Switcheo TradeHub, the flagship protocol of Switcheo Labs, is being renamed to Carbon in order to better convey the protocol’s main goals of becoming the core of all decentralized financial ecosystems, and being highly connective in a multi-chain world. This shift also uncouples the protocol from Switcheo Labs’ brand identity, signalling the development entity’s commitment to true decentralization of the layer 2 protocol. To further disambiguate the protocol from any of Switcheo’s likeness, Switcheo has also been renamed to Switcheo Labs.

Carbon is an entirely new chain that will be “relaunched” from a new genesis block and move the protocol’s identifier from switcheo-tradehub-1 to carbon-1. In spite of this change, Carbon will continue to encompass the revolutionary characteristics of Switcheo TradeHub and more. For one, Carbon’s launch will be marked by the highly-anticipated Stargate Upgrade that brings major performance, composability and interoperability improvements to the layer 2 DeFi protocol.

Carbon is a permissionless protocol that seeks to enable any type of financial transaction to occur at low costs and at high speeds, without the need of trusted intermediaries, and as a springboard for launching any kind of decentralized financial market.

As part of the rebranding, a new website for the Carbon protocol has been launched and will serve as the first touchpoint for validators, developers and users. The website comes with a robust roadmap and reflects the refined positioning of Carbon, as detailed below!

Why Carbon?

The core of all things DeFi

The carbon atom is the universal building block of life and the most abundant element in the world. Similar to how it binds and connects with other elements to form the compounds that make up all of life on earth, the Carbon protocol aims to sit at the core of various ecosystems in the multi-chain world, connecting and breathing life into them.

Carbon mirrors three integral properties of the carbon element that make it vital to life - it is highly connective, versatile and stable.  

Carbon-12’s molecular structure allows it to bond with many other elements to form a myriad of compounds. Similarly, the Carbon protocol powers interoperability between siloed blockchain networks, connecting and binding them through cross-chain transactions and more. Already, the protocol is integrated with four chains - Ethereum, Neo, Binance Smart Chain and Zilliqa, with more in the pipeline!

Interoperability between blockchain networks is essential for greater exchange of value within the DeFi ecosystem. Carbon’s ability to power cross-chain capabilities across any sovereign chain allows for boundless collaboration and innovation to occur in a truly open and decentralized manner.

Just as the carbon atom exists in numerous forms like diamond & graphite, Carbon embodies versatility by being able to adapt and form the foundations of any type of financial construct. Envisioned to be the building block of DeFi ecosystems, Carbon’s architecture utilizes the Cosmos-SDK as an underlying technology and is highly composable, thereby allowing anyone to integrate with or build upon the protocol.

Compounds of the carbon element such as carbon steel and carbon fibre also have many important and purposeful uses. Similarly, the permutations & possibilities of useful innovations that can be built with Carbon are endless. Some novel use-cases that Carbon can power include AMM-backed orderbooks, decentralized central limit orderbooks (CLOBs), derivatives markets and unequal pool weights. These capabilities can already be seen in action on layer 2 derivatives DEX, Demex.

The carbon element is known to be extremely stable once bonded, another attribute that Carbon mirrors. Carbon affords security to users by being a specialized chain that is secured by a large network of validators, ensuring all transactions are legitimate and safe.

Unlike general-purpose blockchains, Carbon was developed specifically for trading and does not permit arbitrary execution of smart contracts. This means the entire blockchain is highly-optimized for trading-related execution paths while minimizing the number of possible attack vectors on the blockchain.

What to expect

The Testnet upgrade from Switcheo TradeHub to Carbon is happening today, while the Mainnet launch is slated to occur once all current validators are prepared!  

Carbon launch details

During Mainnet migration, the chain will be halted to allow validators and Switcheo Labs core developers to migrate the old nodes to the new Carbon nodes. Validators will be utilizing Carbon’s new genesis file to complete the upgrade. Once more than 67% validators have upgraded to the new Carbon chain, the new chain will start producing blocks.

As the chain will be halted, all transactions using Switcheo TradeHub on platforms such as ZilSwap (i.e. bridging) and Demex (i.e. trading, deposits, withdrawals, liquidity pooling) will be temporarily disabled during the migration process. All funds will remain safe as Switcheo Labs core devs and validators work to ensure a smooth transition to the new Carbon chain. The upgrade will not affect Layer 1 smart contracts or cross-chain state and will resume seamlessly after the migration.

The Switcheo Labs team will provide constant updates on the migration progress on Switcheo Labs’ Twitter and Telegram.

Updated sites with the corresponding information and data from Carbon can be found below:

  1. Carbon Website - main Carbon website
  2. Carbon Forum - community forum for discussion of governance proposals
  3. Carbon Guide - an overview of the Carbon protocol
  4. Carbon Scan - coming soon
  5. Carbon API docs - coming soon
  6. Carbon Migration Guide - step-by-step Testnet migration guide for validators
  7. Carbon Migration Guide - coming soon for developers

User Interfaces (UIs)

User interfaces such as Demex and Carbon Scan (new Carbon block explorer) will be migrated to the new Carbon protocol. Trades and transactions will be executed on the new Carbon chain when the Mainnet is launched.

SWTH Token

The SWTH token will remain the native, governance token of Carbon. Following Carbon’s launch, upgrades such as the new ICS-2 token standard will be possible.


Envisioned to be a fully community-owned development, anyone is empowered to enact change and seek improvements to Carbon via the protocol’s on-chain governance feature. Governance will continue to be powered by the SWTH token, enabling stakeholders to make key decisions that drive growth of the protocol.

Historical Data

Moving forward, some historical data will only be accessible on Switcheo Tradescan (legacy) as Carbon is a new chain and will not hold any transaction data (only state data is migrated). Open positions, orders, liquidity pools and balances on Switcheo TradeHub will not be affected and will be visible on Carbon.

More to come

Switcheo TradeHub was introduced over a year ago as the next evolution in decentralized cross-chain trading and has gone on to power transformative and decentralized applications such as Demex and the ZilBridge. This vision remains rooted in Carbon as the protocol continues to push the boundaries of DeFi. Already, innovative new features and capabilities are in the works to bring the protocol to the next level, equipping Carbon with unrivalled abilities to form the backbone of decentralized financial economies.

Carbon will be an open-sourced, community-driven development, and everyone is invited to join in on this groundbreaking journey.
