vultisig
This skill lets agents create and manage self-custodial crypto vaults, send transactions, swap tokens, and import/export encrypted backups via the `@vultisig/sdk`. Examples run shell commands (`npm install -g @vultisig/sdk`, `vsig ...`), handle secrets (`mnemonic`, `.vult`, passwords), and direct network use of `github.com`, `docs.vultisig.com`, and `etherscan.io`.
