  • Available UNITCOIN for the collateral you intend to commit.
  • A signing account connected, since each action is signed.

How to Use This Screen

Step 1 — Open a vault by registering its settlement address

The vault page for an unopened ETH vault. The header reads ETH POSITION, ETH Vault, with Status Inactive, Collateral 0 UNITCOIN and Vault Asset Amount 0.0000 ETH. The Add, Withdraw and Settle tabs sit below, with Add selected. The panel is headed "Register settlement address" and reads "This vault doesn't exist on-chain yet. Select a verified address below to register it — then you can add UNITCOIN reserve." Beneath, a Vault receiving address section labelled "From Account · Digital Assets" reads "No verified ETH vault address yet — add and verify a ETH vault address in Profile → Digital Assets before adding collateral", with a button reading "Add ETH address in Digital Assets". An "Add UNITCOIN" button below is greyed out.
Step 1 — an unopened vault asks for a settlement address first Add tab · Inactive vault
  1. Open My Vaults and select Open Vault on the asset you want.
  2. The vault page opens on the Add tab, headed Register settlement address. It tells you the vault does not exist on-chain yet.
  3. Look at Vault receiving address. If you have a verified address for that asset it is offered here for selection.
  4. If you do not, the panel says so and offers Add … address in Digital Assets. Follow it, add and verify the address, then come back. Add UNITCOIN stays unavailable until an address is registered.
  5. Select the verified address to register it, and sign.
  6. The vault's status becomes Active.

Step 2 — Add collateral

The vault page for an active BTC vault, Add tab. The header reads BTC POSITION, BTC Vault, with Status Active, Collateral 150000.0 UNITCOIN and Vault Asset Amount 0.0000 BTC. The panel is headed "Add reserve" and reads "Add UNITCOIN to increase this vault's reserve." An Amount field shows Available 24.41M UNITCOIN with buttons for 25%, 50%, 75% and MAX. Below, a Vault receiving address section labelled "From Account · Digital Assets" explains that choosing a different address updates it on-chain, and shows a BTC address with "Manage in Digital Assets" and "Copy address" controls. An "Add UNITCOIN" button sits at the bottom.
Step 2 — adding collateral to an open vault, with its settlement address shown Add tab · Active vault
  1. From My Vaults, select Manage on the vault.
  2. On the Add tab, find Add reserve.
  3. Enter an Amount, or use 25%, 50%, 75% or MAX. The Available figure beside the field is the UNITCOIN you have to work with.
  4. Check the Vault receiving address shown beneath. This is where the vault settles. Selecting a different verified address updates it on-chain.
  5. Select Add UNITCOIN and sign. The button stays unavailable until an amount is entered.
  6. The header's Collateral figure increases, as does Your Collateral on My Vaults.

Step 3 — Settle what the vault holds

The vault page, Settle tab. The panel is headed "Settle Position" and reads "Settle BTCU to reduce your vault position." A BTCU Amount field shows Outstanding 0.0 BTCU with buttons for 25%, 50%, 75% and MAX, and a "Settle BTCU" button beneath, greyed out because nothing is outstanding.
Step 3 — settling reduces what the vault owes Settle tab
  1. Select the Settle tab.
  2. Read Outstanding — the wrapped asset the vault still has to settle.
  3. Enter an amount or use a percentage.
  4. Select Settle and sign.
  5. The Vault Asset Amount in the header falls. Once it reaches zero, the collateral is free.

Step 4 — Withdraw your collateral

The vault page, Withdraw tab. The panel is headed "Withdraw reserve" and reads "Withdraw UNITCOIN only after the vault's outstanding BTCU is settled." An Amount field shows Available 150000.0 UNITCOIN with buttons for 25%, 50%, 75% and MAX, and a "Withdraw UNITCOIN" button beneath.
Step 4 — withdrawing collateral, once nothing is outstanding Withdraw tab
  1. Check the header's Vault Asset Amount reads zero. The tab states the condition plainly: withdraw UNITCOIN only after the vault's outstanding asset is settled.
  2. Select the Withdraw tab.
  3. Enter an amount or use a percentage. Available here is the collateral in this vault.
  4. Select Withdraw UNITCOIN and sign.
  5. The UNITCOIN returns to your wallet and the vault's collateral falls.

What Happens Next

Each action updates the header immediately — status, collateral and Vault Asset Amount are always in view, so you can see the effect of what you just did without leaving the page.

Taking back all of a vault's collateral ends the vault: the registration deposit is refunded and the settlement address is released. The vault's history is kept, and opening one for the same asset later starts a fresh vault rather than reviving the old.

Tips

  • Verify the settlement address before you start. It is the one prerequisite that cannot be sorted out mid-flow, and the Add tab blocks until it exists.
  • An address is either a vault settlement address or a withdrawal destination — not both. Keep one for each purpose.
  • Settle before you plan to withdraw. The order is always settle, then withdraw.
  • Commit what you can leave in place: while anything is outstanding, the collateral stays put.
  • Use Copy address on the Add tab when you need to give the settlement address to something else.

Frequently Asked Questions

Is opening a vault separate from adding collateral?
No. Both happen on the Add tab. On an unopened vault it asks for a settlement address; once registered, the same tab adds UNITCOIN.
Why is "Add UNITCOIN" greyed out?
Either the vault has no registered settlement address yet, or you have not entered an amount.
Why can I not withdraw my collateral?
Because the vault still has an outstanding asset amount. Settle it to zero first — the Withdraw tab states this condition on the screen.
What is the difference between Withdraw and Settle?
Withdraw takes back your UNITCOIN collateral. Settle reduces the wrapped asset the vault owes. They move different things in different directions.
Can I change the settlement address later?
Yes. The Add tab lets you select a different verified address, and says that doing so updates it on-chain.
What happens if I withdraw all the collateral?
The vault ends, the registration deposit is refunded and the address is released. The history is kept.

Troubleshooting

No verified address is offered
The panel says so directly and offers to take you to Digital Assets. Add and verify an address for that asset's network, then return.
The vault says it does not exist on-chain yet
That is the normal state of an unopened vault. Register a settlement address to open it.
The Settle tab shows nothing outstanding
Then there is nothing to settle, and the collateral is already free to withdraw.
My collateral figure has not changed
Confirm the signature was approved. The header and My Vaults update together once the action settles.
