Send via LayerZero

WHAT IT DOES

This tool enables you to send tokens between different EVM-compatible blockchains using the LayerZero protocol, an omni-chain interoperability network. It reads your token balance on the source chain, checks your allowance for the LayerZero bridge contract, and handles the approval process automatically if needed. The tool then submits a transfer transaction to the LayerZero bridge, locking your tokens on the source chain and minting wrapped tokens on the destination chain.

The tool supports multiple EVM chains including Ethereum Mainnet, BNB Smart Chain, Polygon, Arbitrum, and Optimism. It allows you to specify both the source token address and the destination token address, giving you full control over which tokens you bridge and where they go. LayerZero's ultra-light architecture provides secure and efficient cross-chain messaging without the need for a trusted validator set, making it one of the most flexible interoperability solutions available.

HOW TO USE

Connect your wallet using the "connect" button. The tool will display your current chain ID, wallet address, and token balance once you enter a token address. Enter the token address you wish to send from the source chain, the destination chain ID (e.g., 101 for Ethereum, 102 for BSC, 103 for Polygon), the destination token address, and the amount you wish to send.

Review the transfer summary showing the token amount and destination chain, then click "send via LayerZero" to start the process. If your allowance is insufficient, the tool will automatically request approval for the bridge to spend your tokens. After approval is confirmed, it will submit the transfer transaction. The tool will wait for confirmation and display the transaction details on the appropriate block explorer. After the transaction is confirmed on the source chain, your tokens will be processed by LayerZero's oracle and relayer network and will appear on the destination chain. This process typically takes minutes, depending on network congestion and the LayerZero infrastructure.

TECHNICAL MECHANISM — LAYERZERO ULTRALIGHT TRANSFER

The tool interacts with the LayerZero Token Bridge contract, which implements the sendTokens() function. This function takes the token address, amount, destination chain ID, recipient address (as a 32-byte bytes32 value), minimum amount, and adapter parameters. The bridge contract locks the tokens on the source chain and emits a message containing the transfer details. This message is observed by LayerZero's oracle network, which provides the block header proof, and the relayer network, which delivers the transaction data.

Unlike traditional bridges that rely on a centralized validator set, LayerZero uses a combination of oracles and relayers that operate independently. The oracle supplies the block header hash, while the relayer provides the transaction proof. The destination chain contract validates the message by verifying both the oracle's block header and the relayer's transaction proof, ensuring that the message is authentic and cannot be forged. This ultra-light architecture allows LayerZero to support a wide range of chains without requiring a trusted third party, making it more decentralized and secure than many traditional bridges.

WHAT IT CANNOT SEE

This tool cannot estimate exact gas costs without a live RPC call, and gas prices on the source chain may change between quoting and execution. It cannot guarantee bridge finality times — while typical transfers take minutes, network congestion or oracle/relayer delays may extend this time. The tool cannot verify the bridge contract address is correct beyond the pre-configured mapping, and if the mapping becomes outdated, the transaction could fail or be sent to the wrong contract. It cannot cancel a transaction once submitted, and if the transaction fails due to gas issues, approval errors, or contract issues, you may still pay gas fees. The tool cannot handle bridging from or to non-EVM chains, as LayerZero supports many non-EVM chains but the wallet bridge is EVM-only. It also cannot bridge tokens not supported by the LayerZero bridge, and it cannot ensure the destination token address is correct for the target chain.

PLEASE NOTE — EVM CHAINS ONLY

This tool works exclusively with EVM-compatible chains supported by LayerZero, including Ethereum Mainnet, BNB Smart Chain, Polygon, Arbitrum, and Optimism. It does not support bridging to or from non-EVM chains such as Solana, Aptos, or Sui, even though LayerZero itself supports them. Always verify that the source and destination token addresses are correct for their respective chains. LayerZero tokens on the destination chain are often wrapped versions of the original token — ensure you are using the correct wrapped token address for your intended use case. Using the wrong token address may result in permanent loss of funds.
