[PIP-7] Expand to 8 chains with "Give" function

Summary

This proposal aims to:

Launch XEN-POP stake pools on all chains XEN Crypto is on, given there are no technical barriers. Other than Ethereum, XEN Crypto is currently on BNB Chain, Polygon, Avalanche C, Ethereum PoW, Moonbeam, Evmos, Fantom, and Dogechain.

Create a Give token (%) function on popcorndao.finance to give token stakers the option to nominate a user-specified amount of their tokens to a donation pool upon unstaking.

XEN-POP Stake Pool Economics:

APY: variable POP rewards: 100,000 POP spread across the 8 chains listed below Chains: BNB CHain, Polygon, Avalanche C, Ethereum PoW, Moonbeam, Evmos, Fantom, and Dogechain Reward window: 8 weeks (no new stakers after 8 weeks) Minimum XEN required: $100+ equivalent (using price oracle) Rewards vesting: 10% on unlock, 90% vesting linearly over 365 days Read the full Popcorn Improvement Proposal [PIP-7], including background, rationale, benefits, and linked discussions at: https://forum.popcorn.network/t/pip-7-expand-to-7-chains-with-give-function/799
