GrowBlocks Goes Live on Robinhood Chain Mainnet With Nine NFT Collections as eFroglets Move From Linea

Disclosure: the Ledger's publisher, Shama, is the founder of efrogs and GrowBlocks. The Pond Street Ledger and GrowBlocks have the same owner. The on-chain counts in this story were read by the Ledger from Robinhood Chain and Linea on 21 October.

GrowBlocks, the browser game world that has run on Robinhood Chain testnet since September, now mints, sells and drops real NFTs on Robinhood Chain mainnet. Nine collections are live: eFroglets, the efrogs offshoot moving across from Linea, the OG Cube for Season 0 players, and award collections for seven games. Between the first mainnet deploy on 19 October and block 94,219,828 on 21 October, those nine contracts minted 635 NFTs, according to their Transfer logs.

The rest of GrowBlocks, its coins, plazas and launchpad, still runs on testnet. Season 0 ends there on 28 October, and the team says the rest of the world follows the NFTs to mainnet after that.

Games that pay in NFTs

Seven games now mint their awards on mainnet: LONG SHOT, a sniper duel game; SHOOTER PLAZA, whose collection covers the arena's street, co-op and maze modes; SLAM BLOCKS, one-on-one street basketball; CLAY RUSH; STARCROP TROOPERS; ROGBLOX; and ANTLANDS, an ant-colony war whose rival colonies are run by Sage, an AI model from Levanto Labs. Between them they carry 75 designs, from Kill Cards and medals to perks that change a match, with some rarer prints capped in number.

A player earns a piece by winning: a duel, a wave, a match. The game asks GrowBlocks' server to mint it, and it arrives in the player's game wallet, the one GrowBlocks creates at Google sign-in, with the network fee paid by GrowBlocks. LONG SHOT, for example, caps Kill Cards at five a day per player. Badges stay with the player who earned them; everything else can be sold or given away.

GrowBlocks lists 18 games on its play sheet, eight of its own and ten built by outside studios with its Dev Kit. ROGBLOX, STARCROP TROOPERS and ANTLANDS run on the Dev Kit, and ANTLANDS' first awards, minted on 21 October, were the first time a Dev Kit game earned, listed and dropped a mainnet piece end to end, the team said. A further game, Lily Hop, pays in USDG rather than NFTs: holders of an eFroglet compete for a weekly prize pot.

One market, priced in USDG

All nine collections trade on one market contract inside the game, in USDG, the dollar stablecoin used on Robinhood Chain. Game NFTs, a panel that opened on 21 October, lists each game's pieces with its logo and rarest card, and lets a player buy, sell, cancel a listing or drop a piece on the plaza. A dropped piece hops around the square until someone catches it. The first to catch it keeps it; if no one does, it returns to its owner after ten minutes.

On a 100 USDG sale, the seller receives 93 USDG. The market keeps 2 percent and the collection's royalty is 5 percent, according to the market's configuration. For eFroglets, the team says royalties from shop sales go into the Pond Pot, which is paid out every Monday to the top ten Lily Hop players who hold a frog. eFroglets also trade on OpenSea, which indexes Robinhood Chain.

At the time of writing no game piece was listed for sale and none had been sold. The 20 non-mint transfers on eFroglets and six on ANTLANDS were moves and plaza drops. The market is open; its first trades have not happened yet.

The eFroglets move from Linea

eFroglets are a 10,000-piece pixel collection that launched on Linea. Each Linea number can be claimed once, free, as the same number on Robinhood Chain, until 17 January 2027. The claim needs no ETH: a holder signs in, proves they hold the Linea frog with one signature, and the mainnet frog is minted to their game wallet.

Holders can also send the Linea copy to a mover contract, which burns it and marks the Robinhood frog as moved. Season 0 pays 50 XP for each moved frog, up to ten. By 21 October, 374 of the 10,000 numbers had been claimed on Robinhood Chain and 26 Linea frogs had been burned through the mover. Of the claims, 332 were made by the team's own game wallet in its first run of the claim on 19 October; the rest were claimed by holders.

Inside GrowBlocks a frog does more than sit in a wallet. A holder can make one a pet that follows their character around the plaza, drop it for others to chase, and use it to enter the Lily Hop rankings.

Season 0 carried over

The OG Cube, the numbered collectible for Season 0 players, was minted on testnet in claim order. On 20 October GrowBlocks gifted all 87 on mainnet, with the same numbers to the same wallets. Two Dev Kit game collections made the same move: 38 STARCROP and 20 ROGBLOX pieces earned during the season were minted on mainnet to the players who held them. Other testnet items, including karts, wearables and armoury pieces, stay behind, the team said.
