Fireblocks now supports the Songbird blockchain and the SGB token.
Songbird is the Canary Network for Flare. It is designed for testing, development, and community building without affecting the Flare mainnet.
Summary
You only need an SGB wallet if you did not participate in the Flare airdrop on Fireblocks.
If you participated in the Flare airdrop on December 2020 and received tokens on Fireblocks, your airdrop balance will appear under the SongBird (Legacy derivation) wallet in the relevant vault account (the previously registered account). If you have airdrop funds, please move them from your SongBird (Legacy derivation) wallet to a SongBird wallet address in the same or another vault account. This transaction can also be to a one-time address or a whitelisted address in an Internal Wallet. Once the funds have been moved, only use the new SGB wallet.
Why are there two different SGB assets, "SongBird" and "SongBird (Legacy Derivation)"?
In December 2020, Flare offered XRP holders to register their future Flare wallet for a planned airdrop. Fireblocks offered that service and registered future Flare addresses for clients participating in the anticipated airdrop. In order to derive the address we used coin type 544 according to BIP44 derivation scheme. However, the latest recommendation of the Flare organization is to derive addresses using coin type 60 (like most EVM-compatible blockchains on the Fireblocks platform). In order to support both the airdrop and improve future usage, we added the SGB (Legacy derivation) asset. This is only relevant for Fireblocks clients that requested to be registered for the December 2020 airdrop. SGB wallets are now aligned with other EVM-based assets on Fireblocks and according to Flare recommendations.
The SGB (Legacy derivation) wallet should only be used to move the airdrop funds to an SGB wallet as explained above.
