I am pretty new to Cairo and I am thinking of building a dApp that takes web3 wallet signatures and validate it in Cairo-based contract on Starknet. When using web3.js, I can sign a message like this: web3.eth.accounts.sign('Some data', '0x4c0883a69102937d6231471b5dbb6204fe5129617082792ae468d01a3f…

have you tried this? @martriay cairo-examples/secp at master · starkware-libs/cairo-examples · GitHub

I haven’t, I didn’t know that was released!

Note that OpenZeppelin Contracts for Cairo v0.2.0 comes with an EthAccount contract!

Hi @0xwalid , this is 2025 and I am having the same issue as you. How did you solve this problem eventually? If you did, do you have a better way to do it now. I need to verify a signature on my smar contract. thanks

Is it possible to use verify_ecdsa_signature in cairo to verify a web3.js/wallet ecdsa signature?

🙏 Help and Support Support

It’s not, that’s the StarkKey’s signing algorithm. Check Support Web3 wallets in StarkNet
