# What is Allbridge Classic? {% hint style="warning" %} ## Allbridge Classic is deprecated and will be stopped in mid-2026. You can find information on our current bridge Allbridge Core [here](https://docs-core.allbridge.io/). {% endhint %} ## Introduction ### What is a blockchain bridge? A blockchain bridge is a connection that allows tokens and/or arbitrary data to be transferred from one chain to another. Both chains may have different protocols, rules, and governance models, but the bridge creates a reliable mechanism for both chains to interoperate. There are a lot of diverse bridge designs, but they may generally be classified into two categories: more centralized bridges that rely on trust or federation, and more decentralized, trustless bridges. ### What is Allbridge Classic? Allbridge Classic is a simple, modern, and reliable way to transfer assets between different networks. It is a bridge between both EVM and non-EVM compatible blockchains. Our mission is to make the blockchain world borderless by providing a tool to freely move assets between various blockchains. ### **The advantages of Allbridge Classic** #### 1. Versatile bridge Allbridge Classic enables connections between both EVM and non-EVM compatible blockchains. {% content-ref url="/pages/-Mfb\_BDZOMkmjmKA0E7r" %} [Networks and tokens](/allbridge-overview/networks-and-tokens.md) {% endcontent-ref %} #### 2. Fast transfers Our underlying technology allows the transfers to be as fast as a normal transaction on a given blockchain. Every transfer involves 2 transactions: one, from the source blockchain, and the second one on the destination chain. In the case of Allbridge Classic, the transaction takes only as much time as is required by a given blockchain to confirm it. #### **3. Architecture flexibility** Allbridge Classic supports a number of different transfer types. Users may send Native tokens and receive either Native or Wrapped (minted) tokens on the destination blockchain. They may also send Wrapped tokens from the source blockchain and receive Native or Wrapped tokens on the destination chain. {% content-ref url="/pages/ZTayR53QMN2EqZ3ct0RP" %} [Under the hood of Allbridge Classic](/allbridge-overview/under-the-hood-of-allbridge-classic.md) {% endcontent-ref %} #### **4. Dynamic fees** The dynamic fees system allows Allbridge Classic stakers to decrease the cost that they pay for transferring assets. The bridge fee is paid before the transaction is sent, thus staking on the source blockchain allows to reduce the bridging fee. {% content-ref url="/pages/zPHgi1ISkMWG9SdHFhw5" %} [Bridge Fee](/allbridge-overview/bridge-fee.md) {% endcontent-ref %} {% content-ref url="/pages/cFYj8ZtgCNu0PE017XoC" %} [ABR staking](/allbridge-classic-staking/abr-staking.md) {% endcontent-ref %} #### 5.
