Avalanche Granite is on the horizon, introducing key performance optimizations to continue to elevate the experience for builders, validators and the community.

From cheaper ICM verification, to biometric-secured dApps, to faster block times, let’s break down ACP-181, ACP-204, and ACP-226, the framework of the upcoming Granite upgrade👇 🔒 ACP-181: Enhancing ICM Verification

Before: P-Chain pointers updated every block → validator set was always changing → ICM messages risked invalidation.

Now: P-Chain height fixed for an epoch (5–10 min)
✅ Stable validator set
✅ Lower costs
✅ Reliable cross-chain messaging

Perfect for devs building cross-chain apps.

Validators have voted to raise the gas target to 2.2M gas/sec, further increasing network capacity.

This is part of Avalanche's dedicated effort to keep pushing throughput and network performance. The gas target defines how much computational work the C-Chain can process per second.

Higher target = more transactions & smart contract ops per second

Lower fees for users
Higher demands on validator hardware

How Avalanche Adapts Rate Limiting to Network Size

As the number of validators increases, the team has been working on ways to optimize the dynamic rate limiting system to automatically adjust based on network size. 🧵/ This approach uses statistical modeling to set appropriate thresholds, estimating expected request volume using normal distribution and set throttling at 4 standard deviations above expected levels.

After months heads-down shipping Etna & Fortuna, we're back with a new video series covering key platform updates and discussions for Avalanche builders 🫡

In this week's In the Lab: Avalanche Tech Updates, the @AvaLabs platform devs cover ACP-176 & the recent Octane upgrade 🧵 ACP-176 replaced the older mechanism with a market-driven model:

✅ Cheaper & more stable gas fees
✅ Validators can vote to adjust gas targets
✅ Min base fee removed, supply meets demand

Result: fewer spikes, smoother UX, higher throughput potential.

We’ve proudly completed a code audit with @OpenZeppelin for our Teleporter contracts, ensuring safety & reliability.

This underscores our commitment to security, setting the stage for safe, effective cross-chain functionality for EVM chains on Avalanche.
blog.openzeppelin.com/ava-teleporter… This audit was performed prior to production usage of Teleporter. Any identified issues did not affect a production instance of Teleporter.

The scope of this audit focused on the base contracts that are needed to interact with AWM through the EVM.

See image below for the audited contracts.

Teleporter is here, and now developers can easily build and users can freely use cross-Subnet apps offering full, fluid EVM interoperability.

Teleporter empowers developers to easily call contracts on other EVM chains within the Avalanche network, including the Avalanche C-chain, and makes developing Avalanche dApps extremely straightforward. With Teleporter, Avalanche blockchains can share any type of information with one another. Tokens, NFTs, oracle price feed data – any message can be communicated in a smooth, coordinated manner.

The Avalanche Frontier Consumer App hackathon is in full swing, and there's been some amazing workshops so far diving into various aspects of building on Avalanche 🫡

Here's the first 3 workshops so far 👇

Onboarding Through Smart Accounts and Social Logins with @ParticleNtwrk youtube.com/live/5zJQjsuX6…

Introducing AvalancheOps, the easiest way to spin up Developer Networks (Devnets) on #Avalanche with a custom VM. One command can spin up multiple validators across multiple regions in @awscloud and provide public endpoints to query nodes.


🧵👇:docs.avax.network/tooling/avalan… AvalancheOps is intended for quickly creating, testing, and iterating over various Avalanche network infrastructure configurations for testing and simulation.

Excited to announce the launch of @Circle’s Programmable Wallets beta on @avax. This is a new wallet-as-a-service platform that provides developers with infrastructure to embed Web3 wallets into their applications.

Let's take a look at some of the key features 👇

https://twitter.com/circle/status/1688903529304616961

Ease of Use 👌

The platform uses familiar REST APIs, and iOS and Android SDKs, enabling developers to manage and deploy users' wallets and transactions with less code. This makes it easier to develop and integrate wallets into existing apps.

The #HyperSDK has recently been enhanced with a significant upgrade

The core change involves transitioning from second-denominated block times to millisecond-denominated block times.

Detailed information can be found in the full PR: github.com/ava-labs/hyper… Historically, the HyperSDK employed a target-based system for block production, setting a goal for the number of blocks to be produced per second.

If this target was exceeded, a "surplus fee" was levied on each additional block. This fee could be offset by burning excess… twitter.com/i/web/status/1…

#Avalanche Cortina 3 is now out!

This version (v1.10.3) is backwards compatible with v1.10.0. It's optional but recommended.

Check it out here: github.com/ava-labs/avala… The release focuses on several key updates:

- Introduction of Push Query on Build
- Build Elimination of VersionDB from MerkleDB
- Fix for platformvm.GetValidatorSet BLS Key Retrieval issue

@chainlink functions allow anyone to connect a smart contract to any Web2 API, unlocking a new frontier of Web3 and Web2 integrations

And they are live on the @avax Fuji testnet - let’s dive into what you can build 👇 Previously, Web3 developers couldn't connect their smart contracts to existing Web2 APIs, and Web2 developers couldn't leverage their existing infrastructure when building a Web3 app

Chainlink Functions aim to solve this issue.

In our journey around the world of @avax, we are constantly being introduced to new revolutionary technological primitives that it’s hard to keep track

Let’s delve deeper into the novel blockchain communication system introduced back in Banff 5 - Avalanche Warp Messaging (AWM) Imagine a world where the Avalanche network is the entire globe, and the subnets are individual countries, each with their own unique culture, rules, and language

Within these countries, there are cities, which represent different blockchains operating each with their own openly… twitter.com/i/web/status/1…

Avalanche consensus is the most fast, scalable, secure, and energy efficient Consensus mechanism out today

Let’s play a game to visualize how it works 👇🏽 Imagine we're playing a game, and in each round of this game, each player (which we'll call a 'validator') has to ask a few other players (let's say, K players) about their preferred choice

The players they ask are chosen randomly from all the players, but those with more… twitter.com/i/web/status/1…

AvalancheGo v1.10.2 (Cortina 2) is here:
github.com/ava-labs/avala….

This version maintains backward compatibility with v1.10.0 but while optional - upgrading is highly recommended. This release includes major improvements to P-Chain API Latency. It has seen significant reductions, with platform.getStake latency reduced by a whopping 90%!

This is due to substantial enhancements in P-Chain caching, boosting the efficiency and response times of P-Chain APIs.

Cortina is live on Mainnet!

Cortina brings 3 key optimizations for the #Avalanche network:

➢ X-Chain Linearization
➢ Batched Delegator Rewards
➢ Increased C-Chain Gas Limit

What does this mean for @avax developers? 👇 1️⃣ X-Chain Linearization

The X-Chain migrating to Snowman++ moves the entire network to a single consensus engine, enabling faster development and more broadly-applicable innovation.
