# Stellar MAINTAINER = Tomas Susanka AUTHOR = Tomas Susanka REVIEWER = Jan Pochyla 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](https://www.stellar.org/developers/). ## Transactions Stellar transaction is composed of one or more operations. We support all [operations](https://www.stellar.org/developers/guides/concepts/list-of-operations.html) except the Inflation operation (see [here](https://github.com/trezor/trezor-core/issues/202#issuecomment-392729595) 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.
