1/ @PhotonsHedge is revolutionizing the financial landscape by tokenizing the data of assets, thereby unlocking the true potential of the data economy. This will help enhance transparency in trading and provides new opportunities to investors.

2/ Asset data tokenization involves creating secured digital tokens on a distributed ledger. A 2020 study by a German FinTech firm #Cashlink and custody provider @Finoa_io, stated that moving securities on blockchains could save $17B - $24B yearly in global trade running costs.
@Finoa_io 3/ By digitally representing physical assets on distributed ledgers, @PhotonsHedge adds liquidity to assets. Liquidity can be provided when assets such as @oceanprotocol or securitized data, are staked. This significantly depicts how asset data is tokenized and democratized.

1/ Solidity is indispensable for developers building #decentralized applicationsโผ๏ธ This article will discuss how the delegatecall in #Solidity can introduce vulnerabilities in #smartcontracts and highlight measures for preventing issues associated with using it in your code.๐ก

In #Solidity, call and delegatecall are low-level interfaces for interacting with contracts. Triggering the call function in a contract causes the code at that address to execute in the context of the target contract.

3/ #delegatecall works differently because execution occurs in the context (programming environment) of the caller contract. For example, a delegatecall from contract A to contract B would modify contract Bโs storage using functions in contract A. #smartcontracts

First, we're excited to announce our audit of @exiledracers' smart contract - in the lead up to their mint on May 31. โ
Our work together helped identify this ecosystem-wide issue of a weak pseudo-random number generator (PRNG) + Signature frontrunning/replay

The weak PRNG issue is way too common in the #gaming ecosystem. If you are not using @chainlink VRF and want to generate a PRNG, never use msg.sender or a controlled address in the generation.
