Do you know the current status of ABIEncoderV2? I want to know the current status of ABIEncoderV2

  • Live projects using ABIEncoderV2 right now

  • Restriction on the normal encoder

  • Risks of using ABIEncoderV2

As far as I know, ABIEncoderV2 still needs 'experimental' and that means officially not yet ready to the production level.

I know 0x is using https://github.com/0xProject/0x-monorepo/search?q=ABIEncoderV2%3B&unscoped_q=ABIEncoderV2%3B

and we can't use arrays as arguments in function

Do you know anything else?

As you mentioned, ABIEncoderV2 is currently in experimental state. This means that the creators do not vouch for its use in production.

Additionally, there have been two critical bugs(1, 2) found in Solidity surrounding ABIEncoderV2 within the last 3 months (at the time of writing), one being just 4 days ago.

Finally, auditing firms such as Zeppelin have noted the use of ABIEncoderV2 as a "High Severity" item, as they believe it is not ready for production.

With that said, teams like 0x and dYdX are using it in production and have been fine thus far. If you are using ABIEncoderV2 in production, try to limit its use to only necessary items, and attempt to write as many tests as possible for the affected code.
