Write

1. approve
   • See IERC20-approve. NOTE: If amount is the maximum uint256, the allowance is not updated on transferFrom. This is semantically equivalent to an infinite approval. Requirements: - spender cannot be the zero address.
2. burn
   • Allows the authorized bridges (checked via the factory) to burn tokens on withdrawals Required user: bridge
3. decreaseAllowance
   • Atomically decreases the allowance granted to spender by the caller. This is an alternative to approve that can be used as a mitigation for problems described in IERC20-approve. Emits an Approval event indicating the updated allowance. Requirements: - spender cannot be the zero address. - spender must have allowance for the caller of at least subtractedValue.
4. increaseAllowance
   • Atomically increases the allowance granted to spender by the caller. This is an alternative to approve that can be used as a mitigation for problems described in IERC20-approve. Emits an Approval event indicating the updated allowance. Requirements: - spender cannot be the zero address.
5. initialize
   • Initializes the token with factory variabls Required user: factory
6. mint
   • Allows the authorized bridges (checked via the factory) to mint tokens on deposits Required user: bridge
7. transfer
   • See IERC20-transfer. Requirements: - to cannot be the zero address. - the caller must have a balance of at least amount.
8. transferFrom
   • See IERC20-transferFrom. Emits an Approval event indicating the updated allowance. This is not required by the EIP. See the note at the beginning of ERC20. NOTE: Does not update the allowance if the current allowance is the maximum uint256. Requirements: - from and to cannot be the zero address. - from must have a balance of at least amount. - the caller must have allowance for from's tokens of at least amount.
