Guide: Market Creator Setup

This guide shows how to create and verify a Market Creator, then update fields over time.

1) Create a Market Creator

import DepredictClient from '@endcorp/depredict';
 
const { ixs, marketCreator } = await client.marketCreator.createMarketCreator({
  name: 'My Platform',
  feeVault,
  creatorFeeBps: 50, // 0.5%
  signer: adminKey,
});
// send ixs using your wallet/tx builder

2) Verify Collection and Merkle Tree

// (Optional) Create an MPL Core collection (off-chain action via UMI under the hood)
// name and uri are required
const created = await createCoreCollection(program, adminKey, {
  name: 'My Collection',
  uri: 'https://example.com/metadata.json',
  rpcEndpoint: 'https://your-das.example',
});
 
await client.marketCreator.verifyMarketCreator({
  signer: adminKey,
  coreCollection: created ? new PublicKey(created.publicKey) : coreCollection,
  merkleTree,
});

3) Update Fields

// Update name
await client.marketCreator.updateMarketCreatorName({ signer: adminKey, newName: 'New Name' });
 
// Update fee vault
await client.marketCreator.updateMarketCreatorFeeVault({
  signer: adminKey,
  currentFeeVault: feeVault,
  newFeeVault,
});
 
// Update creator fee (BPS)
await client.marketCreator.updateMarketCreatorFee({ signer: adminKey, creatorFeeBps: 75 });
 
// Update merkle tree (validates authority)
await client.marketCreator.updateMerkleTree({ signer: adminKey, newTree: merkleTree2 });

Notes

Creator fee is capped on-chain (2% max)
Collection and tree must be set before opening positions (for NFT minting)
Use different creators to separate platforms or business lines
