BEP-20 Compatibility

The BEP20 specification defines a list of API functions (and relevant events) that each token contract is expected to implement (and emit). The failure to meet these requirements means the token contract cannot be considered to be BEP20-compliant. In this section, we examine the list of API functions defined by the ERC20 specification and validate whether there exist any inconsistency or incompatibility in the implementation or the inherent business logic of the audited contract(s)

	Expected Functionality	Description according to the BEP20 Standard	Compatible
name	is declared as a public view function ✓	Returns the name of the token.	✓
symbol	Is declared as a public view function	Returns the symbol of the token.	✓
decimals	declared as a public view function	Returns the number of decimals used to get its user representation	✓
totalSupply	Is declared as a public view function	Returns the amount of tokens in existence.	✓
balanceOf	Is declared as a public view function	Returns the amount of tokens owned by account.	✓
allowance	allowance() Is declared as a public view function	Returns the remaining number of tokens that spender will be allowed to spend on behalf of owner through transferFrom.	✓
transfer	transfer() is declared as a public function	Moves amount tokens from the caller’s account to recipient. Returns a boolean value indicating whether the operation succeeded. Emits a Transfer event.	✓
transferFrom	Is declared as a public function ✓ Returns a boolean value which accurately reflects the token transfer status ✓ Reverts if the spender does not have enough token allowances to spend ✓ Updates the spender’s token allowances when tokens are transferred successfully ✓ Reverts if the from address does not have enough tokens to spend Allows zero amount transfers ✓ Emits Transfer() event when tokens are transferred successfully (include 0 amount transfers) ✓ Reverts while transferring from zero address ✓ Reverts while transferring to zero address ✓	Moves amount tokens from sender to recipient using the allowance mechanism. amount is then deducted from the caller’s allowance. Returns a boolean value indicating whether the operation succeeded. Emits a Transfer event.	✓
approve	Is declared as a public function ✓ Returns a boolean value that accurately reflects the token approval status ✓ Emits Approval() event when tokens are approved successfully ✓ Reverts while approving to zero address ✓	Sets amount as the allowance of spender over the caller’s tokens. Returns a boolean value indicating whether the operation succeeded.	✓
Transfer Event	Is emitted when tokens are transferred, including zero value transfers Is emitted with the from address set to address(0) when new tokens are generated ✓	Emitted when value tokens are moved from one account (from) to another (to). Note that value may be zero	✓
Approval Event	Is emitted on any successful call to approve ✓	Emitted when the allowance of a spender for an owner is set by a call to approve. value is the new allowance.	✓
