ShareDebtToken
ShareDebtToken
ERC20 compatible token represennting debt position in Silo
It implements reversed approvals (ERC20R) and checks solvency of receiver on transfer. It is assumed that there is no vector attack on taking somone else's debt becasue we don't see economical reason why one would do such thing. For that reason anyone can transfer owner's token to any receiver as long as receiving wallet approves the transfer. In other words, anyone can take someone else's debt without asking.

function decimals() external view returns (uint8)
Returns the number of decimals used to get its user representation. For example, if
decimals equals 2, a balance of 505 tokens should be displayed to a user as 5.05 (505 / 10 ** 2). Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the value {ERC20} uses, unless this function is overridden; NOTE: This information is only used for display purposes: it in no way affects any of the arithmetic of the contract, including {IERC20-balanceOf} and {IERC20-transfer}.Name | Type | Description |

function decreaseAllowance(address spender, uint256 subtractedValue) external nonpayable returns (bool)
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.

function setReceiveApproval(address owner, uint256 _amount) external nonpayable returns (bool)
Sets
_amount as the allowance of spender over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 OR use increase/decrease approval method instead.
