Ten Thousand Times Titan

We officially launched Titan just over two months ago, and having recently built our 10,000th block on Ethereum mainnet, we thought it would be a good time to write a brief first post to introduce ourselves.

About Titan Builder

We are a crypto-native team with deep experience across the transaction value chain, having previously been miners, validators, searchers and traders across multiple Layer-1s, before embarking on this block building journey.

Our mission is to build a fair, transparent and independent builder that can be trusted by all Searchers and Traders on Ethereum. We are also working hard to develop a suite of infrastructure products and services to improve the UX for Searchers and Traders, and further their possibilities.

Our Approach to Block Building

Our goal is to always build the most valuable block possible, and as such we do not apply filtering of any kind, and do not censor any transactions or bundles. Our builder runs multiple sorting algorithms concurrently (from simple gas price sorting and basic greedy algorithms, all the way to much more advanced proprietary models), that compete against each other to maximise block value. We also concurrently operate multiple instances of our builder in different geographic locations.

As a result, sorting of bundles and transactions is not necessarily ranked by effective gas price, and consequently top-of-block execution is not guaranteed. Based on how transactions interact with each other and the current state, including transactions with lower effective gas prices before higher paying ones may yield more valuable blocks, which as mentioned previously is what we always optimise for. We will never unbundle a bundle (except where opted-in by the sender for advanced bundle-merging), and will never broadcast any bundles or private transactions to the public mempool. We also submit to both OFAC and non-OFAC compliant relays, building and broadcasting separate block-versions in parallel whenever non-OFAC compliant transactions are present.

What’s Next?

In an effort to provide more transparency around the Builder landscape, we will be releasing a series of research articles using our proprietary data to produce unique insights that we hope will help further illuminate the dark forest.
