This native interoperability powers Superchain to feel like a borderless ecosystem that is optimized for superior user experience. Also, the fusion of SuperchainERC20 + Superchain interoperability will allow for maximized capital efficiency.

Simplified deployments- <\/strong>with no liquidity pools or multiple interfaces, SuperchainERC20 requires zero infrastructure to offer cross-chain token transfers. Instead, it offers a unified interface for Superchain-compatible networks and a cross-chain common interface for the entire EVM ecosystem.<strong><br><\/strong><\/p>\n\n\n\n<p><strong>2. Permissionless propagation- <\/strong>Developers building on Superchain can quickly clone an existing token contract and utilize it for their <a href=\"https:\/\/www.zeeve.io\/appchains\/optimistic-rollups\/\" data-wpel-link=\"internal\">OP Stack Rolllups<\/a> to enable cross-chain asset transfer. This does not require them to take permission from the original owner or fulfill any other obligations.<\/p>\n\n\n\n<p><strong><br>3.

Whenever you move tokens, they are first burned (destroyed) on the source chain and minted (created) on the destination chain. Here\u2019s how the whole setup works:<br><\/p>\n\n\n\n<ul>\n<li><strong>Token Burning (source chain):<\/strong> When a user initiates transfer of token from blockchain A to blockchain B, this process starts with burning tokens on the source chain. Here\u2019s how:<br><\/li>\n<\/ul>\n\n\n\n<p><strong>Step 1:<\/strong> User adds the recipient&#8217;s wallet address on the destination chain and the amount of tokens to transfer.&nbsp;<\/p>\n\n\n\n<p><strong>Step 2:<\/strong> The equivalent amount of tokens will be burned (permanently) on the source chain.<\/p>\n\n\n\n<p><br>This process ensures that token supply remains consistent across chains and prevents duplication.<br><\/p>\n\n\n\n<ul>\n<li><strong>Token Minting (Destination chain):<\/strong> Token minting process on the destination chain involves the following steps:<br><\/li>\n<\/ul>\n\n\n\n<p><strong>Step 1: <\/strong>After verifying the burn on the source chain, the specified amount of tokens is created (minted) on the destination chain.<\/p>\n\n\n\n<p><strong>Step 2: <\/strong>The newly minted tokens are sent directly to the recipient&#8217;s wallet address, as specified during the initiation of the transfer.<\/p>\n\n\n\n<p>This will ensure that the recipient gets the tokens on the destination chain, allowing the transfer to finish while maintaining consistency in cross-chain token supply.&nbsp;<\/p>\n\n\n\n<p>Through this burn &amp; mint concept, Superchain affects only the assets on the source chain (the chain where your assets are located originally rather than impacting the overall token supply. Hence, it keeps the token amount same on all the networks while also ensuring its value remains stable during the cross-chain movement. This allows SuperchainERC20 to maintain a unified, global token supply count.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"514\" src=\"https:\/\/www.zeeve.io\/wp-content\/uploads\/2024\/12\/Superchain-80-1024x514.jpg\" alt=\"\" class=\"wp-image-78126\" srcset=\"https:\/\/www.zeeve.io\/wp-content\/uploads\/2024\/12\/Superchain-80-1024x514.jpg 1024w, https:\/\/www.zeeve.io\/wp-content\/uploads\/2024\/12\/Superchain-80-300x151.jpg 300w, https:\/\/www.zeeve.io\/wp-content\/uploads\/2024\/12\/Superchain-80-768x385.jpg 768w, https:\/\/www.zeeve.io\/wp-content\/uploads\/2024\/12\/Superchain-80.jpg 1026w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>The above diagram has illustrated the whole process of SuperchainERC20, where tokens are getting burned on chain A (source chain) and minted on chain B (destination chain) for smoothing cross-chain transfers without needing asset wraps or a liquidity pool.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-steps-to-implement-superchainerc20-standard\"><strong>Steps to implement SuperchainERC20 Standard<\/strong><\/h2>\n\n\n\n<p>Implementing SuperchainERC20 standard ensures that your tokens will benefit from cross-chain interoperability element once the interop upgrade goes live on Superchain.

DeFi applications:<\/strong> SuperchainERC20 enables real-time cross-chain DeFi for all the involved chains. This allows users to stake tokens on chain A and simultaneously use the same tokens as collateral for borrowing on chain B.
