About Flip

Flip is a non-custodial cross-chain swap interface that includes native Bitcoin. Built for people who refuse to wrap their BTC, trust a centralized exchange to move it onchain, or pay 2-5% in CEX withdrawal fees to do what should be one signature.

The problem

Most cross-chain swap UIs are EVM-only. The ones that include Bitcoin route through wrapped variants — WBTC, BTCB, cbBTC — which means trusting a custodian (BitGo, Coinbase, Binance) to mint and redeem the underlying BTC. That's not Bitcoin custody. It's an IOU backed by a company.

The alternative most users default to is a centralized exchange: deposit, sell, withdraw to the destination chain. Two custodial legs, KYC, 30+ minutes, and 0.5-1% lost to trading + withdrawal fees on a small swap.

Flip routes between actual Bitcoin on the actual Bitcoin network and any chain it supports using a solver network with on-chain enforcement. No wrap. No custodian. One signature.

How it works

Flip is built on the NEAR Intents 1Click protocol — an intent-based settlement network where independent solvers compete to fill cross-chain orders. The protocol enforces solver collateral and refund rules on-chain, so a failed or partial fill triggers an automatic refund to the user's refund address.

The user signs one transaction in their own wallet to deposit the source asset. Solvers race to deliver the destination asset to the user's wallet. Both legs are publicly visible on the respective block explorers — see the Trust & security page for the full mechanism and how to verify any swap independently.

Chains supported

Bitcoin (native L1), Ethereum mainnet, Arbitrum, Base, Solana, NEAR. New chains are added as the underlying settlement protocol expands coverage.

Fees

One flat protocol fee, displayed in every quote before you execute and shown on the welcome modal. The number is read directly from a deployed environment variable, so the displayed fee can never drift from what the API actually charges.

Flip does not collect any other fees, spreads, or markups. The on-chain network fees (Bitcoin tx fee, Ethereum gas, etc.) are outside Flip's control and are deducted by the destination chain itself, not by Flip.

The team

Flip is built by a small, deliberately-tight team working across product, protocol integration, and infrastructure. We keep the surface narrow so every line of code on the page is one a team member could explain end-to-end — the opposite of a feature race.

Founded in 2026 by Myer. The codebase is private; if you're a serious partner, acquirer, or investor and want an architecture walkthrough, the contact addresses below open a conversation.

What's next

Active development continues along the obvious lines: sharpening the BTC-native experience end-to-end, surfacing more of the measurable quality behind every quote rather than asking users to take the savings claim on faith, and meeting users on the surfaces where they actually trade — which is sometimes not a web browser.

Specific timelines, integration order, and channel priorities aren't published here. If you're a partner, investor, or acquirer who needs more, the contact address below opens a conversation.
