Stellar

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 Offer
  • Manage Data
  • Manage Offer
  • Path Payment
  • 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.
