About PnLSaver: a read-only portfolio tracker.

Why the project exists

Public wallets are easy to inspect one chain or protocol at a time and surprisingly hard to understand as one economic portfolio. Receipt tokens, lending accounts, liquidity positions, perps, rewards, and linked smart wallets can all represent value that a simple token list misses or counts twice. PnLSaver exists to assemble those public facts into a coherent view for portfolio owners, researchers, analysts, and developers.

Portfolio tracking is deliberately read-only and uses public addresses. An optional wallet picker can share an address without requesting signatures or transactions. Merkl reward claims and Treasure Hunt recoveries require user review, fresh server verification, and explicit wallet transaction approval. CoW swaps require reviewed limits and explicit token approvals and order signing. PnLSaver never asks for seed phrases or private keys, takes custody, or signs automatically.

How PnLSaver approaches correctness

Current holdings and protocol state are loaded independently from historical enrichment so an explorer crawl cannot block the first useful portfolio view. Token amounts retain their integer units and decimals until valuation, protocol identities stay chain-specific, and dedicated position readers arbitrate with generic receipt-token output so the same economic asset appears once.

Missing prices, unavailable providers, incomplete history, and unsupported positions are not silently converted to zero. PnLSaver shows known subtotals and coverage limitations separately because an honest partial answer is more useful than a precise-looking total built from absent data.
