NFTs on Polygon: fastest, cheapest ETH to WETH bridging

Umbria Network’s Narni liquidity bridge removes the difficulty and expense of moving assets between blockchains and is the fastest and cheapest cross-chain liquidity bridge between the Ethereum and Polygon networks.

NFT project partnerships

We’re delighted to be introducing our Narni cross-chain liquidity bridge to a wider NFT audience via collaborations with innovative projects that are minting and selling on the Polygon blockchain.

When buying NFTs on a Polygon marketplace such as OpenSea, users must bridge their Ether (ETH) to Polygon ETH, known as Wrapped ETH (WETH). The Narni bridge facilitates this cross-chain transaction substantially faster and cheaper than similar bridges. It typically takes less than four minutes and often costs just $4-$9 to transfer assets from the Ethereum to the Polygon network.

We’re pleased to announce our second phase of NFT partnerships. The following projects endorse the Narni Bridge and promote it to their communities as the fastest and cheapest method for bridging crypto.

Frontyard Baseball

Frontyard Baseball is a P2E gaming NFT with a focus on giving back to youth sports programs within communities. There are only 25,000 players available each with their own special attributes. $125,000 will be donated through the minting process to an underprivileged youth sports charity of the community’s choosing. 50% of all royalties on OpenSea will go to the same charity. After the sellout, Frontyard Baseball will be giving away a Tesla to a random holder in the community. Its gameplay is a 9v9 simulated baseball game to play against your NFT friends.

Friday Night Punks

Friday Night Punks is a fun hand-made pixelated NFT collection of the best American Football players. These unique NFTs are limited edition punks of favorite players, teams and eras. All punks have different rarity: Star, Superstar or Legend.

They’re aimed at fans of American Football and fans of the hugely popular CryptoPunks NFT collection.

Beluga Bay

Beluga Bay is a project of 12,000 whales in six fun collections. Because we chose Polygon, we are able to do fun activities with our NFTs like land ownership inside Beluga Bay, breeding, and questing. In addition to our fun project, Beluga Bay Foundation hosts a Polygon NFT Community and Projects Twitter Spaces daily from 2–4 PM EST featuring 500+ NFT projects that have migrated to Polygon. In early December, Beluga Bay was rewarded with an exciting grant opportunity that will cover the infrastructure needed to build a community-based polygon-specific ecosystem. Beluga Bay is involved with various charity organizations focused on cancer and ocean cleanup. We are very happy to be partnered with Umbria for all of our bridging needs.


PolyChainPunks are 8,888 left facing punks that live on the Polygon Chain. The Human species lived peacefully until the Alien faction invaded. The 3 Alien factions are the Greens, they are mostly neutral and peace loving, the Blues were just and loyal and in charge of keeping the order; then there are the Reds, the violent, warmonger faction.

Will the PolyChainPunks and Aliens learn to live in harmony? Will there be war in the Polygon Chain? Find out for yourself, own a Season 1 PolyChainPunk for a spot on Season 2.
