Base Token Manager: Update a Tokenry ERC-20 After Deploy

Tax rates, LP pairs and other owner settings of a Tokenry ERC-20 on Base stay editable in the Base token manager until ownership is renounced. Only the deploying wallet opens them, while it is still the owner. Each change is one transaction; the wallet pays Base gas in ETH, and Tokenry charges nothing on top.

Why Tokenry

  • No Code Required

    Create and launch tokens without writing any code. Visual configuration for all features.

  • Fully Transparent

    All token data is publicly visible and verifiable on block explorers.

  • Multi-Chain

    Works on Solana and 8 EVM chains, including Ethereum, Base, Arbitrum, Polygon and BNB Chain.

  • Full Ownership

    You have full control. We never hold your keys, tokens, or authority.

How it works

Tax and LP pair changes on Base, step by step

  1. 1

    Load your Base tokens from the deploying wallet

    Connect the wallet that deployed the token and switch it to Base mainnet. Its Tokenry tokens appear as cards.

  2. 2

    Open the Tax Settings, Swap Settings or LP Pools tab

    Tabs follow the features set at deploy. A tax token gets these three plus Rescue; Ownership is always there.

  3. 3

    Type the rate, pair address or threshold

    Update tax rates, Mark as LP and the other section buttons each send one transaction to your token contract, with no token approval first.

  4. 4

    Confirm the wallet prompt and open BaseScan

    The wallet opens as soon as you press the button. Tokenry shows no review screen first, so check the value you typed. A confirmed change shows a BaseScan link.

Frequently Asked Questions

Does Tokenry charge for Token Manager changes on Base?

Tokenry charges nothing for them, so each transaction costs only Base gas in ETH, including the L1 fee for posting its data to Ethereum. Tax rates and the tax split have separate buttons, so changing both is two transactions, each with its own gas. A transaction that reverts still pays its gas and leaves the token as it was.

How do I lower the sell tax on my Base token after trading starts?

Open Tax Settings, enter the new buy, sell and transfer rates, and press Update tax rates. Each rate can be 0% to 20%. Use whole numbers, because some decimal rates such as 1.1% fail before the wallet opens. Every trade after the transaction confirms pays the new rates; the contract address, holders and pools do not change. After ownership is renounced, the rates stay fixed.

When does my Base token process the tax it holds?

During a taxed sale into a marked pair, once the token contract holds at least the swap threshold and Auto-process fees is on. Each run processes the threshold amount. Nothing is processed while the WETH pair the contract swaps through, the deploy pair unless the router changed, holds none of the token. That also applies to Process fees now, which runs processing by hand for an amount you choose.

The details

More about the Base Token Manager

01

Uniswap pairs in the LP Pools tab on Base

On a Base tax token, only pairs marked as LP pairs charge the buy and sell rates. A trade through an unmarked pair pays the transfer rate instead, which may be 0%. The token/WETH pair on Uniswap v2 that the deploy created through the default router is marked from the start.

With the default router, a first Uniswap v2 ETH pool from the Base liquidity pool creator goes into that same pair. To tax trades through any other Uniswap v2 pair, such as a USDC pair, paste its pair address in LP Pools and press Mark as LP; Unmark removes it. Do not mark a v3 or v4 pool: Uniswap's routers there do not support taxed tokens, so taxed sells can fail. Marking needs the owner, so mark each pair before you renounce.

A marked pair can hold any amount of the token, whatever the holding limit. Saving a new holding limit in the Anti-Whale tab fails for tokens with decimals, so use that tab to exempt addresses from the limit.

02

Swap Settings for a Base token's collected tax

A Base tax token holds the liquidity and marketing parts of its tax until processing runs. Processing then swaps half of the liquidity part for ETH and adds both halves to the token/WETH pair. The LP tokens go to the Liquidity owner set in Swap Settings. The marketing part is swapped for ETH as well, unless Fees-in-Token pays it in the token.

The swap threshold starts at 0.05% of supply, and the contract rejects any value above 1%. With Auto-process fees off, collected tax stays in the contract until processing runs. DEX router changes the router used for these swaps, and the new router's WETH pair is marked as an LP pair at once.

Tax tokens made with Tokenry on other EVM chains have the same Swap Settings tab, reached from the token manager hub.

03

Tax distribution and marketing wallets

Each taxed trade splits its tax by the distribution in Tax Settings. The three shares must total 100%; use whole numbers, since many decimal shares fail. The burn share is burned in the same transfer, so the total supply drops at once. The marketing part goes to as many as 10 marketing wallets, split by the share set for each.

The starting split, wallets and fee currency come from the Base token creator form.
