The Weld service plans to issue cards issued by the payment giant Visa, connected to all major cryptocurrency trading platforms and popular wallets, as well as to Apple Pay/Google Pay. It’s assumed that at the time of payment, the bank will transfer the transaction to an overdraft, the Weld service will transfer the corresponding amount in cryptocurrency from the user's wallet to its corporate account on the same exchange.
The innovative architecture doesn’t require card top upping, allows to avoid high blockchain fees, and spends cryptocurrencies as easily as fiat money. Residents from developing countries will be able to use such cards.
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Contract name (Weld.Money) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
BEP20TokenImplementation._approve(address,address,uint256).owner (#526) shadows:
- Ownable.owner() (#147-149) (function)
Rename the local variables that shadow another component.

BEP20TokenImplementation.setBotProtector(address)._botProtector (#431) lacks a zero-check on :
- botProtector_ = _botProtector (#432)
Check that the address is not zero.
