What is Flashnet? How Flashnet swaps work
Fast cross-chain settlement network.
How Flashnet settles cross-chain swaps, which networks it covers on TorrentSwap, and when it is the fastest route.
- Typical time
- Often the fastest route: about 1 minute between EVM chains and Solana, around 10 minutes with Bitcoin.
- How your deposit is held
- Held briefly at a Flashnet deposit address while the swap settles.
How a Flashnet swap works
- 01You get a one-time Flashnet deposit address for your quote.
- 02Once the deposit confirms, Flashnet settles the swap and pays out on the destination network.
- 03If the swap cannot be completed within your minimum, the deposit is refunded.
Flashnet in one paragraph
Flashnet is a Bitcoin and stablecoin company built around Spark, the Bitcoin layer 2 developed with Lightspark, and is one of Spark's founding operators alongside Lightspark and Breez. It runs two things: an AMM on Spark for BTC, the USDB dollar stablecoin and Spark tokens, and Orchestra, an API that moves assets across chains through deposit addresses. TorrentSwap's Flashnet routes use Orchestra. Flashnet raised a reported $4.5 million seed round led by Abstract in early 2025 and has no token of its own.
How Orchestra quotes and fees work
An Orchestra quote returns a deposit address, the input amount, the estimated output and an expiry: quotes are valid for two minutes, and the order is created automatically when the deposit is detected. Bitcoin deposits wait for one confirmation (about ten minutes on average) unless an optional ZeroConf offer credits them sooner for a fee.
Flashnet does not publish a single fee schedule: platform fees depend on the route and are shown in each quote. On TorrentSwap they are already inside the amount you see, together with every other fee.
Custody, compliance and security
Flashnet's compliance page says it settles orders without taking custody and holds no user balances. Spark itself is designed so users can exit to Bitcoin layer 1 unilaterally with pre-signed transactions. Orchestra exposes AWS Nitro Enclave attestation so integrators can verify the worker that processes orders, and every order address is screened with Elliptic and other providers; sanctioned addresses are rejected and high-risk orders held for review. We found no published audits or bug bounty, and no reported exploits or halts as of 22 October 2026.
Tips for Flashnet routes
From Flashnet's documentation:
- Fund within the quote window and send the exact amount; late deposits may be re-priced or held for review
- Mind the minimums: about 5,000 sats when swapping from Bitcoin layer 1 and 10,000 sats for delivery to it
- Give a refund address: it is required for some sources and keeps refunds away from exchange hot wallets
- Don't use replace-by-fee on a BTC deposit: a replaced transaction leaves the original order unfulfilled until it is matched
Where it shines
- Frequently the fastest option, which is why it often carries the Fastest badge.
- Only protocol on TorrentSwap covering BNB Chain today.
Trade-offs
- Tends to price small swaps less competitively — compare the amount received.
- Flashnet publishes little detail about its custody model; funds sit at a Flashnet deposit address until settlement.
