Solana Swaps

Manage your Solana wallet: check balances and swap tokens using the Jupiter aggregator.

Environment Variables

These environment variables are pre-configured and available for use:

Variable	Description
SOLANA_KEYPAIR_PATH	Path to wallet keypair JSON file
JUPITER_API_KEY	Jupiter API key for authenticated requests (avoids platform fees, required for Token2022/pump.fun tokens)

Note: These are already set in the skill config. Just use $SOLANA_KEYPAIR_PATH and $JUPITER_API_KEY directly in commands.

Verify Setup

# Check wallet address
solana address --keypair "$SOLANA_KEYPAIR_PATH"

# Check Solana CLI config
solana config get

Balance Checking

Check SOL Balance

solana balance --keypair "$SOLANA_KEYPAIR_PATH"

List All Token Accounts

spl-token accounts --owner $(solana address --keypair "$SOLANA_KEYPAIR_PATH")

Check Specific Token Balance

spl-token balance <TOKEN_MINT_ADDRESS> --owner $(solana address --keypair "$SOLANA_KEYPAIR_PATH")

Common Token Mint Addresses

Token Swaps via Jupiter

CRITICAL: Always display swap details and wait for explicit user confirmation before executing any swap.

Step 1: Get Quote

Convert human-readable amounts to raw units:

• SOL: multiply by 1,000,000,000 (10^9)
• USDC/USDT: multiply by 1,000,000 (10^6)
• BONK: multiply by 100,000 (10^5)

# Example: Get quote for swapping 1 SOL to USDC
INPUT_MINT="So11111111111111111111111111111111111111112"
OUTPUT_MINT="EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
AMOUNT="1000000000"  # 1 SOL in lamports
SLIPPAGE_BPS="50"    # 0.5% slippage

# Get quote with API key authentication
curl -s -H "x-api-key: $JUPITER_API_KEY" \
  "https://api.jup.ag/swap/v1/quote?inputMint=${INPUT_MINT}&outputMint=${OUTPUT_MINT}&amount=${AMOUNT}&slippageBps=${SLIPPAGE_BPS}" | jq .

Step 2: Display Quote and Request Confirmation

Parse the quote response and display to user:

• Input: amount and token name
• Output: expected amount and token name
• Price impact percentage
• Slippage tolerance
• Minimum received (otherAmountThreshold)

IMPORTANT: Ask user "Do you want to proceed with this swap?" and wait for explicit confirmation ("yes", "proceed", "confirm") before continuing.

Step 3: Build Swap Transaction

After user confirms, request the swap transaction:

USER_PUBKEY=$(solana address --keypair "$SOLANA_KEYPAIR_PATH")

# Save quote response to file
QUOTE_FILE="/tmp/jupiter_quote.json"
curl -s -H "x-api-key: $JUPITER_API_KEY" \
  "https://api.jup.ag/swap/v1/quote?inputMint=${INPUT_MINT}&outputMint=${OUTPUT_MINT}&amount=${AMOUNT}&slippageBps=${SLIPPAGE_BPS}" > "$QUOTE_FILE"

# Request swap transaction
curl -s -X POST \
  -H "x-api-key: $JUPITER_API_KEY" \
  -H "Content-Type: application/json" \
  "https://api.jup.ag/swap/v1/swap" \
  -d "{
    \"quoteResponse\": $(cat $QUOTE_FILE),
    \"userPublicKey\": \"${USER_PUBKEY}\",
    \"dynamicComputeUnitLimit\": true,
    \"prioritizationFeeLamports\": {
      \"priorityLevelWithMaxLamports\": {
        \"maxLamports\": 5000000,
        \"priorityLevel\": \"high\"
      }
    }
  }" > /tmp/jupiter_swap.json

# Extract the swap transaction
SWAP_TX=$(cat /tmp/jupiter_swap.json | jq -r '.swapTransaction')

Step 4: Sign and Submit Transaction

Use the jupiter-swap.mjs script to sign and submit:

node "$(dirname "$0")/scripts/jupiter-swap.mjs" \
  --keypair "$SOLANA_KEYPAIR_PATH" \
  --transaction "$SWAP_TX"

The script will output the transaction signature and a Solscan link.

Safety Rules

1. ALWAYS display swap details and wait for user confirmation before executing
2. NEVER execute swaps automatically without explicit approval
3. ALWAYS check balance before attempting swaps to ensure sufficient funds
4. WARN users if price impact exceeds 1%
5. WARN users if slippage is set above 1% (100 bps)
6. NEVER log, display, or transmit private key contents

Error Handling

Error	Cause	Solution
"Insufficient balance"	Not enough input tokens	Check balance, reduce swap amount
"Slippage tolerance exceeded"	Price moved during swap	Get fresh quote, consider higher slippage
"Transaction expired"	Blockhash too old	Get fresh quote and retry immediately
"Account not found"	Missing token account	Token account will be created automatically
"Route not found"	No liquidity for pair	Try smaller amount or different token
"Platform fee not supported"	Token2022 tokens block platform fees	Use authenticated API with $JUPITER_API_KEY header

Retry Logic

If a swap fails due to network issues:

1. Wait 2-3 seconds
2. Get a fresh quote (prices may have changed)
3. Re-confirm with user showing new quote
4. Retry the swap

Example Interactions

Check Balance

User: "What's my SOL balance?"

1. Run: solana balance --keypair "$SOLANA_KEYPAIR_PATH"
2. Report: "Your wallet has X.XXX SOL"

Swap Tokens

User: "Swap 0.5 SOL for USDC"

1. Get wallet address
2. Fetch Jupiter quote for 0.5 SOL (500000000 lamports) -> USDC
3. Display quote details:
   • From: 0.5 SOL
   • To: ~XX.XX USDC (estimated)
   • Price Impact: X.XX%
   • Minimum Received: XX.XX USDC
4. Ask: "Do you want to proceed with this swap?"
5. Wait for confirmation
6. On "yes": Execute swap, report transaction link
7. On "no": Acknowledge cancellation

List All Tokens

User: "Show me all my tokens"

1. Run: spl-token accounts --owner $(solana address --keypair "$SOLANA_KEYPAIR_PATH")
2. Format and display token list with balances
