Papyrus

Papyrus is an ONFT1155 contract that's a 1-n NFT and can be transferred across chains.

Overview

Papyrus is an ONFT1155 contract that's a 1-n NFT and can be transferred across chains. It's basically SBT so can't be transferred to another wallet by the owner. It can be transferred to same wallet address on another chain or by an authorized transferrer (e.g. Obelisk) to another wallet.

Buying a Papyrus

A papyrus is needed for staking 1 NFT when entering a draw in Obelisk. To get papyrus NFTs, you can call buy() with _quantity * price ETH. FYI, price can be updated by owner.

The amount paid is transferred to treasury, which can also be updated by owner.

Sending Across Chain

Papyrus NFTs can be sent across chain via sendFrom() or sendBatchFrom(). For more information on how ONFT1155 works, refer to https://layerzero.gitbook.io/docs/evm-guides/code-examples/onft-overview/1155.
