[TASK] Best Practices: How to deploy a contract on a mainnet

[zavodil]

What is this for?

• Devs need clarification on how to deploy their contracts in prod. Mistakes may be critical here

Who needs to be involved?

• @thisisjoshford or @bucanero

Tasks to complete (can return to [x] these)

• [ ] Create a doc
• [ ] Publish
• [ ] Social media share
• [ ] Feedback / updates

Subjects:

• Testnet/mainnet, how to switch networks,near deploy, initial storage cost
• Create owner account in CLI / Near wallet. Owner account may be a multisig.
• Create contract account in cli: near create-account contract.<account-id> --masterAccount <account-id> --initialBalance 10
• 2FA is a contract too, it will overwrite and destroy any previous contract, don't try to enable 2FA on a contract
• If you want to perform an anonymous deployment: 1) create new account and fund it using a linkdrop/anonymous exchange account 2) build a binary file using docker (contract-builder https://github.com/near/near-sdk-rs/tree/master/contract-builder, example: https://github.com/zavodil/quizchain/blob/main/build_docker.sh
• User data stored in the contract state will increase minimal storage deposit, so consider storage deposits from users or subsidise your contract
• Create a method to withdraw contract rewards (NEAR Protocol allocates 30% of transaction fees to the contracts these transactions touched)
• Lock contract account as soon as you are ready near delete-key <account-id> <access-key>
