allTokens

AllTokens is a term used in blockchain software to describe functionality that retrieves or enumerates all token holdings associated with a given address. The concept spans fungible tokens such as ERC-20s and non-fungible tokens such as ERC-721s or ERC-1155s, and it can apply across different networks. There is no formal standard named “allTokens”; rather, various wallets, explorers, and development kits implement similar capabilities under different names, such as getAllTokens, listTokens, or tokenBalances.

Functionality typically involves aggregating on-chain and sometimes off-chain data to present a unified view of an address’s token assets. For fungible tokens, implementations may query balances directly or use token registries and indexers. For non-fungible tokens, they may retrieve NFT balances and enumerate token identifiers owned by the address using standard methods like balanceOf and tokenOfOwnerByIndex, or rely on blockchain indexers that track token ownership. The resulting data set often includes token contract addresses, symbols, decimals, balances, token types, and metadata pointers.

Common use cases include portfolio tracking, asset management, and tax reporting, where users or applications want a comprehensive list of assets held. Implementations vary by provider and may include features such as pagination, filtering by token standard, multi-chain support, and caching. Limitations arise from data availability and freshness, indexing latency, and privacy or rate limits when querying multiple contracts or networks.
