Token locking on Robinhood Chain: FAQ.

14 questions about locking, vesting and burning tokens on Robinhood Chain, each answered in its first sentence. Questions about wallets, referrals and support are in the HoodLock FAQ.

The chain#

What is Robinhood Chain's chain ID?#

Robinhood Chain mainnet is chain ID 4663. It is an Ethereum L2 built on the Arbitrum stack, ETH is the gas token, the public RPC is https://rpc.mainnet.chain.robinhood.com and the explorer is robinhoodchain.blockscout.com. Every parameter is on the network page.

Locks#

Does Robinhood Chain have a token locker?#

Yes. HoodLock is a non-custodial token locker built for Robinhood Chain: it locks any ERC-20, including v2-style LP tokens, until a date you choose, for a flat 0.005 ETH per lock, and gives every lock a public proof page. The token locker page covers what it guarantees.

Can a lock be shortened?#

No. The locker only accepts a new unlock time that is later than the current one, so a date can be extended for free as often as you like but never pulled in, and no admin function can override that. See extending a lock.

What happens when a lock expires?#

Nothing happens automatically: the tokens stay in the contract until the lock owner sends a withdrawal, which costs gas only and can wait as long as the owner likes. When a lock expires covers what holders see at that point.

Liquidity#

Does Robinhood Chain have a liquidity locker?#

Yes. HoodLock locks liquidity on Robinhood Chain two ways: v2-style LP tokens go in the token locker like any ERC-20, and Uniswap V3 and V4 positions go in the HoodLock Liquidity Locker at 0x91Aa2dA1956C77F8448E18DCaf53383bCc658e67. The LP locker for Robinhood Chain explains both.

Can I lock Uniswap V4 positions?#

Yes. The HoodLock Liquidity Locker accepts Uniswap V4 positions on Robinhood Chain, including pools with launchpad hooks; if a hook could act on liquidity removal and is not on the reviewed list, the app warns you before you lock. See the Uniswap V4 liquidity lock, and the Uniswap V3 liquidity lock for V3.

Do I keep collecting fees on a locked position?#

Yes. A locked Uniswap V3 or V4 position keeps earning trading fees and the owner collects them whenever they like, while the liquidity itself stays locked; HoodLock keeps 25% of what is collected, fixed per lock when it is created. The liquidity locker docs explain the fee flow.

Vesting#

Is there token vesting on Robinhood Chain?#

Yes. HoodLock vests ERC-20 tokens on Robinhood Chain with a linear release and an optional cliff, up to 200 beneficiaries in one transaction, for 0.005 ETH per schedule. See token vesting on Robinhood Chain.

Can a vesting schedule be cancelled?#

No HoodLock function can cancel or edit a schedule once it exists: no revoke, no sweep, no rescue. The token is the exception, because an upgradeable, pausable or blacklisting token can still freeze a schedule. The vesting contract rules list every limit.

Burns#

What is the burn address on Robinhood Chain?#

The burn address on Robinhood Chain is the standard EVM dead address, 0x000000000000000000000000000000000000dEaD, which has no private key, so tokens sent there never move again. Sending to it does not lower totalSupply; HoodLock's burner sends tokens there in one transaction and records a proof page. See how to burn tokens on Robinhood Chain.

Verification#

How do I check if a token's liquidity is locked?#

Paste the token or pool address into the free liquidity lock checker, which lists every Uniswap V3 and V4 position HoodLock holds for it with the value and unlock date, no wallet needed. For v2 LP and team tokens use the token lock checker, and how to check if liquidity is locked adds DexScreener and the explorer.

Costs and safety#

What does a lock cost?#

A token lock, a burn or a vesting schedule costs a flat 0.005 ETH on HoodLock, and a Uniswap V3 or V4 position lock costs 0 ETH upfront plus 25% of the trading fees collected while it is locked. Withdrawing, extending and claiming cost gas only. Full detail on the fees page.

Is HoodLock audited?#

Yes. SBSecurity reviewed the token locker and vesting contracts in September 2026 (zero findings) and the Liquidity Locker in October 2026 (six findings, none high, all fixed and verified before launch). Neither review covers the burner, the airdrop contract or anything off chain. Both reports are on the audit page.

Does HoodLock launch tokens?#

No. HoodLock is a locker, not a launchpad: it integrates with Robinhood Chain launchpads such as FOBO, Pons, Doppler and Fendex, and locks, vests or burns the tokens and positions a launch leaves with the creator. The token locker page lists what can be locked.
