{"id":"polygon-bridged-wbtc-polygon-pos","title":"Polygon Bridged WBTC (Polygon POS)","content":"**Polygon Bridged WBTC (Polygon POS)** is a token designed to facilitate the transfer of Wrapped [Bitcoin](https://iq.wiki/wiki/bitcoin) (WBTC) between the [Ethereum](https://iq.wiki/wiki/ethereum) and [Polygon](https://iq.wiki/wiki/polygon) networks. It functions as a pegged token, aiming to maintain a 1:1 value with WBTC on the Polygon [blockchain](https://iq.wiki/wiki/blockchain). This allows users to utilize [Bitcoin](https://iq.wiki/wiki/bitcoin)'s value within the Polygon ecosystem's [decentralized finance](https://iq.wiki/wiki/defi) (DeFi) applications and other protocols.\n\n## Overview\n\nPolygon Bridged WBTC (Polygon [POS](https://iq.wiki/wiki/proof-of-stake)) represents Wrapped Bitcoin ([WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc)) that has been transferred from the [Ethereum](https://iq.wiki/wiki/ethereum) network to the [Polygon](https://iq.wiki/wiki/polygon) network via a bridging mechanism. The primary purpose of this token is to enable the use of [Bitcoin](https://iq.wiki/wiki/bitcoin)'s liquidity and value within the Polygon ecosystem, which is known for its lower transaction fees and faster processing speeds compared to the Ethereum mainnet. By bridging WBTC, users can participate in Polygon-based [DeFi](https://iq.wiki/wiki/defi) activities such as lending, borrowing, and trading on decentralized exchanges without needing to convert their Bitcoin into other native Polygon assets. The token is listed on various [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) data platforms, where its price and market statistics are tracked. As of July 2025, it holds a [market capitalization](https://iq.wiki/wiki/market-capitalization) of over $330 million and is ranked among the top 250 cryptocurrencies by market cap.

The process typically involves locking an amount of WBTC on the Ethereum blockchain. Once the [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) is locked on Ethereum, an equivalent amount of Polygon Bridged WBTC ([WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc)) is minted on the Polygon [blockchain](https://iq.wiki/wiki/blockchain). This mechanism ensures that the total supply of WBTC across both chains remains consistent, with the bridged tokens on Polygon being backed 1:1 by the locked WBTC on Ethereum. When a user wishes to move their WBTC back to the Ethereum network, the Polygon Bridged WBTC is [burned](https://iq.wiki/wiki/token-burn) on Polygon, and the corresponding WBTC is unlocked on Ethereum. This lock-and-mint and burn-and-release process is fundamental to maintaining the peg between the bridged asset and its underlying asset. [\\[1\\]](#cite-id-kPsfviNqJM)\n\n## Tokenomics\n\nThe [tokenomics](https://iq.wiki/wiki/tokenomics) of Polygon Bridged WBTC (Polygon [POS](https://iq.wiki/wiki/proof-of-stake)) are directly tied to the supply of [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) that has been bridged onto the [Polygon](https://iq.wiki/wiki/polygon) network. The [circulating supply](https://iq.wiki/wiki/circulating-supply) of Polygon Bridged WBTC represents the amount of WBTC currently active and usable within the Polygon ecosystem. The total supply reflects the cumulative amount of WBTC that has been minted on Polygon. Because it is a pegged token representing an asset locked on another chain, its supply on Polygon is dependent on the bridging activity. The maximum supply is often listed as infinite, as there is no hard cap on how much WBTC can theoretically be bridged, limited only by the total supply of WBTC itself. The market capitalization is calculated by multiplying the current price of the token by its circulating supply. The fully diluted valuation (FDV) is the theoretical [market cap](https://iq.wiki/wiki/market-capitalization) if the total supply were in circulation, which in the case of a 1:1 pegged token like this, is typically equal to the market cap when the circulating supply equals the total supply. As of July 2025, the circulating and total supply were approximately 3,034 tokens, resulting in a market cap and FDV around $337 million.

These platforms allow users to swap WBTC for other [cryptocurrencies](https://iq.wiki/wiki/cryptocurrency) and stablecoins available within the Polygon ecosystem. Some of the prominent decentralized exchanges where [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) can be traded include [Uniswap](https://iq.wiki/wiki/uniswap) V3 (Polygon), [Quickswap](https://iq.wiki/wiki/quickswap) (v3), and Uniswap V4 (Polygon). Trading pairs often involve [stablecoins](https://iq.wiki/wiki/stablecoin) like [USDC](https://iq.wiki/wiki/usdc).E and USDC, as well as wrapped [Ethereum](https://iq.wiki/wiki/ethereum) ([WETH](https://iq.wiki/wiki/weth-wrapped-eth)). The daily trading volume for Polygon Bridged WBTC fluctuates, reflecting the level of activity and liquidity on these decentralized exchanges. The price of Polygon Bridged WBTC is typically closely pegged to the price of WBTC and [Bitcoin](https://iq.wiki/wiki/bitcoin), with minor variations due to market dynamics and bridging costs.

Similar bridged versions of [WBTC](https://iq.wiki/wiki/wrapped-bitcoin-wbtc) exist on other blockchain ecosystems, allowing users to transfer Bitcoin's value to those networks. Examples include Arbitrum Bridged WBTC ([Arbitrum](https://iq.wiki/wiki/arbitrum) One), Optimism Bridged WBTC ([Optimism](https://iq.wiki/wiki/optimism)), Cronos Bridged WBTC ([Cronos](https://iq.wiki/wiki/cronos-cro)), and Avalanche Bridged WBTC ([Avalanche](https://iq.wiki/wiki/avalanche)). These tokens serve a similar function within their respective ecosystems, enabling cross-chain transfers and participation in [DeFi](https://iq.wiki/wiki/defi) activities on those networks using a [Bitcoin](https://iq.wiki/wiki/bitcoin)-pegged asset.
