How it works

Base has a "block" that is created approximately every 2 seconds. We send this straight on to the Coinbase Sequencer to ensure inclusion times are not impacted.

When a transaction is sent via Blink, we will share with our trusted searcher network. The searchers will be allowed to send backrun transactions to take advantage of arbitrage opportunities.

To be part of this trusted network, the searcher will pass back some of that value to the transaction originator.

Flow Overview

1. Transaction Submission

   • Users submit transactions through Blink interface

   • Transactions are immediately processed for searcher distribution

2. Searcher Integration

   • Vetted searchers receive transaction details

   • Searchers analyze for profitable backrun opportunities

   • Execution happens within the same block when possible

3. Profit Distribution

   • Searchers capture arbitrage value through backrun transactions

   • Automated profit-sharing mechanism returns value to original transaction senders

   • Transparent tracking ensures fair distribution

Differences with Ethereum

1. Cheaper gas = higher quantity of profitable Opportunities

Because it's cheaper to send transactions on Base, the point at which opportunities become profitable for searchers is lower. This means that much lower value transactions can provide value back.

2. No Builders

There are no builders on Base. The Coinbase run sequencer decides the ordering. As of December 2024, ordering is done by the Gas Price.

3. No Mempool

As Coinbase runs the sequencer, a public mempool is not necessary. This means there is no way for user's to be explicitly "sandwiched" by MEV bots like the notorious jaredfromsubway.

However, sandwich attacks still occur on Base. Please reach out to us if you're interested in more details.

4. No "Bundles"

There is no concept of "bundles" on Base. This means it's harder to attribute value recovered from the searcher.

Blink have a number of innovative approaches to ensuring that we can track the value we pass to searchers and pass as much as possible back to the originator of the transaction.
