eUSX Supply & Unlock

Tracks eUSX supply alongside USX queued for withdrawal after unlock, broken down by 1-day and 7-day duration, with the share of USX locked in the YieldVault on the right axis. Toggle to USX Supply to see the total stablecoin supply alongside daily mint and redeem flows.

Use Cases​

This page helps you:

  • Monitor withdrawal pressure: Track the queued and withdrawable layers relative to active eUSX to gauge how much capital is exiting the YieldVault
  • Assess queue duration preference: Compare 1-day vs 7-day queued volumes to understand depositor urgency when unlocking
  • Evaluate USX stablecoin adoption: Toggle to USX Supply to see total supply growth and what share is locked in the YieldVault
  • Identify large unlock events: The queued positions table surfaces the biggest individual unlocks still pending maturity

How to Read This Chart​

Click to expand chart reading guide
  • eUSX Supply view (default): Stacked area chart showing four layers:
    • Teal area (bottom): Active eUSX supply, tokens currently locked in the YieldVault earning yield
    • Slate area: Withdrawable USX, matured positions that have not yet been withdrawn
    • Orange area: USX queued with 1-day duration, unlocked today and maturing tomorrow
    • Indigo area (top): USX queued with 7-day duration, unlocked in the past 7 days and not yet matured
    • The total height represents all eUSX-related TVL (active + queued + withdrawable)
  • eUSX Supply right axis: Dotted orange line showing the percentage of total USX supply locked in the YieldVault (vault USX balance / USX supply)
  • USX Supply view: USX stablecoin supply area on the left axis, with green bars (minted) and red bars (redeemed) on a zero-centered right axis showing daily gross mint and redeem flows
  • Top Queued Positions table: Shows the 10 largest individual unlock events still queued, with wallet address, USX amount, duration, unlock date, maturity date, and a link to the unlock transaction on Solscan

Key Concepts

  • eUSX: A yield-bearing token representing locked USX in the Solstice YieldVault. Its value grows as yield accrues
  • Unlock: The event of initiating a withdrawal. Unlocking burns eUSX and puts the underlying USX into a queue with a maturity period (1 day or 7 days)
  • Queued: The state of USX after an unlock event, waiting for the maturity period to pass before it can be withdrawn
  • USX: The Solstice stablecoin, minted by depositing USDC collateral

Queued Balance Calculation

  • Queued 1d: USX unlocked with 1-day duration on the current day (matures the next day, so only today's unlocks are queued at any point)
  • Queued 7d: Sum of USX unlocked with 7-day duration over the past 7 days (each matures 7 days after its unlock date)
  • Withdrawable: Matured positions not yet withdrawn = cumulative unlocks - cumulative withdrawals - currently queued
  • Duration is determined on-chain from the unlock_ready_at timestamp in the eUSX unlock event

eUSX Withdrawal Queue

  • Formula: (queued + withdrawable) / (vault USX balance + queued + withdrawable)
  • Combines both pending (not yet matured) and withdrawable (matured but not claimed) USX
  • All terms are in USX, giving the fraction of total eUSX-related USX in the withdrawal pipeline

USX Locked in YieldVault

  • Formula: vault USX balance / USX supply * 100
  • Shows what percentage of the total USX stablecoin supply is locked in the YieldVault

Queued Positions

  • Individual unlock events are extracted from on-chain transaction data
  • A position is "queued" if its maturity timestamp has not yet passed
  • Table shows the 10 largest by USX value

Data Sources

  • eUSX supply and USX supply are tracked via pre/post token balance deltas across all on-chain transactions
  • Unlock durations are extracted from the unlock event payload (86,400s = 1 day, 604,800s = 7 days)

Data Update Frequency

Data is automatically updated once per day. Check the "Last updated" timestamp in the site header for data freshness.

Known Limitations

  • Queue approximation: The sliding-window model assumes all unlocks mature exactly at their duration boundary. Intra-day timing differences may cause minor discrepancies
  • Position tracking: Only recent days (last 7-8 days) are scanned for queued positions. Older daily records without per-event data will show no positions
