SpendBundle Demo App

This demo application generates an address for a puzzle which;

• Sends TXCH to an address
• Requires a signatures to be spent
• Makes a coin announcement

Upon funding this address the application will create a spend bundle which spends a coin of this address and sends that spend bundle to the SpendBundle.com API.

The SpendBundle.com API returns a modified spend bundle with fees attached.

Requirements

• SpendBundle.com account
• testnet11 TXCH to find the address

Notes

Your account likely has a limit of only 1 concurrent spend at a time. The application handles this situation but will need to wait for on-chain actions to occur before being able to create additional spend bundles.
