A very accurate and thorough rundown of Atlas, the Execution Abstraction protocol, written by our friends at @l2iterative 👀 these guys know what’s up.

Did a deep dive on Atlas. If you’re big into Account Abstraction, you will love what @0xFastLane is doing with Atlas and Execution Abstraction.

1/ Next up from our Makers and Breakers in the Rockies tech talk series is "Strategies for Building Robust Smart Contracts" from @alphaK3Y, a first-principles deep-dive into building secure smart contracts
The biggest L2s of this cycle will be modular and composable enabling them to supercharge their ecosystem growth while keeping transaction costs low.
Discourse in the crypto community suggests that we don't need any new application types, and that we should focus exclusively on improving existing applications. Indeed, this discourse is wrong, let's talk about Multichat. 🧵
Introducing Atlas Backruns, the first permissionless backrun OFA that doesn’t require PBS, and is compatible with all L2s. Powered by Atlas “Ex-Post Bids”, an on-chain “block building time” simulation engine.
As we wrap up audit, we are excited to share Atlas Backruns, the first of many Atlas Modules, aimed at letting applications auction off backrunning rights and share proceeds with users and protocol stakeholders like LPs Read more from @0xdoge_bull here: x.com/0xdoge_bull/st…

@potuz_eth @TimBeiko so I absolutely support @ThogardPvP who figured it out and is raising hell about it the criticism shouldn’t be: why dapp devs rais the alarm so late? it should be: why EIP writers (consensys workers then) weren’t transparent about this GIANT issue???
I have a new article out, on CEX/DEX arbitrage mechanics and the implications for Uniswap LPs! Link in comments --->
The first generalized intent smart contract is now >50% done with audit... @atlasevm is imminent.
Everyone: “Why are you picking a fight with the most powerful company in DeFi? Do you want to hurt yourself?” Me: “well actually..” youtu.be/mSjLpdPnME4?si…
it literally kills me when projects announce infra partnerships like it’s a big deal that blockchain and that bridge will be abstracted away, it’s all a commodity the only thing that can’t be abstracted away is the simple delight your actual product simply delivers to users
Every L2 is an L1, some just haven't realized it yet.
quick reminder: the point of modular wasn’t to own the full stack.
At FastLane, we're big believers in credible neutrality. That's why after successfully antagonizing the 3074 crowd, we think it's only fair to have the 4337 crowd pissed off at us, too 😁 tldr: intents + 4337 mempool = reduced execution quality fastlane.xyz/blog/on-4337-i…
ERC-4337 is a powerful permissionless AA solution for general purpose user ops, but may not be the best place for more complex DeFi intents (the flip side of MEV) We explore the tradeoffs and relationship between ERC-4337, intents and MEV here fastlane.xyz/blog/on-4337-i…
3074 = permissioned by wallets. Good luck building an app that uses 3074 that isn't approved by metamask. It's such a funny coincidence that the team that is the loudest advocate of wallet-permissioned building just so happens to be the biggest wallet. What are the odds?

Diversify your bonds.So we @aori_io realized the only way to actually onboard programmatic traders was to build a translation layer for them that parsed defi in a way they understood... not as INTENTIOOOONS but instead as: LIMIT ORDERS. 5/n
I think I need to write important thread on perhaps one of the most under explored questions in DeFi… if market makers are so sophisticated why do ONLY 2 dominate all on-chain trading?
At L2IV, we believe Atlas is poised to redefine transaction execution standards in DeFi. Thanks to @ThogardPvP and the entire FastLane team for their insights on the article and cooperation during our assessment of Atlas and FastLane. Whitepaper: fastlane.xyz/Atlas_Whitepap…
From this comparison we believe that Execution Abstraction through Atlas can be applied across various sectors within the blockchain ecosystem, each tailored to address specific needs and challenges, including:
Atlas offers a more integrated, cost-effective & balanced approach to customizing execution.
- Composability: integrates with the ecosystem; appchains may face isolation - Infrastructure: uses the main chain; appchains require separate infrastructure - Trade-offs: balances key factors; appchains may compromise
Apart from the above, we also believe its important to compare Atlas with Appchains. While both Atlas (Execution Abstraction) and appchains offer increased control over the execution environment, they differ in key aspects:
- Pre-operation hooks: Set conditions & checks - User operation hooks: Define core transaction logic - Solver operation hooks: Specify solver requirements & assistance - Post-operation hooks: Handle cleanup & additional actions Well-designed hooks unlock Atlas's full potential
And arguably most critical component of the Atlas module are the hook functions that allow developers to customize the interaction between the Originator and Solvers, as well as define the pre-conditions and post-conditions for execution to be considered successful.
For Auctioneer and Bundler, Atlas module must specify who can assume these roles for the particular use case. The options include
For Solver Bid valuation, the Atlas module must define how these Solver bids are evaluated and compared. This can be based on various criteria, such as:
To integrate Atlas, an app or wallet must publish an Atlas module (a smart contract) that defines: - How solver bids are valued - Who can be the Auctioneer and Bundler - The hook functions that determine how the Originator and Solvers interact
atlETH It plays a crucial role: - Enabling solvers to escrow funds for gas consumption, ensuring that operations are financially backed & preventing spam or insincere actions - Supporting an Atlas-native cross-operation flash loan system, allowing for complex transaction flows
Atlas also introduces atlETH, wrapped ETH within the protocol. atlETH enables solvers to escrow funds for gas consumption and supports an Atlas-native cross-operation flash loan system, ensuring financial backing and security against spam and insincere actions.
Based on our internal research and understanding with the FastLane team, this is how a transaction is processed with Atlas:
Architecture: Originator: Initiates the process with a signed operation Solvers: Propose solutions to internalize MEVful / fill intents Auctioneer: Aggregates & sorts operations Operations Relay: Middlemen b/w parties Bundler: Generates and submits the full Atlas txn onchain
Key features of Atlas: - Captures & redirects value from operations to users, DAOs, or public goods - Uses EIP 712 messages (operations) as building blocks for decentralized, trustless transactions - Enables atomic, reorg-resistant operations within a single transaction
Atlas also allows for the internalization of value generated by operations, ensuring a more equitable distribution of value. By bundling operations into a single transaction using smart contracts, Atlas maintains decentralization and trustlessness.
Unlike traditional MEV bundles, Atlas allows operations to reference each other in any direction within the same transaction. This provides atomicity & protection against chain reorgs, ensuring intended execution order & preventing value leakage.
Atlas achieves this through EIP 712 messages called "operations" that are bundled into a single transaction. This bundling process is crucial for maintaining decentralization & preventing manipulation of execution order.
