# Welcome to Corridor.Finance ## TL;DR Corridor Finance is building cross chain Bitcoin Defi platform, including cross chain AMM swap, bridge & farming tools. Corridor Finance is the first cross-chain AMM Swap for all Bitcoin L2 networks. You can swap between BRC20, CBRC20, Tap, Runes at one swap and Corridor provides the opportunities to provide liquidity across different Bitcoin L2. ## Overview Corridor Finance is aspiring to construct the definitive gateway enabling the flourishing of Bitcoin-based assets on EVM L2 networks, including, BNB, Polygon, Optimism, Arbitrum, BASE, and beyond. Corridor Bridge aims to create a robust, efficient bridge mechanism that facilitates undisturbed token transfers between the Ethereum chain, Bitcoin network, and other relevant chains. By connecting the strengths of ERC20 tokens with Bitcoin-based assets, Corridor Bridge boosts the liquidity of such assets while fostering the expansion and progression of the holistic Bitcoin ecosystem. ## Why BRC20 The BRC-20 token standard is a prototype standard that utilizes ordinal inscriptions to facilitate the creation and transference of interchangeable tokens on the Bitcoin blockchain. This BRC-20 token standard bears resemblance to the ERC-20 token standard that operates on Ethereum and EVM blockchain networks. > An experiment into "brc-20's" and fungibility on bitcoin with ordinals 1/x [pic.twitter.com/9khKLbEPk6](https://t.co/9khKLbEPk6) > > — domo (@domodata) [March 9, 2023](https://twitter.com/domodata/status/1633658974686855168?ref_src=twsrc%5Etfw) Contrary to the Bitcoin blockchain's original design, BRC-20 operates in conjunction with the Bitcoin currency on the Bitcoin network, similar to the way smart contract tokens function on the Ethereum blockchain. BRC-20 tokens come into existence by connecting a JSON to satoshis via Bitcoin ordinals. This JSON code segment specifies every feature of the BRC-20 token, encompassing factors such as minting and distribution. The Bitcoin network deciphers this information once the tokens are deployed. Much like conventional tokens, BRC-20 tokens are minted and used. To create BRC-20 tokens, a Bitcoin ordinal wallet is necessary, and there's a specific limit for each minting process. The BRC-20 token standard has earned widespread recognition, with its market capitalization exceeding $600 million and multiple thousands of BRC-20 tokens already being minted. Some notable BRC-20 tokens are the Ordinal token (ORDI) and OXBT. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
