How to use Rarible for cross-chain NFT minting? (Multi-chain)

Cross-Chain NFT Minting on Rarible

1. Rarible supports multi-chain NFT creation through its decentralized protocol layer, enabling users to deploy smart contracts on Ethereum, Polygon, Solana, and Tezos without switching platforms. The interface detects wallet network automatically upon connection, allowing immediate selection of target chain before minting.

2. Users must hold native gas tokens for the selected chain—ETH for Ethereum, MATIC for Polygon, SOL for Solana, XTZ for Tezos—to cover transaction fees during contract deployment and tokenization. Wallets like MetaMask, Phantom, and Temple are natively integrated depending on chain compatibility.

3. During the minting flow, Rarible displays real-time gas estimates per chain, including base fee, priority tip (Ethereum/Polygon), and validator fee (Solana). These values update dynamically based on current network congestion and are shown in both native token and USD equivalents.

4. Each chain uses a distinct standard: ERC-721 or ERC-1155 on Ethereum and Polygon, SPL-token-based NFTs on Solana, and FA2 tokens on Tezos. Rarible abstracts these differences into a unified metadata input form but enforces chain-specific validation rules before finalizing the transaction.

5. After confirmation, the NFT is recorded on the chosen blockchain’s ledger. Rarible’s indexer then synchronizes the asset across its frontend, making it instantly visible in the user’s profile under the corresponding chain tab. No manual cross-chain bridging is required at mint time.

Wallet Configuration for Multi-Chain Support

1. MetaMask users must manually add Polygon and Ethereum testnets via custom RPC settings before accessing those chains on Rarible. Default Mainnet configuration only enables Ethereum unless additional networks are imported.

2. Phantom wallet auto-detects Solana Mainnet Beta and Devnet. Switching between them requires toggling inside Phantom’s network selector, which propagates to Rarible’s active context without page reload.

3. Temple wallet handles Tezos network switching via dropdown in its extension UI. Rarible reads this selection and adjusts signing methods accordingly—baking-aware signatures for Mainnet, sandbox-compatible ones for Ghostnet.

4. Wallet address reuse across chains is permitted but discouraged. Rarible does not enforce unique addresses per chain, yet some marketplaces reject listings from reused addresses due to signature replay concerns on certain consensus layers.

Metadata Handling Across Chains

1. Rarible accepts centralized or decentralized storage options for NFT metadata: IPFS via Pinata or Filecoin, Arweave, or HTTP endpoints. All chains use the same JSON schema regardless of underlying blockchain.

2. On-chain metadata embedding is disabled by default. Only Solana permits optional on-chain metadata via compressed NFTs (cNFTs) using Bubblegum program; Rarible exposes this toggle only when Solana is selected.

3. Metadata URI generation follows EIP-3906 conventions for Ethereum/Polygon, Metaplex standard for Solana, and TZIP-16 for Tezos. Rarible validates URIs against each chain’s expected format prior to submission.

4. Preview rendering in the minting interface adapts to chain-specific limitations—animated GIFs render as static previews on Tezos due to FA2 renderer constraints, while Solana supports full MP4 playback in listing cards.

Fees and Royalty Enforcement

1. Platform fee is fixed at 2.5% of primary sale value and deducted in the native token of the sale chain. This fee is enforced at settlement time, not minting, and applies uniformly across all supported blockchains.

2. Creator royalties are encoded in-chain using each ecosystem’s native mechanism: Seaport hooks on Ethereum, marketplace-agnostic royalty registry on Polygon, Metaplex Token Metadata Program on Solana, and TZIP-21-compliant registry on Tezos.

3. Gas costs vary significantly: Ethereum mainnet minting averages $12–$45, Polygon stays below $0.03, Solana hovers near $0.00025, and Tezos ranges from $0.08 to $0.15. These figures reflect actual broadcast costs, not estimated simulation values.

4. Rarible does not subsidize gas for any chain. Third-party relayer services like Biconomy or Gelato are unsupported in the official minting flow, requiring users to manage their own transaction funding.

Common Questions

Q: Can I mint the same NFT on multiple chains simultaneously?Yes. Rarible allows batch minting across up to four chains in one session. Each mint generates a separate token ID and contract address, with no automatic linkage between versions.

Q: Does Rarible support wrapped assets like wETH or renBTC as payment for royalties?No. Royalty payouts occur exclusively in the native token of the chain where the sale occurred—ETH for Ethereum, MATIC for Polygon, SOL for Solana, XTZ for Tezos.

Q: Are there restrictions on file types for cross-chain uploads?Rarible accepts PNG, JPG, GIF, MP4, WEBM, GLB, and SVG universally. Audio formats like MP3 and WAV are accepted only on Ethereum, Polygon, and Tezos—not Solana, due to Metaplex’s current audio handling limitations.

Q: How does Rarible verify ownership when transferring NFTs between chains?Rarible does not perform cross-chain transfers. Inter-chain movement requires external bridges or marketplaces supporting atomic swaps. Ownership verification remains chain-local and never crosses consensus boundaries within Rarible’s infrastructure.
