#### Tax Token deployment (migrated to Uniswap V2)

Tax-token contracts run alongside the V4 deployment as an independent factory. Tokens created here are ERC-20 with optional transfer/trade tax and graduate to Uniswap V2 (instead of V4). See [Tax Token](/fees-rewards/tax-token.md) and [Vaults](/vaults.md) for the user-facing concepts.
