R3E Network has released 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 many infrastructure deliveries from Jimmy Liao, founder of R3E Network and core developer of Neo, in the span of two weeks, in addition to a free domain name system and ongoing improvements.
The tools expand R3E’s growing infrastructure footprint on Neo N3, including the launch of the neo3scan.com block explorer, a Rust-based Neo implementation, and a Neo Solidity compiler project.
N3Index API
N3Index offers two integration modes on api.n3index.dev. The Indexer API provides 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 decryption, token holder information, daily chain analytics, and validator metadata. The service supports both MainNet and TestNet and runs on the Cloudflare working infrastructure. The home page shows latency statistics and coverage statistics for the 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 additional caching and DDoS protection.
.matrix domains
Liao has also implemented a new domain name system for Neo N3, using the .matrix top-level domain. A notable feature is the pricing model, as domains are free to register and never expire.
The domains will be deployed as transferable NFTs based on a new smart contract, separate from NeoNS, the native Neo N3 domain service that launched in September 2022. NeoNS domains use the .neo TLD and require annual registration $GAS payments for renewal, with costs ranging from 2 $GAS per year for names of five characters or longer up 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 and maintain it,” he told Neo News Today. “.matrix is mainly just for the R3E ecosystem, anyone can get one and own it forever.”
The system is integrated into neo3scan.com as a first-class identification tool. 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 yet register .matrix domains because the account abstraction features are not yet fully completed.
