South Korea’s largest digital asset custodian is taking its won-backed stablecoin global. BDACS has selected LayerZero’s Omnichain Fungible Token standard for KRW1, giving the Korean won-pegged stablecoin a unified cross-chain system as the company pushes the asset beyond its home market.
The technical change sounds mundane but matters enormously for a payments instrument. KRW1 already operates across several networks, including Ethereum, Avalanche, Polygon and Circle’s Arc — but those separate deployments created friction when moving the token between chains, limiting both distribution and utility. Under the new OFT setup, KRW1 will maintain a single unified supply across connected networks: tokens are debited on the source chain and credited on the destination chain, with LayerZero’s Stargate application handling transfers for end users. No bridge liquidity pools, no fragmented island versions of the same stablecoin.
LayerZero said its OFT standard already facilitates 87 percent of cross-chain transfer volume and has processed 280 billion USD in lifetime transfers across more than 170 blockchains. The standard is already used by some of the largest names in fiat-backed digital money, including Tether’s USDT0, PayPal USD and Paxos-issued USDG — a roster that puts KRW1 in decidedly serious company for a currency few outside Korea had heard of a year ago.
From Avalanche experiment to omnichain instrument
BDACS introduced KRW1 in September 2025 after completing a proof of concept with Woori Bank, launching the token on Avalanche with each unit backed 1:1 by Korean won held at the bank and an API connection for verifying reserves. The expansion came quickly: in October 2025 the company disclosed plans to issue KRW1 on Arc, Circle’s layer-1 blockchain designed for stablecoins, tokenized assets and programmable finance, and a Polygon deployment followed in December, positioned for payments, remittances and institutional transactions.
The LayerZero integration gives BDACS a common framework for managing the token as more chains are added, replacing disconnected token supplies with one auditable pool. Crucially, the issuer retains control over the token while gaining the ability to expand without creating isolated versions — the same omnichain structure USDT0 uses to move dollar liquidity between blockchains, and the same rails PayPal used to extend PYUSD to additional networks.
“The value of a Korean won stablecoin lies in its global scalability,” BDACS CEO Harry Ryoo said in announcing the move, adding that the company “will continue to expand the scope of KRW1’s use going forward” on the new technical foundation.
Riding a regulatory wave
The timing is no accident. South Korea is in the middle of an unusually active push to build won-denominated digital money infrastructure. The Bank of Korea reiterated in July that it favors a bank-led model for the initial stage of stablecoin issuance, with bank consortiums taking the lead while lawmakers negotiate the country’s Digital Asset Basic Act and related stablecoin rules.
Private companies are not waiting for the legislation. Financial super app Toss signed an agreement with Optimism and Sunnyside Labs in July for a three-month program examining won-linked stablecoin infrastructure, including payment settlement, compliance and privacy requirements. Telecom giant KT entered the same market with plans for a Token Factory and won stablecoin platform supporting token issuance, billing and settlement, drawing on K Bank, BC Card and its own network infrastructure.
Most consequentially, South Korea’s Won Internationalization Roadmap — published in July 2026 — calls for amendments to the Foreign Exchange Transactions Act to establish a legal basis for won-denominated stablecoins, alongside offshore won accounts and a 24-hour offshore won settlement network scheduled for pilot work into 2027. A globally portable won stablecoin is, in that light, less a crypto experiment than an instrument of monetary policy ambition.
The custodian behind the token
BDACS itself brings institutional credentials that most stablecoin issuers cannot match. The company surpassed 80 billion won in assets under custody during the first half of 2026, holds SOC 1 and ISO 27001 certifications, and is pursuing SOC 2 certification. Its existing partners include Woori Bank, Galaxy Digital and Circle. KRW1 will remain fully reserved 1:1 with Korean won held at Woori Bank as its network coverage expands, with independently attested reserves, according to the company.
For LayerZero, the deal extends a streak of regulated-money wins. In July the interoperability firm partnered with Keeta to make tokenized bank deposits transferable across Ethereum, Solana, Base and the Keeta Network, with nine fiat currencies in the planned rollout. Adding a non-dollar reserve asset to the OFT roster signals that omnichain infrastructure is becoming table stakes for any serious fiat-backed token — dollar, won or otherwise.
The open question is adoption: a unified supply solves the plumbing, but whether overseas users and institutions actually demand a won-pegged stablecoin at scale depends on trade flows, remittance corridors and the yet-to-be-finalized rules in Seoul. For now, BDACS has made sure that when that demand arrives, KRW1 will not be stuck on a single chain waiting for it.

KRW1 going omnichain makes sense, the separate versions on avalanche and polygon were a pain to move. tried bridging it back in july and it took forever
87 percent of cross chain volume running through one standard is the real story here. that is a lot of eggs in LayerZero’s basket
agreed, but the alternative is 170 bespoke bridges each with their own exploit history. one audited endpoint set is the lesser evil today
fair worry but the alternative was 170 custom bridges each getting drained on rotation. one audited standard beats a graveyard of them
a won stablecoin with global ambitions while domestic KRW token rules are still being fought over. bold play by BDACS
going global before the domestic KRW token rules settle is aggressive, but BDACS being the biggest custodian probably means they get to write half of them anyway
87 percent of cross chain volume thru OFT sounds great until you remember who controls the endpoint infra. still, KRW1 going omnichain day one beats the usual deploy on 6 chains and fragment liquidity playbook
endpoint control is my worry too, but wrapped won versions on every chain means six audit surfaces instead of one. pick your poison
The USDT0 and PYUSD comparisons are doing heavy lifting here. 280 billion in lifetime OFT transfers across 170 chains is the real pitch to issuers, not the Korea angle.
the 280 billion lifetime OFT number is the issuer pitch, agreed. what sells me more is the single unified supply with stargate routing and zero bridge pools fragmenting the token
fair point on endpoint control, but BDACS at least keeps custody of the reserves. the routing layer being LayerZero is a tradeoff id accept for unified supply over four fragmented deployments
finally. remitting won thru correspondent banks costs my mom like 15 bucks and takes 3 days. if KRW1 actually works across that many chains its a win for normal people
same for our seoul payroll runs. three days and correspondent bank fees every month. if stargate handles the transfer leg end to end this actually competes with wise on that corridor
payroll is the sleeper use case. if month end salaries settle in minutes instead of three days, finance teams switch and never look back
wise still owns the last mile to random local banks. KRW1 omnichain handles the chain hop, the offramp leg is still correspondent bank territory
15 bucks is real. the catch is mom needs a wallet that handles stargate transfers, the offramp back to a normal bank account is the leg nobody has solved yet
busan_baps nailed it, the wallet UX is the real gate. my mom uses kakao for everything, if KRW1 hops chains but she still cant cash out without a correspondent bank somewhere, adoption stays with us degen types
kakao pay adding KRW1 natively would do more for adoption than every chain integration combined. my father still asks if bitcoin is the one elon made
the offramp is solved the second a fintech embeds stargate transfers into a kakao connected app. the tech was never the holdup, licensing was
licensing was the holdup two years ago and OFT changes none of the paperwork. BDACS gets to say global now, the lawyers still do the actual walking
the offramp leg is the whole ballgame. my landlord does not accept stargate transfers, and until theres a kakao connected path back to a normal bank account this stays a defi toy
watching a won stablecoin ship omnichain before half of asia even tries. BDACS moving first is the whole moat here
single unified supply ends the wrapped-won era. market makers must be relieved, four fragmented deployments meant four spreads to babysit
Unified supply across Ethereum, Avalanche, Polygon and Arc fixes the fragmentation on paper. But the Bank of Korea has been circling stablecoin rules all year, one loud ruling and KRW1 goes global right back to local
the BoK angle is overblown tbh, they regulate issuers not transport standards. reserve rules were coming whether the token hops chains or not
