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"

| 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
