Vultisig SDK Skill (agent-first)

What this Skill is for

• Creating and managing self-custodial crypto vaults (Fast Vault for agents, Secure Vault for multi-device)
• Sending transactions across 36+ blockchains (Bitcoin, Ethereum, Solana, Cosmos, and more)
• Swapping tokens cross-chain via THORChain, MayaChain, 1inch, LiFi, KyberSwap
• Querying balances and gas fees across all supported chains
• Importing/exporting vault backups (.vult files)
• Importing existing wallets via BIP39 seedphrase
• Building automated strategies: DCA, rebalancing, conditional swaps, agent-to-agent payments

Default stack decisions

1. Fast Vault (2-of-2) for all agent use cases
   • Agent holds one key share, VultiServer holds the other
   • VultiServer auto-co-signs based on policy rules — no human in the loop
   • Use Secure Vault only when multi-device human approval is required
