It supports the initialization of wallets from BIP39 mnemonics, facilitates zero-fee transactions using Spark, BTKN, and LRC20 tokens, and handles the creation and payment of Lightning and Spark native invoices. The skill also enables L402 paywall payments, manages Layer 1 deposits, cooperative withdrawals, and message signing. It automatically kicks in whenever users engage in tasks related to Bitcoin or financial transactions involving Spark, BTKN, BTC L2, or L402.\u003c\/p\u003e\n\n\u003ch3\u003eWhat this skill does\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eInitializes a self-custodial Bitcoin wallet using BIP39 mnemonics.\u003c\/li\u003e\n    \u003cli\u003eFacilitates zero-fee Spark and BTKN\/LRC20 token transfers.\u003c\/li\u003e\n    \u003cli\u003eManages creation and payment of Lightning invoices and Spark native invoices.\u003c\/li\u003e\n    \u003cli\u003eProcesses L402 paywall payments.\u003c\/li\u003e\n    \u003cli\u003eHandles Layer 1 deposits and cooperative withdrawals.\u003c\/li\u003e\n    \u003cli\u003eSupports message signing for transaction verification.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho it is for\u003c\/h3\u003e\n\u003cp\u003eThis skill is intended for developers and teams utilizing AI coding agents like Claude Code, Cursor, and Codex, who require autonomous Bitcoin transactions on the Spark network.\u003c\/p\u003e\n\n\u003ch3\u003eUse cases\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eDeveloping an agent that autonomously sends or receives Bitcoin.\u003c\/li\u003e\n    \u003cli\u003eSetting up a non-custodial wallet for an AI model to conduct transactions.\u003c\/li\u003e\n    \u003cli\u003eEnabling an AI agent to purchase real-world goods or services with Bitcoin, such as eSIMs, gift cards, VPNs, and burner numbers via platforms like Bitrefill, nadanada, or Cryptorefills.\u003c\/li\u003e\n    \u003cli\u003eIntegrating paywall solutions using L402 standards for accessing API services from code.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical details\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eUtilizes the `@buildonspark\/spark-sdk` for implementing wallet capabilities.\u003c\/li\u003e\n    \u003cli\u003eSupports transaction and invoice management using Spark L2.\u003c\/li\u003e\n    \u003cli\u003eCompatible with various digital assets, including Spark, BTKN, and LRC20 tokens.\u003c\/li\u003e\n    \u003cli\u003eAllows for seamless integration within AI workflows for Bitcoin-related transactions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThis skill provides general workflow assistance and should not be construed as financial, legal, tax, or accounting advice.\u003c\/p\u003e\n\u003c!-- mcpcart:static-blocks:start --\u003e\n\u003chr\u003e\n\u003ch3\u003eSource \u0026amp; Licence\u003c\/h3\u003e\n\u003cp\u003eThis package is built on open-source work published by \u003cstrong\u003eechennells\u003c\/strong\u003e (\u003ca href=\"https:\/\/github.com\/echennells\/sparkbtcbot\" rel=\"nofollow noopener\" target=\"_blank\"\u003eechennells\/sparkbtcbot\u003c\/a\u003e) and distributed under \u003cstrong\u003eMIT\u003c\/strong\u003e.
