Freeze metadata in IPFS

Job ID: 33001563

Budget: $30 – $250 USD

I’m looking for a IPFS developer with Opensea experience. I need to freeze the metadata of the NFT collection (json file) before uploading on Opensea via BOT. The smart contract and token (ERC-1155) is created by a Opensea by lazy minting.

The Opensea freeze metadata function is to expensive with individual gas fees to be paid.

Looking for someone with strong experience in IPFS and Opensea.
