Cool Things

• configurable keccak backend

Features

• serde - adds serde support to VAA types. Unlike previous iterations of the SDK, this support is for JSON only. We do not use serde for binary encoding/ decoding
• anchor - enables the anchor-lang keccak256 backend

Solana development

Solana devs should turn off serde and on anchor.

For Solana applications use - $ cargo add wormhole-vaas --features anchor
