DOLA’s second life: from Inverse’s early lending experiments to a FiRM-controlled dollar

DOLA is best understood as a changing credit system, not simply a dollar ticker. Inverse Finance began in late 2020, introduced early Stabilizer and Frontier mechanisms, suffered a major Anchor lending exploit in April 2022, and now describes FiRM overcollateralized borrowing as DOLA’s dominant supply route. The key verification question is not only whether DOLA targets $1, but who can expand supply, what collateral backs it, and what rights a holder actually has.

An early stablecoin inside a young lending DAO

Inverse Finance says it was founded by Nour Haridy in late 2020 and is now governed by an Inverse Finance DAO. DOLA emerged as the protocol’s debt-backed stablecoin while Frontier provided the original variable-rate lending context.

The protocol’s historical account says a DOLA Stabilizer launched in February 2021 to facilitate 1:1 DOLA–DAI swaps. That mechanism described a market function, not a legal promise that every DOLA holder owned dollars or DAO assets.

The exploit that changed the risk story

On April 2, 2022, REKT reported an Anchor exploit in which an attacker manipulated the thin INV/WETH market used by the lending oracle, deposited inflated INV collateral and borrowed approximately $15.6 million, including about 4 million DOLA. The event links DOLA’s history to oracle design, collateral valuation and bad-debt management rather than to peg mechanics alone.

Inverse’s current documentation says Frontier is deprecated and existing unbacked borrows are being reduced over time, while FiRM replaced the earlier model with fixed-rate markets, collateral escrows, risk limits and liquidation infrastructure. These are documented product states; future upgrades or governance proposals should not be presented as completed remediation beyond what the live contracts show.

What DOLA represents now

The current DOLA documentation identifies FiRM overcollateralized borrowing as the primary issuance channel. Governance-approved supply ceilings and 24-hour rolling borrow limits constrain each market; the PSM provides a secondary USDS reserve swap, with reserves deposited into a yield-bearing USDS vault according to the project’s account.

DOLA’s verified ERC-20 is immutable according to Inverse’s registry, but Etherscan’s verified ABI includes privileged minting administration. Official Fed documentation says a Fed Chair multisig operates Feds within DAO-approved bounds. Thus immutability limits code replacement, not the economic significance of authorized minters. DOLA is transferable token infrastructure, not documented equity, profit-sharing, reserve ownership or a guaranteed fiat redemption contract.

Governance, bridges and the verification boundary

Inverse distinguishes INV governance from DOLA use: the DAO sets protocol decisions and risk parameters, while working groups and multisigs perform delegated operations. Core DOLA is listed on Ethereum and the docs describe L2 availability, but the reviewed smart-contract page specifically warns that historical CCIP shutdowns apply to sDOLA and sINV lanes; no blanket claim that every Inverse asset has a live bridge should be made.

Before using DOLA as collateral or a peg instrument, verify the live market, Fed ceiling, oracle, minter/operator roles, PSM reserves and any chain-specific deployment. The reviewed materials establish the architecture and historical events, not a permanent guarantee that those parameters remain unchanged.

How the project changed

  1. Late 2020
    Inverse Finance founded

    Inverse’s documentation identifies Nour Haridy as founder and places the protocol’s origin in late 2020; the DAO later became the governing organization.

  2. February 2021
    DOLA Stabilizer launched

    The official DOLA Feds history describes the original Stabilizer as a 1:1 DOLA–DAI swap mechanism, an early peg/liquidity design that predates today’s PSM.

  3. April 2, 2022
    Anchor exploit drains roughly $15.6 million

    REKT reports manipulation of the INV/WETH oracle path followed by borrowing of 1588 ETH, 94 WBTC, about 4M DOLA and 39.3 YFI. The incident became a defining collateral and oracle-risk event in DOLA’s history.

  4. October 2023
    Original Stabilizer deprecated

    Inverse’s current Feds documentation says the Stabilizer was deprecated in October 2023 as AMM Feds and FiRM made it redundant.

  5. 2026-08-25
    FiRM-centered DOLA with PSM backstop

    The current documentation presents FiRM as the dominant DOLA supply route, with PSM reserve swaps, governance-approved ceilings, Fed multisig operations and active collateral-specific markets.

What is DOLA?

DOLA is Inverse Finance's native decentralized stablecoin intended to track one U.S. dollar. The current product is primarily a lending-backed asset: users borrow DOLA from FiRM against eligible collateral, while a Peg Stability Module (PSM) can exchange approved USDS reserves for DOLA. This is materially different from a bank-deposit stablecoin: the documentation describes backing as collateral in FiRM escrows or reserve assets in the PSM.

DOLA sits inside the broader Inverse Finance DAO, alongside FiRM, DBR borrowing rights and INV governance. Holding DOLA itself is not documented as ownership of the DAO, a claim on protocol equity, or a guaranteed redemption right for dollars; its practical rights are ERC-20 transfer and protocol-defined use, while governance and operational authority sit with INV governance, Feds and designated multisigs.

What problem does DOLA solve?

DOLA addresses the DeFi need for a dollar-denominated unit that can be created against crypto collateral rather than through a conventional bank issuer. FiRM's current design targets predictable fixed-rate borrowing, with collateral escrows, liquidation rules, market supply ceilings and daily borrow limits intended to keep outstanding debt backed.

The problem has changed over time. Inverse's original Frontier lending product and AMM-based supply mechanisms were later deprecated; official documentation says FiRM now supplies nearly all circulating DOLA, while the PSM is a smaller peg-defense and liquidation-liquidity backstop. That history matters because DOLA's risk is tied to lending markets, oracle quality, liquidation capacity and governance-set supply limits—not only to secondary-market trading.

How does DOLA work?

DOLA is an 18-decimal ERC-20 on Ethereum at 0x865377367054516e17014ccded1e7d814edc9ce4. Current official documentation describes two issuance paths: FiRM borrowing, where governance-authorized Feds pre-mint within market ceilings and users draw loans against eligible collateral, and the PSM, where approved USDS reserves are exchanged 1:1 for DOLA (with a documented redemption fee). Loans are repaid and DOLA is burned; liquidation systems and collateral factors are intended to preserve backing.

The token contract is verified on Etherscan and exposes operator/minter administration plus mint and burn functions. Inverse's registry says the core DOLA token contract is immutable, so its bytecode is not upgradeable; that does not mean supply is permissionless. Official Fed documentation says a Fed Chair multisig can expand or contract supply within DAO-approved limits, while DAO governance controls parameters and broader protocol decisions. The published contract page does not establish the current operator/minter addresses or prove any legal dollar redemption obligation, so those must be checked on-chain before relying on them.

Key facts

  • Canonical Ethereum token: Dola USD Stablecoin (DOLA), contract 0x865377367054516e17014ccded1e7d814edc9ce4.
  • The verified ERC-20 uses 18 decimals and exposes mint, burn, addMinter/removeMinter and operator functions.
  • Current issuance is primarily through FiRM overcollateralized borrowing; the PSM is a secondary USDS reserve swap and peg-support mechanism.
  • Supply expansion and contraction are performed by specialized Fed contracts within governance-approved limits; the Fed Chair multisig executes operations.
  • Core DOLA token bytecode is documented by Inverse as immutable and non-upgradeable, but immutable code can still contain privileged minter/operator roles.
  • Inverse was founded in late 2020; its original Frontier lending product and February 2021 DOLA Stabilizer are historical mechanisms, while FiRM is the current flagship lending product.
  • The April 2, 2022 Anchor exploit was independently reported at approximately $15.6 million, including about 4 million DOLA, after INV price manipulation.

Frequently asked questions

Is DOLA the same as INV or DBR?

No. DOLA is the dollar-denominated stablecoin; INV is Inverse Finance's governance token; DBR represents DOLA borrowing rights in FiRM.

What backs DOLA today?

Inverse's current documentation says DOLA is backed by collateral locked in FiRM borrower escrows or reserve assets held by the PSM. The mix and limits can change through governance and Fed operations; this is not a statement of bank reserves or a legal dollar claim.

Can DOLA holders vote on Inverse Finance?

The documentation assigns protocol governance to INV holders, not DOLA holders. DOLA holders can use, transfer or deposit DOLA in supported products, but holding DOLA alone is not documented as governance power.

Can the DOLA contract mint or freeze tokens?

The verified ABI exposes mint, addMinter, removeMinter, burn and operator functions. Official docs say Feds can mint and burn within governance-approved limits. The token is documented as immutable and no freeze function appears in the published ABI, but the current operator/minter set and Fed limits require live on-chain verification.

What is the current DOLA product?

FiRM is the current flagship route: users deposit approved collateral and borrow DOLA at fixed rates using DBR. The PSM offers a secondary USDS-to-DOLA reserve swap and peg-defense path. Frontier and most AMM Feds are historical or deprecated.

Does DOLA guarantee redemption for one U.S. dollar?

No legal redemption guarantee is established by the reviewed sources. The protocol describes a 1:1 target and a PSM exchange mechanism, but that is distinct from a contractual right to redeem directly with an issuer for fiat.
