# XDR decoding tool available at:
#   https://www.stellar.org/laboratory/#xdr-viewer
#
# ## Test Info
#
# The default mnemonic generates the following Stellar keypair at path 44'/148'/0':
#   GAK5MSF74TJW6GLM7NLTL76YZJKM2S4CGP3UH4REJHPHZ4YBZW2GSBPW
#   SDE2YU4V2IYSJIUH7MONDYZTSSLDXV5QDEGUUOLCU4TK7CZWTAXZ5CEG
#
# ### Testing a new Operation
#
# 1. Start at the Stellar transaction builder: https://www.stellar.org/laboratory/#txbuilder?network=test
#   (Verify that the "test" network is active in the upper right)
#
# 2. Fill out the fields at the top as follows:
#   Source account: GAK5MSF74TJW6GLM7NLTL76YZJKM2S4CGP3UH4REJHPHZ4YBZW2GSBPW
#   Transaction sequence number: 4294967296 (see _create_msg)
#   Base fee: 100
#   Memo: None
#   Time Bounds: <leave blank>
#
# 3. Select the operation to test, such as Create Account
#
# 4. Fill out the fields for the operation
#
# 5. Scroll down to the bottom of the page and click "Sign in Transaction Signer"
#
# 6. In the first "Add Signer" text box enter the secret key: SDE2YU4V2IYSJIUH7MONDYZTSSLDXV5QDEGUUOLCU4TK7CZWTAXZ5CEG
#
# 7. Scroll down to the signed XDR blob and click "View in XDR Viewer"
#
# 8. Scroll down to the bottom and look at the "signatures" section. The Trezor should generate the same signature
