Other values may appear later; the swap path is the same as long as the token has a tradeable pool. +- `timestamp` — milliseconds since epoch (note: more than 13 digits in the sample because the API uses a high-precision counter; treat as monotonically decreasing in array order). +- `deployer.xUsername`, `tweetUrl`, `websiteUrl` — optional context to surface to the user before they buy. + +The API returns roughly 50 launches per call.

Use the same thresholds as other DEX plugins, but be more vocal about elevated values for Bankr launches specifically: + +| Tolerance | Level | Action | +| --- | --- | --- | +| ≤ 1% | Normal | Often **not enough** for fresh launches — the swap may revert. | +| > 1% and ≤ 5% | Elevated | Reasonable default for newly launched tokens. Mention the value. | +| > 5% and ≤ 20% | High | Warn that the trade may fill significantly below quote and is a likely sandwich target. Require explicit confirmation. | +| > 20% | Very high | Strongly warn; do not submit without the user re-confirming the exact number. | + +If the user did not specify a slippage, default to `0.05` (5%) for Bankr launches and call that out before submitting. + +--- + +## Safety Notes + +- **Symbol collisions.** Multiple launches can share the same symbol (the sample feed contains three `simstudioai` launches with different symbols and addresses). Always disambiguate by `tokenAddress` and confirm with the user before swapping. +- **No endorsement.** The Bankr feed is unfiltered. The Base MCP and this plugin do not vet, endorse, or audit listed tokens — many are low-liquidity, short-lived, or meme tokens. Mention this once before the first buy of a session. +- **Adversarial metadata.** Token names, symbols, deployer handles, and website URLs are user-supplied and can be misleading or impersonate legitimate projects. Don't follow links from the feed; surface them to the user for context only. +- **Address case.** Pass `tokenAddress` to `swap` verbatim — lowercased addresses from the API work fine; do not re-checksum or modify them. +- **Buy size.** Do not propose a default buy amount. The user must specify the amount. + +--- + +## Notes + +- Native ETH address: `0x0000000000000000000000000000000000000000` +- USDC on Base: `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` +- WETH on Base: `0x4200000000000000000000000000000000000006` +- Token amounts are base units: USDC = 1e6 per token, ETH/WETH = 1e18 per token. Base units for arbitrary launched tokens depend on the token's `decimals()` — most Doppler launches use 18, but if a swap returns a quote that's wildly off, fetch the token's decimals from the Base MCP portfolio or via an `eth_call` before retrying. +- Always use `chain: "base"` (string) with `swap`, not the numeric chainId. +- The feed updates frequently (new launches every few minutes during peak hours).

Refresh with `login_refresh` once the JWT expires. + +## Troubleshooting + +The Base MCP wallet is a Coinbase Smart Wallet (contract account, not a plain EOA). The SIWE signing path has a few sharp edges — these are the failure modes we've observed. + +### 1. `Invalid SIWE signature` (401) on `login_complete` + +The most common cause: the signature returned by Base MCP `sign` is an **ERC-6492 wrapped** signature (used for counterfactual or contract-deployment-attached signing), and the Virtuals verifier expects a plain **ERC-1271** signature. + +You can recognize ERC-6492 wrapped signatures by: +- Length: thousands of hex characters (the inner ERC-1271 signature is much shorter). +- They end with the magic suffix `6492649264926492649264926492649264926492649264926492649264926492`. + +**Recovery:** restart the auth flow from `login_start`. Subsequent approvals from the same wallet can produce a plain ERC-1271 signature that Virtuals accepts; the wrapping behavior isn't deterministic from one approval to the next. If it keeps returning ERC-6492 wrapped signatures, ask the user to confirm via the same approval URL again — repeated retries typically resolve to a plain ERC-1271 signature within a few attempts. + +Do **not** try to unwrap the ERC-6492 envelope manually and submit just the inner bytes — Virtuals rejects that too, because the inner Coinbase Smart Wallet signature format isn't a vanilla ERC-1271 `(r, s, v)` either. + +### 2. Address case mismatch + +Pass the wallet address to `login_start` exactly as returned by Base MCP `get_wallets`. The returned address is lowercase, which is fine — Virtuals normalises it. But when calling `login_complete`, **the `message` you pass must be the verbatim string returned by `login_start`** (which uses the EIP-55 checksummed address). Do not lowercase or otherwise reformat the message. A single character change in casing inside the message hashes to a different value than what was signed and the server will return `Invalid SIWE signature`. + +Verified working pattern: +- `login_start` input: lowercase address (e.g. `0xca8f1eb...`) → fine +- `login_complete` `message`: verbatim string from the `login_start` response (contains the checksummed `0xCa8F1eB...`) → required + +### 3. Nonce expired + +SIWE nonces expire 30 minutes after `login_start`. If the user took a long time to approve, or you waited and tried again later, `login_complete` will fail. Restart from `login_start` to get a fresh nonce — do not reuse an old one. + +### 4. Message whitespace / newlines + +The SIWE `message` field in `sign` (as `data.message`) and the `message` field in `login_complete` must be byte-identical to what `login_start` returned. JSON-escape `\n` correctly when embedding in the `sign` tool's `data` payload. When passing the message to `login_complete`, use real newlines (the same characters the JSON `\n` escapes decoded to). Any mismatch — extra trailing whitespace, CRLF vs LF, etc. — breaks the hash and yields `Invalid SIWE signature`. + +### 5. Wallet not deployed on Base + +ERC-1271 verification calls the wallet contract on Base. If the Coinbase Smart Wallet has never been activated on Base mainnet, the contract isn't deployed and verification will fail even with a structurally correct signature. Confirm deployment by checking `eth_getCode` for the address on Base mainnet — non-empty bytecode means it's deployed. Most Base MCP users will already have a deployed wallet; if not, ask the user to perform a no-op transaction first (any Base transaction will deploy the wallet). + +### 6. Token expired mid-session + +JWTs returned by `login_complete` expire after about an hour. When a Virtuals tool returns a 401, call `login_refresh` with the stored `refreshToken` to get a new access token; only re-run the full SIWE flow if the refresh token is also rejected. + +## Example Prompts + +``` +Log me into Virtuals +``` +1. `get_wallets` (Base MCP) → `baseAccount.address`. +2. `login_start` (Virtuals) with that address → SIWE message. +3. `sign` (Base MCP) with `type: "personal_sign"`, `data: { message }` → approval URL. +4.
