The problem
Every large order on a public exchange announces itself before it fills. Bots read the mempool, the curve takes its cut, and the market moves against you. Sable Vault moves the trade off the tape entirely.
How it works
Three steps. No order book.
Sable Vault replaces public price discovery with a direct, sealed handoff between two parties.
01
Lock the block
Choose your size and set a price in USDC or tBTC. A fresh escrow vault is generated in your browser and funded straight from your wallet.
02
Hand off the note
You receive a sealed Vault Note carrying the terms. Share it privately with your counterparty.
03
Pay & settle in one click
The counterparty approves once: the USDC or tBTC payment reaches your wallet and the SOL lands in their fresh, unlinked address — all in a single atomic transaction.
Why OTC
Public AMMs punish size.
Routing a large block through a public pool leaks intent and pays the curve. A sealed escrow does neither.
Security
Built for desks that can't afford a leak.
Client-side vaults
Escrow keys are generated in your browser with @solana/web3.js. They never touch a server.
Non-custodial
No relayer holds your funds. The note is the key; whoever holds it controls the vault.
Phantom & Solflare
Connect the wallet you already use. Every deposit is a standard, signed Solana transfer.
On-chain verification
Balances are read live over RPC before settlement, and every transaction links to Solscan.
Fresh-address delivery
Settle to any unlinked wallet, breaking the trail between deposit and receipt.
Instant quote-side payment
USDC or tBTC payment and SOL delivery settle in a single atomic transaction — no waiting, no separate wire.
Post-quantum roadmap
Lattice-based note commitments are planned to protect orders against future quantum attacks.
FAQ
Questions, answered.
What happens if I lose the note?+
The funds in that vault can't be recovered. Store the note like a private key.
How does my counterparty pay me?+
Instantly, on this site. The note carries your price and payout address; the buyer connects a wallet holding USDC or tBTC and clicks Pay & Settle. Payment and SOL delivery happen in one transaction.
Is the protocol audited?+
Yes. The project owner confirms that Sable Vault has been audited. An audit does not eliminate risk; protect your Vault Note and review each transaction before signing.
Which wallets are supported?+
Phantom and Solflare on Solana Mainnet.
