Technical Specification

About

This documentation describes the smart contracts and functions supported by the wormhole-eth-ledger-plugin.

Smart Contracts

Smart contracts covered by the plugin shall be described here:

Network Version Smart Contract Address
Mainnet V1 Wormhole Portal Token Bridge 0x3ee18B2214AFF97000D974cf647E7C347E8fa585

Functions

For the smart contracts implemented, the functions covered by the plugin shall be described here:

Wormhole Portal Token Bridge completeTransferAndUnwrapETH 0xff200cde
None*

* encodedVm parameters are not parsed because they are encoded in byte-packed and variable-length form, and the Ethereum Ledger app sends the data to the plugin in 32-byte chunks, which makes it difficult to handle those parameters that cross a chunk boundary.
