Let's suppose, I already executed 48 Tx onchain and I signed an offchain Tx with nonce 49.
- I don't sign the offchain Tx with nonce, the transaction will be invalid because every Tx must have nonce to protect against replay attach.
- I make an onchain Tx with 49 nonce, the offchain signed Tx will automatically get void as network will not accept another Tx with similar nonce.
- I make an onchain Tx with nonce 50 (instead of 49 as stated above), my tx will stay in pending state until and unless a Tx with 49 nonce is not executed.
There are so many problems in Offchain signing of Tx. How to overcome these problems?
