If you created a drop on Foundation and the site is now offline (404 everywhere), don’t panic.
Your NFTs are still fully mintable on-chain – whether they’re 1/1s or edition drops. I just did this with my Mystic Knights collection minted on 2023 (111 total uploaded, 73 sold, 38 left unminted). Here’s the exact step-by-step that worked perfectly:
Step 1: Find your contract
Go to Etherscan and open the contract address from your original Foundation drop (check your wallet history or old emails).
Example:
0x2704d7208fe80d4448027cf09b9bb11c3e81ddc7
Step 2: Check your permissions (Read Contract tab)
No wallet connected yet. Scroll and query these functions with the wallet you used to create the drop:
- owner() → should show your address
- isAdmin(your address) → should be true
- isMinter(your address) → if false, grant yourself the role (super common)
- numberOfTokensAvailableToMint() → shows how many are left
Step 3: Grant yourself MINTER_ROLE (Write Contract tab)
Connect your creator wallet.
Look for grantMinter (easiest):
- Paste your own wallet address
- Click Write → confirm gas
(If you only see grantRole, copy the MINTER_ROLE hash from the Read tab and use that.)
Wait for confirmation, then re-check isMinter -> now true.
Step 4: Mint the rest
Still on Write Contract, same wallet connected.
Find mintCountTo:
- count = number you want to mint (all at once or in batches)
- to = your wallet address (or any other address)
Click Write -> confirm.
Done. Tokens appear in your wallet instantly (IDs continue sequentially). Works exactly the same for both 1/1 drops and edition drops.
Why this works
Foundation was just a front end. The smart contract (NFTDropCollection) lives forever on Ethereum. As long as you’re the owner/admin, you control everything – even years later.
No extra mint cost, only gas. Metadata & royalties stay exactly as you uploaded them.
Quick note on “on-chain”: Minting through the contract gives you true on-chain ownership and supply control on Ethereum. The actual art files live on IPFS or Arweave (still decentralized & permanent), but the contract itself is fully on-chain and immutable; unless your pieces are generative on-chain art which even the images live on ETH's code since the images are written in code on ETH, this can be applied to other blockchains as well such as BTC and TEZ.
Safety tips
- Only use the wallet that originally created the collection
- Double-check you’re on the real contract (verified on Etherscan)
- Start with a small test mint (e.g. count=1) if you’re nervous
- After minting, list anywhere: OpenSea, Transient Labs, Manifold, etc.
This saved my remaining Mystic Knights pieces. If you’re in the same boat, you’re not stuck – the blockchain still works.
True on-chain ownership = the contract, your mint rights, and wallet control live forever.
Platforms come and go. Contracts don’t.
