Deployment Addresses

Reference for current deployments of 0xEssential cross-chain token-gating infrastructure

0xEssential's EssentialForwarding contract is deployed on Polygon's Matic mainnet and Mumbai testnet. Developers are free to fork this code and deploy to other networks. 0xEssential also plans to support other networks in the future.

This means that today, you can deploy contracts to Polygon's POS network that utilize cross-chain token gating.

These contracts can depend on token ownership from any EVM chain. Of course there's not much sense in using it for Polygon NFTs - it's a lot simpler to directly look up ownership in your contract.

Ownership RPC API

0xEssential offers a deployed version of our Ownership RPC API. This production environment supports looking up NFT ownership from any EVM chain test or mainnet as long as the ERC721 contract is spec compliant.

Developers are instilling some trust in 0xEssential by using our centralized deployment. You're free to clone our code and deploy your own, but you must also then deploy your own version of EssentialForwarder to include your deployment URL in the error params.

If you use our deployed forwarder you will automatically be using our Ownership RPC API deployed at https://middleware.nfight.xyz
