Release Notes
💥 Announcing the Latest Round of Arb Fast Lane Developments
✅ Pool Finder - Improved Support for New Token Pairs
Pool finder functionality now allows the bot to discover and support arbitrage on newly created pairs on Carbon DeFi and all licensed deployments, better supporting new meme tokens.
When the bot starts it will:
• Search for any Carbon DeFi pairs that have no counterpart pool present in static data
• Search for such pools using supported DEX factories
• Repeat this action every 100 iterations (configurable) of the bot's main loop
✅ Better handling Multicall errors
Moved to multicall 3 with advanced error support implemented in order to:
• Enhance error reduction and improve error handling within a multicall
• Enable the bot to effectively manage and overcome errors, ensuring continuous and efficient operation.
✅ Private transactions on Ethereum
Addressing frontrunning is crucial on Ethereum.
The community identified issues with private transactions sent to the default Flashbots operator, resulting in failures. In response, the bot now supports the option to send transactions privately to a second operator, MEVBlocker.
• Moved from flashbots to MevBlocker
• Enabled access-lists
✅ Moved from newFilter to eth_getLogs for better support
As Carbon DeFi and licensed deployments expand to an increased number of blockchains, improving the process for fetching blockchain data became a priority. Transitioning from newFilter to getLogs offers robust enhancements in data retrieval and provides better support for all EVM chains.
• Moved to eth_getLogs to have support across more chains
✅ Fixes around Bancor POL support
Handle tokens which are no longer tradable due to low price (any token for which the POL contract function tokenPrice reverts)
✅ Bugfix - the notorious
last_updated_blockkey errorThis error was reproduced and fixed. Thank you to the bot users who reported this issue.
✅ General Code Improvements
A major cleanup and careful improvements in performance and efficiency are currently underway. For example - by better validation trade instructions and transactions before sending them.
