Launchpad

The Medialane Launchpad provides four launch formats for creators and organizations. All formats deploy audited Cairo smart contracts directly to Starknet Mainnet — no centralized mint server, no admin key, every rule enforced on-chain.

Formats at a Glance

| Format | Token Standard | Transferable | Best for | |--------|---------------|-------------|----------| | ERC-721 Collection | ERC-721 | Yes | Unique 1-of-1 digital art, photography | | ERC-1155 Edition | ERC-1155 | Yes | Music albums, publications, multi-copy editions | | Collection Drop | ERC-721 | Yes | Timed public mints with supply caps and allowlists | | POP Credential | ERC-721 (soulbound) | No | Event attendance, DAO membership, hackathon completion |

ERC-721 Collection

Deploy a branded collection contract where each token is a unique, individually identified IP asset.

Features

  • Factory pattern via the Collection Registry contract
  • Each token has its own IPFS metadata URI
  • Supports royalty configuration (ERC-2981)
  • Compatible with the Medialane marketplace for secondary trading
  • Berne Convention timestamp embedded at mint

Contract

Collection Registry: 0x05c49ee5d3208a2c2e150fdd0c247d1195ed9ab54fa2d5dea7a633f39e4b205b

ERC-1155 Edition

Deploy a multi-token collection where each token ID can have multiple copies (editions). Ideal for music, publications, limited prints, and any creative work where multiple buyers should hold the same asset.

Features

  • One contract, multiple token IDs and quantities
  • Partial listing support — list 5 of your 100 copies at once
  • Independent price per token ID on the marketplace
  • ERC-1155 receiver hooks for safe transfers
  • Metadata resolves from IPFS base_uri

Contract

ERC-1155 Collection Factory: 0x006b2dc7ca7c4f466bb4575ba043d934310f052074f849caf853a86bcb819fd6

Collection Drop

A timed NFT release with configurable supply, mint window, price, per-wallet limit, and optional allowlists. Every constraint is enforced by the contract — no Medialane backend involvement after deployment.

Configuration Parameters

| Parameter | Description | |-----------|-------------| | maxSupply | Hard cap on total tokens that can ever be minted | | mintPrice | Price per token (ERC-20: USDC, USDT, ETH, STRK, WBTC) | | startTime | Unix timestamp when public mint opens | | endTime | Unix timestamp when mint closes | | maxPerWallet | Maximum mints per wallet address | | allowlist | Merkle root of pre-approved addresses (optional) | | allowlistPrice | Discounted price for allowlist wallets (optional) |

Drop Lifecycle

Deploy → Allowlist phase (optional) → Public mint → Mint closes → Secondary trading

Once minted, tokens are standard ERC-721 and list freely on the Medialane marketplace.

Contract

Drop Factory: 0x03587f42e29daee1b193f6cf83bf8627908ed6632d0d83fcb26225c50547d800

POP Protocol (Proof of Participation)

Soulbound credentials for events, DAO governance, education, and community milestones. POP tokens are non-transferable by design — they represent verifiable on-chain proof that cannot be bought or sold.

Use Cases

  • Events — conference attendance, concert, workshop participation
  • Education — bootcamp completion, course certificate
  • DAO membership — verified contributor status, working group membership
  • Hackathons — winner and finalist recognition
  • Community milestones — early adopter, beta tester, governance participation

Features

  • Non-transferable (soulbound): transfer reverts
  • Gas-free for recipients — organizer sponsors or AVNU paymaster covers fees
  • Self-sovereign: credential belongs to the holder's wallet forever; Medialane cannot revoke
  • On-chain verification: any app or contract can read and verify POP ownership

Minting a POP Credential

Organizers deploy a POP collection contract, upload credential artwork to IPFS, and define the claim window. Eligible addresses are added to an allowlist (Merkle tree or signature-based). Recipients claim directly to their wallet.

Contract

POP Factory: 0x00b32c34b427d8f346b5843ada6a37bd3368d879fc752cd52b68a87287f60111

Metadata Standard

All Launchpad tokens follow the OpenSea metadata standard with Medialane extensions:

{
  "name": "Asset Title",
  "description": "Description of the work",
  "image": "ipfs://Qm...",
  "external_url": "https://medialane.io/asset/...",
  "attributes": [
    { "trait_type": "IP Type", "value": "Music" },
    { "trait_type": "License", "value": "CC BY 4.0" },
    { "trait_type": "Commercial Use", "value": "Allowed" },
    { "trait_type": "AI Training", "value": "Prohibited" },
    { "trait_type": "Derivative Works", "value": "Allowed with attribution" }
  ]
}

IP-specific attributes (license, commercial use, AI policy, derivative rights) are machine-readable and indexable by any compatible platform.

Gasless Minting

All Launchpad operations — collection deployment, minting, and drops — are sponsored by Medialane via the AVNU paymaster. Creators and minters need no ETH or STRK to participate. The 1% fee applies only to secondary marketplace sales, not primary minting.
