Send via Hyperlane

WHAT IT DOES

This tool enables you to send tokens between different EVM-compatible blockchains using the Hyperlane protocol, a permissionless cross-chain messaging network with modular security. It reads your token balance on the source chain, checks your allowance for the Hyperlane bridge contract, and handles the approval process automatically if needed. The tool then submits a transfer transaction to the Hyperlane 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, Optimism, and Avalanche. It allows you to specify both the source token address and the destination token address, giving you full control over which tokens you send and where they go. Hyperlane's permissionless architecture allows anyone to deploy and secure a validator set, making it one of the most flexible and accessible 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 name (e.g., "ethereum", "polygon", "avalanche"), 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 Hyperlane" 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 Hyperlane's validator set and will appear on the destination chain. This process typically takes minutes, depending on network congestion and checkpoint intervals.

TECHNICAL MECHANISM — HYPERLANE PERMISSIONLESS CROSS-CHAIN TRANSFER

The tool interacts with the Hyperlane Token Bridge contract, which implements the sendToken() function. This function takes the token address, amount, destination domain (chain ID), recipient address (as a 32-byte bytes32 value), and metadata. The bridge contract locks the tokens on the source chain and emits a message containing the transfer details. This message is observed by Hyperlane's validator set, which is configured per chain and can be permissionlessly deployed.

Hyperlane uses a modular security model where each chain has its own validator set that can be customized by the chain's deployer. These validators reach consensus on the message and produce a checkpoint that proves the transfer occurred. The checkpoint is submitted to the destination chain's Hyperlane inbox, which verifies the validators' signatures and executes the corresponding transaction, minting the wrapped tokens to the recipient. The modular security model allows Hyperlane to support a wide range of security configurations, from trusted validator sets to fully decentralized sets, making it adaptable to different use cases and security requirements.

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 validator 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 Hyperlane supports many non-EVM chains but the wallet bridge is EVM-only. It also cannot bridge tokens not supported by the Hyperlane 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 Hyperlane, including Ethereum Mainnet, BNB Smart Chain, Polygon, Arbitrum, Optimism, and Avalanche. It does not support sending to or from non-EVM chains such as Solana, Cosmos, or Sui, even though Hyperlane itself supports them. Always verify that the source and destination token addresses are correct for their respective chains. Hyperlane 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.
