# Overview
Rubic's Best Rate Finder for users and dApps aggregates 340+ DEXs, bridges, intent protocols and privacy solutions across 70+ blockchains.
Rubic was born in 2020, at the peak of DeFi Summer, when cross-chain trading was fragmented and every blockchain felt like its own isolated island.
For the past five years, we’ve been building a solution to connect those islands into a single, seamless experience. One interface. Unified liquidity. The smoothest possible user journey across chains.
Rubic’s Best Rate Finder was among the first to step into this space, aggregating fast, cost-efficient, and secure DEXs, bridges, intent-based protocols, privacy solutions and other aggregators. All within one ecosystem.
The mission has always been simple: make cross-chain activity effortless, accessible, and truly unified.
Now, you don't need to roam around Web3 and compare DEXs and bridges for rates - Rubic does it in seconds. We enable swaps on and across 70+ chains, supporting 70,000 tokens and over 1,000,000 pairs, all with the best routes across 340+ DEXs, bridges, intent protocols, privacy solutions.
Rubic has **already simplified cross-chain trading**. **Now we’re doing the same for privacy.**
We prioritise integrating emerging chains **from day one**, often before giant DEXs and on-chain aggregators do, so users can access the latest and most in-demand networks. And on top of that, we **add new tokens from day** **one** and **onboard tokens on demand**.
Rubic offers **1:1 stable-to-stable swaps** with no hidden fees, no slippage, just pure value.
With whale-friendly and low-barrier swaps, users can start trading from just \$0.50, **no entry barriers**, while also executing **multi-million-dollar transactions** at the best rates.

## **Focusing on Chain Abstraction**
| **Chain Abstraction Principles** | **Rubic** |
| -------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Asset Management Abstraction** | Rubic’s **Best Rate Finder App** now features **“All Chains”**, a powerful addition that enhances the chain abstraction experience, allowing users to **monitor all their tokens across multiple networks in one place**. Besides, this new category provides a seamless way to explore the **most popular tokens, top gainers & losers across all supported blockchains** in a single view. Furthermore, users can now easily locate a specific token on **every available chain**, simplifying cross-chain asset discovery and trading. |
| **Transaction Abstraction** | Thanks to Rubic’s smart routing feature, users can execute cross-chain token swaps in **a single multi-hop transactio**n – eliminating the hassle of manually navigating multiple DEXs and bridges. |
| **Token Bridge Abstraction** | As the Best Rate Finder, Rubic aggregates 70+ blockchains and 360+ **DEXs, bridges, & intent-based protocols** enabling seamless cross-chain interactions. By integrating bridging and protocol actions into a single transaction, Rubic simplifies the process with automated relayers that execute user intents effortlessly. **Aggregated bridges, DEXs & intent-based protocols handle all the work for users**, whether it’s a [cross-chain or on-chain trade](https://rubic.exchange/blog/on-chain-vs-off-chain-transactions-in-crypto/). |
| **Multi-Chain Abstraction** | On Rubic, users can seamlessly swap assets to, from, and across EVM, non-EVM, and Layer2 chains, all within a single interface. When swapping to non-EVM chains, for example, one doesn’t need to log in to a non-EVM wallet (like for Bitcoin, Ton, etc.) and simply enter the receiver’s wallet address on a non–EVM chain without needing to log in twice. |
## **0% Protocol Fees**
Rubic now offers **zero fees** for swaps under \$100! Most on-chain swaps involving stablecoins or native tokens are also completely free.
Additionally, bridging **\$USDT** from popular EVM chains to **TRON** and all swaps with **Solana** are now entirely fee-free on Rubic.
For larger swaps or other trade types, fees will depend on the specifics of your transaction. Enjoy seamless and cost-effective swapping with Rubic!
## **Prioritizing Security**
Rubic is a decentralized cross-chain and on-chain aggregator. KYC is not required for starting an exchange on the platform.
Deposit-based providers like ChangeNOW, SimpleSwap, Changelly, Exolix, Quickex are partially centralized. KYC may be required if a transaction conducted via such a provider is marked as suspicious by the provider's automated risk prevention system. In such cases, KYC is carried out on the provider's side. Please find more details [here](https://dev-docs.rubic.exchange/rubic/overview/support-kyc).
Rubic’s tech remains sustainable and secure: your funds always stay in your wallet and never on [app.rubic.exchange](http://app.rubic.exchange). Every transaction is conducted via API by sending calls to providers’ smart contracts. You can always count on 24/7 support. [Learn more](https://dev-docs.rubic.exchange/rubic/overview/security).
