A standardized smart contract interface for restricted (scoped) approval of token IDs, enabling fine-grained operator permissions for CBC-1155, CBC-721, and similar token contracts.
A universal registry smart contract where any address (contract or regular account) can register which interface it supports and which smart contract is responsible for its implementation. This standard keeps backward compatibility with CBC-165.
A standard for modular smart contract systems (diamonds) that can be extended after deployment, supporting unlimited contract size and upgradeability via facets.
A standardized smart contract interface for approvals via signatures (CIP-712), enabling energyless approvals for CBC-20 tokens and similar standards.
Batched Meta Transactions for CBC-20 and compatible tokens.
Transfer With Authorization for CBC-20 and compatible tokens.
A standardized smart contract interface for tokenized vaults with a single underlying CBC-20 token, supporting deposit, withdrawal, and share accounting.
