Gem Miner Staking

Stake $GEM on Base to earn yield and unlock Gem Miner's in-game earn + cashout system. The staking gate requires 25,000,000 GEM staked. No burn NFT required to stake.

Contracts (Base mainnet)

Contract	Address
$GEM token	`0xD3776969966B340d72d75731eF890A3Bc9F21bA3`
GemStaking	`0xff293DEc665949a3a1a80fBA6a602da3be702C1A`

Key Parameters

Unbond period: 7 days (requestUnstake → wait → withdraw)
Early exit fee: 10% folded back into the reward pool
Earn/cashout gate: 25,000,000 GEM staked
Rewards: from ForgeUpgrade fees — 10% of every forge burn routes to stakers

Check staking position

bankr "on Base, call balanceOf(address), earned(address), and pendingOf(address) on 0xff293DEc665949a3a1a80fBA6a602da3be702C1A with my wallet"

Returns: staked, earned (claimable rewards), pending (unbonding amount + unlock timestamp).

Check GEM balance

bankr "what is my GEM balance on Base for token 0xD3776969966B340d72d75731eF890A3Bc9F21bA3"

Stake GEM

Approve then stake in one shot:

bankr "on Base, approve 0xff293DEc665949a3a1a80fBA6a602da3be702C1A to spend [AMOUNT_WEI] of token 0xD3776969966B340d72d75731eF890A3Bc9F21bA3, then call stake(uint256) on 0xff293DEc665949a3a1a80fBA6a602da3be702C1A with [AMOUNT_WEI]"

Raw wei: 25M GEM = 25000000000000000000000000 (25 followed by 24 zeros)

Request unstake (start 7-day unbond)

bankr "on Base, call requestUnstake(uint256) on 0xff293DEc665949a3a1a80fBA6a602da3be702C1A with [AMOUNT_WEI]"

Withdraw after 7 days

bankr "on Base, call withdraw() on 0xff293DEc665949a3a1a80fBA6a602da3be702C1A"

Early withdraw (pays 10% fee)

bankr "on Base, call earlyWithdraw() on 0xff293DEc665949a3a1a80fBA6a602da3be702C1A"

Claim staking rewards

bankr "on Base, call getReward() on 0xff293DEc665949a3a1a80fBA6a602da3be702C1A"

Common amounts (raw wei)

GEM amount	Raw wei
25,000,000 (gate minimum)	`25000000000000000000000000`
50,000,000	`50000000000000000000000000`
100,000,000	`100000000000000000000000000`

Notes

No burn NFT required — anyone with GEM can stake
Rewards accrue continuously; claim anytime without unstaking
Early withdraw burns 10% — redistributed to remaining stakers
The 7-day clock starts on requestUnstake; you cannot re-stake the pending amount
Once staked past 25M, you unlock earn events and GEM cashout in-game at gemminer.app
