{"id":"wrapped-bnb-wbnb","title":"Wrapped BNB (WBNB)","content":"**Wrapped BNB (WBNB)** is a tokenized version of [Binance](https://iq.wiki/wiki/binance) Coin ([BNB](https://iq.wiki/wiki/binance-coin)) on the [BNB Smart Chain](https://iq.wiki/wiki/binance-smart-chain) (BSC) that conforms to the [BEP-20](https://iq.wiki/wiki/bep-20) standard. Its primary purpose is to enable BNB to be used within [decentralized applications](https://iq.wiki/wiki/decentralized-application) (dApps) and [decentralized finance](https://iq.wiki/wiki/defi) (DeFi) protocols on the BSC network.\n\n## Overview\n\n$$widget0 [YOUTUBE@VID](https://youtube.com/watch?v=BPNBbbqvTIk)$$\n\nWrapped BNB functions as a wrapped token, meaning its value is pegged 1:1 to the value of the underlying asset, which in this case is BNB. This wrapping process makes [BNB](https://iq.wiki/wiki/binance-coin) compatible with the [BEP-20](https://iq.wiki/wiki/bep-20) token standard used on the [BNB Smart Chain](https://iq.wiki/wiki/binance-smart-chain), allowing it to interact with smart contracts and participate in activities like trading on [decentralized exchanges](https://iq.wiki/wiki/decentralized-exchange) (DEXs), [yield farming](https://iq.wiki/wiki/yield-farming), and lending protocols.\n\nThe creation of WBNB addresses the limitation of the native [BNB](https://iq.wiki/wiki/binance-coin) token, which was initially designed primarily for use on the [Binance](https://iq.wiki/wiki/binance) Chain for trading and exchange functions. By wrapping BNB into WBNB, its liquidity can be utilized [across](https://iq.wiki/wiki/across) different [blockchains](https://iq.wiki/wiki/blockchain) and within the BSC ecosystem's [DeFi](https://iq.wiki/wiki/defi) applications. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[2\\]](#cite-id-0gElebEdr3) [\\[3\\]](#cite-id-3SzLZtsgkc) [\\[4\\]](#cite-id-Luen8RteOm) [\\[5\\]](#cite-id-WrkTLRcpl1) [\\[6\\]](#cite-id-ufd1nqTBkl) [\\[7\\]](#cite-id-UYFOZvgt70)\n\n## History\n\nWrapped BNB was introduced as part of the [Binance](https://iq.wiki/wiki/binance) platform's expansion, particularly with the launch of the [Binance](https://iq.wiki/wiki/binance) Smart Chain (later rebranded to BNB Smart Chain) in September 2020. The concept was announced by [Changpeng Zhao](https://iq.wiki/wiki/changpeng-zhao), the founder and CEO of [Binance](https://iq.wiki/wiki/binance). The development aimed to enhance the functionality of [BNB](https://iq.wiki/wiki/binance-coin) beyond simple [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) trading and enable its use in the growing [DeFi](https://iq.wiki/wiki/defi) space on BSC. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[2\\]](#cite-id-0gElebEdr3)\n\n## Technology\n\nWBNB operates on the BNB Smart Chain and adheres to the [BEP-20](https://iq.wiki/wiki/bep-20) token standard. The BEP-20 standard is a technical specification for tokens on BSC, similar to [Ethereum's](https://iq.wiki/wiki/ethereum) [ERC-20](https://iq.wiki/wiki/erc-20) standard, which defines how tokens are spent, how they are authorized to be spent by another contract, and how they interact with other tokens and [dApps](https://iq.wiki/wiki/decentralized-application).\n\nThe process of converting [BNB](https://iq.wiki/wiki/binance-coin) to WBNB is known as \"wrapping,\" and converting WBNB back to BNB is called \"unwrapping\" or \"redeeming\". This conversion typically involves using a bridge service or a [smart contract](https://iq.wiki/wiki/smart-contract) that locks the original BNB on the native chain and issues an equivalent amount of WBNB on the BNB Smart Chain. Custodians, which can be smart contracts or multi-signature wallets, are involved in managing the locked assets. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[2\\]](#cite-id-0gElebEdr3) [\\[3\\]](#cite-id-3SzLZtsgkc) [\\[4\\]](#cite-id-Luen8RteOm) [\\[5\\]](#cite-id-WrkTLRcpl1) [\\[6\\]](#cite-id-ufd1nqTBkl) [\\[7\\]](#cite-id-UYFOZvgt70)\n\n## Use Cases\n\nWBNB serves several key functions within the BNB Smart Chain ecosystem and beyond:\n\n* **DeFi Participation:** WBNB allows users to engage with various [DeFi](https://iq.wiki/wiki/defi) protocols on BSC, including [decentralized exchanges](https://iq.wiki/wiki/decentralized-exchange) (DEXs) like [PancakeSwap](https://iq.wiki/wiki/pancakeswap), lending platforms like [Venus](https://iq.wiki/wiki/venus-protocol) and [Aave](https://iq.wiki/wiki/aave), and [yield farming](https://iq.wiki/wiki/yield-farming) applications.

[\\[1\\]](#cite-id-NCZaehSOtx) [\\[2\\]](#cite-id-0gElebEdr3) [\\[5\\]](#cite-id-WrkTLRcpl1) [\\[6\\]](#cite-id-ufd1nqTBkl)\n* **Liquidity Provision:** WBNB is used in [liquidity pools](https://iq.wiki/wiki/liquidity-pool) on [DEXs](https://iq.wiki/wiki/decentralized-exchange), allowing users to earn fees by providing WBNB and other tokens for trading pairs. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[4\\]](#cite-id-Luen8RteOm) [\\[6\\]](#cite-id-ufd1nqTBkl)\n* **Smart Contract Interaction:** As a BEP-20 token, WBNB can interact with complex smart contracts, enabling its use in a wide range of dApps. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[4\\]](#cite-id-Luen8RteOm)\n* **Developer Use:** Developers can utilize WBNB when building protocols, digital assets, and NFTs on the BNB Smart Chain. [\\[1\\]](#cite-id-NCZaehSOtx)\n\nThe wrapping of BNB into WBNB offers several benefits:\n\n* **Interoperability:** Enables the use of [BNB's](https://iq.wiki/wiki/binance-coin) value on [blockchain](https://iq.wiki/wiki/blockchain) networks other than its native chain, particularly within the BNB Smart Chain ecosystem. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[2\\]](#cite-id-0gElebEdr3) [\\[4\\]](#cite-id-Luen8RteOm) [\\[5\\]](#cite-id-WrkTLRcpl1) [\\[6\\]](#cite-id-ufd1nqTBkl)\n* **DeFi Access:** Provides access to the diverse range of [DeFi](https://iq.wiki/wiki/defi) applications and services available on BSC. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[4\\]](#cite-id-Luen8RteOm) [\\[5\\]](#cite-id-WrkTLRcpl1) [\\[6\\]](#cite-id-ufd1nqTBkl)\n* **Ease of Conversion:** The process of exchanging [BNB](https://iq.wiki/wiki/binance-coin) for WBNB and vice versa is designed to be straightforward and quick. [\\[1\\]](#cite-id-NCZaehSOtx) [\\[4\\]](#cite-id-Luen8RteOm) [\\[5\\]](#cite-id-WrkTLRcpl1) [\\[3\\]](#cite-id-3SzLZtsgkc)\n* **Cost-Effectiveness (for large transactions):** While wrapping/unwrapping incurs [gas](https://iq.wiki/wiki/gas) fees, using WBNB for transactions within BSC can be more cost-effective than transacting the native asset on its original, potentially more expensive, network for certain use cases. [\\[2\\]](#cite-id-0gElebEdr3)\n* **Enhanced Security (via private key control):** Once wrapped, the user controls the private key for the WBNB token, which is separate from the native BNB asset held by the custodian. [\\[2\\]](#cite-id-0gElebEdr3)\n\n## Team\n\nWrapped BNB was created in connection with the [Binance](https://iq.wiki/wiki/binance) platform, which was founded by [Changpeng Zhao](https://iq.wiki/wiki/changpeng-zhao). Changpeng Zhao is a Chinese-Canadian entrepreneur known as the founder and CEO of [Binance](https://iq.wiki/wiki/binance).
