Prime services are the most gated product in finance. Leverage against a portfolio, access to trading venues, financing, yield on collateral that would otherwise sit idle, and liquidity without ever having to sell. Perhaps a few hundred institutions on earth get access to it. We want to change that.

Spot $BTC ETFs almost touch $1B as inflows hit 2026 high. Accumulating the world's hardest money.

Arch Prime brings prime services to Bitcoin. Native BTC collateral, borrowing, and yield in one margin account.

Speed or security? Why not both? Bitcoin’s slow confirmations were the price of safety. Arch changes that. Pre-confirmations and rollback protection enable sub-second responses without sacrificing Bitcoin’s security guarantees.

Most Bitcoin protocols execute somewhere else and reconcile with L1 later. ArchVM's syscalls construct the Bitcoin transaction during execution. Validators threshold-sign it. It settles on L1. All in 300ms blocks.

"Capital efficiency" is the most important idea in finance that nobody outside finance has ever been given. Let me translate it.

Bitcoin settles every ten minutes. Markets clear in milliseconds. That gap is the reason Bitcoin has no capital markets. Every attempt to close it so far has moved Bitcoin somewhere faster and left a receipt behind. Arch closes it without the BTC ever leaving. Here's how: → The UTXO gets an account. A real Bitcoin output on the base layer is bound to an Arch account that holds application state and program logic. Same output, now with a program attached. → Arch executes above it. A new block every 180 milliseconds, 1,500 TPS, an eBPF VM. State changes at market speed while the output underneath it does not move at all. → Control is split before it is ever used. Authority over that output exists only as shares distributed across validators through FROST/ROAST threshold signing. There is no single key anywhere, at any point. → Moving the BTC requires the network to agree. When a state transition calls for a spend, the shares combine into one signature. Not a custodian's discretion or a committee approval, but a cryptographic threshold. → Settlement is a Bitcoin transaction. One ordinary spend, one block, Bitcoin's own finality. Nothing to contest and nothing to unwind. Fast where it needs to be. Final where it counts. 180ms to execute. ~10 minutes to settle. One UTXO that was never wrapped, never rehypothecated, never off Bitcoin. Real Bitcoin. Finally programmable.
