Technical Deep Dive

How PnL is Calculated

A transparent look at how we process transactions, track cost basis, and compute accurate profit and loss for your Solana portfolio.

1High-Level Flow

Fetch Raw Transactions

We pull all historical transactions for your wallet from the Solana blockchain via Helius RPC.

Parse & Classify Transactions

Each transaction is analyzed to determine its type: Swap, Transfer, Liquidity, Create, or Burn.

Extract Token Changes & Fees

For each transaction, we extract token balance changes and identify all fees paid.

Update Token Info

Token-level metrics are updated: balance, cost basis, realized PnL, and transaction counts.

Aggregate to Portfolio

Token-level data is aggregated into portfolio-wide metrics with current price valuations.

2Transaction Classification

Each transaction is classified based on program interactions and balance changes:

SWAP

Exchange one token for another through a DEX (Jupiter, Raydium, Pump.fun, etc.)

• Detected via DEX program IDs

• Extracts input/output amounts

• Updates buy/sell metrics

TRANSFER

Move tokens between wallets (including your own wallets)

• Preserves cost basis through transfers

• Tracks pending cost basis for exports

• No realized PnL on transfers

LIQUIDITY

Add or remove liquidity from AMM pools

• Tracks ADD and REMOVE operations

• Calculates liquidity PnL separately

• Handles LP token issuance

CREATEBURN

Token creation (bonding curves) and token burns

• CREATE: Initial token purchase

• BURN: Token destruction

• Affects cost basis accordingly

3Fee Extraction

We identify and track all fees to ensure accurate cost basis and PnL:

Transaction Fees

Base Solana transaction fee + priority fee paid to validators

Protocol Fees

Fees paid to DEXs, trading bots (Photon, Axiom), and platforms

MEV Tips

Jito bundle tips and other MEV-related payments

Why fees matter: Most portfolio trackers ignore fees entirely. A $100 buy with $5 in fees means your actual cost basis is $105, not $100. This 5% difference compounds across hundreds of trades, leading to significantly incorrect PnL.

4PnL Calculation

Realized PnL is calculated when you sell tokens. We use FIFO (First In, First Out) cost basis:

// On each SELL transaction:

avgBuyCost = remainingCost / tokenBalance

costBasisSold = avgBuyCost × tokensSold

saleProceeds = actualAmountReceived

realizedPnL = saleProceeds - costBasisSold

Example: Profitable Trade

Buy 100 tokens for 1 SOL → Sell 50 tokens for 0.8 SOL
Cost basis: 0.5 SOL → Proceeds: 0.8 SOL
Realized PnL: +0.3 SOL (+60%)

Example: Loss Trade

Buy 100 tokens for 1 SOL → Sell 50 tokens for 0.2 SOL
Cost basis: 0.5 SOL → Proceeds: 0.2 SOL
Realized PnL: -0.3 SOL (-60%)

5Portfolio Aggregation

Individual token metrics are aggregated to create portfolio-wide statistics:

Metric	Calculation
Total Realized PnL	Σ token.realizedPnL
Total Unrealized PnL	Σ token.unrealizedPnL
Win Rate	tokensWithProfit / totalTokens
Total Fees	Σ token.fees (tx + protocol + MEV)
2x / 10x / 100x Count	count(token.pnlPct >= threshold)
Rug Count	count(token.pnlPct <= -95%)
