Networks
The eighteen chains the Wallet reads, what is available on each one, and why coverage is not identical everywhere.
The Wallet reads addresses on eighteen networks. Coverage is not the same on all of them, and this page says exactly what you get where.
The website only ever reads. Everything that requires a key — sending, signing, connecting to a site — happens in SWOP, which supports the same set of networks.
The networks
Ethereum, Bitcoin, Solana, BNB Chain, Base, Arbitrum, Optimism, Polygon, Avalanche, Gnosis, Celo, Linea, Scroll, Blast, Mantle, Cronos, Moonbeam, Fantom.
They fall into three families, and the family determines what an address looks like and how it is read:
EVM — fifteen of them. One address format, 0x followed by 40 hexadecimal characters, and the same address is valid on every one. An address you use on Ethereum exists on Base, on Arbitrum, on all of them, holding different balances on each.
Bitcoin — its own address formats and its own model. There are no tokens; there is BTC.
Solana — its own address format, its own tokens.
What is available on each
Three levels of coverage, because the data sources differ:
Balances, tokens and history
Ethereum, Polygon, Arbitrum, Linea, Blast, Mantle, Base, Optimism, BNB Chain, Avalanche, Gnosis, Celo, Scroll, Bitcoin.
Everything works on these: current holdings, the full movement history, cost basis and realized P&L where the history is complete.
Balances and tokens, no history
Solana, Cronos, Moonbeam, Fantom.
Holdings and their value appear and count towards your totals. Movements do not, so no cost basis is built from them, and nothing on these networks contributes to realized P&L.
This is a provider limitation rather than a decision. Solana's history in particular is a known gap and is expected to close.
Native coin only
Mantle, Cronos, Moonbeam and Fantom are not covered by the portfolio provider, so their native balance is read directly from a public node of the chain. MNT, CRO, GLMR and FTM appear; tokens on those chains may not.
Ethereum
Ethereum has the most complete coverage on the platform: every transfer, every fee, and purchase prices rebuilt transfer by transfer. It is where the platform started, and the numbers on Ethereum can be trusted furthest.
Moving between networks
A bridge transfer is not a purchase or a sale. Sending USDC from Ethereum to Base leaves one chain and arrives on another, and nothing was bought, sold or realized.
The platform detects these and excludes them from trade reconstruction. Cost basis covers the rule and the cases where detection is hard.
The same applies to your own addresses. Moving between two wallets you both hold is not a trade, and it is excluded when both are tracked. Which is a reason to add every address you own rather than only the ones with balances worth watching.
When a network does not answer
If one network is temporarily unavailable, your holdings there keep their last reading instead of dropping to zero, so your portfolio does not appear to lose money because a network was slow.
Adding a network
Networks are added when a data source covers them well enough for the numbers to hold. The limit is not the chain, it is whether history can be read completely enough to build cost basis from.
A network where only part of the history is available would produce a P&L figure that looks usable and is not, which is the outcome the platform treats as worse than showing nothing.
