How Phanterium works

Introduction

Phanterium is the schedule layer after a token exists. Launchpads mint supply. Phanterium decides when that supply can move. Deposit an ERC-20 into an immutable vault, publish a proof URL, and let the beneficiary claim when the clock allows nobody else can.

Built for the minutes after a pad create (dev buys, leftovers) and for slower team or investor vesting. It is not a launchpad, DEX, chart, or LP locker.

On Robinhood Chain, gas and lock fees are ETH. Confirmations finalize quickly, so the preview you sign is the position that appears.

Concepts

Every Phanterium position is an on-chain record: token, beneficiary, creator, credited amount, claimed amount, start, cliff, and end. Tokens leave the creator wallet at creation. They sit in the vault until claim.

A hard lock is a vest whose cliff equals its end. The same contract stores both. Each position still gets its own proof page.

Contracts

These are the canonical deployments on Robinhood Chain. Match the address in your wallet before you approve a token spend.

Connect a wallet

1. Open Launch app.
2. Connect MetaMask, Rabby, or another injected browser wallet.
3. Switch the wallet to Robinhood Chain if it is not already there.
4. Hold ETH for gas and for the lock fee (0.0019 ETH ≈ $5 flat, or 0.0034 ETH ≈ $9 for a split).

After connect, the app opens the dashboard: overview, locks, vesting, streams, airdrops, escrow, and staking. You do not create an account. The wallet is the identity.

If the wallet is on the wrong network, the auth screen asks you to switch to Robinhood Chain before it opens the console.

Create a hard lock

A hard lock seals an ERC-20 amount until a fixed unlock time. Nothing releases early. When that time is reached, only the beneficiary can claim what remains.

1. Go to Locks.
2. Pick a token from the connected wallet. The list is the set of ERC-20 balances that wallet holds on Robinhood Chain.
3. Set the amount. Percent chips and the slider use your full token balance when you press MAX. Keep enough ETH aside for the lock fee and gas.
4. Set duration with days, hours, and minutes, or with the calendar. Those controls stay in sync. Unlock time is stored and displayed in UTC.
5. Choose who receives the unlock: yourself, another wallet, or a split across several addresses.
6. Read the preview. Type, unlock time, duration, destination, amount, and fee must match the wallet prompt.
7. Approve the token if the vault does not already have allowance, then sign the lock.

After the transaction confirms, the schedule cannot be cancelled, shortened, or redirected. Not by you. Not by an admin key. The vault does not store a draft. The signed payload is the schedule that exists on-chain.

If the token charges a transfer fee, the position is credited with what actually arrived in the vault, never more than that. A lock that would already be fully unlocked at confirm is rejected. A start time in the past is also rejected, so a backdated vest cannot look locked on a proof page while most of the bag is already claimable.

Beneficiaries and splits

The beneficiary is the only address that can claim. It is set at creation and cannot be changed. Default is the connected wallet.

A split creates one position per destination, each with its own proof URL. The create costs a flat 0.0034 ETH (~$9) in one transaction. If the creator was referred, 15% of that 0.0034 ETH goes to the referral pool. Amounts are allocated by the percentages you enter. The last row receives the remainder so units are not lost to rounding.

Linear vesting

Vesting is for allocations that should unlock over time rather than on a single date. Create it from Vesting.

• Start. The clock for the linear portion. If omitted, the contract uses the block timestamp at creation.
• Cliff. Nothing is claimable before this timestamp, even if the linear formula would already have released some amount.
• End. At this timestamp the full credited amount is released.

After the cliff, released amount grows every second from start to end:

released = amount × (now − start) / (end − start), then clamped so that nothing is released before the cliff and everything is released at end.

The beneficiary can claim as often as they want. Each claim pays only what has accrued since the last claim. Restaking, streaming, or other modules do not rewrite this schedule.

Proof pages

Every position publishes at /lock/{id}. The page reads live contract state: amount, token, beneficiary, creator, countdown, claimed, claimable, and whether the schedule is a hard lock or a vest.

Holders do not connect a wallet to read it. Paste the URL next to the token contract. The rule is simple: if it is not on this page, it is not locked.

The beneficiary can claim from the same page once the clock allows. Copy proof link copies the canonical URL for that id.

Share cards

When someone posts a proof URL on X, Discord, or Telegram, the unfurl card is generated from the same on-chain fields: amount, ticker, lock type, duration, unlock time, share of total supply, and beneficiary. It is not a screenshot and it is not a cached PNG from the creator.

The create form shows a live share preview so you can see the card before you sign. After confirm, the same layout appears on the proof page and at /lock/{id}/opengraph-image.

Claiming

Only the beneficiary set at creation can call claim. The creator cannot pull early. Anyone can open the proof page; nobody else can move the tokens.

• Hard lock: after end, claim the full remaining balance.
• Vesting: claim whatever has accrued since the last claim. Repeat as it unlocks.

Claim from the proof page or from Your positions in the dashboard. If nothing is unlocked yet, the button stays disabled. A claim that would pay zero reverts.

Explorer

The Explorer lists public lock activity. Search by lock id, wallet, token, or transaction hash. It is a read surface, not a place to create positions.

Use it when a holder has a contract address and wants to know whether any Phanterium positions exist for that token, without needing a tweeted URL.

Streams

Streams are continuous unlocks for payroll, grants, and other flows that should move every second rather than sit behind a single cliff. Create them from the dashboard with a token, recipient, amount, and duration. CSV batch create is supported for many recipients in one sitting.

Streams can be topped up and, where the module allows, transferred. They do not rewrite an existing hard lock. A lock that has already unlocked stays unlocked if the same wallet later opens a stream.

Airdrops

Airdrops are merkle campaigns. Recipients claim against a root, either instantly or into a vest/stream so the drop does not hit the market in one block. After the claim window, leftover unclaimed tokens can be clawed back. Claimed balances cannot.

An airdrop is not an Phanterium token event. It is a distribution of whatever ERC-20 the campaign funded.

Escrow

Escrow funds a two-party deal on-chain. The buyer deposits. On delivery the funds release to the seller. If the deal fails, they refund. Both sides stay on the contract until that outcome. Escrow is not a time-lock of a meme allocation; it is a commercial hold.

Staking

Staking pools are permissionless. A publisher funds rewards. Stakers deposit and earn. Restake does not relock lots that already unlocked from a separate Phanterium position. Staking yield is not a substitute for a hard lock, and a hard lock is not a stake.

Fees and gas

Creating a lock pays a flat 0.0019 ETH (~$5) protocol fee, plus network gas in ETH. A split lock is 0.0034 ETH (~$9) flat, charged once on-chain however many wallets. If the creator was referred, 15% of that fee goes to the referral pool and the rest to the platform treasury the same split as a 0.0019 ETH lock. The fee never sits inside totalLocked. It cannot be claimed out of a position.

On Robinhood Chain, gas and the lock fee are both ETH (18 decimals). The fee is paid as msg.value on the create call no separate fee-token approve.

Protocol rules

• Tokens move into the vault at lock. They do not stay in the creator wallet.
• Valid schedule: start ≤ cliff ≤ end, end in the future, duration at least the protocol minimum.
• No cancel, no shorten, no reassignment after confirm.
• Only the beneficiary can claim.
• Fee and treasury logic cannot seize locked principal.
• If parameters change later, they apply to future creates, never to existing vault balances.

What a lock does not do

A lock is not a guarantee the token is safe. Honeypot, mint, tax, blacklist, and proxy upgrades on the token itself still exist. Phanterium only enforces the time schedule on the balance it received.

It is not custody beyond the contract. You keep your wallet. There is no support process that can move someone else’s position. Canonical domain only. Phanterium never asks for a signature that is not approve, create, claim, or an equivalent module action.

FAQ

Can a lock be cancelled?

No. Once the transaction confirms, amount and schedule are immutable. There is no admin cancel path over existing vault positions.

Is this the same as an LP lock?

No. LP lock belongs to the launchpad. Phanterium locks wallet tokens so they cannot be sold until the schedule allows.

What pays for gas?

ETH on Robinhood Chain. Protocol lock fees are also ETH (0.0019 ≈ $5 / 0.0034 ≈ $9) and are charged as msg.value on create, separately from gas.

Who can claim?

Only the beneficiary set at creation.

Is Phanterium custodial?

The contract holds tokens until claim. No human key can redirect them. You keep your wallet.

Does a lock stop the team from minting more tokens?

No. It only covers the amount deposited. If the token can mint, that supply is outside the vault.

What if I lock the wrong amount or the wrong beneficiary?

You cannot edit it after confirm. Read the preview against the wallet prompt before you sign.

Is there an Phanterium token?

No. Fees are ETH. There is no protocol coin and no promised airdrop of one.
