SUBTENSOR RUNTIME · v483
Subtensor v483 tightens EVM precompile input handling and transaction validation for Proxy and batched calls
Runtime 483 is a small hardening release. It updates how the EVM precompiles handle the input they receive, and how the chain validates transactions made through Proxy and batch (utility) calls. No staking, Emission or network parameters change, and holders do not need to do anything.

Stricter checks for EVM precompile input and Proxy / batched transactions
This release updates how the chain's EVM precompiles (the built-in contracts that let EVM users stake and interact with Bittensor) handle the input they receive. It also updates transaction validation for calls submitted through a Proxy or bundled together in a batch. These changes harden existing behavior. They do not add new features or change any parameters.
