About Osmosis

Osmosis launched its mainnet on June 19, 2021. It is built with the Cosmos SDK and uses CometBFT (Tendermint) BFT consensus, giving instant single-block finality with block times of roughly 5-6 seconds.

OSMO uses 6 decimals (base denom uosmo). Osmosis specializes in customizable AMM pools and cross-chain swaps over IBC. Tooling includes the Cosmos SDK, CosmJS, and the Osmosis CLI/LCD and Tendermint RPC.

Common Use Cases on Osmosis

  • AMM liquidity pools
  • Cross-chain (IBC) swaps
  • Supercharged/concentrated liquidity
  • Staking and governance
  • Cosmos asset trading

Osmosis Ecosystem

Osmosis is a core Cosmos DEX connected via IBC to chains such as the Cosmos Hub, Celestia, and Injective, with apps like Mars Protocol and Levana deployed in its ecosystem.

Quick Start: Connect to Osmosis

cURL

curl -X POST https://rpc.swiftnodes.io/rpc/osmosis?key=YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"getHealth","id":1}'

Note: Osmosis uses its own RPC methods. Refer to the official Osmosis documentation for available methods.

Bridging to Osmosis

Native cross-chain transfers use IBC; external assets reach Osmosis through bridges such as Axelar and the Squid router.

Frequently Asked Questions: Osmosis

Does Osmosis have an EVM chain ID?

No. Osmosis is a non-EVM Cosmos SDK chain and does not use an EVM chain ID. It identifies its network with a Cosmos chain-id string (osmosis-1 for mainnet).

How is Osmosis queried?

Osmosis is queried over CometBFT (Tendermint) RPC and the Cosmos REST/gRPC (LCD) interfaces, typically via CosmJS, rather than Ethereum JSON-RPC.

How many decimals does OSMO have?

OSMO has 6 decimals; the base denomination is uosmo, where 1 OSMO equals 1,000,000 uosmo.

Osmosis guides from the blog

  • Osmosis RPC: The Cosmos DEX as a Chain ModuleOsmosis is the leading Cosmos DEX — a non-EVM Cosmos SDK chain (osmosis-1) on CometBFT. The twist for developers: the AMM isn't a smart contract you eth_call, it's a native chain module you query over Tendermint RPC, REST, or gRPC. Here's how to read pools, prices, and swaps.
