ADVISORS = ZuluCrypto

This implementation of Stellar for Trezor Core is mostly based on the trezor-mcu C implementation by ZuluCrypto.

Stellar has a comprehensive developers documentation.

Transactions

Stellar transaction is composed of one or more operations. We support all operations except the Inflation operation (see here for rationale). A list of supported operations:

Account Merge
Allow Trust
Bump Sequence
Change Trust
Create Account
Create Passive Sell Offer
Manage Data
Manage Buy Offer
Manage Sell Offer
Path Payment Strict Receive
Path Payment Strict Send
Payment
Set Options

Since a simple transaction can be composed of several operations, first the StellarSignTx message is sent to Trezor, which includes the total number of operations. Then the different operations are consecutively send to Trezor.
