Anti Replay

  • Users can send both signed and unsigned transactions to a Fork. For a signed raw transaction, users may be concerned that the signed transaction could be replayed on the mainnet (instead of on a Fork). To mitigate this threat, the Anti-Replay Protection can be enabled.

  • Specifically, when this option is enabled, the chain ID will be altered to a magic number. Users can input any number within the range of 1-9999, and the Chain ID will ultimately be '999' followed by the input number. In the example, the Chain ID would be '9991' as the final value. This prevents signed transactions from being executed on the mainnet.
