SideShift Review

How SideShift works

You select the coin to send and the coin you wish to receive, paste your receiving address, and then send the deposit. According to SideShift's terms, it does not offer custodial services, meaning no balance is held in an account between the two legs of the swap. You don't need an account to swap, although SideShift's risk policy indicates that verified users may receive refunds more quickly.

There are two types of rates available. A fixed shift secures the rate for 15 minutes, including all fees, and a deposit made after the fixed shift expires will be refunded. A variable shift applies the rate at the time your deposit is received and remains valid for seven days.

Paradigm Ltd operates SideShift.ai and also offers an Android app on Google Play. On SideShift's homepage, Trezor, Bitcoin.com, Edge, and Aqua Wallet are listed under the heading "Trusted By".

The XAI token

SideShift's own token, XAI, runs on Ethereum and has a total supply of 210,000,000. It no longer pays staking rewards: according to SideShift's white paper, XAI staking rewards ended on June 3, 2026.

Fees and what a swap costs

SideShift publishes no fee percentage. Its terms say you pay the fees "as defined by SideShift AI, which we may change from time to time", and the rate you see already includes them, together with an estimate of the network fee. In our view, the way to judge the cost is to compare the quote with the market rate.

Our rate snapshot does that with indicative quotes from each provider's public price endpoint, measured against the mid-market rate with network fees included as far as each endpoint shows them. On a 0.1 BTC to ETH quote, SideShift's variable rate came out 1.889% below the mid-market rate, against 1.203% for ChangeNOW's standard rate and 0.584% for FixedFloat's float rate. On all three pairs in the snapshot, its variable rate cost more than both of those rates.

Limits, checks and refunds

Limits vary by pair and fluctuate with liquidity. In our snapshot, a BTC to ETH shift could reach up to 0.73470012 BTC, and a USDT (TRC20) to BTC shift could be as large as 60,000 USDT.

Swapping without an account is possible, but SideShift screens deposits. Its risk management policy indicates that a shift is flagged and paused for human review if the deposit transaction or receiving address is associated with illegal or malicious activity. Users with serious flagged deposits must complete verification before a refund is processed. If a deposit is deemed unacceptable, the account is suspended and the deposit is refunded after a holding period. SideShift's terms also permit the freezing of a swap during a risk investigation.

Swapping without an account does not mean no data is retained. SideShift's privacy policy describes how Paradigm Ltd collects, uses, shares and protects personal information, including contact, account, transaction and verification data.

If you provide a refund address when creating a shift, SideShift's documentation states that refunds are processed automatically. The documentation gives no time frame for refunds.

Where you can use it

As per its terms, SideShift.ai is not intended for citizens, nationals, or residents of the United States, Cuba, Iran, North Korea, Saint Kitts and Nevis, or Syria. If you live in the US, you can use ChangeNOW only with an account and identity checks, in the 40 states plus DC its Pro terms name, and Coinbase serves every US state.

Operator and track record

SideShift.ai is operated by Paradigm Ltd. Its legal page provides a mailing address in Basseterre on Saint Kitts, but no country of registration is mentioned. Saint Kitts and Nevis is listed among SideShift's excluded countries. We found no entry for SideShift or Paradigm Ltd in the European interim register of authorized crypto-asset service providers.

As a non-custodial service that holds no customer balances, SideShift publishes no proof of reserves.

Alternatives to SideShift

If you are new to crypto and want to pay by card, a swap service is not the easiest start. In our view, Coinbase is the simpler first step for US readers, and ChangeNOW lets you buy crypto by card through partners such as Guardarian, Banxa and Transak.

If cost matters most, FixedFloat publishes its fees, 0.5% on a float rate and 1% on a fixed rate plus the network fee, and its quotes cost the least of the six in our latest rate snapshot; its terms exclude US citizens and residents. Our instant swap overview puts the swap services we cover side by side, and our list of exchanges for US customers shows which provider serves which state.

Is SideShift legit?

In our view, SideShift.ai is a real, active swap service, but the company behind it tells you little about itself. Paradigm Ltd operates it. Its legal page gives a mailing address in Basseterre on Saint Kitts but names no country of registration, and Saint Kitts and Nevis is on SideShift's own list of excluded countries. We found no entry for SideShift or Paradigm Ltd in the European interim register of authorized crypto-asset service providers.

What benefits you: SideShift does not offer custodial services, so no balance is maintained for you between the two legs of a swap. With no customer balances, it doesn't publish proof of reserves. No account is needed, and refunds are automatically processed when a refund address is set.

Account-free doesn't mean unchecked. SideShift screens each transaction using an automated risk system, and flagged transactions are paused for human review. These can be frozen during investigations, and seriously flagged deposits require verification for a refund. In our view, it is a reasonable option for crypto-to-crypto swaps if you accept the gaps in its operator's disclosures, set a refund address, and compare each quote in advance.

SideShift fees

SideShift publishes no fee percentage: its fee and an estimate of the network fee are built into the rate it quotes.

• Fixed shift: the rate is locked for 15 minutes, including all fees.
• Variable shift: the rate is determined when your deposit arrives, with network fees included.
• In our latest rate snapshot, its quotes ranged from 1.889% to 2.226% below the mid-market rate on three pairs, 1.889% on a 0.1 BTC to ETH quote.
• During the same snapshot, SideShift's variable-rate quotes were more expensive than the standard rate of ChangeNOW and the floating rate of FixedFloat across all three pairs.
• No card or bank payments, hence no card or bank fees.

In our view, compare the quote with another service's quote for the same amount before sending.

SideShift FAQ

Does SideShift require KYC?

No account is needed for swapping. The risk policy associates verification with flagged deposits. SideShift monitors both deposits and receiving addresses, halts flagged shifts for manual review, and requests verification prior to refunding a flagged deposit of a serious nature.

Can you use SideShift in the US?

Not through sideshift.ai, whose terms exclude US residents. If you live in the US, our ChangeNOW and Coinbase reviews cover two services that do serve US residents, ChangeNOW only with an account and identity checks.
