# Ethereum Tipping Contract The Ethereum Tipping Contract lets users send ETH tips through bloXroute instead of paying the full tip directly as priority fee or direct coinbase transfer.\ \ The goal is simple: help users keep their transactions and bundles competitive for builder inclusion while improving the economics of their orderflow.\ \ Instead of sending the full bribe directly to the block builder, eligible users can send the tip to bloXroute’s tipping contract. The contract routes the required portion of the tip to the relevant builder and tracks any eligible retained value as a claimable kickback for the sender.\ \ Contract address: `0x5d606b4e3BAEA7030162DFa9bF7dAcC046eEbbbe` #### Why use the tipping contract? **Improve orderflow profitability**\ When you tip builders directly, the full tip is paid away. With bloXroute’s tipping contract, eligible exclusive senders may receive a portion of the tip value back as a **kickback**, while still keeping the builder incentive competitive enough for strong placement and landing rates.\ \ **Keep builder incentives competitive**\ The contract is configured to preserve a sufficient effective builder payment relative to competing orderflow. This helps avoid reducing inclusion probability while still allowing eligible users to recover value.\ \ **Works across orderflow types**\ The tipping contract can be used for both standard private transactions and bundles.\ \ **Kickbacks for exclusive senders**\ Kickbacks are available to whitelisted users who send orderflow exclusively through bloXroute.\ \ For eligible users, kickbacks are calculated based on tip value sent through the contract and accrue as claimable on-chain balances.\ \ Exclusivity and kickback eligibility are granted case by case.
