Introducing the x402 Bazaar: The open, machine-readable discovery layer for x402.

Imagine a dynamic, vibrant ecosystem where specialized AI services, data feeds, and APIs can thrive. A search engine for agents.

This is how the machine economy gets bootstrapped. 🧵 API providers: The x402 Bazaar means distribution.

List your x402 endpoint – its schema, price, a clear description – and suddenly, AI agents and developers building on x402 can find your service. This is how you tap into the coming agentic economy. Permissionless and open.

We are excited to introduce x402–a new open source payments protocol built on HTTP rails.

Let’s break it down: x402 is fixing the internet’s first mistake.

Onchain payments are now easy and frictionless, opening new use cases for agentic commerce for API providers, context retrieval protocols, content creators, and more.

You’ve probably heard of @eigenlayer by now.

The restaking protocol continues making waves as the ETH deposits pour in. Over the past week, its TVL has jumped to nearly $8B.

Let's dive in — even if you’re a protocol pro, you might learn something new. 🧵 What’s EigenLayer?

It’s a protocol designed to extend Ethereum's economic security (courtesy of ≈30M staked ETH, or nearly $88B) to secure a broader range of decentralized services.

It accomplishes this by introducing the novel concept of "restaking."

Happy @arbitrum Day! This time last year, the @offchainlabs Nitro upgrade went through and on August 31, 2021, Arbitrum One launched!

There’s no shortage of innovation coming from @offchainlabs team and today is no different. What has the team been building? 🧵 2/ Let’s start with Orbit 🪐

The ability to launch your own custom chain with ease has become invaluable. Within the Arbitrum ecosystem, Orbit allows you to do just that, offering options such as rollups like Arbitrum One or AnyTrust chains like Arbitrum Nova.

1/ 🎉 Coinbase Wallet as a Service has now launched on mainnet, bringing seamless web3 onboarding to everyone, everywhere! 2/ With Wallet as a Service, users can create, access, and restore their wallets using just a username and password, all embedded directly within your app.

1/ Coinbase Cloud has been supporting @Solana since their earliest testnets. As a leading validator, we wanted to highlight Solana’s latest technical progress for the community. 🧵 2/ There are two improvements that stand out:
- The network has been upgraded to fix the issues that led to prior outages
- As a testament to the efficacy of these upgrades, the network continues to run under meaningful load and it has done so successfully over the past two weeks

Flashbots’ MEV-Boost is now live on Coinbase Cloud. Our ETH staking customers can now opt-in to receive MEV (maximal extractable value) rewards enabled by proposer-builder separation (PBS). Coinbase Prime and Retail customers staking ETH will earn additional rewards automatically 2/ MEV-Boost is a free and open-source middleware. It implements PBS, which minimizes the negative externalities of MEV by creating a competitive marketplace for builders to form profitable blocks and trustlessly communicate with proposers (validators) through relays.

1/ 🚨 Hey $DOT holders, the active vote to enable Nomination Pools 🌊 on @Polkadot helps small stakers in a BIG way! A 🧵 on the referendum and how it’s a win/win for users and network decentralization! 2/ Referendum 78, enabling Nomination Pools on Polkadot, is open for voting! So what would this change if it passed? polkadot.polkassembly.io/referendum/78

There are many routes a developer can take when creating a dapp within Cosmos:
🔨a smart contract application on a chain
⚒️ a independent appchain, and soon
🛠️ an interchain secured appchain.

By providing different options, devs can build their app towards its full potential 🧵 2/ Lets do a quick dive into the new feature coming to the @cosmossdk - Interchain Security!🌌

First off, Interchain Security (ICS) is a shared security solution for the Cosmos ecosystem being pioneered by the @cosmoshub.

1/ @solana, spam, and a chance to fix it 🧵:
- QUIC
- Stake-weighted QoS
- Local fee markets

Let’s dive in ⬇️
coinbase.com/cloud/discover… 2/ Solana has seen explosive growth over the past year. A consequence of that growth (and the original design), however, has been spam.

To combat spam, these huge changes have been under development.

Here are the highlights:

1/ Congratulations to the @0xPolygon team for the announcement of their Polygon #zkEVM! This a huge feat for scaling Ethereum and zk technology.

What’s difficult about zk proofs and scalability, and how does the Polygon zkEVM try to solve them? Read on… 🧵 2/ Zk proofs are time-intensive and expensive to generate. On top of that, EVM support and compatibility is a problem. In order to build on top of a zk rollup, you may need to learn a new coding language and dev environment.

1/ Aaaaand we’re back with the Eth2 updates! Let’s dive back in:
🧵 2/ The Gray Glacier upgrade that delays the difficulty bomb to mid-September 2022 was successful.

1/ We told you that we’re working on client diversity on eth2. Today, we’re excited to share an update. 👇🧵

2/ We completed our work on remote signers for Lighthouse, offering double signing protection via high watermark software. This let us reach an important milestone: currently, Coinbase Cloud validators are distributed roughly evenly across Lighthouse and Prysm.

1/ gm frens! Who else is excited about Superfluid Staking on @osmosiszone ?

In this thread we’ll summarize what we know about the upcoming launch and how you can participate.👇 2/ What is Superfluid Staking? (SFS)

Superfluid staking is the ability to use liquidity provider (LP) tokens to participate in staking on @osmosiszone. This is similar to the idea of liquid staking, but in reverse.
