Korea Blockchain Week 2026 Checklist: Data, Money and Seoul Tips for KBW

KBW 2026 runs 29 September to 1 October at Walkerhill in Seoul. Seoul is easy once you are set up, and awkward if you are not. Here is the checklist.

Quick answer: Korea Blockchain Week 2026 runs 29 September to 1 October at Walkerhill Hotels & Resorts, Seoul, with the main conference on 30 September and 1 October. Before you fly: install a Korea eSIM at home, download Naver Map or KakaoMap (as of September 2026, Google Maps directions are still limited in Korea), plan a T-money card for transport, and check whether you need a K-ETA.

Key takeaways

KBW 2026: 29 September institutional forum, 30 September to 1 October main conference, at Walkerhill in east Seoul.
As of September 2026, Google Maps gives limited walking and driving directions in Korea. Install Naver Map or KakaoMap before you land.
Side events spread across Gangnam, Seongsu and other districts every night of KBW week. You will navigate them on mobile data.
A T-money card covers subway, buses and many convenience stores.
K-ETA temporary exemption runs to 31 December 2026 for eligible nationalities. Check the official list.

Seoul during Korea Blockchain Week is a city-wide event. The conference sits at Walkerhill on the east side, while the dinners, parties and side events scatter across Gangnam, Seongsu, Itaewon and beyond. The people who get the most out of the week are the ones who can move between them without thinking: phone online, maps that work, transport card in pocket.

Here is how to arrive that way.

Pre-flight checklist for KBW

Phone: eSIM-capable and carrier-unlocked. Check before you buy.
Travel eSIM installed at home on Wi-Fi, switched on after landing. Keep your home SIM active for bank and 2FA codes.
Power bank (carry-on only, check your airline's limits) and a short cable. Conference days drain phones fast.
Hotspot plan check: if you demo from a laptop or share with a teammate, pick a plan that allows tethering.
Hardware wallet or a separate event wallet if you will be signing anything on site.
Offline copies: hotel address in the local language, booking confirmations, and your ticket QR as a screenshot.
Naver Map or KakaoMap installed and set to English. Google Maps works for public transit but gives limited walking and driving directions in Korea.
Kakao T for taxis. Registration and payment options for foreign users change, so set it up and test before you rely on it.
K-ETA check: eligible nationalities are temporarily exempt until 31 December 2026. Confirm your status on the official K-ETA site.

Why mobile data matters more in Seoul than you think

Seoul has excellent coverage and free Wi-Fi in many places, which makes it tempting to skip data. The catch is event week: you are moving between the venue and side events in districts you do not know, and the map apps you need are only useful online.

Walkerhill to Gangnam and other side-event districts is a real journey, not a walk.
Side event details change last minute on Luma, Telegram and X.
Taxi apps and translation need a live connection on the street.
Venue networks are shared by thousands of attendees during keynotes and demo sessions.

Korea plans on the Fizen eSIM page are listed with their current prices in the app. For a full KBW week of maps, messaging and occasional hotspot use, pick a plan with comfortable data headroom, or unlimited if you hotspot a laptop. See also our South Korea eSIM guide.

Money in Seoul: cards, T-money and cash

Situation	What usually works	Tip
Subway and buses	T-money card	Buy at convenience stores; top-ups are usually cash. iPhone: add T-money in Apple Wallet via the Tmoney app and top up with Mastercard, Amex or UnionPay (not Visa yet)
Cafes, restaurants, taxis	International cards widely accepted	Carry a backup card
Traditional markets and small stalls	Cash, sometimes cards	Keep some won in cash
Getting cash	Global ATMs at banks and convenience stores	Check fees shown on screen

Korea is one of the most card-friendly countries in Asia, so most attendees barely touch cash. A T-money card and one or two international cards cover almost everything. Keep a small amount of won for markets and the occasional place that does not take your card.

How to set up your Korea eSIM in 5 steps

Check your phone supports eSIM and is carrier-unlocked.
Choose a South Korea plan on fizen.io/esim for the full length of your stay.
Pay in USDT, or with another method offered at checkout.
Install at home over Wi-Fi before the flight.
After landing at Incheon or Gimpo, switch on the eSIM line, enable data roaming for it and set it as your data line.

Wallet safety during KBW week

Never connect your main wallet to a QR code you scanned at a booth or side event. Use a burner wallet with a small balance for mints, POAPs and raffles.
Avoid public Wi-Fi for anything wallet-related. Venue and hotel networks are crowded and shared. Your own mobile data is the safer default.
Treat DMs after the event as phishing by default. Fake speakers, fake sponsors and fake support accounts appear every conference week.
Do not sign transactions you cannot read, especially approvals and permit signatures offered as a free claim.
Exchange booths and giveaways: read terms before you connect, and never share a seed phrase with anyone claiming to be support.

Seoul tips for KBW week

Stay near a line that reaches both the venue and the side-event districts, or budget for taxis between them.
Late September and early October is usually pleasant, with cooler evenings. A light jacket helps.
Subway runs until around midnight. Late parties mean taxis, which are affordable but hard to catch in peak nightlife areas.
Convenience stores handle T-money top-ups, snacks and chargers at any hour.
Business card culture is alive in Korean meetings. Bring a few, or have a QR contact ready.
