Onchain Lions and RHEarn Explained: How NFT Holders Earn Stock Token Rewards on Robinhood Chain

Most NFT ‘staking’ asks holders to transfer their NFT into a contract in exchange for a project token that has to find buyers. Two problems follow. The holder gives up custody, which breaks marketplace listings and creates a single point of failure. And the reward token’s value depends on a market that the project itself is creating.

RHEarn, launched on Robinhood Chain mainnet in September 2026, changes both variables. The Lion never leaves the holder’s wallet, and the rewards are Robinhood Stock Tokens, assets that exist independently of the project and track real equities. It is a yield model built specifically around what Robinhood Chain makes possible.

Activation is a single on-chain transaction to the LionActivation contract that records your Lion as active. The contract only ever reads the collection’s ownerOf; it never calls transferFrom, so it needs no approval on your NFT and cannot move it. Up to ten Lions can be activated in one batch transaction. A small activation fee in ETH is paid at that moment, with 75 percent going to the reward pool treasury and 25 percent to operations.

Because there is no custody, there is also no lock period. You can list an active Lion on OpenSea, and if it sells, the buyer simply owns an active Lion. Deactivation is available at any time.

The reward pool is funded from two sources: activation fees and four percentage points of the collection’s 8 percent creator royalty on secondary sales. Pool ETH is periodically swapped into Stock Tokens, and each funding creates a new seven-day epoch in the RHEarnRewardDistributor contract. Rewards stream linearly across the epoch and are split among active Lions according to their weight.

Which Stock Token pays out can rotate epoch to epoch, so a holder’s claim history may include several different tokens. Lifetime earnings per wallet are public and shareable from the earnings page on RHMints.

Every Onchain Lion carries a Rarity trait, and RHEarn turns that trait into a reward weight. The weights are fixed in the contract bytecode rather than set by an admin transaction, which keeps them transparent and cheap to verify.

Rewards are claimable within a block or two of an epoch being funded; there is no need to wait for the epoch to finish. Claims require that the caller currently owns the Lion, not merely that they activated it. This is what makes the system safe to combine with open marketplace trading: a seller cannot drain accrued rewards after transferring the NFT, and a buyer inherits the Lion’s earning position.

The RHMints Lions Portal shows every Lion you hold, its activation state, its accrued rewards, and one-click claim and claim-all actions. The stats panel shows the collection-wide picture: active Lions, pool balance, and the current epoch.

RHEarn does not turn a Lion into a guaranteed return. Reward size depends on pool funding, which depends on activation fees and royalty volume. Stock Token prices move with the underlying equities. Smart-contract risk exists even with a non-custodial design. The right way to assess it is to read the contracts on Robinscan, look at how many Lions are active, check the pool balance and epoch history, and compare a Lion’s rarity multiplier with its price in the NFT Finder.

RHMints provides the tools for that analysis. It does not provide financial advice.
