**_Crosschain, baby!_**

[FRACTION](https://fraction.fyi)'s transformation into the first ‘_Super_‑_xToken_’ marks a pivotal chapter in the project's journey.

It started as the second pure [SuperFluid](https://www.superfluid.finance) [SuperToken](https://docs.superfluid.finance/superfluid/protocol-overview/in-depth-overview/super-tokens) after [MIVA](https://minerva.digital/#MIVA-SuperToken) ([Minerva Wallet](https://play.google.com/store/apps/details?id=digital.minerva) SuperToken), and now FRACTION, with the support of [Connext](https://www.connext.network), has integrated [xERC20](https://xerc20.com/) token functionalities, placing it in a unique spot within the token landscape as the first one that is a _pure SuperToken_ AND an _xERC20 Token_. This integration enables FRACTION to bridge across networks such as [GnosisChain](https://gnosischain.com/), [Polygon](https://polygon.technology/), [Optimism](https://www.optimism.io/), [Arbitrum One](https://arbitrum.one/), and [BNBChain](https://bnbchain.org/en), with the addition of [Avalanche C-Chain](https://www.avax.network/) expected soon. It also serves as a testing ground for expanding MIVA to more chains next year.

> _However, it's crucial to note that FRACTION is primarily a DeFi experiment and playground,_ **_without a specific real-life use case._**

This integration marks a significant milestone in the project's multi-chain expansion efforts. Although this approach has not yet fully concluded, users can already move FRACTION between these chains using the [Connext Bridge](https://bridge.connext.network/FRACTION-from-gnosis-to-polygon?symbol=FRACTION). Additionally, a modest amount of DEX liquidity is now available on new chains, enabling aggregators like [LI.FI](https://li.fi) to offer cross-chain routes (for example via [jumper.exchange](https://jumper.exchange/?toChain=100&toToken=0x2bF2ba13735160624a0fEaE98f6aC8F70885eA61), the [Superfluid Bridge](https://app.superfluid.finance/bridge), or Metamask's Swap Feature).

### Superfluid and (pure) SuperTokens

[Superfluid](https://superfluid.finance) is a protocol on EVM blockchains that introduces the concept of programmable cash flows, [enabling users](https://app.superfluid.finance) to stream tokens in real-time on a per-second basis. Pure SuperTokens are tokens that are natively created with Superfluid's streaming payment and instant distribution functionalities, offering enhanced token utility without the need for wrapping an existing ERC20 token. → [Read more about it in their Docs](https://docs.superfluid.finance/superfluid/protocol-overview/in-depth-overview/super-tokens)

### Connext and xERC20

[Connext](https://www.connext.network) is a decentralized crosschain intent protocol for fast, secure, and interoperable asset transfers and communication across different Ethereum-compatible blockchains. [xERC20](https://xerc20.com) (ERC‑7281) is a token standard, first introduced by Arjun Bhuptani of Connext that enables Ethereum-compatible tokens to be seamlessly transferred across different blockchain networks, facilitating interoperability and reducing liquidity fragmentation. → [Read more about it in their Docs](https://docs.connext.network/usecases/xerc20)

### Dual strategy: Lockbox and Burn/Mint

The current system operates using a dual mechanism: a Lockbox Mechanism on GnosisChain, its home chain, and a burn/mint approach on the new chains. This implementation strategy strategically utilizes previously minted FRACTION on new chains, repurposing them as fast-lane liquidity within the router.

This arrangement will persist until a new Superfluid Protocol enables the burning of the Token outside the Router in the future. For more details, see the associated [Snapshot DAO proposal](https://snapshot.org/#/fractiontoken.eth/proposal/0xa6c0c161a749d68fe41161d601f76780a503ec401ce085c007e34e04fe962030) and the “[2023 Proofs](https://mirror.xyz/fractiontoken.eth/ojZsxhDGP8__840WU9-ONClWjO9k024cPV4tZHcvQAQ)” article.
