user88340: I'm playing with OP_CHECKSEQUENCEVERIFY.
Here is my transaction that I'm trying to spend:

https://tchain.btc.com/e79d469698915aa6724288ae3a4141a31706d081f39fb7fd0b956a73a9044b22

which has the folowing redeem script:
2 OP_CHECKSEQUENCEVERIFY f45d94733d430261962932e0c847075195916a04 OP_CHECKSIG

But got an error when I  broadcast it (after two block confirmations left):
mandatory-script-verify-flag-failed (Non-canonical DER signature) (code 16)

I have no issues to spend transaction if I:

Just specify 2 CHECKLOCKTIMEVERIFY (can spend anyone)
With standart transaction HASH160 f45d94733d430261962932e0c847075195916a04 OP_EQUAL

but none with combination of them.
Here is a signed transaction:

Can someone explain me what I'm doing wrong?
P.S. With the folowing redeem script (OP_DROP added)

2 OP_CHECKSEQUENCEVERIFY OP_DROP f45d94733d430261962932e0c847075195916a04 OP_CHECKSIG

I got another error 
(Script evaluated without error but finished with a false/empty top stack element) (code 16)

I got

Can someone spend it? 

user60443: You must provide a scriptSig that, when executed with scriptPubKey results in a true (or any nonzero item) on the stack (and passes all verification ops).
The scriptPubKey you need to satisfy (with a scriptSig) is:
2 OP_CHECKSEQUENCEVERIFY f45d94733d430261962932e0c847075195916a04 OP_CHECKSIG 

(note this is not the redeemScript)
There main problem is:
OP_CHECKSIG is looking for a public key, but you have provided a script hash: f45d94733d430261962932e0c847075195916a04. This will never be satisfied so this transaction output is not spendable.
If you want to use the same redeemScript as before, you probably want the following scriptPubKey:
2 OP_CHECKSEQUENCEVERIFY OP_DROP HASH160 f45d94733d430261962932e0c847075195916a04 OP_EQUAL
Note the OP_DROP because the OP_CHECKSEQUENCEVERIFY leaves the 2 on the stack.
In order to spend this, you must provide any signatures and the redeemScript whose hash equals f45d94733d430261962932e0c847075195916a04.
Update:
The redeemScript is still wrong. Instead of 03e8546cfe53ca9014f6a352bc2e5c1f7cec1f5b344c73d4db3ed3b8f075d5c9ef, try 0014e17bbad678e82f8188099a351170c3e0efd4011b. This is the P2WPKH script you used previously in https://tchain.btc.com/46894d9dd5e20147826523b1a3ac8e8c5c64603338430d04bd6f5846af2bb9b4. Also note this is a segwit script so it will look for the signature and pubkey in the witness data: https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#p2wpkh
