Connection guide
How to connect Base
- 1
Open blockchain wallets
Open Accounts & imports and choose Blockchain wallets. Give the Base connection a label you can recognize.
- 2
Choose the input and network
Enter the EVM public address, then include Base in the selected networks. A shared 0x address format does not establish which network holds your assets.
- 3
Preview coverage
Use Preview wallet and check ETH balances, recognized assets and warnings. Compare the selected network and address with your own records. Resolve a pricing error before saving.
- 4
Save and review
Use Add wallet after reviewing the preview. Check the saved connection and its last sync time. The tracking permission remains read-only; saving and later refreshes use the applicable monthly wallet credits.
Check timestamps and update coverage
Check the last sync time for your Base connection and the price context for each recognized asset. A wallet refresh retrieves supported balances; a spreadsheet sync or AI read exports stored data. A balance and its market price can have different observation times.
Resolve connection and coverage issues
A holding or value is missing
Read the coverage warning. Unmatched tokens remain excluded until an exact supported identity and price exist. A missing native-asset quote can prevent a priced import. Fillfolio keeps saved holdings unchanged when pricing fails.
A refresh cannot proceed
Review remaining wallet credits, address/network-pair limits and the connection's notice. Remove an unwanted connection from Accounts & imports if you need capacity; removing it does not transfer or spend its assets.
Fictional example
Base: balance, price and cost basis
- Fictional balance
- 2 ETH
- Fictional unit price
- USD 100
- Illustrative market value
- USD 200
- Cost basis
- Unavailable
- Personal P/L
- Unavailable
These quantities and prices are fictional, not market quotes or a live wallet. An available market value does not establish purchase cost or personal return. A real import requires a verified asset and price.

Questions
Before you connect
Which plan includes Base tracking?
PRO, ULTRA and HYPER include supported public-address wallet tracking. Address, network-pair and monthly refresh-credit limits vary by plan. Each recognized holding still needs the supported input and pricing coverage.
How do I track Base?
Open Blockchain wallets in Accounts & imports, choose Base and enter a supported public address. Review recognized balances, asset coverage and pricing before saving. No signing permission or private key is needed.
Which assets can Base tracking import?
Native assets require exact identities and verified prices. Fillfolio excludes unmatched tokens with a coverage warning; a missing native price can prevent a priced import. Failed pricing leaves saved holdings unchanged. No private key or signing access is requested.
How do missing exchange rates and partial wallet totals differ?
A missing exchange rate prevents a required currency conversion, so the affected converted value and dependent total are unavailable. A wallet may instead have balances excluded because their asset identity or price cannot be verified. In that case, totals include available priced holdings only and show an incomplete-coverage warning. Unsupported tokens stay excluded until an exact supported match is available.
Can Fillfolio transact through Base?
No. Fillfolio is read-only portfolio tracking software. It cannot trade, transfer, approve, sign, or move money.
