The Statics Dollar is a collateralized dollar system with a fungible senior
token (USDstx), series-scoped junior Risk Shares (ethLEV), and two families
of collateral profiles. The Dollar's collateral, issuance, health, insurance,
and recovery live in the separate StaticsDollarCoreDiamond; users reach them
through typed gateway functions on StaticsDiamond.
#Tokens
| Token | Standard | Role |
|---|---|---|
USDstx | ERC-20 Permit | Fungible senior Dollar claim |
ethLEV | ERC-1155 | Series-specific residual Dollar risk for volatile profiles |
Risk Shares are series-scoped: the claims of two series are never interchangeable, even across a successor migration.
#Two profile families
| Family | Mints | Risk Shares | Notes |
|---|---|---|---|
| Volatile | Equal nominal senior Dollar and series Risk Shares | Yes | e.g. WETH collateral; recombination returns collateral |
| Pegged | Senior Dollar only | No | Direct collateral wrapper with independent mint/redeem fees |
Volatile profiles issue equal nominal amounts of senior Dollar and series Risk Shares. Recombining equal senior and junior claims returns proportional collateral when health permits. Pegged profiles are direct collateral wrappers — minting pulls nominal collateral plus a fee; redemption burns Dollar and returns proportional collateral less its fee.
#The gateway
Users never call the Core diamond directly for ordinary actions. StaticsDiamond
exposes a typed gateway: depositETH/depositWETH, recombineToWETH/
recombineToETH, pegged mint and redeem, pairing vault redemption, and the
atomic mint-and-recompose helpers. Each typed entrypoint carries its own permit
variant.
Expired volatile-series risk recovery is separately permissionless. It burns the required senior and Risk Share claims, settles the expired recovery book, and may issue successor pairs. Unlike basket-loan recovery, this path includes a positive quoted keeper bounty paid to its caller.
#Health gates the whole system
Core evaluates every configured profile independently and reports global health
as Healthy, Impaired, Recovering, or Unavailable. A bad or unavailable
profile cannot be masked by surplus in another profile. Global collateral exits
latch after impairment and require 48 continuous healthy hours before ordinary
exits reopen. See Solvency, transitions and recovery.
