Function call

The getDepositAddress function generates an address based on the provided payload, which must then be funded and submitted on-chain.

const provider = new ethers.BrowserProvider(window.ethereum);
const signer = await provider.getSigner();

const payload: any = {
        userOpHash: "",
        transferType: TransferType.WALLET,
        destinationChainId: "8453",
        destinationTokenAddress: "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
        toAmount: BigInt(Math.floor(0.01 * 10 ** 8),
        destinationRecipient: "0x45c0470ef627a30efe30c06b13d883669b8fd3a8",
        fromTokenAddess: "0xaf88d065e77c8cC2239327C5EDb3A432268e5831",
        fromChainId: "42161",
        fromAddress: "0xeDa8Dec60B6C2055B61939dDA41E9173Bab372b2",
};

const depositData = await aarcCoreSDK.getDepositAddress(payload); 

// make client sign the generated tx
const { to, value, data, gasLimit, chainId, from } = depositData.txData;
const { hash } = await signer.sendTransaction({ to, value, data, gasLimit, chainId, from });

//OPTIONAL: postExecuteToAddress will update the aarc about the tx instanstly
await aarcCoreSDK.postExecuteToAddress({
          depositData,
          hash,
});

Using onramp

// Using moonpay for onramp (you can also use kado)
const payload = {
    // rest of the payload,
    transferType: "onramp"  
}

const provider = "moonpay";

const depositData = await aarcCoreSDK.getDepositAddress(payload);

 const fromToken = {
        chainId: 8453,
        token_address: "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
        amount_required: "35",
        decimals: 6,
      };

const url = await aarcCoreSDK.generateMoonpayOnrampUrl({
        walletAddress: depositData.depositAddress,
        defaultCryptoCurrencyCode: depositData.depositTokenSymbol,
        fiatAmount: fromToken.amount_required,
        fiatCurrencyCode: "USD",
        network: "BASE",
        cryptoTokenData: {
          tokenAmount: fromToken.amount_required,
          tokenCode: depositData.depositTokenSymbol ?? "ETH",
        },
      });

const windowRef = window.open(url, "_blank");
