Solana has a few privacy tools. HEAA Dark Pool is built to be the simplest and most practical of them for real, everyday use. ### Private by default, not as an afterthought Most privacy tools on Solana are built around a single action — usually mixing or a one-off private send. HEAA Dark Pool treats privacy as a place you operate from. You shield once, and from then on your balance lives in an encrypted account. Sending, swapping, and receiving all happen from that private state, not as isolated one-time tricks. ### One command, not ten steps Selling a token privately normally means juggling several manual steps: swap the token, wrap the proceeds, move them into a private pool, then send. HEAA Dark Pool collapses all of that into a single instruction you can type in plain language: > *sell all of my BONK privately to \* The dApp figures out the token, the amounts, and every step in between, and executes them in order. You approve, and it runs. ### Truly non-custodial Your private keys are generated on your device and never leave it. HEAA never takes custody of your funds or your secrets at any point. Even while a private swap is running, the assets stay under keys you control — nothing is ever parked in an account the operator can touch. ### Real efficiency Because the whole flow is orchestrated for you, there's no wasted movement. Funds take the shortest path from "in your wallet" to "privately delivered," and unnecessary conversions are avoided wherever possible. When you already hold a private balance, a send draws straight from it instead of re-shielding from scratch. ### Cleaner experience A fast, terminal-style interface shows you exactly what you hold — both your public wallet balance and your encrypted balance — side by side, with live feedback at every step. No guesswork about whether something went through.
