#GM!

1/ How do the cross-chain #bridges works? In this #visualguide, we explain how assets are transferred between chains and how interoperability becomes a fundamental aspect of the future.

#DeFi #Cryptocurrency #Ethereum #Bitcoin $ETH $BTC Image
2/ Blockchain networks are very fluid and efficient as single entities but lack the ability to communicate with each other. This creates demand for seamless transfer across different chains without using centralized exchanges as intermediaries or selling the token first. Image
3/ Cross-chain #bridges solve the problem by enabling the transfer of tokens, smart contracts, data, feedback, and instructions between two independent chains without intermediaries. Image
4/ In general, cross-chain #bridges are divided into two based on the transactions validator: trustless bridge and trusted bridge. Image
5/ Based on the purposes, #bridges can be classified into:
- Asset-specific @WrappedBTC
- Chain-specific @auroraisnear, @NEARProtocol ~ Rainbow Bridge
- Application-specific @THORChain, @compoundfinance
- Generalized @axelarcore, @LayerZero_Labs Image
6/ Based on the architectures, #bridges also can be classified into:
- External validators & federation
- Light clients & relay
- Liquidity providers' network Image
7/ By understanding the #bridges architecture we can look at different traits that explain the strength and weaknesses of each bridge. Image
8/ Wrapped tokens are an integral part of the #bridges to achieve interoperability. Assets that are transferred to the bridge will be minted in the form of wrapped token that adheres to the rules, data, and contracts (native) on the destination blockchain. Image
9/ In this diagram we can see how assets move between chains by using the lock & mint mechanism and burn mechanism. These two mechanisms are the most popular and versatile to move assets across multiple chains. Image
10/ Existing blockchain #bridges face the interoperability trilemma, current designs cannot satisfy all three traits. There is always some level of compromise. Image
11/ Despite facing the trilemma, cross-chain #bridges are still important because they can increase asset productivity, improve user experience, and support the distribution of liquidity across the chain and decentralized apps (dApps). Image
12/ #Bridges are not without issues, growing concerns directed toward asset centralization and imbalance of liquidity. Security also becomes a big problem since the massive assets deposited lure hackers to steal and exploit the bridges. Image
13/ #Bridges attacks not only target the asset custodians, but other targets such as asset issuers, smart contract vulnerability, and bridge users are also prone to security hacks. Image
14/ Beyond the #bridges: #eWASM is a project to bring highly flexible, near-native performance and optimization of web assembly for Ethereum to achieve interoperability and flourish application developments on #Ethereum.
@ethereum Image
15/ Beyond the #bridges: Layer-0 like @Polkadot and @cosmos allows developers to create custom blockchains that can be tailored to their requirements by combining various elements from different L1s while retaining their own ecosystem

16/ Beyond the #bridges:@axelarcore, @LayerZero_Labs, @OneAnalog, and @MapProtocol are several examples of projects that focused to bring interoperability across the chains. Image

➥ x402 Revival: The Internet’s Native Payment System

The internet always had a payment code called HTTP 402, but it was never activated.

x402 finally activates it, turning the web into a programmable payment layer for both humans and AI agents.

Everything you need to know about x402 in 30s 🧵

— — —

► What is x402?

x402 is an open payment protocol by @coinbase that enables instant stablecoin payments over HTTP (Hypertext Transfer Protocol).

It activates the unused HTTP 402 Payment Required code, originally meant for online payments.

The name means “extended 402”, a modern version of the HTTP 402 code built for digital payments.

With x402, websites, APIs, and AI agents can send or accept payments instantly without accounts or intermediaries.

Core features:
▸ Instant settlement: Payments confirm within seconds
▸ Zero protocol fees: No base-level charges
▸ Blockchain-agnostic: Works across @base, @solana, @0xPolygon, and more
▸ One-line setup: Accept crypto payments with a single line of code



► How it Works

x402 works through standard HTTP requests and responses.

❶ Request: A user or AI agent requests a paid resource.
❷ Response: The server returns an HTTP 402 code with payment details in JSON.
❸ Payment: The user sends $USDC through an x402 facilitator like Coinbase.
❹ Verification: The server verifies payment using /verify and /settle endpoints.
❺ Access: Once confirmed, access is granted instantly.



► Why It Matters

The internet never had a native way to process payments.
Developers depended on cards, ads, or subscriptions that were slow and expensive.

x402 changes this with instant, usage-based payments between users, APIs, and AI agents. It removes intermediaries and lets value move as easily as data.

It enables real micropayments, where users pay per API call or file instead of monthly subscriptions. As AI agents start transacting independently, x402 becomes the foundation for fast, programmable online commerce.



► AI Agents and Adoption

AI agents use x402 to pay for compute, storage, and data in real time.
They also trade services in agent-to-agent marketplaces and power in-game transactions, where NPCs can buy and sell assets automatically.

Developers use x402 SDKs in @TypeScript or @PythonPr and sign payments through CDP Wallet API or viem/ethers.

Adoption in the last 30 days:
▸ 43,000+ transactions
▸ $50,000+ total volume
▸ 300+ buyers
▸ 190+ sellers



► Ecosystem

▸ @AEON_Community
▸ @AurraCloud
▸ @onbonsai

▸ @CoinbaseDev
▸ @daydreamsagents
▸ @fluora_ai
▸ @LatinumAI
▸ @mcpaytech
▸ @mrdn_finance
▸ @PayAINetwork
▸ @x402rs



► Wrap-Up

x402 revives the forgotten HTTP 402 code, creating a native payment layer for the internet.

It enables instant, account-free USDC payments between websites, APIs, and AI agents.

By combining open web standards with on-chain settlement, x402 removes payment friction and bridges the web with decentralized finance.

As AI and automation grow, x402 could become the foundation for permissionless, instant payments across the internet.

➥ The Bidding War for $USDH

The competition to deploy @HyperliquidX's upcoming native stablecoin is becoming increasingly intriguing.

Currently, three 3 have been submitted by established stablecoin issuers:

❶ @Paxos ⟶ Regulated, institutional bridging ready
❷ @fraxfinance ⟶ DeFi-native efficiency
❸ @withAUSD ⟶ Collaborative, scalable infrastructure

Let's also remember that @circle is planning to launch native $USDC on Hyperliquid (it's a bit too late imo).

Below, I will outline the main proposals and then compare them in a table for clarity. ↴Image
➠ Which one do you think have the best proposal for USDH?

Disappointed with airdrops and points? Raise your hand!

Many of us feel duped by the paltry amounts we get after completing tons of tedious tasks.

But what if you could flip the script and profit?

You're in for a treat👇🏻 Image
►Points and Airdrop Meta is Here to Stay, But...

Points and airdrops have become the new norm.

They reward early adopters and drive platform growth by incentivizing key activities.

However, these points often leave stakeholders frustrated, impacting everyone from users to project developers.

Is there any better way to solve this?

Yes, it is. It's called points tokenization.Image
► Points Tokenization

Several solutions, such as points secondary markets, already exist, but they come with limitations:

- Platforms require extra collateral and cap buyer payouts.
- Fixed-rate protocols block point resales, creating liquidity headaches for sellers.
- Some markets restrict individual point trading, stifling user flexibility.

And @RumpelLabs' points tokenization sweeps these issues away for good.Image
