Team Token Locks on Arc: The Complete Guide

A team token lock puts an allocation into a contract that will not release it before a date you commit to publicly. It answers the oldest question in token launches — what stops the founders selling first — with a contract rather than a paragraph.

Works on Arc testnet today; mainnet September 16, 2026.

Token lock versus liquidity lock versus vesting

Three different things, routinely conflated:

• A liquidity lock immobilises LP tokens so the trading pool cannot be withdrawn. Covered here.
• A token lock immobilises a plain token allocation — team, treasury, advisors, reserves — until a single unlock date.
• Vesting releases an allocation gradually over time, usually after a cliff. Covered here.

A lock is a cliff with no curve after it. Use a lock when the allocation should be untouchable for a defined period and then fully available; use vesting when release should be progressive. Most credible cap tables use both: reserves under locks, contributor allocations under vesting.

What should be locked

Team and founder allocations. The obvious one, and the one buyers look for first.

Advisor allocations. Often smaller, often forgotten, often the first supply to hit the market.

Treasury and reserves. Locking these with staged expiries tells the market when new supply can appear, which is more valuable than a promise that it will not.

Marketing and partnership pools. If these are unlocked and unlabelled, they are indistinguishable from a team wallet to anyone reading the holders tab.

The general principle: any wallet holding a material share of supply should be either a lock, a vesting contract, a pool, or explained. Anonymous concentration is the thing that makes experienced buyers leave.

How to lock team tokens on Arc

Team Finance's token lock tool is non-custodial and has been running since 2020, with more than $2.7 billion secured across 40,000+ projects on 26 chains.

1. Connect to Arc and fund the wallet with USDC. Gas on Arc is USDC and testnet transactions average about $0.004, so lock fees are negligible. Network setup.
2. Open the token lock tool and select Arc.
3. Enter the token contract address and the amount to lock.
4. Set the unlock date — and set it against your roadmap, not against a round number.
5. Optionally set the withdrawer address. This is who can claim at unlock; it does not have to be the depositing wallet, which is useful for treasuries with separate operational and custody wallets.
6. Approve, then lock. Two transactions.
7. Publish the lock link alongside the token contract and any liquidity lock.

Structuring locks that are actually believed

Ladder the expiries. One lock releasing everything on a single day creates a cliff event the market will price in weeks ahead. Several locks releasing in tranches spreads that out and reads as planning rather than a countdown.

Match locks to milestones. A lock expiring the quarter after a scheduled mainnet deliverable tells a coherent story. A lock expiring six weeks after launch does not.

Lock more than the minimum. The credibility gain is not linear in duration, but it is real, and the marginal cost on Arc is fractions of a cent.

Say what happens at unlock, before it happens. Silence into an unlock date is the worst version of this. Announce an extension, a re-lock, or an intended use, at least a month out.

Verifying a lock

Anyone can check, and you should check your own. Open the token contract on the explorer, go to the holders tab, and confirm the locked balance sits in the locker contract rather than a personal wallet. Then read the unlock timestamp and the amount from the locker itself. How to read Arcscan and the full verification walkthrough.

The number to sanity-check is the share: a lock covering 3% of supply while 40% sits loose in an anonymous wallet is a lock in name only.

Timing on Arc

Public mainnet opens September 16, 2026 and Circle has not published mainnet chain ID, RPC or explorer host. Until then, run locks on the public testnet — chain ID 5042002, faucet at faucet.circle.com — to confirm your amounts, dates and withdrawer addresses are right before real supply is involved.
