Can I use the SDK to submit contract transactions?

Not yet, working on it!

Should I use the API versus SDK to construct deposit parameters?

We recommend using the API for the easiest way to query suggested deposit params.

What is the behavior of ETH / WETH in transfers?

Across liquidity pools are filled using WETH but, depending on the context, Across will sometimes send a user ETH and sometimes send a user WETH.

• If a bridge transfer is being sent to an EOA, the EOA will receive ETH (not WETH)

• If a bridge transfer is being sent to a contract, the contract will receive WETH (not ETH)
