Every market. One Zcash wallet. Now on BNB Chain. Sprout is the first Zcash-native launchpad and terminal on BNB Chain — launch, trade, cash out, in ZEC.

What Sprout is

Sprout lets Zcash holders use BNB Chain's memecoin markets without giving up their Zcash wallet. You fund from Zcash, see every price and balance in ZEC, earn rewards and payouts in ZEC, and cash out back to Zcash — optionally to a shielded address.

Every Sprout coin is a real Flap tax token on BNB Chain. Part of every trade deepens one shared $SPROUT/ZEC pool, part buys and burns $SPROUT, and the deployer can send their share to holders, to a Zcash wallet or as a donation to the Zcash Foundation.

Why 春笋

春笋 means spring bamboo shoots. The saying 雨后春笋 — “like bamboo shoots after rain” — describes things springing up everywhere at once. That is what a launchpad should feel like: plant a coin, grow the grove.

The names follow the plant. A new coin is a Seed (笋芽), a trading coin is a Shoot (春笋), and a graduated coin joins the Grove (竹林). The shared pool is the Grove, the buy-and-burn is the Rootstock (竹根), the public ledger is Nodes (竹节), and receipts are Stamps (印章).

How it works

  • 1. Bring ZEC in. Create a passkey Sprout Account and send ZEC from your Zcash wallet to a one-time deposit address. NEAR Intents 1Click converts it to BNB in your account. (Or connect a BNB wallet.)
  • 2. Plant or trade. Launch a coin in one transaction, trade Sprout coins on Flap, or trade any Flap token on the Terminal. Your passkey signs; the relayer pays gas and is reimbursed from your balance.
  • 3. Grow. Every trade pays a fixed 2% tax: the Grove, Rootstock, operations, and the deployer's choice — paid in ZEC.
  • 4. Cash out to Zcash. Sell and receive native ZEC at your transparent address in the same transaction, or choose a shielded payout with a stamp in the memo.
