Hello Moon

Hello Moon is a blockchain infrastructure company that sells Solana developers the plumbing to read chain data and land transactions quickly: a transaction-landing service called Lunar Lander, shared and dedicated RPC nodes, gRPC streaming, stake-weighted transaction routing and staking. It started in 2021 as a Solana NFT and DeFi analytics platform. Since then it has moved toward lower-level infrastructure and added Avalanche support.

From analytics explorer to infrastructure provider

Hello Moon's early product was a public analytics explorer for Solana NFTs and DeFi. The explorer tracked NFT floor prices, marketplace volume, whale and influencer wallet activity, and suspected wash trading, and it showed sample wash-trade transactions with the wallets, prices and timestamps involved. Pages from that explorer, such as per-collection wash trading reports, are still indexed on hellomoon.io. The company described itself as "a Solana developer platform that helps companies engage directly with on-chain data at Solana speeds," with real-time feeds covering DeFi, NFT and transfer events, according to its profile on the Blockchain Capital portfolio job board.

The current website calls Hello Moon "Crypto's Most Powerful Developer Platform." It lists infrastructure, staking and data solutions for Solana and Avalanche, dedicated nodes, and a developer dashboard. The developer documentation now covers RPC access, dedicated nodes, gRPC streaming, stake-weighted quality of service (SWQoS) and Lunar Lander rather than the older NFT datasets.

Lunar Lander: transaction landing

Lunar Lander is Hello Moon's service for getting Solana transactions confirmed quickly. The process has four steps:

1. The developer builds a normal Solana transaction.
2. The developer adds a transfer instruction that sends a tip of at least 0.001 SOL to one of Hello Moon's designated tip accounts.
3. The transaction goes to the nearest of twelve regional endpoints: Frankfurt, Amsterdam, London, New York, Chicago, Dallas, Ashburn, Los Angeles, Singapore, Sydney, Dubai or Tokyo.
4. Hello Moon's infrastructure forwards the transaction to the network.

Pricing is based on success. Hello Moon says users pay only when a transaction lands, and higher tips get higher priority during congestion.

Lunar Lander accepts transactions in four ways:

• Standard submission over HTTP.
• QUIC submission, which Hello Moon presents as a lower-latency path with faster connection setup.
• Batch send, which pushes many transactions in one request to reduce client and network overhead.
• Send bundle, which submits a group of transactions for atomic, sequential execution: either all of them land or none are committed.

Transactions can also be sent in raw binary format to cut serialisation overhead. Hello Moon publishes an official Rust QUIC client under the Apache 2.0 licence. The client handles connection management with jittered exponential backoff on reconnects, creates client certificates from API keys, and supports both fire-and-forget and acknowledged submission. It works with legacy, v0 and v1 transactions of up to 4,096 bytes. The repository also describes MEV protection options that are signalled through custom X.509 certificate extensions.

RPC nodes and gRPC streaming

Hello Moon runs a shared RPC fleet, which it describes as "a fleet of multiple machines that are shared by our different users." The fleet supports HTTP and WebSocket methods. Historical and archival RPC data is listed as unsupported, and the RPC quickstart also documents an Avalanche mainnet endpoint.

Dedicated RPC nodes are machines reserved for a single customer. They are sold on monthly or annual subscriptions with unlimited calls and no per-request credit charges. Customers set them up from the developer dashboard, which shows each node's URL, status, region and access tokens. Each node comes with HTTPS, WSS and gRPC endpoints. The docs also cover a dedicated node VM option.

gRPC streaming uses the Yellowstone gRPC (Geyser) interface and requires a dedicated node. Clients can subscribe to:

• slot updates
• account changes, filtered by owner or data
• transactions, filtered by vote status, failure status, signature and included or excluded accounts
• full blocks and block metadata

Unary calls for the latest blockhash, block height, current slot and node version are also available.

Stake-weighted QoS and staking

Hello Moon operates a voting validator on Solana and uses its stake to offer a Stake-Weighted Quality of Service plugin for dedicated-node customers. Under Solana's SWQoS rules, validators with more stake get a proportionally larger share of connection capacity to the block leader. Hello Moon routes customer transactions through a dedicated /swqos/ endpoint so they travel over its staked connection, with the aim of improving inclusion rates during congestion. The default allowance is 5 transactions per second, and customers contact the team for more bandwidth.

The same validator underpins Hello Moon's staking business. Its website lists staking services for Solana and Avalanche, and it hosts an Avalanche staking page.

Team and backing

The Blockchain Capital job board lists Hello Moon as a New York-based company founded in 2021, with 1–10 employees at the Series A stage. Its presence on that board indicates it is a Blockchain Capital portfolio company. The website describes the team as "crypto veterans" with experience "processing billions in daily volume across multiple market cycles." It displays logos of organisations it says use its services, including Messari, The Block and the Solana Foundation. Hello Moon has not published a full funding history on its own site, and this profile does not repeat figures that appear only on data aggregators.

Role in the Solana ecosystem

Hello Moon competes in Solana's infrastructure layer alongside other RPC and transaction-delivery providers. The market it serves is trading firms, bots and applications that need low-latency data and reliable transaction inclusion. Its main product lines, as of 2026, are:

• tip-based landing through Lunar Lander
• dedicated nodes with Yellowstone gRPC
• SWQoS routing backed by its own validator stake

Its official site, documentation and X account (@HelloMoon_io) were all active in 2026.
