R3E Network has shipped a live API indexer for Neo N3, giving developers structured access to on-chain data through a new service at n3index.dev. The release is one of several infrastructure deliveries from Jimmy Liao, R3E Network founder and Neo core developer, in the span of two weeks, alongside a free domain name system and continued improvements.
The tools extend R3E’s growing infrastructure footprint on Neo N3, which includes the neo3scan.com block explorer launch, a Rust-based Neo implementation, and a Neo Solidity compiler project.
N3Index API
N3Index provides two integration modes at api.n3index.dev. The Indexer API offers structured JSON endpoints designed for wallets, explorers, and dApps, while the REST API exposes a raw PostgREST query layer for advanced data consumers using SQL-like URL syntax.
Core capabilities include account transaction history, NEP-17 and NEP-11 transfer tracking, contract event decoding, token holder information, daily chain analytics, and validator metadata. The service supports both MainNet and TestNet and runs on Cloudflare worker infrastructure. The homepage displays lag metrics and coverage statistics for its indexed data.
N3Index is built on top of neo3fura, the Neo N3 data indexing service that also serves as the backend for neo3scan.com. The data is synced from neo3fura to build the N3Index API layer, with added caching and DDoS protection.
.matrix domains
Liao also deployed a new domain name system for Neo N3, using the .matrix top-level domain. A notable feature is its pricing model, as domains are free to register and never expire.
The domains are implemented as transferable NFTs on a new smart contract, separate from NeoNS, the native Neo N3 domain service that launched in Sept. 2022. NeoNS domains use the .neo TLD and require annual $GAS payments for renewal, with fees ranging from 2 $GAS per year for five-character-or-longer names to 200 $GAS for three-character domains.
Liao described .matrix as primarily serving the R3E ecosystem rather than competing with NeoNS. “NNS is like a business project, it costs money to have it and maintain it,” he told Neo News Today. “.matrix is mainly only for R3E ecosystem, anyone can get one, and own forever.”
The system has been integrated into neo3scan.com as a first-class identifier. When an address is bound to a .matrix domain, the explorer displays the domain name instead of the raw address throughout the interface. NeoNS domains are also supported on neo3scan, meaning the explorer now recognizes two independent naming systems.
Registration currently requires a Neo N3 wallet. EVM wallet users cannot register .matrix domains yet as the account abstraction features are not yet fully complete.
