Mantle Arb Fast Lane Release Notes

Thrilled to announce that the Arb Fast Lane bot now supports the Mantle blockchain!

With this initial release, the Arb Fast Lane is able to route trades through top DEXes, including:

• Graphene
• Velocimeter
• Agni
• Butter
• Cleopatra V2 & V3
• FusionX V2 & V3
• Merchant Moe
• Stratum

Self Funding

Self-funding empowers operators of the Arb Fast Lane to access trade liquidity directly from their wallet, facilitating cost-effective arbitrage transactions and enhancing competitiveness. This becomes particularly beneficial in chains where flashloan liquidity resources are scarce, such as Mantle.

Carbon DeFi Trade Splitter

This enhancement enables the bot to consolidate liquidity from "same token" pairs (e.g., ETH/token and wETH/token) for Carbon DeFi strategies into a unified liquidity source. This consolidation offers the advantage of expanding the bot's potential opportunities by increasing the accessibility of liquidity.

Multi-Deployment Support

Why limit yourself to just one Carbon DeFi deployment on a particular chain when you can have multiple? The arbitrage bot now boasts the capability to accommodate any number of Carbon DeFi deployments on a single blockchain! This substantial enhancement empowers the bot to simultaneously explore arbitrage opportunities across all Carbon DeFi strategies for every deployment on a blockchain.

Trade Splitter Support: Multiple Carbon DeFi Deployments

By combining trade splitter support with multi-deployment support, the Arb Fast Lane now boasts access to an even broader pool of liquidity. With the ability to aggregate same-token pairs from multiple Carbon DeFi deployments, the available liquidity for arbitrage continues to expand, bidding farewell to fragmented liquidity sources!

Upgraded Wrap/Unwrap Algorithm

The Arb Fast Lane bot already had the ability to add wrap & unwrap trades within arbitrage routes, however, the algorithm that powered this received a substantial upgrade. The new Carbon DeFi Trade Splitter algorithm required something that could handle much greater complexity, and thus the wrap/unwrap algorithm was upgraded to be significantly more robust. This new version is able to handle arbitrage routes that have much more complexity, while making further-optimized decisions.

Code Quality Improvements

Many features & fixes in this update included code refactoring to improve the general code quality.

Updated Handling of Gas Fees for Layer 2s

Dencun, the recent Ethereum upgrade, brought changes to gas fees for some Layer 2 blockchains, specifically Base & Mantle. The Arb Fast Lane was upgraded with handling for the new gas calculation functions and is now able to accurately calculate gas cost post-upgrade.

Fixes

• Enhanced the reliability of approval transactions for self-funding mode, ensuring smooth operation.
• Corrected fee discrepancies in some Solidly-fork pools within static data.
