ArcWorld is one developer's app suite on Arc testnet, not a directory. Confirmed as of 2 Sep 2026. > ArcWorld (arcworld.io) is a single developer's collection of Arc-testnet apps and mini-games — not, despite the name, an ecosystem directory. It has more of the standard trust signals than most projects in this cluster: a public developer, docs, and a GitHub link. What's still unconfirmed is set out below. **Builds on Arc:** One developer's suite of Arc-testnet apps — NFT mint, virtual card, land, games — not a directory. · **Role:** Deploys ## What ArcWorld says about itself ArcWorld describes itself as "a Web3 platform built on Arc Network" that "develops various applications and tools to help users experience Arc Network in a simpler and more interactive way." Despite the name suggesting a broad ecosystem hub, the site is explicit that it is one team's product line: it's built by a developer using the handle Wentyom (@wentyom on X). The listed apps span a genesis NFT collection (ArcWorld Key), an identity tool called Passport, a virtual USDC card interface, a virtual-land grid called Arc Land, a parametric weather-insurance concept called Arc Climate Pay, nine educational mini-games under Arc Games, a set of testnet utilities (faucet, balance checker, quick transfer), and a community news feed called Arc Times. The site states its products are "fully on-chain" and "non-custodial," and confirms it runs on Arc Testnet, chain ID 5042002 — matching Arc's own published testnet chain ID. ## What's verifiable as of 2 Sep 2026 ArcWorld's site is live and provides more of the standard checkable artifacts than most entries in this cluster: a documentation subdomain (docs.arcworld.io), a linked GitHub repository, an X account tied to a named individual developer handle, and a Discord community. That combination — named builder, public docs, linked code repository — is a genuinely stronger public-disclosure posture than the launchpads and DEXs covered elsewhere in this cluster, even though it does not amount to an audit or a funded-team disclosure. The site's own claim that it operates on Arc Testnet with chain ID 5042002 is internally consistent with Arc's published testnet parameters, which is a small but real corroborating detail. ## What is not yet confirmed as of 2 Sep 2026 Whether "Wentyom" corresponds to a verifiable real-world identity, a company, or a solo pseudonymous builder is **not yet confirmed as of 2 Sep 2026** — an X handle alone does not establish legal identity. No security audit of ArcWorld's contracts was found. Whether any of its apps — the virtual card, the land grid, the climate-pay concept — have real economic value moving through them versus functioning as testnet demonstrations is **not yet confirmed as of 2 Sep 2026**. Funding, if any, is **not yet confirmed as of 2 Sep 2026**. ## Status and on-chain checks **Status:** Testnet only, per the site's own chain-ID claim (5042002). **On-chain checks (Deploys role, where applicable per app):** Contract — none published for any individual app. Audit — none found. ## How to check it yourself Because ArcWorld actually publishes docs and a GitHub link, this is one of the more straightforward projects in this cluster to check yourself: read docs.arcworld.io directly, and check whether the linked GitHub repository shows active, recent commits versus a stale one-time upload — commit history is one of the more reliable signals for a small pseudonymous project.

Sources: - [ARC WORLD](https://arcworld.io/) ## Questions **Is ArcWorld a directory of Arc projects?** No — despite the name, it's explicitly one developer's own suite of applications, not a listing of other projects. **Who builds ArcWorld?** A developer using the handle Wentyom (@wentyom on X), per the site's own attribution. No further verified identity was found. **Does ArcWorld have real audited contracts?** No audit was found as of 2 Sep 2026, though the project does publish docs and a GitHub repository, which is more than most comparable projects in this cluster. **Is ArcWorld live on Arc mainnet?** No — its own site states it runs on Arc Testnet; Arc mainnet itself launches 16 September 2026. **What is the ArcWorld Key NFT?** Described on the site as a free genesis-collection mint tied to the platform. Its terms and any future utility beyond that description are not yet confirmed as of 2 Sep 2026.
