Transaction Construction

To construct EVM transactions using the provided code, you can follow the examples below. Make sure to replace placeholders with your actual addresses, amounts, and other relevant information.

Gradle Dependencies:

gradleCopy codedependencies {
    //...
    implementation "network.particle:api-service:{latest-version}"
}

Find the latest version of the SDK here.

Example Code:

ERC20 Transfer (Native):

kotlinCopy codeval amount = "0x38d7ea4c68000" // Hexadecimal string
val serializeTransaction = ParticleNetwork.evm.createTransaction(from, to, amount).serialize()

ERC20 Transfer (Token):

kotlinCopy codeval amount = "1000000000000000" // Decimal string
val contractParams = ContractParams.erc20Transfer(tokenContractAddress, to, amount)
val serializeTransaction = ParticleNetwork.evm.createTransaction(from, tokenContractAddress, contractParams).serialize()

ERC721 SafeTransferFrom:

kotlinCopy codeval tokenContractAddress = "0x76Afcd13B9B7D93Fb3fb8D42dDF68bEe4CEF9765"
val contractParams = ContractParams.erc721SafeTransferFrom(tokenContractAddress, from, to, tokenId)
val serializeTransaction = ParticleNetwork.evm.createTransaction(from, tokenContractAddress, contractParams).serialize()

ERC1155 SafeTransferFrom:

kotlinCopy codeval tokenContractAddress = "0xA07e45A987F19E25176c877d98388878622623FA"
val amount = "1" // Decimal string
val id = "123"
val contractParams = ContractParams.erc1155SafeTransferFrom(
    tokenContractAddress,
    from,
    to,
    id,
    amount,
    data = "0x"
)
val serializeTransaction = ParticleNetwork.evm.createTransaction(from, tokenContractAddress, contractParams).serialize()

Write Contract:

kotlinCopy codeval params = ContractParams.customAbiEncodeFunctionCall(
    contractAddress = "0xd000f000aa1f8accbd5815056ea32a54777b2fc4",
    methodName = "mint",
    params = listOf("1"),
    abiJsonString = ""
)
val serializeTransaction = ParticleNetwork.evm.writeContract(address, params).serialize()

The above code needs to handle exceptions
