eth_getStorageAt using web3api

[zza]

I am attempting to migrate our applications from speedy nodes to web3api.

We need eth_getStorageAt to get implementation abi from proxy contracts. How can we use web3api to do so? Thank you.

this may help you:

runContractFunction can't get any data from smart contract ABI [NextJS]

example that should work: curl -X 'POST' \ 'https://deep-index.moralis.io/api/v2/0xe11b8e0243e3eed9df387ca279caad4d2b35951a/function?chain=rinkeby&function_name=uri' \ -H 'accept: application/json' \ -H 'X-API-Key: API_KEY_HERE' \ -H 'Content-Type: application/json' \ -d '{ "abi": [{"inputs":[{"internalType":"uint256","name":"id","type":"uint256"}],"name":"uri","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"}], "params": {…

Hi i think the code snippet you linked does not serve the same purpose.

For example, this proxy contract https://etherscan.io/address/0x7d2768dE32b0b80b7a3454c06BdAc94A69DDc7A9#code

has an implementation slot (EIP-1967): IMPLEMENTATION_SLOT = 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc;

using eth_getStorageAt with speedy node, we can easily get the implementation at the specified storage slot.

how do you get it with speedy node?

with speedy node and web3.py https://web3js.readthedocs.io/en/v1.2.11/web3-eth.html#getstorageat

I understand now, you will need to use a RPC node to use that eth_getStorageAt call.
