# Solana definitions
|
|
|
|
To allow nicer token presentation on the device, Trezor allows passing a token
|
|
definition as part of the additional info. Currently only one token can be included in
|
|
the definitions. Solana tokens are uniquely identified by their mint account. Trezor
|
|
additionally expects a name and a ticker symbol.
|
|
|
|
In the future we might also include definitions for instructions.
|
|
|
|
## Retrieving the definitions
|
|
A full list of Solana definitions is compiled from multiple sources and is available [in
|
|
a separate repository](TODO).
|
|
|
|
From this list, a collection of binary blobs is generated, signed, and made available
|
|
online.
|
|
|
|
A given Trezor firmware will only accept signed definitions newer than a certain date,
|
|
typically one month before firmware release. This means that a client application should
|
|
either always fetch fresh definitions from the official URLs, or refresh its local copy
|
|
frequently.
|
|
|
|
The base URL for the definitions is `https://data.trezor.io/firmware/solana-definitions/`.
|
|
|
|
## Definition format
|
|
|
|
Look at [`ethereum-definitions.md`'s](ethereum_definitions.md) `Definition Format` section.
