SideShift.ai

Risk-based KYC Instant swap no account

5.8/10 total

Direct-to-wallet swapping with no signup, operated by Paradigm Ltd in Basseterre, St Kitts. The public API lists 196 coins across 47 networks. The catch is written into the terms: every transaction goes through an automated risk system, and the published risk-management policy says a flagged deposit is paused for human review, the deposit is refunded only after a holding period, and serious flags require the user to complete verification before that refund is released.

Weights are published in the method and applied identically to every entry.

For

  • No account, email or wallet connection needed for a swap; accounts exist only for XAI staking and API keys
  • Public REST API with machine-readable coin and pair endpoints that respond without any key
  • Terms and risk-management policy are published and specific rather than boilerplate
  • Long operating history for this sector, integrated by Trezor, Edge and Bitcoin.com

Against

  • Terms state SideShift "reserves the right to freeze your exchange transaction" during a risk investigation, and flagged users must verify identity to get a refund on serious flags
  • Blocks US, Cuba, Iran, North Korea, Syria and St Kitts residents by terms
  • No onion service and no working no-JavaScript path
  • Fee is never stated as a number anywhere in official documentation

Agent access 7/10

Coin, pair and quote endpoints answered unauthenticated during testing, but creating a shift needs an x-sideshift-secret private key plus an affiliateId from a dashboard account. The account is free and needs no identity documents, so an agent can be provisioned once and then run unattended.

Reported separately and not counted in the total. It measures what an autonomous agent can do unattended, not whether the service is safe to use.

Fees

embedded in rate

No separately itemised fee: the markup lives inside the quoted rate, and the company's own integration doc says only that "shift fees are integrated into the rate shown to your users". Published 0.5-1% figures come from review sites that carry affiliate links, so treat the real spread as unmeasured until you compare a quote against spot yourself.
