KRW1 Explained: What BDACS Proved With Its Won Stablecoin PoC
KRW1 is a Korean won-denominated stablecoin developed by digital-asset custodian BDACS. In September 2025, the company announced that it had completed a proof of concept covering reserve deposit, token issuance, on-chain verification and transfers on Avalanche.
The wording matters. Public materials describe a technically completed PoC and a reserve account at a commercial bank. That is not the same as saying a bank issued the token, that KRW1 is generally available to the public or that every regulatory condition for commercial circulation has been completed.
Key takeaways
BDACS, rather than Woori Bank, is identified as the developer and issuer in the project materials.
The PoC was designed around 100% Korean-won backing held in a commercial-bank account.
A working mint, transfer and verification process proves technical flow; it does not by itself prove public redemption, market liquidity or regulatory approval.
Before using KRW1, a user or partner should verify the current legal status, eligible holders, reserve reporting and operational redemption route.
What the proof of concept tested
According to BDACS, won collateral was deposited and checked before tokens were issued on Avalanche. The project also developed an application for transfers and verification. Its English PoC paper describes segregated reserves, authorised holders and a process in which tokens sent for redemption would be burned under the issuer’s controls.
This is a conventional fiat-backed design in principle: token liabilities should be matched by money held off-chain. The blockchain can show token supply and transfers, but it cannot independently prove the balance or legal availability of the bank account. That requires reliable attestations, audits and enforceable issuer obligations.
Five questions that determine whether the model is usable
Who may hold and redeem? Public trading is different from a controlled institutional test.
What is the legal claim? Holders need clear terms identifying the issuer and their right to repayment.
How are reserves reported? API checks, attestations and audited financial statements provide different levels of assurance.
Which contract is canonical? Similar tickers and unofficial wrapped versions can mislead users.
What happens during suspension or insolvency? Redemption timing, fees and reserve segregation matter most under stress.
What teams should communicate
A stablecoin announcement should distinguish what is live, what was tested and what is planned. Avoid phrases such as “bank-issued,” “fully regulated” or “guaranteed” unless the responsible institution and legal basis support them directly. State the chain, issuer, reserve custodian, eligible users and date of the evidence.
