What you can do on Blast

  • Vault wallets

    Keys generated and sealed in the vault (AES-256-GCM, per-organization key), never shown.

  • Split keys 2-of-2

    Half of each key stays on your own co-signer: a breach of Chainvara alone cannot move funds.

  • Policies & approvals

    Per-transfer and daily caps, approval tiers, address book with cooldown, two-factor.

  • Send & receive

    Fees quoted and checked before signing, every transfer tracked to finality.

  • Wallet API

    One wallet per end user, idempotent transfers, signed webhooks.

  • Sanctions screening

    Destinations checked against the OFAC SDN list before every transfer.

  • Token issuance

    ERC-20 contracts deployed from the vault; mint and burn under approval.

  • DeFi apps

    Connect a vault wallet to dApps through WalletConnect, every request approved.
