Solana Easy Swap

Swap any Solana token from chat. Say "swap 1 SOL for USDC" and it handles everything — quoting, signing, sending, confirming. No API keys, no wallet extensions, no setup beyond a keypair. Powered by Jupiter.

Setup

First run: Install dependencies (automatic if install spec is supported, otherwise manual):

cd {baseDir} && npm install --production

Required env var:

• SOLANA_KEYPAIR_PATH — path to a Solana keypair JSON file (standard solana-keygen format). This skill reads your keypair to sign transactions. Only use with a keypair you trust this skill to access.

Optional env vars:

• SOLANA_RPC_URL — custom RPC endpoint (default: https://api.mainnet-beta.solana.com)
• OSS_DEFAULT_SLIPPAGE_BPS — default slippage in basis points (default: 100 = 1%)
• OSS_PRIORITY_FEE_FLOOR — minimum priority fee in lamports (default: 50000)

No API keys required. Jupiter is used unauthenticated.

Common Token Mints

Token	Mint
SOL (wrapped)	So11111111111111111111111111111111111111112
USDC	EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v
USDT	Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB

For other tokens, ask the user for the mint address.

Flow

1. Prepare

node {baseDir}/scripts/swap.mjs prepare \
  --from So11111111111111111111111111111111111111112 \
  --to EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v \
  --amount 1000000000 \
  --slippage 100

Returns JSON:

{
  "prepareId": "abc123",
  "expectedOut": "150230000",
  "minOut": "148727700",
  "priceImpact": "0.01",
  "expiresAt": "2025-02-13T20:00:00Z",
  "summary": {
    "from": "1 SOL",
    "to": "~150.23 USDC",
    "minReceived": "148.73 USDC",
    "slippage": "1%",
    "priceImpact": "0.01%",
    "destination": "owner"
  }
}

Always show the summary to the user and wait for confirmation before executing.

If priceImpact > 1%, warn the user explicitly.

2. Execute

After user confirms:

node {baseDir}/scripts/swap.mjs execute --prepareId abc123

Returns JSON:

{
  "signature": "5UzV...",
  "submittedAt": "2025-02-13T19:58:12Z"
}

3. Status (poll until confirmed)

node {baseDir}/scripts/swap.mjs status --signature 5UzV...

Returns JSON:

{
  "state": "confirmed",
  "slot": 123456789,
  "confirmationStatus": "finalized"
}

States: submitted → confirmed | failed | expired | unknown

4. Receipt

node {baseDir}/scripts/swap.mjs receipt --signature 5UzV...

Returns JSON with actual amounts swapped, fees, and a Solscan link.

Error Handling

All commands return JSON with error field on failure:

{
  "error": {
    "code": "INSUFFICIENT_SOL",
    "message": "Not enough SOL for fees. Have 0.001, need ~0.006",
    "retryable": false
  }
}

Error codes and retry guidance:

Code	Retry?	Action
INVALID_INPUT	No	Fix the input
INSUFFICIENT_SOL	No	Tell user they need more SOL
KEYPAIR_NOT_FOUND	No	Check SOLANA_KEYPAIR_PATH is set
KEYPAIR_INVALID	No	Check keypair file format
PREPARE_EXPIRED	Yes	Run prepare again, re-confirm with user
PREPARE_ALREADY_EXECUTED	No	This swap was already sent
BACKEND_UNAVAILABLE	Yes	Wait 3s, retry prepare up to 2x
BACKEND_QUOTE_FAILED	No	No route — tell user (bad pair or no liquidity)
TX_EXPIRED	Yes	Run prepare again, re-confirm with user
TX_BROADCAST_FAILED	Yes	Retry execute once (if not expired)
TX_FAILED_ONCHAIN	No	Swap failed (e.g., slippage). Do NOT retry.
RPC_UNAVAILABLE	Yes	Wait 3s, retry up to 2x

Agent Guidelines

1. Always confirm before executing. Show the user the summary from prepare and wait for explicit "yes" / "go" / "confirm".
2. Never auto-retry failed onchain transactions. If TX_FAILED_ONCHAIN, the tx landed and failed — retrying sends a new tx.
3. Re-confirm on re-prepare. If you need to prepare again (expired quote), show the new summary — prices may have changed.
4. Handle amounts in base units. SOL = 9 decimals (1 SOL = 1000000000), USDC = 6 decimals (1 USDC = 1000000).
5. Ask for mint addresses if the user mentions a token you don't recognize. Don't guess.
6. Report the Solscan link after confirmation: https://solscan.io/tx/{signature}

Security

• This skill signs transactions using the configured keypair. It does NOT create, import, or manage keys.
• Keypair material is never logged, echoed, or included in any output.
• Third-party destinations require explicit --allowThirdParty flag.
• All swaps enforce slippage protection via minOut.
• Prepared swaps expire after 120 seconds by default.

Limitations (v1)

• Jupiter unauthenticated API — Token2022 and pump.fun tokens may not work.
• No best-price routing — takes whatever Jupiter returns.
• Receipt amounts are best-effort (derived from pre/post balance diffs).
• Solana mainnet only.
