Printr is a cross-chain token launchpad where a creator deploys a token and seeds initial liquidity in one transaction. The plugin quotes launch cost, builds unsigned creation calldata through Printr’s HTTP API, and submits the result with Base MCP send_calls. Chains: Base, Arbitrum, Optimism, Polygon, BSC, Avalanche, and Ethereum. Operations: launch quotes, token creation, deployment status checks, cross-chain launch setup, and initial-buy configuration.
Multi-chain launchpad. Printr uses CAIP chain identifiers in API payloads, then maps returned payloads back to Base MCP chain names for send_calls.

Try it

Launch
Launch a memecoin called Doge Supreme (DSUP) on Base
Quote
What would it cost to launch on Base and Arbitrum?
Status
Did my token deploy on every chain?

​
Pattern

The assistant calls /print/quote first, shows per-chain and combined launch cost, then calls /print only after confirmation and valid token metadata. The returned payload.to includes a CAIP chain prefix, payload.calldata is base64, and payload.value is decimal wei. The assistant strips the eip155:<chainId>: prefix from to, base64-decodes calldata to hex, converts value to hex, maps the chain ID to a Base MCP chain string, and submits send_calls.
