Address derivation
Turnkey supports Tempo address derivation withADDRESS_TYPE_ETHEREUM.
Transaction construction and signing
During Tempo’s testnet period both transaction types are signable with Turnkey, though policy engine support differs:- Ethereum legacy transactions with full parsing & policy support
- Tempo transactions with only raw payload signing and limited policy support.
Examples
We have an example repository that demonstrates how to construct and sign Tempo transactions:examples/with-tempo: demonstrates transaction construction and broadcast on Tempo.
Tempo Network Support
Turnkey supports:- Tempo Mainnet (TBA)
- Tempo Testnet
Key Features for Tempo
- Out of the box Legacy EVM TX support: Turnkey fully supports the legacy transaction type on Tempo
