Terms of Service
Last updated: January 2026
1. Introduction
These Terms of Service ("Terms") govern your use of cirbtc2bitcoin.com, an atomic swap service powered by Satora and operated by Lendasat Inc., a Delaware C Corporation ("Company", "we", "us", or "our"). By accessing or using our service, you agree to be bound by these Terms.2. Service Description
cirbtc2bitcoin.com provides an atomic swap service that enables users to exchange cirBTC for Bitcoin (BTC) on Lightning, on-chain or Arkade, and vice versa. cirBTC is a BTC-backed token issued by Circle. cirbtc2bitcoin.com is an independent service and is not affiliated with Circle.
A swap from cirBTC to BTC runs through the following steps:
- Your cirBTC is converted to tBTC, a BTC-pegged token on Ethereum, on a decentralized exchange.
- The tBTC is locked in a hash time-locked contract (HTLC).
- The server locks the corresponding amount of BTC.
- You receive the BTC at your target address, which atomically releases the tBTC to the server.
A swap from BTC to cirBTC runs the same way in reverse: you lock BTC, the server locks tBTC on Ethereum, and on claim it is converted to cirBTC and sent to your address.
3. Refund Policy
If a swap cannot be completed, the locked funds are returned once the contract's timelock expires. What you receive depends on the direction of the swap:
- cirBTC to BTC: you receive tBTC on Ethereum, not cirBTC. The cirBTC has already been converted to tBTC before it was locked, and that conversion is not reversed.
- BTC to cirBTC: you receive your original BTC back to a refund address you control.
4. Exchange Rate Risk
IMPORTANT: cirBTC is converted to or from tBTC on a decentralized exchange as part of the swap, at the market rate at that moment, and a refund of a cirBTC to BTC swap is paid in tBTC. cirBTC and tBTC are tokens issued by third parties. We do not issue them, and we make no guarantee about their market value relative to BTC or to each other, before or after a swap or a refund.
We do not provide any guarantees regarding exchange rates. Rates may fluctuate between the time you initiate a swap and when it is executed. You acknowledge and accept this risk when using our service.
