Wrapped DOI — Doichain made accessible on Ethereum.
wDOI is an ERC-20 representation backed 1:1 by native DOI. It opens a productive, Bitcoin-related blockchain and a real-world lab for post-quantum migration to the Ethereum ecosystem for the first time — DEX, DeFi, smart-contract logic. Not a separate speculative construct, but access to the substance of Doichain.
Why now
- In production since 2018
Bitcoin-related PoW chain, secured via merged mining.
- PQC real-world lab
Three-phase plan 2026–2031 for the post-quantum migration.
- First-time ERC-20
Backed 1:1 on Ethereum — usable in DEX, DeFi and smart contracts.

How the reservation works
- 01Express interest
Fill in the form: name, email, requested wDOI amount, brief background. Non-binding.
- 02Double opt-in
Click the confirmation link in the incoming email. The confirmation is anchored on Doichain as a hash.
- 03Notification of final terms
After the registration deadline we'll email you with the final allocation, payment terms and recipient wallet.
- 04Pro-rata allocation if oversubscribed
If the sum of requests exceeds the available volume, allocation is pro rata — fair and transparent.
- 05Payout to Ethereum wallet
Once the EUR payment (SEPA transfer) has arrived, wDOI is paid out as an ERC-20 token to the Ethereum address you provided.
Tokenomics & architecture
wDOI is not newly created value, but a technical wrapper around native DOI. For every wDOI issued, exactly one DOI is held in custody on Doichain. On redemption, wDOI is burned and the held DOI is released.
What does my wDOI stand for?
The economic value of wDOI is a derived value — it rests on the substance of Doichain. Three pillars, three verifiable sources.
Productive applications
Double opt-in, DoiWallet, BlockPro pilot, namespace layer — each with stated status.

wDOI is a standard ERC-20 token on Ethereum. Any wallet that supports ERC-20 can receive, hold and send wDOI. Recommended for payout:
Custodial exchange wallets only support wDOI if the exchange has listed the token. Payout requires a self-custodied Ethereum address.
What can go wrong
Anyone holding wDOI takes on the following risks. They aren't in the small print — they're laid out here.
Market risk
The market price of wDOI after issue is unpredictable. It can sit below the issue price, stay there for a long time, or fall further. There is no commitment to buy back at the issue price.
Bridge risk
The Doichain bridge connects two chains via multisig custody and smart contracts. Smart-contract bugs, compromised signer keys or consensus failures on either chain can cause losses. Audits and proof of reserves reduce the risk but do not eliminate it.
Regulatory risk
The legal classification of tokens is evolving. New rules — MiCAR, national interpretations, tax law — may change the availability, trading or custody of wDOI. People in certain countries may be excluded from participation.
Liquidity risk
In the early phase, secondary-market liquidity is thin. Even when wDOI is listed on DEXes, tight spreads, large volumes or fast exits are not guaranteed. Plan for the possibility of having to hold wDOI for longer.
