features:
  - title: Managed EIP-7702 relay
    details: A user signs a 7702 authorization + batch digest; Kryard signs, fronts gas, and broadcasts the type-4 transaction. Smart-wallet UX with no 4337 bundler.
  - title: Pay gas in any token
    details: Users settle gas in any ERC-20. The on-chain KryardDelegate reimburses the relayer an exact, user-signed fee that can't be inflated.
  - title: Turnkey-wire-compatible
    details: A drop-in replacement for Turnkey's secp256k1 EVM signing — cutover is a single TURNKEY_BASE_URL swap, zero client changes.
  - title: Thin, dependency-light SDK
    details: "@kryard/sdk — signAuthorization → sponsored execute. Built-in MIT X-Stamp signer, viem peer dep, on npm + GitHub Packages."
