SafeERC20.sol
SafeERC20.sol is a Solidity library that provides wrappers around ERC20 operations that throw on failure. It supports tokens that return no value and instead revert or throw on failure, assuming non-reverting calls to be successful. This library is designed to make ERC20 token transfers safer and easier to work with in smart contracts.
A library that provides safe wrappers around the common ERC20 token operations.
safeTransfer(IERC20 token, address to, uint256 value) Safely transfers tokens from the contract to another address.
- token
IERC20: The token to be transferred. - to
address: The address to receive the tokens. - value
uint256: The number of tokens to be transferred.
safeTransferFrom(IERC20 token, address from, address to, uint256 value) Safely transfers tokens from one address to another.
- token
IERC20: The token to be transferred. - from
address: The address to send the tokens from. - to
address: The address to receive the tokens. - value
uint256: The number of tokens to be transferred.
safeApprove(IERC20 token, address spender, uint256 value) Safely approves another address to spend tokens on behalf of the contract.
- token
IERC20: The token to be approved. - spender
address: The address which will spend the tokens. - value
uint256: The number of tokens to be approved for spending.
safeIncreaseAllowance(IERC20 token, address spender, uint256 value) Safely increases the allowance of another address to spend tokens on behalf of the contract.
- token
IERC20: The token to be approved. - spender
address: The address which will spend the tokens. - value
uint256: The number of tokens to increase the allowance by.
safeDecreaseAllowance(IERC20 token, address spender, uint256 value) Safely decreases the allowance of another address to spend tokens on behalf of the contract.
- token
IERC20: The token to be approved. - spender
address: The address which will spend the tokens. - value
uint256: The number of tokens to decrease the allowance by.
