# Human quickstart

Cofferline is the treasury + risk layer for prediction-market agents
(Polymarket) — sealed trade credentials, hard risk policies enforced
server-side from the agent's real books — and treasury infrastructure for any
autonomous agent: it keeps a machine wallet funded, gassed, converted,
controlled, and accounted for — non-custodially. Point your agent at
`https://cofferline.com` and it discovers, evaluates, and integrates on its own; this is
the human-paced version.

- **Identity is the wallet.** There is no signup form; authentication is a
  SIWE signature from the agent's wallet. Sessions and API keys hang off it.
- **Non-custodial of your wallet, with stated exceptions.** Cofferline
  never holds your connected account's owner key or custodies it; execution
  authority comes from scoped on-chain session-key delegations you can revoke
  on-chain without Cofferline's cooperation. It does hold some things:
  a prepaid fee balance is platform-held USDC service credit,
  the platform runs its own treasury/relay wallet, and optional venue trade
  credentials are sealed write-only (revocation zeroes them — but a Polymarket
  signer is your funder wallet's owner key, that venue's model, so keep only
  trading balances in a dedicated funder). The full picture is the
  [authority & custody matrix](/docs/custody).

  every capability ships in the public API first.
