Introducing Full Send, the fastest way to get your transactions included on Ethereum mainnet.

Built on DA Builder, Spire’s aggregation layer.

It’s live today. Try it now ⚡️ Full Send sits between wallets and chains, optimizing how your transaction gets included on Ethereum.

You can start using it right here: spire.dev/fullsend

1/ Shared Blob Compression & Aggregation 🫂

A design to optimize blob space for appchains/rollups. 🧵👇 2/ The Problem:

As appchains (rollups) grow, they often:

• Submit underutilized blobs to DA layers (wasting space & money).
• Face L1 block limitations (not enough blob slots).

This leads to inefficiency and high costs.
Enter blob sharing. 🧩

How do based rollups actually work?

🧵 Let's break down what happens when you send a transaction: 1. A user sends a transaction to an RPC.

They won't even know they're using a based rollup! But they will see an almost instant confirmation that their transaction has been accepted because of... preconfirmations ✅

Everyone is talking about based rollups - but how do based blocks get built?

🧵 It's time to break down the steps involved: Ethereum is transactions. L1, L2, L3... it's all transactions and the ordering of those transactions is important because money can be made by controlling the execution order - known as MEV.

Sovereignty and Composability: breaking the appchain tradeoff once and for all

Spire Labs has raised $7m to orchestrate the development of the Based Stack - the next generation of based rollups. We are excited to announce our seed funding rounds, led by @Maven11Capital and @anagramxyz with participation from @a16zcrypto CSX, @BanklessVC, @VoltCapital, @l2iterative, @FinalityCap, and @DCGco.
