TrufflΣ is a fast, self-custodial mobile trading app and wallet for the Ergo blockchain. It's built for traders who want to act quickly without giving up control — you stay on-chain, you hold your keys, and every swap lands directly in a DEX pool with no middlemen. It supports traditional wallet transctions and connecting to supported dapps via ErgoPay..
It supports Spectrum/ErgoDEX liquidity pools for token swaps, and the USE, SigUSD/SigRSV and DexyGold stablecoin protocols for minting and redeeming. Transactions can be signed securely via ErgoPay (recommended), or you can import a mnemonic and sign directly in the app.
Warning
BETA SOFTWARE: TrufflΣ is currently in beta. Always verify all transaction details and output amounts before confirming. Use at your own risk!
As an Open Source project, the community is invited to audit the code for vulnerabilities. Transparency is key to building a secure tool for everyone.

Swap ERG ↔ Token, Token ↔ ERG, and Token ↔ Token across all Spectrum pools. The app has a pre-approve whitelist, but you can discover and add new pools using user whitelist. All data is fetched from the blockchain. Price quotes update as you type, including price impact and LP fee breakdowns. A customizable miner fee slider gives you full control over transaction speed.
See your full wallet balance enriched with live DEX prices — each token shows its current ERG price and its equivalent $USE value so you always know what your holdings are worth in real terms.
A swipeable chart card shows ERG/USD price history from multiple on-chain sources: the USE oracle, the SigUSD oracle, and the SigUSD DEX pool. You can also select any individual token from the dropdown to view its historical ERG price from pool state data. Time ranges from 24H all the way to MAX.
When you select a token pair in the chart, a Latest Trades view appears — showing the last ~15 real on-chain swaps with direction (buy/sell), amounts, trader address, time ago, and a direct explorer link.
A live feed of everything happening on-chain across the Ergo DeFi ecosystem — DEX swaps, stablecoin mints and redeems (SigUSD, SigRSV, USE, DexyGold), LP actions, and oracle updates. Filter by category, pull to refresh, and scroll infinitely.
Mint and redeem SigUSD, SigRSV, USE, and DexyGold directly from the app. The Bank tab shows live protocol status, reserve ratios, available capacity, and fee breakdowns. Blocked operations show an expandable explanation so you always know why something isn't available right now.
Send ERG and tokens to one or multiple recipients in a single transaction. The Send screen supports QR code scanning for addresses, a token multiselect showing all tokens in your wallet, and a miner fee slider. A full review screen shows you exactly what's going out before you sign.
TrufflΣ handles ergopay: URIs natively — scan a QR code from any dApp or click an ErgoPay link and the app opens the transaction for review. A detailed per-address breakdown shows net changes for your wallet, contracts, fees, and external addresses before you confirm.
Import a mnemonic and the app automatically scans your derivation path to find all your active addresses. You can pick which addresses to trade from, set a change address, and see balances aggregated across all of them. Transaction history covers every address in your wallet.
- ErgoPay (Recommended): Add your public address only. Trades generate a signing request for your external wallet — your mnemonic never enters this app.
- Mnemonic (Hot Wallet): Import your seed phrase and encrypt it with a password or with biometrics (face/fingerprint). Transactions are signed locally on your device.

Go to the Wallet tab and tap the + button. Choose ErgoPay (address-only, safest) or import a mnemonic. On mnemonic import, the app scans the blockchain to find all your active addresses automatically.
The DEX screen has a quick-pick Favorites grid — tap any asset to instantly set it as your swap target. Tap the Edit toggle to customise which tokens appear. You can configure how many favorites are shown in Settings.
Tap Send from the Wallet tab. Enter a recipient address (or scan a QR code), set the ERG amount, and optionally add tokens from your balance. Add multiple recipients if needed. Review the transaction summary, then sign with your password or biometrics.
TrufflΣ ships with a set of public Ergo nodes and automatically distributes requests across them for speed and resilience. You can add your own node URL in Settings → Network for maximum reliability.
In Settings → Advanced, you can enable Check TX mode — transactions are validated by the node but never broadcast. Useful for verifying amounts before going live.
TrufflΣ is built to be fast and direct:
- Pool data and token metadata are cached locally so the app is ready instantly on launch.
- The node pool distributes read requests across multiple nodes in parallel for snappy quotes and balance fetches.
- The UI updates progressively as data arrives — you see prices and balances as soon as they're ready, not after a full sync completes.
- You can always refresh the token list manually in Settings → Token List to pick up newly added pools.
Built on the Ergo blockchain. Transaction signing powered by sigma-rust. DEX contracts by Spectrum Finance.
