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.

We have an example repository that demonstrates how to construct and sign Tempo transactions: Legacy Ethereum transactions on Tempo can be utilized on Turnkey with viem and ethers.

  • Tempo Mainnet (TBA)
  • Tempo Testnet
