Venue Admin

The venue operator (the address that called createVenue) has exclusive administrative control over the venue. This role is immutable — there is no function to transfer venue ownership.

Where to administer a venue

Drive everything from the OddMaki App. Open your venue's dashboard and use the Settings, Access, Markets, Earnings, and Integration tabs. Venue-level admin is not in the Venue Starter — that's your branded trading frontend, not the operator console.

For automation, every flow below also has an SDK equivalent.

Pausing and Unpausing

Pause a venue to halt all trading and market creation. Existing orders remain on the book but cannot be matched or filled.

OddMaki App: Settings → Status and toggle the switch.

SDK:

// Pause
const tx = await client.venue.setPaused(1n, true);

// Unpause
const tx = await client.venue.setPaused(1n, false);

Pausing is scoped to individual venues — there is no global protocol pause. Use this for emergency situations or maintenance.

Pause vs. Suspend

Two distinct controls exist:

• Pause (venue operator) — self-service on/off switch, the operator can pause and unpause at will
• Suspend (protocol owner) — a protocol-level lock on a venue; only the protocol owner can un-suspend

Suspend is reserved for protocol emergencies and is not something a venue operator controls.

Updating Venue Configuration

Fees

Update trading fee tiers at any time. Changes take effect immediately for all subsequent trades.

OddMaki App: Settings → Fees — enter the new venue fee (bps) and creator fee (bps), then Save.

SDK:

const tx = await client.venue.updateFees({
  venueId: 1n,
  venueFeeBps: 150,    // 1.50%
  creatorFeeBps: 50,   // 0.50% (carved from venue fee)
});

Constraints:

• venueFeeBps must be between 1 and 200
• creatorFeeBps must be ≤ venueFeeBps

Market Creation Fee

The market creation fee defaults to 0 and is updatable any time (it used to be set at creation and immutable; that's no longer the case).

OddMaki App: Settings → Fees → Market creation fee.

SDK:

import { parseUnits } from 'viem';

await client.venue.updateMarketCreationFee({
  venueId: 1n,
  newFee: parseUnits('10', 6), // 10 USDC, or 0n for free creation
});

Venue Details and Access Control

Update the venue name, metadata, access control gates, and fee recipient.

OddMaki App:

• Settings → Info — name and metadata URI (the app uploads the description to IPFS and writes the resulting URI as the venue metadata field).
• Access — view the current trading and creation gates, swap them, deploy new gates, or manage a whitelist inline.
• Earnings → Fee recipient — change the address that receives fees and the venue share of market creation fees.

SDK:

const hash = await client.venue.updateVenue({
  venueId: 1n,
  name: 'Updated Venue Name',
  metadata: '{"category": "sports"}',
  tradingAccessControl: tradingAccessControl,   // address or 0x0 for open
  creationAccessControl: creationAccessControl, // address or 0x0 for open
  feeRecipient: feeRecipient,                   // cannot be zero address
});

Oracle Parameters

Update the UMA reward and minimum bond for future markets.

OddMaki App: Settings → Oracle — enter the new reward and min bond (in USDC), then Save.

SDK:

const hash = await client.venue.updateOracleParams({
  venueId: 1n,
  umaRewardAmount: parseUnits('10', 6),   // 10 USDC
  umaMinBond: parseUnits('5', 6),          // 5 USDC
});

Pause Individual Markets

You can also pause and unpause individual markets on your venue.

OddMaki App: open the market from the Markets tab → market settings → Pause / Resume.

SDK:

await client.market.pauseMarket(marketId);
await client.market.unpauseMarket(marketId);

Market Tags and Metadata

Tags and metadata URIs for markets and groups are event-only (not stored onchain, indexed by the subgraph). Only the market creator or venue operator can update them.

Venue Starter: on a market page, the creator or venue operator can edit tags and the market image from the per-market settings sheet — the starter uploads the image to IPFS and writes the resulting URI as the market's metadata.

SDK:

await client.market.updateMarketTags({ marketId: 1n, tags: ['sports'] });
await client.market.updateMarketMetadata({ marketId: 1n, metadataURI: 'ipfs://…' });
await client.market.updateMarketGroupTags({ marketGroupId: 1n, tags: ['elections'] });
await client.market.updateMarketGroupMetadata({ marketGroupId: 1n, metadataURI: 'ipfs://…' });

Editing market tags from the OddMaki App is on the roadmap but not yet shipped — use the Venue Starter or the SDK in the meantime.

What Can't Be Changed

Reading Venue Data

Read the complete venue configuration onchain:

const venue = await client.venue.getVenue(venueId);

Returns the full VenueData struct including fees, oracle params, access control addresses, and active status. The OddMaki App's Settings tab surfaces all of this for you.
