The testnet of chainvast is in progress. Our own L1 based on the Avalanche L1 will be live soon.

Developer Tools & SDKs

AvaCloud SDK

• Official TypeScript SDK (@avalabs/avacloud-sdk), offering:

  • Data API, Metrics API, and Webhooks API

  • Structured, paginated access to on‑chain data, chain health, throughput, staking rzlt.io+9developers.avacloud.io+9github.com+9.

  • Supports multi-chain queries (Avalanche, Chainvast, Ethereum).

Core Developer Utilities

Web3 & RPC Support

• Public & private RPC endpoints with full JSON-RPC compatibility (works with ethers.js, web3.js, MetaMask) for smooth dApp development.

Smart Contract Ecosystem

• Full EVM compatibility via Subnet-EVM, unlocking Solidity/Vyper use with tools like:

  • Hardhat, Foundry, Truffle, Remix developers.avacloud.io+1developers.avacloud.io+1build.avax.networkreddit.com.

• Support for precompiled contracts enabling enhanced features: token minting, fee management, governance.

Data & Monitoring APIs

Webhooks & Real-Time Events

• Webhooks API for live notifications of transactions, events, and network health alerts developers.avacloud.io+2developers.avacloud.io+2developers.avacloud.io+2.

Interoperability & Integration

Avalanche Warp Messaging (AWM)

• Full integration for cross-chain messaging and asset bridging with other Avalanche Subnets — available out-of-the-box build.avax.network+1coindesk.com+1.

Security, Auditing & Wallets

Integrated Account Abstraction

• Built-in social wallet flows, gas estimation, and signing support

• Ecosystem integrations: Core SDK, WalletConnect, 0xGasless, Biconomy, Particle, ZeroDev gam3s.gg+2rzlt.io+2olagg.io+2build.avax.network.

Security & Audits

• Compatibility with audit tools: OpenZeppelin, Certora, Trail of Bits, Least Authority, Nethermind; integrated vulnerability checks build.avax.network.

Enhanced Dev Experience

Performance & Testing Infrastructure

• Local dev environment via Avalanche‑CLI’s local network runner

• Parallel tx workflows, gas tuning, full-stack transaction debugging support.

12. Full SDK & API Ecosystem

• The AvaCloud SDK provides holistic integration with APIs and chain tools:

  • Example setup:

    Copy

    tsCopyEditimport { AvaCloudSDK } from "@avalabs/avacloud-sdk";
    const sdk = new AvaCloudSDK({apiKey, 1991, network});
    const metrics = await sdk.metrics.chainThroughput({ChainId});

INVAST uses a custom Snowman++ based L1 with the following features:

• Leaderless: No single validator is responsible for block proposals, reducing attack vectors.

• High throughput: Can handle thousands of transactions per second (TPS), with sub-second finality.

• Byzantine Fault Tolerant (BFT): Secure even if up to 1/3 of validators are malicious or offline.

• Finality in under 2 seconds (often under 1 second on performant subnets)

• Validators gossip about transaction acceptance probabilities, updating iteratively until consensus is reached.

This approach enables fast and secure transactions while keeping energy use low. It also prevents centralization and protects against malicious attacks by applying public blockchain security checks, ensuring a fair and reliable system.
