Built on Robinhood Chain

A calm place to hold yield.

The old way

A position you have to manage

Provide liquidity and the capital is earning, but it's also work: watching ranges, timing exits, deciding when to move it somewhere else. It rewards attention, not patience.

With HalcyonShares

A position that holds itself

Deposit once. The share you receive quietly gains value as fees are harvested in. There's nothing to watch, no range to defend, no reason to check it daily.

How it works

Four steps, and then nothing to do

01

Deposit

Send the pool asset to the vault. It's accounted explicitly in contract storage.

02

Mint

You receive HalcyonShares at the current price — a plain ERC-20, nothing else to set up.

03

Compound

Harvested fees raise the vault's assets. Share count stays fixed, so each one is worth more over time.

04

Redeem

Burn shares for the underlying at the current price, whenever you choose. No epoch, no queue.

What we're building

Two features, built carefully rather than many, built fast

HalcyonShares

A vault that mints a transferable ERC-20 against your deposit. Fee income raises the share price directly — no claim button, no separate rewards balance to remember.

Illustrative model only. Not a return we're offering, and not a guarantee of any kind.

Security

What the contract is designed to guarantee

GuaranteeHow it's enforced
No inflation attackA virtual share and virtual asset in every conversion, so a first depositor can't round a second depositor down to zero shares.
Donations don't repriceAssets are tracked in a storage variable, not read from the token balance. Sending funds directly to the contract changes nothing for holders.
Fee capped in codeMAX_FEE_BPS is a constant. The owner cannot raise the protocol cut past it — no vote, no upgrade path that changes it.
Principal untouchableThe sweep function is arithmetically limited to the balance above what shareholders are owed.
