Technical overview

What $BLOX is, how it is built, and how to verify each claim on Robinhood Chain (chain id 4663). Written for reviewers, wallets, and anyone doing due diligence.

What it is

$BLOX is a memecoin launched on the Bucket launchpad on Robinhood Chain on 2026-09-13. Trading fees are split on terms fixed at launch: most of every fee is paid to holders in RBLX, the tokenized stock on the chain, and part of it accumulates inside the token contract as a redeemable RBLX reserve. There is no team allocation, no mint function, no owner, no pause, no blacklist, and no transfer tax. The website is read-only and holds no keys.

Token contract facts

Selectors present: name, symbol, decimals, totalSupply, balanceOf, transfer, transferFrom, approve, allowance, burn(uint256), creator(), backingAssets(), backing(), isBacked(), redeemableFor(uint256), redeem(uint256,address).
No owner(), no mint, no pause, no blacklist, no fee-on-transfer. A 1,000 BLOX transfer was simulated with eth_simulateV1 and moved exactly 1,000 BLOX.
backingAssets() returns [RBLX]. backing() equals the contract's RBLX balance. redeem(amount, to) burns BLOX and pays RBLX pro rata.
Total supply is fixed at 1,000,000,000. 81,632,653 BLOX were burned at graduation; the buyback leg burns more on every payroll.

Fee route (immutable, from registry.termsOf)

Every swap on the locked pool pays a 3% fee. When the splitter collects, the fee is divided: 55% to holders (paid in RBLX by Bucket's payout engine), 15% into the token's RBLX reserve, 10% buyback and burn, 5% back into the pool, 15% to the creator wallet. Bucket's protocol take is applied inside the engine legs. These terms cannot be changed by anyone after launch.

Launch and graduation

Launch: 2026-09-13, 09:28 UTC, through the Bucket factory. 100% of supply went to the curve; nothing was pre-allocated.
Graduation: block 62,302,190, transaction 0x7f7d6c169bc40c5b…. The curve sent 204,081,632.72 BLOX and 5,000 USDG into the Uniswap v4 pool through the locker and burned 81,632,652.99 BLOX.
Liquidity is held by the locker contract, which has no withdrawal function. The position is full range.
Payouts: Bucket's distributor pushes RBLX to holder wallets once a wallet accrues about $2. The first pushes are listed on the proof page with transaction hashes.

Security model

All contracts are Bucket launchpad templates shared with every launch on the platform; $BLOX deployed no custom code.
No party holds admin rights: no owner, no upgrade path, no pause, immutable fee terms, permissionless fee collection.
The website reads the chain and holds no keys, custodies nothing, and never asks for a wallet connection except the optional payroll button, which sends one user-approved collect() transaction from the user's own wallet.
The symbol BLOX is shared by unrelated tokens created on this and other chains after this launch. The canonical contract is the one listed above and on Bucket's launch page.
