Referral Reward Batch Distributor (Base)

WHAT IT DOES

This tool enables projects to batch distribute referral rewards to multiple referrers in a single transaction on Base. Instead of sending rewards to each referrer individually and paying gas for every transfer, it combines all referral payouts into one call to a shared batch-sender contract. The tool reads your token balance, allowance, and the current gas price before submitting the transaction. You specify the token contract address, the decimals, an optional program name, and a list of referrer addresses with per-referrer reward amounts. The tool computes the total tokens to distribute, checks your balance, verifies you have sufficient allowance for the sender contract, and submits one transaction that pays all referrers atomically. If allowance is insufficient, the tool automatically requests approval before sending. This is a true push distribution — referrers receive their rewards directly without any claim action required. Base's low transaction costs and fast finality make it ideal for referral program distributions with many participants.

HOW TO USE

Connect your EVM wallet via the BotGentz wallet bridge. Select Base (chain ID 8453) from the network dropdown (or any EVM chain). Enter the token contract address and its decimals. Optionally enter a program name for record-keeping. In the text area, list each referrer on a separate line with their address and the reward amount to send, separated by a comma. Amounts should be in base units (not including decimals). Click "Review rewards" to see your token balance, allowance, the sender contract fee, and the total amount being distributed. The tool will display a warning if your allowance is insufficient. If everything looks correct, click "Distribute rewards" — your wallet will first ask you to approve the token spend if needed, then to confirm the batch transaction. Once confirmed, the tool shows progress and the final transaction hash with a link to Basescan. This is ideal for referral programs, affiliate payouts, and user acquisition rewards.

TECHNICAL MECHANISM

This tool uses the BotGentz shared bulk-sender contract registry, keyed by chain ID and ERC standard. It looks up `BULKSEND[String(chainId)].erc20` to get the sender contract address for the current chain. On Base (chain 8453), the sender contract is `0x956D760F8665358Ea1a9F11b82913020e5479376`. The tool creates a contract instance using `BGWallet.getSigner()` connected to the current chain's provider. It calls `fee()` and `owner()` on the sender contract live — no values are cached. It also instantiates the token contract using the ERC-20 ABI and checks `balanceOf()`, `allowance()`, and `decimals()` for your wallet. The tool computes the total token amount from the referrer list and verifies both your token balance and native balance (for the sender contract fee) are sufficient. If allowance is insufficient, it sends an approval transaction for the exact total amount (not unlimited) before the batch transfer. The batch transfer uses `batchSend20(address token, address[] recipients, uint256[] amounts)` on the sender contract, sending the contract fee as `msg.value` in native tokens. The sender contract then iterates the referrer list and transfers rewards atomically within the same transaction using `transferFrom` from your wallet. After confirmation, it logs gas usage using `receipt.effectiveGasPrice`.

WHAT IT CANNOT SEE

This tool cannot verify referral validity, eligibility, or referrer authenticity. It cannot confirm that the referrals are genuine or that the referrers meet the program's eligibility criteria. It cannot verify that the referral data has been properly validated by the project. It cannot confirm recipient wallet readiness or guarantee that referrers can receive ERC-20 tokens. The tool does not validate that the token contract implements the ERC-20 standard or has the required `transferFrom` function. It cannot detect front-running or mempool congestion. It cannot provide a cross-chain receipt or rollback mechanism. It also cannot verify that the decimals value you entered matches the actual contract decimals — the tool warns but does not automatically correct discrepancies. Projects should always validate referral data before distributing rewards.

PLEASE NOTE

This tool is EVM-only. It works on Base and other EVM chains where the BotGentz registry has an erc20 entry. It does not support Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The tool requires the token contract to be deployed on the chain and for the sender contract to have an erc20 entry in the registry. Always test with a small amount and a single referrer before distributing full rewards. The sender contract charges a fee in native tokens — ensure you have enough native balance to cover the fee. This is a push distribution — the sender pays all gas, referrers receive rewards without any action. Base offers significantly lower gas costs than Ethereum L1, making it ideal for large referral programs.
