Protocol for unifying cross-chain liquidity on polkadot

Direct blockchain utilization happens when sending cross-chain messages, while API usage occurs when asset exchange happens or during best-price outcome queries. Crosschain interoperability is the capability that allows separate blockchain networks to communicate, share data, and transfer assets seamlessly. This enables decentralized applications and digital assets to operate across multiple blockchains, fostering connectivity within the ecosystem. Crosschain interoperability allows independent blockchains to interact, exchange assets, and share data.

• This situation adversely impacts users within this industry, as they cannot issue additional shares or derive benefits from existing ones.
• One is where IBC works as expected, and the other is where the message fails to be delivered due to a timeout or an unreachable destination.
• The architecture overview in Figure 1 (Polkadot architecture overview) shows that Polkadot contains a Relay Chain, which is the leading chain responsible for network security and validating blocks.
• Depositing and unwrapping AVAX token using GMP (Send a wrapped native token).
• However, the protocol can also be extended to support other blockchain platforms.

USDT represents an excellent example of how liquidity can be fragmented across the Polkadot network. Co-developed by Across Protocol and Uniswap Labs, ERC-7683 introduces a universal, standardized framework for crosschain Intents across the EVM ecosystem. It supports seamless interoperability between Ethereum mainnet, L2 chains, rollups, appchains, and sidechains in an accessible, scalable, and secure manner. ERC-7683 addresses the need for consistent, crosschain functionality, making it simpler for developers to build and for users to interact across these networks. Intents-based interoperability is rewriting the rulebook for crosschain actions.

FAQ: Understanding Crosschain Interoperability

Consider a hypothetical scenario where the trading market for a specific parachain is grappling with liquidity issues due to a myriad of problems. Different blockchains have varying transaction throughput and block confirmation times. For example, Bitcoin’s block time is around 10 min, while Solana processes transactions much faster.

• If we find the desired amount, we will take the DOT from other chains to AssetHub.
• Therefore, we should teleport the assets from the origin chain to AssetHub; in this case, the origin chain for DOT is Polkadot.
• If you’re a crypto native, you probably know just how tedious and frustrating it can be to interact or move funds across chains.
• • Cross-Chain Gateway Protocol (CGP) – enables routing and discovery of addresses/applications across different blockchain networks.

As we try to unify liquidity, some decentralized exchanges can become congested, creating higher fees. This can be solved by using alternate routes or distributing the swap amount to multiple exchanges. In the case of a sharing economy, e.g., peer-to-peer car sharing (Valastin et al., 2019) that uses platform-specific tokens to pay for rental services, we do not need to find the token, swap it, and then use it.

Crosschain interoperability connects isolated blockchain ecosystems, enabling seamless asset transfers, data sharing, and collaboration across chains. By reducing fragmentation, enhancing liquidity, and simplifying user experiences, it unlocks a unified, collaborative multichain environment. Technologies like atomic swaps, bridges, and Intents drive this transformation. Across Protocol’s Intents-based solution provides secure, fast, and user-friendly crosschain interoperability. Standards like ERC-7683 make Intents-based interoperability scalable, secure, and accessible for developers and users alike.

The other issue is the verification of the token amount that is being transferred. Malicious chains can manipulate the transfer amount, saying they burned more tokens than the transferred amount, creating a supply mismatch between the bridge-connected chains. As the blockchain landscape evolves, crosschain interoperability has become the cornerstone that unites networks, driving a truly interconnected onchain world—and we’re excited to be part of it. Protocols like Interledger and Everclear use this technology to simplify crosschain payments and bridge gaps between financial systems. For example, ILPs make it possible for a payment to pin up casino start on one blockchain, hop through multiple connectors, and settle on a completely different blockchain—all without compromising security or speed. This process enhances liquidity, reduces complexity, and helps blockchains work together, making crosschain payments smoother and more reliable than ever.

Looking outside the ecosystem, Polygon (Kanani et al., 2021) is a good example of a network trying to unify liquidity across its ecosystem. Using the Polygon CDK, connected chains can share liquidity and assets, enabling developers to build applications that interact within the Polygon network (Polygon AggLayer). The Aggregation layer chains can submit transactions to the Ethereum network, allowing for the seamless transfer of assets between the two networks. Moreover, the Aggregation layer enables asynchronous cross-chain communication, calling contracts from one chain to another without finalizing Ethereum.

However, the problem of liquidity fragmentation will persist in the Polygon network, as the AggLayer will only work with chains built using the CDK. In the case of Cosmos, the problem of liquidity fragmentation is complex as tokens can come from various sources – EVM (injective), CosmWasm, or native IBC tokens. To unify liquidity, the naive way is to transfer all via IBC to Osmosis and swap all tokens to the desired one. However, there are more efficient ways to unify liquidity, as it will result in a significant loss of value due to high slippage and fees. Furthermore, many additional steps are needed to ensure that tokens are in one network. Despite all its exciting potential, achieving full crosschain interoperability comes with challenges.

The response time is relatively standard for European servers, considering the median ranges from 558 to 1,061 ms, respectively. In Figure 9, we can see that the number of requests mentioned only slightly fills the server memory. We can also see a marginal difference in the cross-chain capabilities of users using applications that implement our solution compared to the standard PolkadotJS UI. Crosschain interoperability also simplifies and enhances user experiences across different chains. Retail users benefit from crosschain interoperability through seamless asset transfers, reduced transaction fees, and access to larger liquidity pools for DeFi and trading.

In the optimistic case, where the fill is not challenged within a predetermined time frame, OriginReactor releases the Swapper funds and the Filler bond back to Filler, completing the swap. In that case, Filler must provide valid proof of execution to the Oracle. If the evidence is valid, Filler receives the funds, the bond, and the challenger’s bond. Conversely, if the proof is invalid, Swapper funds are returned, and the challenger receives a portion of the Filler’s bond as a reward for identifying the invalid fill.

The first scenario involved sending 1,000 requests to the Router API quickly. This test was performed ten times; therefore, we created 10,000 requests. The API’s process of generating calls can be observed in Figure 10 while the complexity of each request is shown in Equation 1. This test also analyzed how API performed in a high-load situation and whether memory was efficient enough to meet demands.

Security risks remain a concern, as bridging protocols can expose funds to vulnerabilities. Scaling the infrastructure to handle crosschain transactions is another hurdle, particularly as user demand increases. Additionally, the lack of standardized governance and protocols across blockchains can hinder interoperability, highlighting the need for universal standards to ensure smooth, compliant interactions.

• Comprehensive analysis of the architecture of the Polkadot ecosystem, security considerations, and native cross-chain protocols. So, how do we ensure that crosschain interoperability enables Web3 applications to better meet both onchain and real-world needs? Sidechains are like the side roads that you can take when there is too much traffic on the blockchain highway. They operate as secondary chains running parallel to main blockchains, designed to offload transactions and increase scalability. The test objective was to create successful cross-chain transfers from two Parachains with different XCM pallets implemented to compare the ability of abstraction in interfaces.
