Max transaction size

Should we put a max transaction size limit on mint into the ERC721 contract.

Not needed

ERC721 contract key

What is the status of the key used to set the contract?

Key should only be used for spinning up the contract and should be burned.

Oracle “Admin” functions

Do we need to enable the ability for Oracles to call various contract actions such as approve, transfer, mint, etc.

This can be performed in a couple of ways:
1 - The Oracles vote in who can execute the next essential action as follows:
Oracle 1 executes wrap action to mint using FIO obtid xxxxxxxx
Oracle 2 wrap action to transfer for the same FIO obtid to Alice
Oracle 3 executes wrap action for mint, but wrong recipient is provided. Trx goes to Alice defined by oracle 1 and 2

2 - The Oracles can sign the next transfer action as a multisig
This could be quite costly on the ethereum chain, but is possible to implement.
Example of multisig on ethereum https://github.com/christianlundkvist/simple-multisig/blob/master/contracts/SimpleMultiSig.sol

Decision: We do not want any Oracle admin functions.

Custodian “Admin” functions

Are there contract actions that should be exposed to Custodian “admin” approval?

• Pause switch is an admin function.

• Use case: refunds. If someone calls unwrap to the wrong address and it gets lost. We may want to enable the ability for Custodians to call 2/3+1 approval for a “mint” refund.

  • This can already be done by the Oracles calling wrap to a specific Ethereum address.

TBD: Are there any other contract actions that might be used for “admin” functionality?

Unwrap fee

Is there a fee for unwrap?

Yes. Unwrapping user pays the gas fee
