What 300FIT does

300FIT, founded in 2018 and headquartered in Seoul, operates as TDMETA since its November 2024 rebrand, running a Web3 sports ecosystem on Kaia Chain (the integrated L1 blockchain combining Klaytn and Finschia developed by Kakao and LINE). The company's core product, TDT Championship, is a sports league platform where users own Sports NFTs representing dramatic game moments from partnered athletes and federations, build fantasy teams, compete in real-world leagues, and earn rewards tied to athlete performance. Supporting products include walk-and-earn NFT gamification (covering Olympic stars, UFC champions, and world swimming record holders), the Endorfer DAO NFT membership (10,000 units with voting rights and priority purchase rights), the ESGG environmental initiative (gamifying CO2 reduction through 10,000 steps in 30 days), the $TDT utility token with a deflationary burn mechanism, and the NFTmall marketplace at sportsnft.co.kr. Distribution runs through self-serve channels — the TDT Championship platform, sportsnft.co.kr, the @300fit_official / @TDMETA_Official social accounts, Discord, KakaoTalk, and a planned Q1 2025 LINE Messenger Mini-Dapp targeting 196 million users. Revenue is generated via NFT sales and trading transaction fees, token ecosystem activity, and sports IP licensing royalties, though no revenue figures are publicly disclosed and the company remains unfunded with a sub-10-person team. Strategic IP rights with World Aquatics (1B+ event viewers), Asian Badminton Federation (Japan/Indonesia/Malaysia access), and 70+ athletes form the primary competitive moat, partially offset by the loss of Bithumb exchange trading support in late 2024 and a failed legal challenge to reverse that delisting.

2. $TDT Token Ecosystem: Revenue generated from token circulation including league participation fees, NFT upgrades, and game item purchases. A portion of $TDT tokens used in ecosystem services is burned, creating deflationary token economics.

Core offering

300FIT (now TDMETA) operates a Web3 sports league platform called TDT Championship, built on Kaia Chain, where users can own sports-themed NFTs minted from athlete game videos, records, and stories. Users create fantasy sports teams, participate in real-world leagues, earn rewards through walk-to-earn gamification, and use the $TDT utility token (with a deflationary burn mechanism) for NFT purchases, league entry, player cheering, and governance voting.

Product overview

300FIT rebranded to TDMETA (Season 2), operating a platform-plus-ecosystem model. The central product is the TDT Championship web3 sports league on Kaia Chain, where users own Sports NFTs of dramatic game moments, create teams, compete in real-world leagues, and earn rewards tied to athlete performance. The Gamification layer enables walk-and-earn NFT collection; the Endorfer NFT membership provides enhanced rewards, free NFTs, and governance rights; and ESGG adds an environmental mission layer. The $TDT token serves as the unified utility token across all services (NFT purchases, league entry, voting, player cheering), with tokens burned upon usage to create a deflationary economy. A LINE Messenger mini-dapp targets 196M LINE users for ecosystem expansion.

Emerging players

• STEPN: Move-to-earn Web3 fitness app where walking/running earns tokens and NFTs. Closest functional analog to TDMETA's walk-to-earn Sports NFT gamification layer.
• Rally: Creator token economy platform enabling independent communities to issue social tokens with built-in commerce. Comparable to TDMETA's $TDT token + DAO governance + fan monetization stack.
• ZTX (ZepetoX): Web3 metaverse platform with virtual fashion and creator economy tied to social gaming. Comparable as a Kakao/Korean-affiliated Web3 consumer platform pursuing adjacent gamified engagement.

Direct peers

• SportsIcon: Sports NFT marketplace offering officially licensed athlete collectibles and digital memorabilia. Direct competitor in the sports NFT collectibles vertical with similar IP rights strategy.
• Sorare: Operates a fantasy sports + sports NFT platform where users buy, trade, and compete with officially licensed digital player cards. Most direct global competitor to TDMETA's TDT Championship model across multiple sports.
• Dapper Labs (NBA Top Shot): Pioneer in licensed sports NFT collectibles (NBA Top Shot) with league IP partnerships and a tokenized ecosystem. Direct analog for TDMETA's World Aquatics and federation NFT rights model.
• Socios.com (Chiliz): Sports fan token platform partnering with FC Barcelona, PSG, and others to issue club-specific tokens for fan engagement and governance. Comparable to TDMETA's $TDT utility token + DAO voting mechanics for sports IP.
• NFTStars: Sports NFT platform focused on athlete collectibles and gamified fan engagement with token rewards. Closely comparable in scope of sports-IP-to-NFT conversion.

Others

• Klaytn (Ground X): Underlying L1 blockchain (now part of Kaia) developed by Kakao. Infrastructure-level enabler and ecosystem peer rather than direct competitor; relevant given TDMETA's Kaia Chain commitment.

Regional players

• Fantium: Fan engagement and athlete monetization platform enabling fans to invest in athlete earnings via tokenized contracts. Comparable athlete-monetization angle with a different (investment-focused) mechanism.
