On April 12, the tokenized fund management protocol Alvara Protocol announced that the Ethereum Foundation officially recognized the ERC-7621 proposal and merged it into a draft standard. The ERC-7621 standard allows for the creation of tokenized funds backed by multiple assets on the blockchain. Anyone can deploy BTS (basket tokens) containing multiple ERC-20 tokens, bringing unprecedented flexibility to fund management. The key features of BTS include: 1. Transferable BTS tokens and management rights; 2. Fungible liquidity provider tokens (BTS LP), representing the holder’s share in the fund; 3. Flexible investment portfolio The adjustment function allows managers to modify token types and weights, and supports automatic or manual rebalancing. ERC-7621 improves many problems existing in traditional fund management by increasing transparency and decentralization, simplifying management processes, improving accessibility of investment opportunities.
