SLIP39 vs BIP39 4 characters recovery seed words

[martijnw]

With BIP39 I can abbreviate every recovery seed word to just the first 4 characters. I know this is not recommended as storing the full words provides some form of error correction but my seed backup only supports 4 char recovery seed words.

I recently changed to using SLIP39 seeds and noticed these use a different word list as BIP39 seeds and was wondering ...

Can I abbreviate the SLIP39 recovery seed words to the first 4 characters like the BIP39 seed or is there a risk of collisions/errors?

Thanks in advance. I couldn't find this information anywhere online (wiki, docs, reddit, etc.) and do not know how to test this with just the word-list.

Sorry. I found my answer! "All words begin with a unique 4-letter prefix." It would be a good thing to add it to the wiki as many users will not be able to navigate GitHub for their answers.
