Start here

Halcyon is a single-token staking protocol. You stake $HALO, your sHALO balance goes up one for one, and during funded reward periods you earn a share of the stated reward amount based on how much you hold and for how long. There is no vault strategy, no yield splitting, and no leverage — staked tokens sit in the staking contract until you withdraw them.

The short version. sHALO is your receipt and your reward weight. Rewards only exist when a period is funded. Exits are always available: free after a 14-day cooldown, or instant with a 5% fee.

Quick glossary

sHALO — your staked balance inside the contract, minted 1:1 when you stake. It is your claim on staked $HALO plus your reward weight.

Reward period — a stated amount of $HALO distributed over stated dates to all stakers, funded upfront from existing supply.

Cooldown — a 14-day wait you start voluntarily. When it completes, you withdraw with no fee. Cooldown amounts stop earning.

APR — an annualized comparison rate computed from the current reward rate and total staked. It changes whenever either changes.

How staking works

The contract tracks three numbers for your wallet: your active balance (earning), your cooldown balance (waiting to withdraw, not earning), and your claimable rewards. Staking moves tokens from your wallet into your active balance. Reward accrual is continuous — every second of a funded period, the period's reward rate is shared across all active balances proportionally.

Active balance

Earns during funded periods. Grows when you stake or cancel a cooldown. Shrinks when you start a cooldown or take an instant exit.

Cooldown balance

Set aside for a fee-free exit. Stops earning immediately. Withdrawable after 14 days, or cancellable back into your active balance any time before you withdraw.

03

Make your first stake

You need $HALO on Robinhood Chain and a small amount of ETH for network fees. The chain ID is 4663 — the app offers to add and switch networks for you.

  1. Connect your wallet

    MetaMask, Rabby, or any injected EVM wallet. Approve the network switch to Robinhood Chain when prompted.

  2. Approve $HALO

    The first stake needs a one-time token approval so the staking contract can receive your tokens. This is a separate wallet signature before the stake itself.

  3. Enter an amount and stake

    Your sHALO balance updates one for one after the transaction confirms. Reward accrual starts immediately if a period is active.

  4. Claim whenever

    Claimable rewards show live in the app. Claiming is its own transaction and sends $HALO straight to your wallet without touching your stake.

For a balance that still looks unchanged after confirming, open the transaction in Blockscout first, then refresh the app.

04

Rewards

Reward periods pay $HALO. Each period reserves a stated amount from existing supply and streams it over stated dates. Your share is your active balance multiplied by time held, relative to everyone else's. Total supply is fixed — rewards are funded, never minted.

How claiming works
The app shows the $HALO your wallet can claim. Claiming is a separate transaction and leaves your staked balance in place. Later distributions pay only the additional amount allocated to you.
No reward amount shown?
That wallet has nothing accrued from the current period. Balances only earn while a funded period is running, and cooldown balances never earn.
Rates can change between periods
A completed period may show a backward-looking annualized rate. It describes that period only — each new period states its own amount and duration.
05

Exits and cooldown

Cooldown exit · 0%

Start the 14-day cooldown for any part of your active balance. That amount stops earning immediately. After 14 days, withdraw it fee-free. You can cancel before completion and the amount returns to earning.

Instant exit · 5%

Unstake immediately from your active balance. The configured 5% fee is deducted and the rest returns to your wallet in the same transaction. The exact amount after the fee is shown before you sign.

Both exits are always available while the contract is live — there is no lockup you didn't choose, and no permission needed from anyone.

06

Fees, rates, and APR

Staking is free. Claiming is free. The only protocol fee is the 5% instant-exit fee, which goes to the treasury address published below. Cooldown exits carry no fee. Your wallet shows the Robinhood Chain network fee (paid in ETH) before every signature.

The APR shown in the app annualizes the current reward rate against the current total staked. It moves whenever either number moves — more total staked means a lower APR at the same funding, and a new period changes the rate entirely. It is a comparison figure, not a promise.

$HALO rewards are paid in $HALO. The token's market price can fall while you stake, and a high APR in token terms can still be a loss in dollar terms. Staking does not protect you from price movement.

07

Risks

Smart contract risk
The staking contract follows a widely used pattern, but it has not been audited by a third-party firm. A bug or exploit could cause loss of staked tokens. Never stake more than you can afford to lose.
Token risk
$HALO is a memecoin. Its price is volatile and can go to zero. Rewards denominated in $HALO inherit that volatility fully.
Reward funding
Rewards exist only for funded periods. If no new period is funded, staking earns nothing until one is. Past periods do not predict future ones.
Liquidity risk
Exiting the stake returns $HALO to your wallet, but selling that $HALO depends on market liquidity at that moment.
Network risk
Robinhood Chain outages can delay transactions, and the chain screens transactions for compliance — a restricted address can have transactions refused before they reach the chain.
