Project Description

This is part of the 'Sakutaro Poems NFT' art project, adapted for the Filecoin mainnet. Note: The development this time pertains only to the NFT portion on Filecoin. The website as a whole and NFTs on other chains are pre-existing.

Thirty-nine poems from Sakutaro Hagiwara's late self-selected collection, 'Shukumei,' have been inscribed on the blockchain as fully on-chain NFTs. These NFTs possess a mysterious property whereby their contents change depending on the owner.

How it's Made


  • Limited to 39 pieces.
  • Anyone can mint.
  • Poems written in SVG images are generated entirely on-chain.
  • The poem changes based on the owner's address.
  • SVG images are provided in the Object Display Standard format, converted to Base64.
  • Deployed on multiple chains, both EVM and non-EVM.

I used Hardhat to implement and test Solidity smart contracts and deployed them on the Filecoin testnet and mainnet. In the web app, I utilized ethers.js to connect to the MetaMask wallet, allowing for the retrieval and minting of NFT information.
