ULTRA EVM TESTNET · CHAIN ID 18881
Testnet deployment checks
Verify that your funded MetaMask account is on the real Ultra EVM Testnet. Run a harmless, user-approved transaction to check Cancun smart-contract compatibility before attempting the owner-only NFT factory. This page never connects to mainnet.
1. Verify your wallet and funds
Funded account for this test: 0xB2b3…5942. The existing LookeNFT publishing administrator uses a different wallet (0xb7f8…ad98). Check which wallet MetaMask is actually connected to.

2. Prove Cancun opcode compatibility
This small wallet-approved transaction deploys only a smoke-test contract. It uses PUSH0 and MCOPY and returns 42 when called. It cannot transfer tokens, mint NFTs, or control LookeNFT.
This creates a real Testnet contract, so your wallet will ask you to approve a gas fee in test UOS. No transaction is sent automatically. It is not an audit or a factory deployment.
3. Owner-only NFT factory and free mint
The remaining actions must occur on **Ultra EVM Testnet**, one signed wallet transaction at a time: verify and deploy the owner-only factory, pin real artwork/metadata, deploy a 10,000-cap ERC-721 collection, schedule a 0 UOS mint phase, test minting from a second wallet, and verify receipts and ownership.
Deployment and public minting remain disabled until actual chain proofs and owner approval exist. A funded wallet does not automatically replace the existing administrator or authorize mainnet activity. No unverified collections or NFTs will be fabricated.
