21Shares filed an S-1 to launch a passive 21Shares SEI ETF tracking the CF SEI-Dollar index.

Coinbase Custody is named custodian.

The fund may reflect SEI staking rewards only if legal and tax risks are cleared and regulators permit.

SEC scrutiny is expected after prior ETH staking delays.

SEI rose 3.33% to $0.30 (market cap ~$1.82B). Technicals show support near $0.29.

Investors should manage risk.
