const chainId = SupportedChainIds.ZKSYNC;
const value = "1000"; // 1000 paraUSD in ether units
 
const approveCalldata = approveParabolUSDCalldata(chainId, value);
console.log("Approve paraUSD calldata:", approveCalldata);

Notes

• The generated calldata can be used in a transaction to approve paraUSD spending for another contract or address.
• This approval is necessary before lending paraUSD.
• The value should be provided in ether units (1 paraUSD = 1e18 ether).
• The method will throw a ParabolSDKError if the value is zero, the chain ID is not supported, or if there’s an error generating the calldata.
