Stratis is pleased to provide an update on the development activities that have taken place over the past 3-Months. It’s been an exciting time for Stratis, with the launch of the STRAX Blockchain enhancements, to the announcement of a

The launch of wSTRAX

Stratis InterFlux now fully supports the Ethereum blockchain, enabling seamless transitions from the native STRAX Token to wSTRAX. The launch of the wSTRAX ERC-20 token on the Ethereum blockchain will coincide with a newly created liquidity pool on UniSwap between wSTRAX and ETH, enabling STRAX to take full advantage of UniSwaps automated liquidity protocol. Stratis has received confirmation of USD 150,000 being made available for the wSTRAX/ETH pool, allowing token holders to take immediate advantage of the UniSwap DEX. The wSTRAX token is not limited to UniSwap and can be leveraged, integrated and utilized on any DeFi solution or platform available on the Ethereum blockchain.
The two contracts controlling the issuance of wSTRAX on the Ethereum blockchain can be found below:

This process of transitioning from STRAX to wSTRAX is made seamless through integration into the latest STRAX Wallet offerings. Navigate to the send pane and select InterFlux as a destination to simply “swap” STRAX for wSTRAX in a trustless manner. Please be aware that there is a minimum STRAX Token amount enforced due to high fees on the Ethereum blockchain. 
This release is accompanied by the latest STRAX Wallet release, available for all major operating systems. Download links can be found on the wallet page.
Join Stratis’s ever-growing community to discuss the further advantages of the developments mentioned above and how the ‘wrapping’ of other blockchain tokens can benefit Stratis Blockchain Technologies.

The Stratis Interflux wSTRAX rollout on Ethereum has begun

Stratis is ecstatic to reveal that the wSTRAX (Wrapped STRAX) Token is now available on the Ethereum Blockchain! Wrapped tokens are a valuable source of liquidity and flexibility for blockchain interoperability. Over time, any network’s available throughput and general fee levels will fluctuate. Having wrapped tokens available on a separate blockchain network allows transacting to occur via alternate channels. Wrapped tokens also have access to the respective capabilities of the networks they exist on.
wSTRAX implements a wrapped token on the Ethereum network, leveraging the ubiquitous ERC-20 standard for token contracts. Each wSTRAX is equivalent in value to 1 STRAX. wSTRAX is created by the InterFlux MasterNodes collaboratively, rather than any single entity being responsible for minting the tokens. When a request is made to transfer STRAX to its wSTRAX equivalent on the Ethereum network, the transaction is autonomously detected and processed. Enabling the minting of required wSTRAX tokens and distribution handling to the respective Ethereum address to be undertaken seamlessly.
The deployment is made possible through the deployment of two contracts on the Ethereum Blockchain,

Wrapped STRAX

Wrapped tokens are a valuable source of liquidity and flexibility for blockchain interoperability. Over time, any network’s available throughput and general fee levels will fluctuate. Having wrapped tokens available on a separate blockchain network allows transacting to occur via alternate channels. Wrapped tokens also have access to the respective capabilities of the networks they exist on.

Each wSTRAX is equivalent in value to 1 STRAX. wSTRAX is created by the InterFlux MasterNodes collaboratively, rather than any single entity being responsible for minting the tokens. When a request is made to transfer STRAX to its wSTRAX equivalent on the Ethereum network, the transaction is autonomously detected and processed. Enabling the minting of required wSTRAX tokens and distribution handling to the respective Ethereum address to be undertaken seamlessly.
A minting transaction is submitted to the Stratis InterFlux Ethereum Masternode MultiSig wallet contract. A majority decision is required to confirm the transaction’s validity before being broadcasted to the Ethereum network. Once this happens, the wSTRAX will appear in the destination account’s balance and be transacted with any other ERC-20 token.
The initial version of Stratis InterFlux includes transacting with a wrapped STRAX token on the Ethereum network.
For this to be accomplished, the corresponding STRAX is secured by the Federation MultiSig for the wSTRAX token’s lifetime.

  1. Conversion transaction received as a Cross-Chain-Transfer from the STRAX blockchain.
  2. The Stratis InterFlux Gateways(s) detect receipt of this transaction.
  3. One of the InterFlux Gateways submits a token minting request transaction to the Ethereum InterFlux Hub contract and signs it
  4. A quorum of the other Stratis InterFlux Gateways sign this transaction.
  5. When the transaction is sufficiently signed the minting request is submitted to the ERC20 contract, creating new wSTRAX tokens and allocating them to the account specified in the conversion transaction.
  6. The wSTRAX ERC20 token can be transacted as normal by ordinary Ethereum wallets and accounts.
  7. Conversion from wSTRAX back into CRS or STRAX is accomplished by submitting a burning request to the ERC20 contract for the desired amount, specifying the target InterFlux Hub address.
  8. The InterFlux Gateways detect the burn request on the Ethereum network and release the corresponding funds from the InterFlux Gateway wallet to the target address.


It should be noted that the system as described ensures that every wSTRAX token is backed by its equivalent value. In other words, there can’t be more wSTRAX in existence than the funds in the InterFlux Gateway wallet. In the future, CRS will be convertible to wSTRAX via a conversion contract on the InterFlux Hub network.

Architecture Overview

To allow blockchain interoperability between networks, a mechanism is required for bridging the networks. The InterFlux architecture will consist of multiple gateways that interface with a node on both interoperating networks. A high-level overview can be seen below.

The gateways listen for interoperability requests initiated against the InterFlux contracts on each network. For example, suppose an Ethereum node needs to invoke a Stratis C# Smart Contract method. In that case, it sends a transaction to the Ethereum InterFlux contract with the details of the invocation (e.g. Cirrus contract address, method name, parameters).
Once the invocation request is received, one of the Stratis InterFlux Gateways actions a transaction on the interconnected network. If there are any applicable return values, these are stored in the transaction receipts. The gateway then makes a further transaction on the original network to store the interoperability request results.

Roll out schedule

Sunday(14/02/21)-Monday(15/02/21): Interflux Masternode setup.
Tuesday(16/02/21): Interflux enabled wallet release (Ethereum Ropsten).

Please note this schedule is dependent on the results of the community testing.

Stratis InterFlux – Ethereum Interoperability

We are pleased to announce that we have now extended the blockchain support for Stratis InterFlux to include Ethereum. Opening the door to many more use-cases and enabling Stratis Technologies to leverage deployed use-cases and products on the Ethereum blockchain.

Wrapped STRAX

The initial version of Stratis InterFlux includes the ability to transact with a wrapped STRAX token on the Ethereum network.
For this to be accomplished, the corresponding STRAX is secured by the Federation MultiSig for the lifetime of the wSTRAX token.
Token lifecycle:

  1. Conversion transaction received as a cross-chain transfer from the STRAX blockchain.
  2. The MultiSig masternodes detect receipt of this transaction
  3. One of the MultiSig nodes submits a token minting request transaction to the Ethereum MultiSig wallet contract and signs it
  4. A quorum of the other MultiSig nodes sign this transaction
  5. When the transaction is sufficiently signed the minting request is submitted to the ERC20 contract, which creates new wSTRAX tokens and allocates them to the account specified in the conversion transaction
  6. The wSTRAX ERC20 token can be transacted with as normal by ordinary Ethereum wallets and accounts
  7. Conversion from wSTRAX back into CRS or STRAX is accomplished by submitting a burn request to the ERC20 contract for the desired amount, specifying the target Cirrus address
  8. The MultiSig nodes detect the burn request on the Ethereum network and release the corresponding funds from the MultiSig wallet to the target address

It should be noted that the system as described ensures that every wSTRAX token is backed by its equivalent value. In other words, there can’t be more wSTRAX in existence than the funds in the MultiSig wallet.

In the future, CRS will be convertible to wSTRAX via a conversion contract on the Cirrus network.

Proposed Architecture Overview

To allow blockchain interoperability between networks, a mechanism is required for bridging the networks. At a high level, the InterFlux architecture will consist of multiple gateways that interface with a node on both interoperating networks.

The gateways listen for interoperability requests initiated against the interop contracts on each network. For example, suppose an Ethereum node needs to invoke a Cirrus smart contract method. In that case, it sends a transaction to the Ethereum interop contract with the details of the invocation (e.g. Cirrus contract address, method name, parameters).
Once the invocation request is received, one of the masternodes actions a transaction on the opposite network. If there are any applicable return values, these are stored in the transaction receipts. The gateway then makes a further transaction on the original network to store the interoperability request results.
The Stratis InterFlux source is now available via Stratis’ GitHub page, found here. Testing will continue with existing Cirrus Sidechain Masternodes in a lead up to wSTRAX going live on the Ethereum Blockchain, two weeks from now.

Stratis Cold-Staking

Staking is essential to the Proof of Stake consensus mechanism used on the STRAX Blockchain. Blocks are verified and mined by network participants who are willing to set aside a portion of their tokens, effectively freezing them so they cannot be spent. In return, these participants are granted the right to verify transactions and earn bonuses paid in tokens. The larger the number of tokens a participant is willing to stake, the greater the chance they will be selected to mine the next block and earn the associated reward.
While tokens are being staked, they are frozen in a wallet. If the wallet is connected to the blockchain network, it is referred to as a hot wallet. Such an arrangement incurs a level of risk as the wallet is effectively exposed to the internet and therefore susceptible to attack. Conversely, if the wallet stores tokens offline (as is possible in the Stratis wallet, a hardware wallet, or even a paper wallet), it is known as a cold wallet and the staking process is referred to as “Cold Staking”. Cold Staking is inherently safer than staking in a hot wallet since tokens are not susceptible to online attacks while held in an offline wallet.
Cold-Staking has been activated on the STRAX Blockchain since its inception. However, relevant changes have now been made within the STRAX Wallet, enabling Cold-Staking configurations to be set up with relative ease.
This release includes a later release of the STRAX Wallet and an accompanying document that details the steps required to configure Cold-Staking securely while also detailing how to withdraw from your Cold-Staking setup.
