Cross-Chain Token Wrapper

WHAT IT DOES

Cross-Chain Token Wrapper is a DeFi tool that lets you wrap native tokens into bridged wrapped tokens or unwrap bridged tokens back to native using cross-chain token wrapper contracts. Token wrapping is a fundamental operation for cross-chain interoperability — it enables native tokens to be represented on other chains as wrapped versions that can be used in DeFi applications, swapped, or transferred. This tool reads your token balances, wrapper contract state, and bridge fees, then constructs and submits the wrap or unwrap transaction. It provides a preview of the token details — token address, operation, amount, destination chain, and bridge fee — before you execute, enabling secure and transparent token wrapping.

HOW TO USE

Connect your EVM wallet via the BGWallet bridge. Enter the wrapper contract address and the token address you want to wrap or unwrap. Select the operation — Wrap (native → wrapped) or Unwrap (wrapped → native). Enter the amount you want to wrap or unwrap. Optionally, enter a destination chain ID if you want to bridge the wrapped token after wrapping, and the bridge fee. Click "Preview Wrap" to see the wrapper contract, token, operation, amount, and bridge fee. Review the details carefully. Click "Wrap/Unwrap" to sign and broadcast the transaction. The tool provides a transaction hash for tracking and confirms the wrap operation.

TECHNICAL MECHANISM

The tool reads the token balance from the token contract using `balanceOf(address)` and the wrapper contract state using view functions like `wrappedToken()` or `getBridgeFee()`. It validates that the amount is positive and that the user has sufficient balance for the operation. When executing a wrap, the tool first approves the wrapper contract to spend the native token (if required), then calls the wrapper contract's `wrap` or `deposit` function. For unwrapping, it calls the wrapper contract's `unwrap` or `withdraw` function. If a destination chain is specified, the tool may also call the bridge function to send the wrapped token across chains. The entire operation is atomic — if any step fails, the transaction reverts. The tool estimates gas using `estimateGas` and displays the estimated cost before execution.

WHAT IT CANNOT SEE

This tool cannot guarantee that the wrapped token will be redeemable on the destination chain if the wrapper contract changes or the bridge network fails before the message is processed. Wrapped tokens are only as reliable as the bridge and wrapper infrastructure that supports them. The tool also cannot predict changes to the wrapper contract, such as upgrades or modifications to the wrap/unwrap interface, that may affect the operation. Additionally, the tool cannot verify that the wrapped token is accepted by the destination chain's ecosystem. Always verify the wrapper contract address and the wrapped token's status before executing. This tool is an aid for token wrapping, not a guarantee that the wrapped token will be redeemable.

PLEASE NOTE

EVM chains only. This tool relies on the BGWallet connector and will not function on Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The user is responsible for ensuring the supplied wrapper contract address is correct and that the contract supports wrap/unwrap functions. The fee must be paid in the native token of the source chain — ensure you have sufficient balance. Always verify the wrapper contract address and the wrapped token's status before executing. Not all tokens are supported by every wrapper — check your wrapper's documentation for supported tokens.
