Permissioned Consensus & Institutional Whitelist
Nyxor L1 enforces regulatory access controls at the consensus layer using the Avalanche TxAllowList stateful precompile. Unauthorized transactions are filtered at the node mempool boundary before consuming gas or executing smart contract code.
Transactions from restricted addresses revert automatically at the consensus mempool boundary.

Traditional EVM applications enforce KYC inside Solidity smart contracts (`require(isKyc[msg.sender])`). This has two major security flaws:
Smart contract reverts must still be included in blocks, consuming block space and charging gas to failed transactions.
Non-allowlisted bots can flood the node mempool with spam transactions, crowding out institutional orders during market hours close.
The Subnet-EVM Solution
With Avalanche TxAllowList, the check happens in the Golang consensus client before the transaction ever reaches the EVM.
- Zero Gas Spent: Rejected transactions never hit the blockchain.
- Mempool Gated: Nodes refuse to gossip unapproved signatures.
- Institutional Grade: Satisfies regulatory isolation requirements.
