Connection facts
What support means in Fillfolio
Does a network page mean every token is priced?
No. Fillfolio can display supported public-address balances, but a reliable market value requires a recognized asset and an available price.
Can Fillfolio send blockchain transactions?
No. Wallet connections are observation-only and cannot sign, transfer, stake, or approve assets.

Institution, brokerage, exchange, and network names and marks belong to their respective holders. Their appearance describes technical compatibility and does not imply affiliation, sponsorship, or endorsement. Connection availability and coverage can change by region, institution, account type, or provider maintenance.
