This program was initially built during Solana v1.8.0. A closed source version is actively maintained and updated for Shadowy Super Coders. I will not be sharing those updates.

Yes, I do know this program does not use Metaplex's new "Collections" feature. No, I will not implement it in this open source repository. Feel free to open a PR with the changes if you'd like.

Staking Setup + Commands

Reward token

• NOTE: Only have to do this in development. In production, the reward token should already exist and you just have to transfer some into the vault later.

spl-token create-token --decimals 0

• NOTE: Any decimal spl token will work. Just using 0 for development purposes.

spl-token create-account <mint>

• NOTE: replace with the returned mint address from above

spl-token mint <mint> 1000000

Proof token

• NOTE: This should be a 0 decimal token. Only mint the number based on however large your NFT collection is. You can mint more if needed, but it shouldn't be necessary.

spl-token create-token --decimals 0

spl-token create-account <mint>

spl-token mint <mint> 10000

Set admin, proof_mint and reward_mint variables in program/src/lib.rs

cd program && cargo build-bpf

• NOTE: If cargo build-bpf doesn't work for you, run rm -rf ~/.cache/solana and then re-run the build command again. This should force solana to re-download and link the bpf utilities.

Deployment will cost about 3.31 sol

solana program deploy /path/to/nft-staking-v2/program/target/deploy/staking.so

Set reward_mint, proof_mint and program_id variables in client/src/main.rs

Run commands below in client directory

cargo build

Generate vault and transfer reward+proof tokens into the vault

cargo run -- generate_vault_address -e dev -s /path/to/deployer/id.json --min_period 60 --reward_period 10 --bonus_percentage 0 --bonus_period 30

• NOTE: periods in seconds
• NOTE: You can use decimals for reward period, min_period, bonus_percentage, and bonus_period. If you do use decimals, do extensive testing to make sure you get the expected amount in rewards and the timing is all correct.

spl-token transfer <reward_mint> 1000000 <vault-address> --fund-recipient

• NOTE: second address is the vault address returned from generate_vault_address cmd

spl-token transfer <proof_mint> 10000 <vault-address> --fund-recipient

• NOTE: second address is the vault address returned from generate_vault_address cmd

Add candy machine ID to whitelist

cargo run -- add_to_whitelist -e dev -s /path/to/deployer/id.json --reward 1 --maxreward 30 --candy_machine <candy-machine-creator-address>

• <candy-machine-creator-address> is the first creator address on the NFTs in your collection. This should be a creator with 0% share.

Client commands

cargo run -- stake -e dev -s /path/to/deployer/id.json --nft <nft-token-address>

• Stakes your NFT into the program vault, gives you a proof token back

cargo run -- stake_withdraw -e dev -s /path/to/deployer/id.json --nft <nft-token-address>

• "Claims" your tokens on your nft without unstaking

cargo run -- unstake -e dev -s /path/to/deployer/id.json --nft <nft-token-address>

• Unstakes your NFT and claims tokens at the same time

• NOTE: Wait 60s before unstaking/claiming, as the min_period above is set to 60s. You can set this to 0 or 1 if you'd like users to instantly claim or unstake

cargo run -- withdraw -e dev -s /path/to/deployer/id.json --amount 10

• NOTE: This is an admin-only command that lets you withdraw your reward tokens out of stake vault. This is a failsafe in case you need to kill this staking program and create a new one.
