Blockchains – Ethereum, Polygon, Tezos

Each blockchain has pros and cons, when it comes to Ethereum the gas fees can be quite expensive, though despite high fees it’s the most widely used smart contract platform in 2022.

To mint an NFT on Ethereum it’s not uncommon to pay over $150 per transaction because of the inherent network fees and how the network rewards validators.

However, there are alternatives as well to Ethereum that allow transactions to be carried out with far less gas fees. One of these blockchains is the Polygon (MATIC) network, which is part of the Ethereum ecosystem, but uses a PoS consensus mechanism rather than PoW, which makes the gas fees much cheaper.

Polygon has very low fees, but is far less used and more complicated to get started with than Ethereum.

Polygon exists as an ERC-20 token on the Ethereum mainnet and as a Matic on the Polygon network.

In order to mint NFTs and benefit from low gas fees on Polygon then you have to bridge between the networks, or buy Polygon Network Matic directly, which could be difficult depending on your region and the exchanges you’re allowed to use.

Binance.com allows users to purchase Polygon Matic directly, avoiding the need to bridge.

However, if purchasing off Coinbase for example, you will have to bridge between the networks for a one-time gas fee – https://wallet.polygon.technology/

Tezos operates on an entirely different blockchain than Ethereum and Polygon. The native currency of Tezos is TEZ, also known as XTZ on apps like Coinbase.


In order to deploy to testnet with SweatyNFT, you will need to add funds to your testnet account via a faucet. A faucet is an account that sends you free ETH, MATIC or TEZ on testnet so that you can create and interact with contracts on a testnet blockchain before spending real-value currency on the mainnet blockchain.

Here are the faucets for each respective blockchain:

Polygon Mumbai Faucet – https://faucet.polygon.technology/
Tezos Hangzhounet Faucet – https://teztnets.xyz/hangzhounet-faucet
