Valuation

Valuation module measures the value of a DeFi position by using tokenization with external oracles.

Tokenization

Tokenization turns a DeFi position into a token (i.e., ERC1155) so that it can be easily valuated and collateralized.

Write Methods

setCustomTokenFactor

function setCustomTokenFactor(uint256 _tokenTypeOrId, uint _collateralFactor, uint _debtFactor)

Set token collateral/debt custom factor.

  • _tokenTypeOrId: If erc20 asset, token id. If factorial asset, 24bit tokenType.

  • _collateralFactor: The collateral factor of token/wrapping sepc.

  • _debtFactor: The debt factor of token/wrapping spec.

wrap

function wrap(uint24 _wrapperType, bytes calldata _param)

Wrap token/assets to ERC1155 factorial token.

  • _wrapperType: The 24-bit wrapper type. Not underlying asset type.

  • _param: The parameter using specific wrapping contract.

unwrap

function unwrap(uint _tokenId, uint _amount)

Unwrap token/assets from ERC1155 factorial token.

  • _tokenId: The ERC1155 factorial token id.

  • _amount: The amount of token to unwrap. If NFT token, it should be 1.

View Methods

getValue

function getValue(uint _tokenId, uint _amount) external view override returns (uint)

Return value of token by id and amount.

  • _tokenId: The token ID to be valued.

  • _amount: The amount of token to be valued. If NFT token, it should be 1.

getValueAsCollateral

function getValueAsCollateral(address _lendingProtocol, uint _tokenId, uint _amount) external view returns (uint)

Return token value as collateral. For debt token wrapper.

  • _lendingProtocol: The lending protocol address. This is for custom factor.

  • _tokenId: The token ID to be valued.

  • _amount: The amount of token to be valued. If NFT token, it should be 1.

getValueAsDebt

function getValueAsDebt(address _lendingProtocol, uint _tokenId, uint _amount) external view returns (uint)

Return token value as debt. For debt token wrapper.

  • _lendingProtocol: The lending protocol address. This is for custom factor.

  • _tokenId: The token ID to be valued.

  • _amount: The amount of token to be valued. If NFT token, it should be 1.
