What this article covers

For about 18 months after Odyssey Chain mainnet (November 2024), Tangem cardholders had limited options for accessing their migrated DIONE. The Tangem app didn't include Odyssey Chain in its built-in network list, and direct integration with the DIONE ecosystem was pending.

That gap is now closed. DIONE Wallet v1.0.1 ships with direct Tangem support — connect your Tangem card to DIONE Wallet, sign Odyssey Chain transactions through the card, and your migrated DIONE is fully accessible without requiring seed phrase export.

This article walks through setup. If you're a Tangem holder who's been waiting since 2024, this is the resolution.

Step 1 — Confirm your Tangem card is compatible

DIONE Wallet's Tangem integration uses Tangem's standard NFC pairing protocol. Cards in the Tangem Wallet 2.0 product line and later are compatible. Some older Tangem cards (early single-card products from 2020-2022) may have limitations.

Quick compatibility check:

1. Open the Tangem app
2. Scan your card
3. In card settings, look for "External wallet pairing" or equivalent option

If the option exists, your card is compatible with the direct integration. If not, see Step 5 for the seed-phrase path.

Step 2 — Install DIONE Wallet

Download DIONE Wallet only from dionewallet.com/download or our verified GitHub Releases page (where installer binaries are mirrored). The team will never DM you a download link.

Run the installer. On first launch, you'll see two paths:

• Create new wallet — generates a fresh seed phrase
• Connect hardware wallet — pairs an existing hardware wallet

Choose Connect hardware wallet.

Step 3 — Pair your Tangem card

DIONE Wallet shows the supported hardware wallet options: Ledger, Trezor, Tangem.

1. Select Tangem
2. The wallet displays a pairing screen with NFC instructions
3. On a desktop with NFC reader: tap your Tangem card to the reader
4. On a desktop without NFC reader: a QR code appears — open the Tangem app on your phone, scan the QR code, then tap your card to your phone to authorize the pairing
5. Confirm the pairing in the Tangem app
6. DIONE Wallet recognizes the card and displays the connected address

Your 0x... address is the same one you've been using in the Tangem app for compatible chains. Odyssey Chain is now visible from DIONE Wallet at that address.

Step 4 — Verify your migrated DIONE

After pairing, DIONE Wallet syncs with Odyssey Chain and displays your balance.

If you held DIONE as ERC-20 before November 2024, your migrated balance should appear immediately — the migration was 1:1 to the same address derived from your Tangem card.

If the balance shows zero but you remember holding DIONE pre-mainnet:

1. Open odysseyscan.com and paste the address from your Tangem card
2. Confirm what's actually on-chain
3. If OdysseyScan shows DIONE but DIONE Wallet shows zero, the issue is sync — refresh the wallet or reconnect

Step 5 — Alternative path for older cards

If your Tangem card doesn't support the direct NFC pairing flow in Step 3, we recommend against typing your card's recovery phrase into DIONE Wallet (or any other app). Moving a seed phrase between two separate applications means the same private key now exists in two codebases — a bug or compromise in either one exposes both.

The safer alternative:

1. In DIONE Wallet, choose Create new wallet to generate a fresh, DIONE-Wallet-only seed phrase
2. Use the Tangem app itself to send your DIONE balance on-chain to your new DIONE Wallet address
3. Confirm the balance arrives in DIONE Wallet

This costs a small on-chain transaction fee but keeps your Tangem card's original key isolated to the Tangem app, and DIONE Wallet's key isolated to DIONE Wallet. Most users then use DIONE Wallet for active operations and keep the Tangem card as a separate cold-storage backup.

Step 6 — Signing transactions

Once paired, every Odyssey Chain transaction you initiate in DIONE Wallet routes to the Tangem card for signing.

For sending DIONE or interacting with a dApp:

1. Initiate the transaction in DIONE Wallet (e.g., click Send, fill in destination + amount)
2. Review the transaction details
3. DIONE Wallet prompts: "Tap Tangem card to sign"
4. Tap the card to your phone (if paired via mobile) or NFC reader (if paired directly to desktop)
5. The card signs internally; the signed transaction broadcasts to Odyssey Chain
6. Confirmation appears in DIONE Wallet within seconds

Private keys never leave the Tangem card. DIONE Wallet is the UI; the card is the signing authority.
