opBNB: dApps, Airdrops and Everything You Need to Know
BNB Chain announced the launch of opBNB, a Layer 2 scaling solution with several dApps and projects announcing they’re building on opBNB. We take a deeper dive into the 9 dApps that are on opBNB Mainnet with several other dApps to follow suit (currently in the testnet phase).
All Layer 1 blockchains face the same dilemma: what to do when you need to scale? Rollups and Layer 2 blockchains emerged as viable scaling solutions by reducing the cost of transactions, increasing transaction speed, and processing a higher number of transactions. As we enter the era of Layer 2 blockchains, social dApps, gaming dApps, and tooling dApps can expect to benefit from the advantages of using a Layer 2 blockchain.
What is opBNB?
opBNB is a Layer-2 scaling solution built on an open-source codebase called the OP Stack. opBNB lowers high transaction costs and network congestion by processing 4000 TPS (transactions per second) while bringing gas fees down to $0.005 per transaction.
opBNB mainnet was launched on 13 September 2023, less than 2 weeks after BNB Chain celebrated its 3rd anniversary. Before launch, opBNB was in the testnet phase with participants eligible for a Genesis NFT and BNB airdrop.
How does opBNB work?
opBNB processes transactions off-chain which are then posted back onto the Layer 1 (i.e. BNB Chain) blockchain as call data. By processing transactions off-chain, opBNB enables more transactions at a lower cost (in gas fees).
Some of the advantages of opBNB include:
- Higher transaction speed compared to L1
- Lower transaction cost (gas fees) compared to L1
- Use of L1 ecosystem assets (such as BNB for gas)
- Monetary and non-monetary support for builders and developers
L2 Gas Fees
opBNB has the lowest fees when comparing the gas fees of transactions of some of the most used Layer 2 blockchains. The average gas fee of a transaction on opBNB is $0.005 while the average gas fee of a transaction on BSC, Starknet, BASE, Arbitrum, Linea, Polygon zkEVM, and zkSync is between $0.01 to $0.1.
9 opBNB Mainnet dApps
The 9 opBNB dApps covered in this topic include all the opBNB dApps listed on DappBay that have also launched on opBNB Mainnet. Check here for the full list of dApps currently in testnet and/or in mainnet.
Out of the 9 opBNB dApps, 5 dApps belong to the tools and utility category, 3 dApps to the DeFi category, and 1 dApp to the gaming category. The list of dApps is listed in alphabetical order and includes Alltoscan, AltLayer, BurgerCities, Cielo, DATS, DeCommas, Krystal, Pulsar Finance, and zkLink.
Alltoscan is a multichain blockchain explorer and analytics platform where Web3 users can search for blockchain information by address, transaction, or block. The domain name search feature allows users to interact with other addresses on-chain using human-readable names instead of long and complicated address hashes.
AltLayer is an open and decentralized interlayer for rollups. The AltLayer protocol consists of a core network (the Beacon Layer) that acts as an interlayer between rollups and their respective data availability or settlement layers. AltLayer offers a versatile, no-code Rollups-as-a-Service (RaaS) launchpad that allows not only developers but also those with little to no coding experience to spin up a customized rollup within 2 minutes.
BurgerCities is a one-stop MetaFi platform with a wide range of features, a DEX, and an NFT made of Heroes, Props, and Lands. BurgerCities “evolved” from Burgerswap, a DeFi product on BNB Chain. Users can participate in daily activities like socializing and playing games, as well as experience DeFi and NFT features with their avatars like trading, staking, NFT exhibitions, etc.
Cielo is a human-readable information layer for Web3 and helps users answer questions such as who, how, where, and why. It allows anyone to create a real-time feed of on-chain activity and filter it by transaction type, chain, and size. Cielo is used for deciphering on-chain transactions such as tracking hedge funds, monitoring own wallets, or discerning a DeFi trend.
DATS is a blockchain company that produces automated vulnerability scanning and cybersecurity solutions with distributed high computing power for Web3, Web2, and blockchain security. DATS develops high-performance computing-integrated SaaS solutions that aim to increase the resilience of projects and Web2 institutions in the Blockchain ecosystem against increasingly sophisticated cyber attacks around the world and eliminate many problems in the cybersecurity industry.
