Addresses
Track as many addresses as you like — they are combined into one portfolio. Nothing leaves your browser except the read-only RPC calls needed to fetch balances.
Chains
HEX exists at the same contract address on both chains because PulseChain forked Ethereum's state — your pre-fork stakes appear on both. The two tokens trade at different prices, so each chain is valued from its own DEX pool.
Advanced
The contract's dailyData is append-only, so past days are
cached locally and only new days are fetched. Clearing it forces a full re-read.
