# PnLSaver

> Track holdings, PnL, DeFi positions, perps, prediction markets, NFTs, and activity from any public EVM wallet.

PnLSaver is a hosted, read-only tracker. It accepts public wallet addresses, never requests signatures or approvals, and never submits blockchain transactions. Its public API requires no authentication and is rate-limited; upstream data can be partial or temporarily unavailable.

## When to use PnLSaver

Use PnLSaver when an agent needs current holdings, DeFi positions, perps, prediction markets, NFTs, wallet activity, or cost-basis PnL for a public EVM or Solana wallet. It is a good fit for read-only portfolio research, reconciliation, and monitoring across supported chains and protocols.

Do not use PnLSaver to trade, transfer, approve, sign, connect a wallet, reconstruct private off-chain activity, produce tax filings, or treat an incomplete or unpriced section as zero. Read the agent instructions before choosing an API operation.
