{"id":"arbitrum-bridged-wbtc","title":"Arbitrum Bridged WBTC","content":"**Arbitrum Bridged WBTC (Arbitrum One)** is a representation of [Wrapped Bitcoin](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) (WBTC) on the Arbitrum One network, allowing users to utilize [Bitcoin](https://iq.wiki/wiki/bitcoin)'s value within the [Arbitrum](https://iq.wiki/wiki/arbitrum) ecosystem. It functions as an [ERC-20](https://iq.wiki/wiki/erc-20) token pegged 1:1 to WBTC, enabling faster and lower-cost transactions compared to the [Ethereum](https://iq.wiki/wiki/ethereum) [mainnet](https://iq.wiki/wiki/mainnet).\n\n## Overview\n\n[Wrapped Bitcoin](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) (WBTC) is an [ERC-20](https://iq.wiki/wiki/erc-20) token on the [Ethereum](https://iq.wiki/wiki/ethereum) [blockchain](https://iq.wiki/wiki/blockchain) that is backed 1:1 by [Bitcoin](https://iq.wiki/wiki/bitcoin) (BTC). Its creation allows Bitcoin holders to participate in [decentralized finance](https://iq.wiki/wiki/defi) (DeFi) applications and smart contracts predominantly built on Ethereum. Arbitrum Bridged WBTC extends this functionality by making WBTC available on [Arbitrum](https://iq.wiki/wiki/arbitrum) One, a [Layer 2](https://iq.wiki/wiki/layer-2) scaling solution for Ethereum.\n\nThe primary purpose of bridging [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) to Arbitrum One is to leverage [Arbitrum](https://iq.wiki/wiki/arbitrum)'s architecture for increased transaction speed and reduced [gas](https://iq.wiki/wiki/gas) fees. Users can deposit WBTC from the [Ethereum](https://iq.wiki/wiki/ethereum) [mainnet](https://iq.wiki/wiki/mainnet) onto Arbitrum One via a bridge, receiving Arbitrum Bridged WBTC in return. This bridged asset can then be used within the Arbitrum ecosystem for various activities, such as trading on [decentralized exchanges](https://iq.wiki/wiki/decentralized-exchange) (DEXs), particip ating in lending protocols, and engaging with other [DeFi](https://iq.wiki/wiki/defi) applications.\n\nThe process of moving assets between the [Ethereum](https://iq.wiki/wiki/ethereum) [mainnet](https://iq.wiki/wiki/mainnet) and Arbitrum One involves a bridging mechanism. For [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc), this means locking the asset on one chain and minting an equivalent representation on the other. Arbitrum's bridge facilitates this transfer, allowing users to move their WBTC value between the high-security environment of Ethereum [Layer 1](https://iq.wiki/wiki/layer-1) and the scalable environment of [Arbitrum](https://iq.wiki/wiki/arbitrum) [Layer 2](https://iq.wiki/wiki/layer-2). [\\[1\\]](#cite-id-b55mnLEnyd) [\\[3\\]](#cite-id-4F3VqtJHQL) [\\[5\\]](#cite-id-l1lPG7QEE8) [\\[7\\]](#cite-id-vdktrEKc32) [\\[8\\]](#cite-id-uifUbnTroN)\n\n## Technology\n\nArbitrum Bridged WBTC operates as an [ERC-20](https://iq.wiki/wiki/erc-20) token on the Arbitrum One network. The underlying technology relies on a cross-chain bridge that connects the Ethereum [mainnet](https://iq.wiki/wiki/mainnet) and Arbitrum One. When a user wants to move [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) from [Ethereum](https://iq.wiki/wiki/ethereum) to [Arbitrum](https://iq.wiki/wiki/arbitrum), they interact with the bridge contract on Ethereum, locking their WBTC. The bridge then communicates with the Arbitrum One network to mint an equivalent amount of Arbitrum Bridged WBTC tokens to the user's address on Arbitrum.\n\nConversely, to move Arbitrum Bridged WBTC back to the [Ethereum](https://iq.wiki/wiki/ethereum) [mainnet](https://iq.wiki/wiki/mainnet), a user initiates a withdrawal via the bridge on Arbitrum One. This process typically involves [burning](https://iq.wiki/wiki/token-burn) the Arbitrum Bridged WBTC tokens on [Layer 2](https://iq.wiki/wiki/layer-2), which signals the bridge to release the corresponding [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) locked on the Ethereum mainnet. Arbitrum One utilizes optimistic [rollup](https://iq.wiki/wiki/rollup) technology, which processes transactions off-chain and posts compressed transaction data to the Ethereum mainnet, relying on a dispute resolution period to ensure correctness. Bridging assets like WBTC leverages this Layer 2 architecture for efficiency. Cross-chain bridges, such as those utilizing aggregators like Li.Fi, facilitate the transfer of WBTC between different [blockchain](https://iq.wiki/wiki/blockchain) networks, including [Arbitrum](https://iq.wiki/wiki/arbitrum), Ethereum, [Polygon](https://iq.wiki/wiki/polygon), and others.

The supply of Arbitrum Bridged WBTC is dynamic, depending on the amount of WBTC that has been bridged onto the Arbitrum One network.\n\nAs of June 17, 2025, the circulating supply of Arbitrum Bridged WBTC (Arbitrum One) is approximately 8,172 tokens. The total supply is also reported as 8,172 tokens, indicating that the [circulating supply](https://iq.wiki/wiki/circulating-supply) represents the entire amount currently on the Arbitrum One network. The maximum supply is listed as infinite, reflecting that the supply is limited only by the amount of [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) that can be bridged onto Arbitrum One.\n\nThe [market capitalization](https://iq.wiki/wiki/market-capitalization) of Arbitrum Bridged WBTC (Arbitrum One) is calculated by multiplying its current price by its [circulating supply](https://iq.wiki/wiki/circulating-supply). The fully diluted valuation (FDV) is the same as the market cap, given that the total supply is currently equal to the circulating supply.
