CyberShares

• Source: src/CyberShares.sol
• Inherits: ERC20Upgradeable

Partly implemented. Several functions, including safeMint and certificateTokenURI, have their bodies commented out or return empty values. This page describes the intended shape; check the source before relying on it.

Purpose

CyberShares is an ERC-20 share token for a single security class that also carries certificate-formation logic: fungible shares can be formed into individual certificates and voided back into shares.

Functions

function mint(address to, uint256 amount) external onlyIssuanceManager;
function burn(address from, uint256 amount) external onlyIssuanceManager;
function voidToShares(uint256 certId) external;          // burn a certificate back to shares
function formCertificateFromShares(uint256 amount, CertificateDetails details) external;
function setGlobalRestrictionHook(address hookAddress) external onlyIssuanceManager;
function setTransferable(bool _transferable) external onlyIssuanceManager;
function setCertThreshold(uint256 _threshold) external onlyIssuanceManager;
function decimals() public view returns (uint8);
function certThreshold() public view returns (uint256);
function sharesUri() public view returns (string);

It also exposes certificate* helpers (certificateOwnerOf, certificateApprove, certificateTransferFrom and others) that mirror an ERC-721 surface for the formed certificates.

Events

SharesMinted, SharesBurned, CertificateFormed, SharesFromCertificate, SharesFromVoidedCertificate, GlobalRestrictionHookSet, TransferableSet, CertThresholdSet, plus Certificate* events.

Share counts

CyberShares keeps no authorized, outstanding or reserved counters. The register of holders is the set of Ledger Entry Tokens (LETs) on the company's LedgerEntryToken contracts, and share counts are read from there.
