# Overview (Omniston)

Omniston is a liquidity aggregation protocol for swaps on TON and cross-chain swaps. It collects quotes from connected liquidity sources and returns the best available terms through a single integration.

## What is Omniston?

Omniston aggregates liquidity from connected sources to provide:

* Best available terms for a requested swap
* Reduced slippage on large trades
* A single integration for TON and cross-chain swaps
* Support for referral fees and custom integration flows

## How It Works

1. **Request**: User requests a swap through Omniston
2. **Aggregation**: Protocol queries multiple liquidity sources
3. **Selection**: Omniston returns the best available quote for the requested swap.
4. **Execution**:The selected quote is settled either on TON or through a cross-chain flow where the output asset is delivered on the destination blockchain.

## Liquidity Sources

* **AMM DEXs**: STON.fi and other TON DEXs
* **RFQ resolvers**: Resolvers that provide executable quotes
* **Cross-chain**: Liquidity accessed through HTLC-based atomic swaps

## Key Benefits

### For Users

* Access to assets available through connected liquidity sources
* Best available terms for the requested swap
* Support for TON and cross-chain swaps
* Access to deep liquidity

### For Developers

* Single SDK for all liquidity
* WebSocket and gRPC APIs for custom integrations
* One RFQ flow for TON and cross-chain swaps
* Built-in price optimization

### For Resolvers

* Direct market access
* Flexible fee structure
* Programmatic trading
* MEV opportunities

## Supported Chains

Omniston supports the following blockchains:

* Arbitrum
* Avalanche C-Chain
* Base
* BNB Chain
* Ethereum
* Polygon
* TON

For `chain_id` values, chain matching rules, and cross-chain implementation details, see [Omniston API v1beta8](/developer-section/omniston/v1beta8.md) and [How Omniston Works](/developer-section/omniston/how-omniston-works.md).

## Integration

Omniston supports three integration approaches:

1. **SDK (recommended)** — easiest way to add swaps ([Node.js](/developer-section/omniston/sdk/nodejs.md) / [React](/developer-section/omniston/sdk/react.md)).
2. **WebSocket (JSON-RPC)** — low-level API for custom integrations.
3. **gRPC (TLS)** — primary low-level API for backend integrations and resolvers.

## Endpoints & Environments

### Production

* WebSocket (JSON-RPC): `wss://omni-ws.ston.fi`
* gRPC (TLS): `omni-grpc.ston.fi:443`
* Demo site: [omniston.ston.fi](https://omniston.ston.fi)

### Sandbox (public testing)

* WebSocket (JSON-RPC): `wss://omni-ws-sandbox.ston.fi`
* gRPC (TLS): `omni-grpc-sandbox.ston.fi:443`
* Demo site: [omniston-sandbox.ston.fi](https://omniston-sandbox.ston.fi)

> ⚠️ gRPC endpoints are **host:port** targets over TLS and are not HTTP REST URLs. Do not use `https://...` as if it were a REST API.
