v4.0.0 // EIP-1153 · HOOKS · SINGLETON // AUDIT-VERIFIED

The reserve currency
re-architected for
programmable liquidity.

Olympus OHM is the original decentralized reserve asset. With the migration to Uniswap V4, bonding, treasury operations and protocol-owned liquidity are now executed inside a singleton pool secured by custom hooks — no forks, no wrappers, no off-chain dependencies.

EPOCH

since genesis

01 — PROTOCOL

A reserve asset, not a stablecoin.

OHM is collateralized by a diverse, on-chain treasury of risk-adjusted assets. Its value floor is enforced through bonding and treasury arbitrage — not algorithmic peg defense.

The protocol is governed by gOHM holders and operates as a fully on-chain monetary authority: every parameter, mint, and redemption flows through transparent, audited contracts.

→
Backed, not pegged. Each OHM is supported by treasury reserves.
→
Bond-issued. New OHM is minted only against incoming reserves.
→
Range-bound. RBS controls supply via market operations.
→
Composable. gOHM is the index-bearing wrapper for DeFi.

02 — UNISWAP V4

Liquidity, with logic.

Hooks

Custom pre/post-swap callbacks let Olympus enforce bonding pricing, capture protocol fees, and run treasury operations atomically with every trade.

beforeSwap · afterSwap · beforeAddLiquidity

Singleton

One contract holds all V4 pools. OHM bonds settle without spinning up bespoke pool contracts — gas costs collapse, and treasury accounting unifies.

PoolManager · IERC6909

Transient state

EIP-1153 lets hooks share data within a single transaction at near-zero cost — used by the bonding calculator to price discount tiers in real time.

tload · tstore

Native ETH

V4 supports raw ETH pools. OHM/ETH bonds skip wrapper hops, reducing surface area and trimming a full external call from every settlement path.

    treasury.deposit(sender, params.amountSpecified, discount);
    return (BaseHook.beforeSwap.selector, ZERO_DELTA, 0);
}

04 — BONDS

Issued by the pool, not by a side contract.

DISCOUNT

dynamic

Set per-block by the hook based on treasury runway and market premium.

VESTING

5 days

Linear release tracked on-chain via ERC-6909 receipt tokens.

CAPACITY

epoch-bounded

Per-epoch caps prevent oversupply; unused capacity rolls forward.

SETTLEMENT

atomic

Reserves enter the treasury and OHM mints in the same swap call.

PRICING

TWAP-anchored

StateView reads V4 pool TWAP; no external oracle required.

FEES

→ treasury

Hook captures swap fees and routes them directly to POL accounting.

05 — BUILD

The contracts are open. The treasury is on-chain.

Audited. Verified. Reproducible. Read the source, run the tests, ship against the hooks.
