✨ v1.1.0 has been released! ✨

[Elnaril]

This version comes with the support of the Universal Router TRANSFER function.

A couple of use cases:

1/ Swap and transfer to many recipients

Let's say you want to pay 100 USDC to several beneficiaries from a wallets having only some ETH.
You can now do it all in one single transaction by encoding:

1. one WRAP_ETH
2. one V3_SWAP_EXACT_OUT or V2_SWAP_EXACT_OUT
3. many TRANSFER

2/ Mass transfers

You can just make a lot of ETH or ERC-20 transfers in one single transaction and save a substantial amount of gas, depending on the number of recipients, compared to the standard one transfer per transaction.

In my tests, I sent 1 ETH to many recipients and got the following results:

Recipients	gas used	standard gas used	delta
6	192188	126000 (6 * 21000)	+ 53 %
12	244406	252000 (12 * 21000)	- 3 %
18	296756	378000 (18 * 21000)	- 21 %
24	348890	504000 (24 * 21000)	- 31 %
48	557986	1008000 (48 * 21000)	- 45 %

So, if it's not interesting for just a few transfers (53% increase of gas consumption compared to 6 standard transactions), it makes sense for more (the gas used is decreased by 45% for 48 transfers).

Other updates

The decoding of the "revert on fail" flag is now supported, and the way is prepared to encode UR functions that support it. For now, this SDK does not support any such function yet, as they are mainly NFT related ones.

This new version also adds support for encoding the execute() function without deadline.
