Scheduled

We are upgrading our Tempo Mainnet & Testnet nodes to `v1.6.0`. During the maintenance window, brief interruptions to RPC availability may occur. This release implements the T3 (Wagner) network upgrade, introducing enhanced access key permissions, a signature verification precompile, virtual forwarding addresses, and consensus metadata in block headers. Testnet activates April 21, 2026 at 14:00 UTC and Mainnet on April 27, 2026 at 14:00 UTC.

##RPC Changes:

`tempo_simulateV1` — added New simulation endpoint with TIP-20 token metadata enrichment.

`tempo_forkSchedule` — added New endpoint returning the scheduled fork activation times for the network.

AA transaction validity — modified Transactions with zero `valid_before`, `valid_after`, or zero key expiry are now rejected. Applications submitting AA transactions should ensure these fields are non-zero.

Scoped access key violations — modified Call-scope validation errors now surface at pre-execution rather than transaction validation, changing when scope violations are returned to callers.
