What is New?

This major SDK release contains refactored, optimized code and several usage improvements. It requires some changes to the integration code that uses the following SDK methods.

transfer

Use transfer to issue a chain abstracted blockchain transaction. Get the handler to simulate the transfer execution for intent details.

const handler = await ca.transfer({
to: "0x...",
amount: 5,
chainID: 10,
token: "eth",
});

// Execute the transfer
const hash = await handler.exec();

// Simulate the transfer, returns intent data and token info
const response = await handler.simulate();

await ca.transfer().to("0x...").amount(5).chain(10).token("eth").exec()

bridge

Use bridge to issue a chain abstracted blockchain transaction. Get the handler to simulate the bridge execution for intent details.

const handler = await ca.bridge({
token: "usdt",
amount: 10,
chainID: 137,
});

// Execute the bridge
await handler.exec();

// Simulate the bridge, returns intent data and token info
const response = await handler.simulate();

await ca.bridge().token("usdt").amount(10).chain(137).exec();

getEVMProviderWithCA

The new getEVMProviderWithCA method retrieves the chain abstraction enabled EIP-1193 provider. Use this provider to issue request] with eth_sendTransaction for chain abstracted transactions.

let provider = window.ethereum;

const ca = new CA();
ca.setEVMProvider(provider);
const providerWithCA = ca.getEVMProviderWithCA();  // Get EIP-1193 provider first

request

Get a chain abstraction enabled EIP-1193 provider with getEVMProviderWithCA. Use this provider to issue chain abstracted request with eth_sendTransaction. 

let provider = window.ethereum;

const ca = new CA();
ca.setEVMProvider(provider);
const providerWithCA = ca.getEVMProviderWithCA();  // Get EIP-1193 provider first

await providerWithCA.request({   // Then use EIP-1193 provider to issue request
    method: "eth_sendTransaction",
    params: [{
        to: "0xEa46Fb4b4Dc7755BA29D09Ef2a57C67bab383A2f", 
        from: "0x7f521A827Ce5e93f0C6D773525c0282a21466f8d",
        value: "0x001"
    }],
})

let provider = window.ethereum;

const ca = new CA();
ca.setEVMProvider(provider);

await ca.request({  //This has changed, there is no request method implemented for CA class
    method: "eth_sendTransaction",
    params: [{
        to: "0xEa46Fb4b4Dc7755BA29D09Ef2a57C67bab383A2f", 
        from: "0x7f521A827Ce5e93f0C6D773525c0282a21466f8d",
        value: "0x001"
    }],
})
