Update selectors database #45

Closed acuarica closed 5 months ago

acuarica commented 11 months ago

The current selectors database https://github.com/acuarica/evm/blob/32764c3f1e5d71c9366c6bf1c20b9e26b35850b9/selectors/functionHashes.json is quite outdated. Update this database to include more function and event signatures.

From #1

The user then can check out some of these APIs to do the hash lookup.

https://www.4byte.directory/ https://www.etherface.io/ API seems to be down https://openchain.xyz/signatures https://github.com/ethereum-lists/4bytes

A new 4byte database has been created https://github.com/acuarica/4byte from verified contracts from Etherum mainnet. This database should be imported into https://github.com/acuarica/sevm-4byte.

acuarica commented 5 months ago

Database selectors repo https://github.com/acuarica/sevm-4byte has been merged into this repo in 03d935f.

Thus, said repo has been deleted and its corresponding package https://www.npmjs.com/package/sevm-4byte has been marked as deprecated.

OpenChain API https://openchain.xyz/signatures allows the use to export the whole signature database, using the export endpoint, e.g.,

curl https://api.openchain.xyz/signature-database/v1/export > sigdb.txt

However, its size is currently 147M, which is too big to be embedded in the local selectors database.

The other alternative was to merge with our own 4byte database. The functions.json generator has been added here https://github.com/acuarica/4byte/commit/2732fa2b49a93eee32b6a39f3e9fbddc9ce36f95.

However, it is also too big, ~12M only the function signatures (without hashes).

So closing this, in favor of the new patch API
