Game Tournament Prize Batch Distributor (Arbitrum One)

WHAT IT DOES

This tool enables game developers, tournament organizers, and esports leagues to distribute prize pools to winners in a single batched transaction on Arbitrum One. Instead of sending 50 individual transactions and paying gas 50 times, you paste a list of winner addresses and prize amounts, and the BotGentz bulk-sender contract distributes everything in one go. It supports ERC-20 tokens, ERC-721 NFTs, and ERC-1155 multi-tokens, plus native ETH through the same interface. The tool reads on-chain balances, verifies that your wallet holds enough of each asset to cover the total prize pool plus the contract's fee, and checks your transaction history to flag duplicates. It displays the contract's live fee, owner, and address before you sign anything so you know exactly what you are approving. This is designed specifically for gaming tournament prize distributions—where timely payouts are critical for player trust and retention—but it works for any bulk payment need, from esports leaderboards to community gaming events.

HOW TO USE

Connect your EVM wallet via the BotGentz bridge. The tool automatically detects Arbitrum One (chain ID 42161) and looks up the correct bulk-sender contract from the BotGentz registry. Enter the token contract address, choose the token type (ERC-20, ERC-721, or ERC-1155), and paste your winner list as one address and prize amount per line. Click "Parse list" to validate addresses and preview the total prize pool. The review panel shows the number of winners, total prize pool, token address, and the contract fee in ETH. When you click "Send batch," the tool performs a balance check per sender, not per row, ensuring the entire batch can complete before the first transfer. It then approves the sender contract for the exact total amount, not unlimited, and sends the batched transaction. Progress is shown throughout, including transaction confirmation. All state is in-memory and lost on reload—no data is stored. The tool is designed to handle large tournaments with hundreds of winners, making mass payouts practical and cost-effective.

BULK SENDER CONTRACT MECHANISM

Unlike claim-based airdrops where each recipient pays their own gas to withdraw, this is a true bulk-send tool: the sender pays once for the entire batch. The BotGentz registry provides per-chain, per-standard contract addresses. The tool reads the fee() and owner() methods live from the contract each time—never hardcoding fees because the owner can change them. It uses the contract's sendERC20, sendERC721, and sendERC1155 methods, passing the recipient arrays, amounts or token IDs, and the required fee as msg.value. The fee covers the contract's operational costs and is separate from network gas. The tool checks balances comprehensively: native ETH balance must cover the fee, and ERC-20 balance must cover the total prize pool. It walks through approvals sequentially and awaits each transaction, avoiding nonce conflicts that would occur if sends were fired concurrently. Post-EIP-1559, it uses receipt.effectiveGasPrice for accurate cost reporting rather than tx.gasPrice. For chains with different log limits, it chunks reads appropriately, halving ranges on failure. The contract owner is shown so you can verify the deployer before signing. The tool also reads token decimals dynamically to handle tokens with different precision correctly, and supports NFT prize distributions where winners receive unique in-game items or collectibles.

WHAT IT CANNOT SEE

This tool cannot verify off-chain tournament results, match outcomes, player rankings, or prize eligibility. It cannot prove that recipient addresses are correct, that winners are legitimate, or that the same player is not receiving multiple prizes via different identities. It cannot detect Sybil attacks or duplicate player identities. It cannot access private winner payment preferences, tournament rules, or eligibility criteria. It cannot recover funds sent to wrong addresses—the blockchain is final. It cannot see past the current block, and it cannot enforce business rules beyond what is expressed in the prize list. It does not store any data; all state is in-memory and lost on reload. It cannot verify that a player actually participated in the tournament, that matches were played fairly, or that rankings were calculated correctly. It cannot enforce prize distribution rules, handle tiebreakers, or automatically import results from gaming platforms. It cannot verify player identities, check for cheating, or validate that winners are eligible based on geographic restrictions, age requirements, or other off-chain criteria. It cannot refund prizes or reverse distributions if a player later disqualified.

PLEASE NOTE

This tool works only on Arbitrum One (chain ID 42161) with the BotGentz bulk-sender contract deployed. Other EVM chains like Ethereum, Optimism, Base, Polygon, BNB Chain, and others are supported by sibling tools—this specific tool is restricted to Arbitrum One. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. Always double-check the contract address displayed in the tool against the official BotGentz registry before sending. The tool is free and open-source; the contract fee is set by the owner and displayed live. Use at your own risk—you are responsible for verifying all addresses, prize amounts, and winner eligibility before signing any transaction. Prize distributions are final once confirmed on-chain. For tournaments with large prize pools, consider testing with a small batch first.
