Lumera Protocol is a Cosmos SDK Layer 1 blockchain. The chain coordinates requests, payments, and proofs, while economically bonded SuperNodes perform storage, verification, and retrieval. You reach all of it through SDKs, smart contracts, or plain REST and gRPC. This page gets you connected to a network and points you at the right section for what you are building. It takes a few minutes and needs nothing but curl.
This page is for application developers. Node operators can start with the validator quickstart or the SuperNode quickstart.

​
What you can build

Lumera exposes four surfaces. Most applications use more than one.

​
Choose a network

Build on testnet first. Testnet tokens are free and the EVM is available there today. Public endpoints are rate limited. Run your own node or use a dedicated provider for production traffic. See Networks and endpoints for genesis files and seed nodes.

​
Connect to the network

1

Confirm you can reach the chain

Query the RPC endpoint and check which network answers.
You should see lumera-testnet-2. If you get nothing back, the endpoint is rate limiting you or is down. Try another provider from Networks and endpoints.
2

Check the running version

The REST endpoint reports the application version the network is on.
Match this version when you install lumerad or pin an SDK. Mainnet and testnet run different versions.
3

Create an address

Lumera uses bech32 addresses with the lumera prefix. Get one from Lumera Hub, from a Cosmos wallet such as Keplr or Leap, or from the CLI.
Save the mnemonic somewhere safe. See the lumerad CLI reference for keyring backends.
4

Fund the address

Most operations cost gas, and protocol services escrow a service fee on top. Request testnet LUME from the faucet, then confirm the balance arrived.
Balances are in ulume, where 1 LUME is 1,000,000 ulume.
You are connected. Pick the path that matches what you are building.

Choose your path

Store data permanently

Use Cascade to store files that stay retrievable. Pay once at upload and the network keeps the data available.

Deploy a smart contract

Deploy Solidity through the Cosmos EVM with MetaMask and Remix, or Rust through CosmWasm.

Build with an SDK

JavaScript for browsers and Node.js, Go for backends with direct SuperNode access, and Rust for system integrations.

Query the chain

Read chain state, SuperNode metrics, and Action metadata over REST, gRPC, and JSON-RPC.
