FAQPage Schema

How do I sign and broadcast cross-chain bridge transactions using multiple signer backends?▼

To sign and broadcast cross-chain bridge transactions safely, this Skill routes transactions across multiple signer backends like OWS, ethers, or browser wallets using a unified routing layer that automates nonce, fee handling, and EIP-712 signing.

How does EIP-712 typed data signing work for DLN orders?▼

EIP-712 typed data signing for DLN orders is implemented directly within the signing workflow, ensuring that structured data is securely signed and validated before the cross-chain transaction is broadcast.

Can I use MetaMask to sign deBridge swap and bridge transactions?▼

Yes, you can use MetaMask and other browser wallets to sign deBridge transactions, as the Skill routes to the appropriate signer based on your environment and supports both bridge and same-chain swap workflows.

Do I need to handle ERC-20 approvals manually before signing deBridge transactions?▼

No, you do not need to handle ERC-20 approvals manually; the Skill automates ERC-20 token approvals within its bridge and swap workflows to provide a safe, end-to-end signing process.

What is the best way to sign a deBridge transaction generated from an MCP environment?▼

The best way to sign a deBridge transaction from MCP is to feed the create_tx JSON into the signing workflow, which then allows you to select the appropriate signer to securely sign and broadcast the transaction.
