A few days ago, I concluded my set of Masterclasses named Crafting CCIP. The journey explains how the Chainlink Cross Chain Interoperability Protocol works and how we can build Cross-Chain Decentralized Apps (CC-DAPPS). These are the new types of DApps that will revolutionize the market by transferring value from one chain to another. Inspired by this, I had the idea 💡 to develop a simple Custom Cross-Chain ERC20 token. The distinctive feature of this token is that it enables the seamless flow of value between different chains.

Understanding Cross-Chain Tokens
Nowadays, blockchains are like isolated islands in the middle of the ocean. Assets of one chain can freely flow just into its network. A Custom Cross-Chain Fungible Token breaks through this wall. This opens the door to move value from one chain to another one in a safe way, increasing the usability of the token and improving the user experience for Web3 users.
CCIP's Token Types
Chainlink CCIP features two types of token categories:
CCIP-BnM (Burn and Mint):
This type of token utilizes the Burn and Mint handling mechanism for transfer. Source chains burn the specified amount of tokens for transfer, and the destination chains mint an equivalent amount in the receiver's address.
CCIP-LnM (Lock and Mint):
Tokens in this category are locked on the source chain within Token Pools. Wrapped, synthetic, or derivative tokens representing the locked tokens are then minted on the destination chain.
To the purpose of this article, we will cover the LnM (Lock and Mint) handling mechanism.
Use Cases and Applications
The implementation of LnM Custom Cross-Chain ERC20 tokens unlocks diverse use cases and applications within the decentralized ecosystem:
Decentralized Exchanges (DEX):
Enhances liquidity and enables seamless cross-chain trading, contributing to the efficiency of decentralized exchanges.
Asset Management:
Facilitates the creation of diversified portfolios across multiple blockchain networks, fostering decentralized asset management solutions.
Cross-Chain Loans and Borrowing:
Empowers users to borrow and lend assets seamlessly across various blockchain networks, adding a new dimension to decentralized finance (DeFi). Users can leverage their assets across different blockchain networks, opening up new opportunities for lending protocols and decentralized borrowing. This functionality enhances the flexibility and accessibility of DeFi services, contributing to the evolution of cross-chain financial ecosystems.
Interoperable Smart Contracts:
Enables the creation of interoperable smart contracts, paving the way for complex DApps with cross-chain functionalities.
Token Swaps and Transfers:
Simplifies token swaps and transfers between different blockchains, expanding possibilities for utilizing tokens in various decentralized applications.
Cross-Chain Governance:
Extends decentralized governance models beyond individual blockchains, fostering collaborative and inclusive governance decisions for the entire cross-chain ecosystem.
These use cases demonstrate the versatility and transformative potential of LnM Custom Tokens in reshaping the decentralized landscape.
Invariants
When working with LnM (Lock and Mint) type of tokens, there are several invariants or key considerations to take into account. These invariants are essential to ensure the proper functioning, security, and usability of the token. Here are some important invariants for LnM tokens:
Locked Token Integrity:
The integrity of tokens locked on the source chain must be maintained. Any manipulation or compromise of the locked tokens could lead to security vulnerabilities and loss of value.
Minting Accuracy:
The minting process on the destination chain must accurately reflect the amount and ownership of the locked tokens on the source chain. Any discrepancies could result in a loss of trust and value for users.
Security of Locking Mechanism:
The mechanism used to lock tokens on the source chain must be secure and resistant to attacks. Proper encryption, hashing, and consensus mechanisms should be employed to safeguard the locked tokens.
Decentralization of Locking and Minting:
The process of locking tokens on the source chain and minting corresponding tokens on the destination chain should be decentralized. This ensures that the system is not reliant on a single point of failure and enhances overall security.
Interoperability with Source and Destination Chains:
LnM tokens should seamlessly operate and interact with both the source and destination chains. Compatibility and interoperability are crucial for the smooth transfer and utilization of tokens across different blockchain networks.
These invariants help establish a robust foundation for the implementation and utilization of LnM tokens, ensuring that they fulfill their intended purposes securely and effectively across different blockchain networks.
