- Also do some renamings and comment improvements:
transfer method -> type
- Remove integration tests since we no longer support direct calls to USV3 executor, even for testing.
- Renamed ExecutorTransferMethods to TokenTransfer to avoid leaking information about how the transfer happens into the executor. The executor shouldn't care if there are multiple methods or one single method that takes care of everything.
- Also renamed TransferMethod to TransferType to match the rust encoding
- This arbitrary sender should be same, since the sender is always set to be msg.sender from within the contract (no calldata can be sent specifying otherwise). This is just used to circumvent msg.sender being the pool/protocol during callbacks.
- Properly decode, update tests with proper decoding
- Added test case for each transfer method
- Also fully tested permit2 transferFrom and it works perfectly.
NOTE:
UniswapV3 doesn't support NONE as a transfer method.
TODO:
- Fix integration tests once encoding is implemented.

Rollback some of the Ekubo's Executor changes to a previous version to use the generic callback logic using transient storage
Took 1 hour 25 minutes
Took 13 seconds
With this, we don't need the univ3 specific method in the router contract. This should be flexible enough for most protocols that integrate
TODO: is this safe enough??

Curve pools use a different address from ETH (native token)
- Pass Chain into the SwapEncoderBuilder and SwapEncoder
- Add native_token_curve_address and native_token_address to CurveSwapEncoder
- Added integration test for this curve case

ENG-4306 Took 1 hour 4 minutes
Took 11 seconds
We don't need to use all the functionalities of the Curve Router, only the swap type 1 (exchange). By bypassing the router we can save gas on 2 token transfers and with smaller calldata
A nice side effect is that the executor is much more readable and understandable now

- To match the other executor inits and to not leak information about ICore into the deployment script.
- Also fix fork block of tests. This had been temporarily changed to test the Ekubo executor. For some reason, vm.rollFork is not working in this case. Skip the Ekubo integration test for now (we know it runs with the correct block, where the pool we call is actually already deployed)
- add integration test
- cannot directly call _handleCallback from the locked method of the tycho router because of bytes memory to bytes callback conversion
- Rename to EkuboPoolKey because of conflict with USV4 pool key
- Bonus: fix bug where input token to swap method must be ERC20 (we should also support ETH)
- Needed to take pool code init hash as input param for executors
- Added tests for ethereum. Will test base on-chain.
- Important note: Pancakeswap uses their deployer instead of their factory (this is a different address) for target verification.
- This factory is not the same for Ethereum and Base, so Base txs were failing when verifying pool addresses.
- I've double checked that we don't have this problem for Balancer V2 - the vault address in the same on Base and on Ethereum Mainnet.
- Only for single swaps
- Used USV4 for this because it's the only DEX we support that allows native ETH swaps
- For Native ETH input single swaps, we need to properly check the remaining amount (we were treating them wronly like ERC20 tokens)
- For Native ETH output single swaps, we were passing the incorrect currency (the settle always needs to be the out token and the take always needs to be the in token, this should not depend on the zeroForOne value).
The selector and executor are decoded inside this function now.
For Uniswap V3 I had to manually slice the msg.data from uniswapV3SwapCallback to get the data that matters for the callback
