Debug

Known issues

breakingIn 0.9, the API was completely rewritten. Old imports from pycoin.key.PrivateKey or pycoin.key.PublicPair no longer work. Use Key class instead.

fix

Replace `from pycoin.key import PrivateKey` with `from pycoin.key import Key`.

affects: <0.9

gotchaWhen creating transactions, ensure you use Spendable objects correctly. Missing scripts or incorrect txouts can cause 'unspent not found' errors.

fix

Always provide correct scriptPubKey hex and amount for each Spendable.

affects: all

gotchaThe library defaults to Bitcoin mainnet. If you need testnet, explicitly set network='XTN' (for Bitcoin testnet) or use the Network object.

fix

Use `network = Network('XTN')` for Bitcoin testnet.

affects: all

deprecatedThe old command-line tool `ku` is deprecated in favor of `pycoin-ku`. Scripts relying on the `ku` command may break.

fix

Replace `ku` with `pycoin-ku` in shell scripts.

affects: >=0.9
