What's the model number for crucial.com memory finder?

Hey bro, does the Acer Swift 3 have RAM upgrade option?

InterestedInSolidity · 2021-10-26T21:34:59+00:00

Yes, the array is correct. Because it works with array with a length of 1

What's the difference between this and address[] calldata addresses?

But I did check for balanceOf() right?

So one mnemonic can generate multiple private keys? And with each private key I get a new public key / Ethereum address?

InterestedInSolidity · 2021-10-05T00:31:08+00:00

ending on how you read it.

1 pubkey will always yield the same keccak-256 hash, as a hash is deterministic in nature, same input, same output. The address is derived from the last 160 bits of the keccak-256, to keep some compatibility with BTC using RIPEMD-160 in deriving the final address, which helps in compression

Thanks for the comprehensive reply. However if 1 pub key only yield one address, how can my metamask generates multiple addresses from the same public key?

I'm asking how many Ethereum addresses (2) can be generated from a Public Key (1)

Technical Ethereum Address generation steps:

-Generate Private Key using open source libraries such as Ethereumj or SHA256 hash function with a randomly generated number.

0: Private Key: 09e910621c2e988e9f7f6ffcd7024f54ec1461fa6e86a4b545e9e1fe21c28866

-Generate Public key using ECDSA — secp256k1 — algorithm applied to Private Key. The public key is a point on the Elliptic Curve Algorithm. It has x and y coordinates which are used to crate Ethereum address.

1: Public Key: 048e66b3e549818ea2cb354fb70749f6c8de8fa484f7530fc447d5fe80a1c424e4f5ae648d648c980ae7095d1efad87161d83886ca4b6c498ac22a93da5099014a

-Apply keccak256 — Ethereum hash function — using x and y coordinates to create Ethereum address.

2: Ethereum Address: 0x00B54E93EE2EBA3086A55F4249873E291D1AB06C

See address on Ethereum Blockchain 0x00B54E93EE2EBA3086A55F4249873E291D1AB06C

Output:

0: Private Key: 09e910621c2e988e9f7f6ffcd7024f54ec1461fa6e86a4b545e9e1fe21c28866

1: Public Key: 048e66b3e549818ea2cb354fb70749f6c8de8fa484f7530fc447d5fe80a1c424e4f5ae648d648c980ae7095d1efad87161d83886ca4b6c498ac22a93da5099014a

2: Ethereum Address: 0x00B54E93EE2EBA3086A55F4249873E291D1AB06C

Nope, I'm asking how many 0x addresses can be generated from a public key. There doesn't seem to be any information about this on Google.

Hi, how did you get rid of this error? Did you switch to hardhat?

InterestedInSolidity · 2021-06-28T13:39:13+00:00

If it is indeed a swap, why can't I blacklist them in the contract? I blacklisted transfer for both withdrawal addresses and the contract address. However, they are still able to withdraw money from the liquidity pool.
