AsterizmDemo contract

Deployment and Configuration of the Basic Protocol Demo Contract

To demonstrate the functionality of our protocol, our team has developed a demo contract that facilitates the transmission of text data between networks. You can find the contract code in our repositories (both the basic and upgradeable versions for EVM and the basic version for TVM networks):

Solana demo program

To complete the full configuration, you need to perform the following steps:

1. Deploy the contracts to the required networks and obtain their addresses. This can be done on both Testnet, and Mainnet

2. Add the obtained addresses to the list of trusted addresses on each network.

3. Send a message containing text from one network to another.

Contract deployment

Here are console commands for simplified deployment

EVM

npx hardhat demo:deploy {initializerAddress} {relayAddress?} {feeTokenAddress?} --network {networkName}

The command accepts the following parameters:

• initializerAddress - mandatory parameter: the address of the initializer on the network. You can review the list of available addresses on the respective pages (Mainnet or Testnet)

• relayAddress - optional parameter: the address of an external relay. You will be able to review the list of available external relays on the respective page

• feeTokenAddress - optional parameter: token address for transfer commission payment

• networkName - mandatory parameter: the name of the network to which the contract is deployed. You can explore the list of available networks here.

Upon successful execution, the command will return a response similar to the following (the address of the demo contract will be displayed under the AsterizmDemo address):

Deployment was done.

Adding Trusted Addresses

To simplify the process of adding trusted addresses, console commands have been developed.

IMPORTANT!

In each network, it is essential to add the trusted address of those networks to which transfers will be sent. That is if you plan to send such transfers:

• Ethereum -> Polygon

• Ethereum -> BSC

• Polygon -> Ethereum

• BSC -> Ethereum

then you should add a total of 4 trusted addresses as follows:

• In the Ethereum network, add 2 trusted addresses (Polygon and BSC)

• In the Polygon network, add 1 trusted address (Ethereum)

• In the BSC network, add 1 trusted address (Ethereum)

EVM

npx hardhat deploy:addTrustedAddress {contractAddress} {trustedChainId} {trustedAddress} --network {networkName}

The command accepts the following parameters:

• contractAddress - mandatory parameter: the address of the demo contract in the current network

• trustedChainId - mandatory parameter: the ID of the network of the trusted address. You can review the list of available networks on the corresponding pages (Mainnet or Testnet)

• trustedAddress - mandatory parameter: the address of the trusted demo contract. You will be able to review the list of available external relays later on a dedicated page. Please note that this parameter accepts a uint value, not address. Therefore, you will need to convert the hexadecimal address to decimal

• networkName - mandatory parameter: the name of the source network. You can check the list of available networks here.

Upon successful execution, the command will return a response similar to the following:
