Zircuit WETH Batch Sender

WHAT IT DOES

This tool enables you to batch send WETH (Wrapped Ether) from your wallet to multiple recipients in a single transaction on Zircuit. Instead of sending WETH to each recipient individually and paying gas for every transfer, it combines all transfers into one call to a shared batch-sender contract. The tool reads your WETH balance, allowance, and the current gas price before submitting the transaction. You specify the WETH contract address, the decimals (usually 18), and a list of recipient addresses with per-recipient amounts. The tool computes the total WETH to send, checks your balance, verifies you have sufficient allowance for the sender contract, and submits one transaction that distributes WETH to all recipients atomically. If allowance is insufficient, the tool automatically requests approval before sending. This is a true push distribution — recipients receive WETH directly without any claim action required. WETH is the ERC-20 representation of ETH, required for interacting with many DeFi protocols and smart contracts.

HOW TO USE

Connect your EVM wallet via the BotGentz wallet bridge. Select Zircuit from the network dropdown (or choose the appropriate chain where Zircuit is deployed). Enter the WETH contract address for the current chain (often the canonical WETH9 address). Set the WETH decimals (18 for standard WETH). In the text area, list each recipient on a separate line with their address and the amount of WETH to send, separated by a comma. Amounts should be in base units (e.g., 1000000000000000000 = 1 WETH with 18 decimals). Click "Review batch" to see your WETH balance, allowance, the sender contract fee, and the total amount being sent. The tool will display a warning if your allowance is insufficient. If everything looks correct, click "Sign & send batch" — your wallet will first ask you to approve the WETH spend if needed, then to confirm the batch transaction. Once confirmed, the tool shows progress and the final transaction hash with a link to the block explorer.

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. 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 WETH contract using the ERC-20 ABI and checks `balanceOf()`, `allowance()`, and `decimals()` for your wallet. The tool computes the total WETH amount from the recipient list and verifies both your WETH balance and native balance (for gas fees and 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 recipient list and transfers WETH atomically within the same transaction using `transferFrom` from your wallet. After confirmation, it logs gas usage using `receipt.effectiveGasPrice`. The tool does not wrap/unwrap ETH — you must have WETH already in your wallet.

WHAT IT CANNOT SEE

This tool cannot verify whether the WETH contract address you provided is the canonical WETH for Zircuit — if you enter a bridged or fake WETH address, the tool will send that token instead of real WETH. It cannot verify WETH wrapping/unwrapping status or confirm that your WETH is properly backed by native ETH. It cannot confirm recipient wallet readiness or guarantee that recipients 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. Most importantly, this tool sends WETH, not native ETH — ensure you have WETH balance, not just ETH.

PLEASE NOTE

This tool is EVM-only. It works on Zircuit 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 WETH 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 recipient before sending large batches. The sender contract charges a fee in native tokens — ensure you have enough native balance to cover both the fee and gas costs. This is a push distribution — the sender pays all gas, recipients receive WETH without any action. WETH is not the same as ETH — recipients will need to unwrap WETH to ETH if they want native ETH.
