Error Handling

The Smart Contract Scanner component provides comprehensive error handling through the onError callback and the ContractError enum.

NETWORK_ERROR: Connection issues with the blockchain provider
SCAN_FAILED: General scanning failure
RATE_LIMIT: API rate limit exceeded
TIMEOUT: Request timeout
UNKNOWN: Unspecified error

Example Error Handler

// Example error handler with different responses per error type
const handleContractError = (error: ContractError) => {
  switch(error) {
    case ContractError.INVALID_ADDRESS:
      showNotification("Please enter a valid Ethereum address");
      break;
    case ContractError.NOT_FOUND:
      showNotification("Contract not found on this network");
      break;
    case ContractError.NOT_VERIFIED:
      showNotification("This contract is not verified", "warning");
      break;
    case ContractError.NETWORK_ERROR:
      showNotification("Network connection error. Please try again", "error");
      break;
    case ContractError.RATE_LIMIT:
      showNotification("Too many requests. Please wait and try again", "error");
