Manage Your Arc Token After Launch: Taxes, Limits and Ownership

Read and change an Arc token after launch: taxes, exemptions, wallet limits, minting, trading state and ownership handover, with the risks of each one.

The short version

7 steps, roughly 12 minutes of clicking. The full walkthrough is below.

  1. 11. Read the live configuration firstPaste the token address and let the tool decode supply, tax rates, fee recipients, wallet limits, trading state and the current owner straight from Arc Mainnet. Change nothing until you have read everything.
  2. 22. Set the tax rates and fee recipientsAdjust buy, sell and transfer taxes within the ceilings you committed to at launch, and choose how each tax share is split between marketing, development, liquidity and burn.
  3. 33. Adjust the transaction and wallet limitsRaise or remove the maximum transaction and maximum wallet percentages once trading is stable. Check the pool is exempt before tightening anything.
  4. 44. Add the exemptions your pool needsExempt the Uniswap pair, the router and any locker or treasury contract from tax and limits. Missing exemptions are the most common cause of trades that revert or under-deliver.
  5. 55. Open, pause or schedule tradingEnable trading when liquidity exists and set the block delay that keeps bots out of the first blocks. Pausing trading is visible to buyers, so use it deliberately.
  6. 66. Mint or burn supply deliberatelyIf the token is mintable you can mint up to the cap, and you can burn treasury supply at any time. Minting dilutes holders, so announce it before you do it, never after.
  7. 77. Hand over ownership or renounce itTransfer the owner role to a multisig or timelock, or revoke it permanently once every setting is final. The tool lists exactly which capabilities disappear before you sign.
Diagram comparing the two ways the flat 50 USDC fee is collected. On the left, seven tools charge the fee inside the same call that does the work and forward it to an immutable treasury with no setTreasury function. On the right, Token Manager, Revoke Ownership and Burn call onlyOwner functions on the user's own token, so the wallet pays ArcToolsPayment.unlock per token instead and the receipt is read back by ServiceGate.
The split is forced by the EVM rather than chosen: onlyOwner compares msg.sender to the token's owner, so no wrapper contract can pay on your behalf. A second payment for the same token is rejected on purpose.

A launched token is rarely finished. The first week of trading answers questions the launch form could not: is the tax scaring off buyers, is the max wallet limit blocking real purchases, is the pair exemption in place? Those are settings, and settings can change — as long as the contract still has an owner.

The Arc Token Manager reads an Arctools-deployed token directly from Arc Mainnet, shows you its live configuration, and lets you change any parameter the contract still permits. This guide covers each family of settings, what changing it does to holders, and the order of operations that keeps you from locking yourself out of a fix you will need later.

Before you start

  • The token address and the owner wallet. The manager controls tokens deployed through Arc Token Launch or Arc Bundle Launch where you still hold the owner role. Tokens deployed elsewhere expose different admin interfaces, and the tool will tell you what it can and cannot read rather than pretending otherwise.
  • USDC on Arc Mainnet. Chain id 5042, RPC https://rpc.mainnet.arc.io, explorer https://explorer.arc.io. The management session is a flat 50 USDC, and every change you approve afterwards costs Arc gas in USDC — cents per transaction.
  • A list of intended changes. Decide them before you start. A management session is one fee, so batching your changes into a single sitting is both cheaper and easier to explain publicly than a week of unexplained one-off transactions.
  • Willingness to disclose. Every change you make here is public and permanent in the transaction history. Holders will see it, so say it first.

1. Read the live configuration first

Paste the token address. The tool decodes the contract state: total supply, current buy, sell and transfer tax rates, the fee recipient addresses and their shares, maximum transaction and wallet percentages, the trading state, and the owner.

Read all of it before changing anything, and compare it against two sources:

  • Your launch notes, to spot settings that differ from what you intended — a tax ceiling set higher than you remember is far easier to fix on day one than on day thirty.
  • The Arc Token Checker, which reports the same state the way a cautious buyer sees it. Anything the checker flags as a risk is a candidate for this session.

2. Set the tax rates and fee recipients

Taxes can move within the ceilings you committed to at launch. That ceiling is the important number: buyers were told "the sell tax can never exceed 10%", and the contract is what makes that statement true or false.

Guidance that applies to every adjustment:

  • Move in small steps, and announce them. A sell tax moving from 3% to 4% is a treasury decision. One jumping from 3% to the ceiling right after a price drop is a rug pattern, regardless of intent.
  • Set transfer tax to zero if it is not already. Wallet-to-wallet taxation makes the token awkward in every other contract it touches and buys you almost nothing.
  • Point tax revenue at visible destinations. Shares going to known marketing, development, liquidity and burn addresses are defensible; a single destination wallet is the configuration that gets analysed first.
  • Send a share to liquidity and it stays in the pool. A liquidity share is recycled depth rather than income, which matters when you explain where the money went.
  • Model the total. Buy tax, sell tax and burn-on-transfer stack. If a round trip costs a buyer 20%, they will not make a second one.

3. Adjust the transaction and wallet limits

Limits exist to stop one wallet buying an outsized share of the pool in the first seconds. Once trading stabilises, they are usually doing more harm than good.

  • Raise the maximum transaction if buyers report failed purchases. Reverted buys from a low cap look like a broken token.
  • Raise or remove the maximum wallet as distribution broadens. A strict cap prevents large holders, which is either the point or an obstacle depending on the token you want.
  • Check the pool before tightening. The pair must be exempt. If the max wallet is smaller than the pool's share of supply, the pool cannot hold its own tokens and trades revert.
  • Keep exemptions in step with your infrastructure. Any contract that holds or moves your token — the pair, the router, a locker, a treasury, a staking contract, the multisender — needs exemption from tax and limits to operate freely. Batch these into the same session as the tax changes so your community sees one coherent set of edits.

4. Add the exemptions your pool needs

Exemptions are the least glamorous and highest-impact settings in the contract. A missing pair exemption means the router's own transfers pay tax, shrinking what arrives at the pool and pushing small trades below their minimums; a missing treasury or staking exemption means every internal transfer leaks tax.

Standard set for a launched token:

  1. The Uniswap pair that trades your token.
  2. The router the pool is traded through.
  3. The locker, if LP or tokens are held by the Arctools Liquidity Locker.
  4. Operational contracts — a multisender during a distribution, a treasury, a vesting contract.

Do this before you renounce anything. Exemptions cannot be added afterwards, and a token whose pair is taxed has no fix once the owner role is gone.

5. Open, pause or schedule trading

Trading state is binary: until it is open, transfers revert. Sequence it against your pool, or your first buyers hit failed transfers and tell everyone the token is broken.

Two features sit alongside the switch:

  • The trading pause. Genuinely useful when something goes wrong — an exploit, a mispriced pool, a stuck contract — and genuinely scary to buyers, because a token that can be paused can also be paused maliciously. Disclose it, and use it only with an explanation attached.
  • The anti-sniper block delay. It holds the first buys back for a number of blocks, which on Arc means a short wall-clock window. It discourages lazy bots and stops nobody determined; the structural fix is a bundle launch, where pool and first buys land in one atomic transaction.

6. Mint or burn supply deliberately

If your token is mintable, the manager can mint up to the cap. This is the single most trust-destroying action available in the tool, and the reason is arithmetic rather than sentiment: new supply either dilutes holders or is sold into the pool, and both are visible.

Rules that keep a mint defensible:

  • Announce before, never after. A mint disclosed in advance is a treasury operation. A mint discovered on the explorer is a betrayal.
  • Mint to a stated destination with a stated purpose — liquidity expansion, a grant programme, a buyback war chest.
  • Expect a price response. The market reprices dilution immediately, and usually prices the risk of more dilution higher still.

Burning is the mirror image. The token burn tool calls the contract's burn function, so the supply figure on the explorer genuinely falls rather than tokens being parked at a dead address. It is frequently the correct use of unsold allocation.

You can also adjust the automatic burn applied to transfers. Raising it makes supply deflationary over time; it also means recipients receive less than the amount you quote them in public, so keep the number small enough that your communications stay simple.

7. Hand over ownership or renounce it

Ownership is the switch that controls everything above. Two credible destinations:

  • A multisig or timelock. Ownership moves to an address needing multiple signatures or a delay before it can act. You keep the ability to fix things, and buyers can see that no single key controls the contract — standard practice before a launch with real capital at stake.
  • A renounce. The owner becomes the zero address and every administrative function is permanently uncallable: no tax changes, no limit changes, no minting, no new exemptions. Supply and existing rates freeze exactly where they are.

Before renouncing, confirm all four of these: taxes final, limits final, exemptions complete, trading open. The Revoke Ownership tool prints a plain-language list of the capabilities you are giving up before you sign, and make your Arc token safe puts the renounce in its proper position in the launch sequence.

One-sided risk worth stating plainly: if the owner key is lost before you renounce, the admin functions are gone just as surely, but without the trust benefit. Move ownership to something you will still control in a year.

What it costs

Item Amount Notes
Management session 50 USDC flat Covers the session, however many changes you make in it
Each onchain change Gas only Cents per transaction at the 20 Gwei floor
Mint Gas only No fee, and no cost basis: you are creating supply
Burn Gas only Irreversible, verifiable on the explorer

Gas arithmetic: 20 Gwei means 100,000 gas costs 0.002 USDC and a million gas costs 0.02 USDC. A tax change, an exemption or a limit update each consumes well under a million gas, so a session with eight changes costs single-digit cents.

Common mistakes

  • Raising taxes without warning. The most common way teams destroy trust they spent months building.
  • Changing taxes to the ceiling. Your committed ceiling is a maximum, not a target. Headroom nobody uses is what makes the ceiling credible.
  • Renouncing before exemptions are set. Unfixable, and the pair pays tax forever.
  • Leaving limits tighter than the pool. The pool cannot hold its own tokens and every trade fails.
  • Minting without announcing. The explorers and the checker report supply. Assume discovery.
  • Forgetting which wallet owns the token. Only the current owner can move ownership, so if that key sits in a browser wallet nobody has opened in months, find it first.
  • Treating the pause switch as a feature to keep forever. Buyers price a pause capability as a risk. Remove or disclose it.
  • Running many single-change sessions. Each is a transaction and a story. Batch them.

Where to go next

When the configuration is final, the next step is closing the doors you no longer need: Revoke Ownership removes the admin role permanently, and burning the unallocated supply shrinks supply in a way anyone can verify.
