The Artist’s Journey
In the early months of 2019, the blockchain gaming and digital collectibles space was searching for its next evolutionary leap. CryptoKitties had proven the concept of non-fungible tokens back in late 2017, clogging the Ethereum network and demonstrating that digital ownership could capture mainstream imagination. But the ERC-721 standard that powered those collectible cats carried significant limitations — each token required its own smart contract interaction, gas costs were prohibitively high for game developers, and batch operations were virtually impossible without complex workarounds.
Enter Witek Radomski, the co-founder and chief technical officer of Enjin Coin. Radomski had been working on a better way to represent digital assets on the blockchain since 2017, when he created the first implementation code for ERC-1155. By June 2019, his creation was officially adopted as an Ethereum token standard — a milestone that would fundamentally reshape how digital collectibles and in-game assets are created, traded, and managed on the blockchain.
Collection Mechanics
The ERC-1155 multi-token standard introduced a paradigm shift in how blockchain assets are structured. Unlike its predecessor ERC-721, which required a separate smart contract for each unique token, ERC-1155 allows a single contract to manage both fungible and non-fungible tokens simultaneously. This means a game developer can issue gold coins (fungible), legendary swords (non-fungible), and health potions (semi-fungible) all through one unified smart contract.
The efficiency gains are substantial. Batch transfers allow hundreds of different token types to be sent in a single transaction, reducing gas costs by up to 90% compared to ERC-721. For the digital collectibles market, this meant creators could mint entire collections, distribute them to users, and facilitate trades without the overhead that had made blockchain gaming economically challenging.
Enjin’s ecosystem in mid-2019 was already demonstrating the standard’s potential. The Enjin Platform provided tools for game developers to integrate blockchain assets without deep smart contract expertise, while the Enjin Wallet offered a mobile hub for managing gaming collectibles and crypto assets alike. With Ethereum trading at $270 and the broader crypto market in bull mode — Bitcoin had surged past $8,700 — the timing for a more efficient NFT standard could not have been better.
Utility and Perks
What set ERC-1155 apart from earlier token standards was its approach to utility. Each token could carry metadata defining its properties, rarity, and use cases across multiple games and applications. A sword earned in one game could retain its attributes when transferred to another — a concept Enjin called the multiverse, where digital items carry real value across interconnected gaming worlds.
The standard also introduced the concept of semi-fungible tokens, a category that did not fit neatly into either the ERC-20 (fungible) or ERC-721 (non-fungible) frameworks. A concert ticket, for example, is fungible within its tier — any seat in the same row is interchangeable — but becomes non-fungible once assigned to a specific event date and seat number. ERC-1155 handles these edge cases natively, opening doors for digital collectibles that blur the line between currencies and unique items.
For collectors, the benefits extend beyond gaming. Digital art, virtual real estate, event tickets, and loyalty rewards can all be represented as ERC-1155 tokens, with the same contract managing diverse asset types. This universality reduces fragmentation in the NFT ecosystem, where different standards and platforms had previously created isolated islands of digital ownership.
Secondary Market Action
The adoption of ERC-1155 as an official Ethereum standard in June 2019 sent ripples through the nascent NFT marketplace. While platforms like OpenSea were still in their early stages — total NFT trading volume for all of 2019 would barely reach $5 million — the new standard lowered barriers to entry for creators and developers who had been deterred by high gas costs and technical complexity.
Animoca Brands, a gaming company that would later become one of the most prominent investors in the NFT and metaverse space, was already experimenting with blockchain-based collectibles around this time. The company announced F1 Delta Time, a blockchain racing game featuring officially licensed Formula 1 NFT collectible cars, with auctions beginning in June 2019. The game represented one of the earliest examples of a major entertainment brand embracing digital collectibles on the blockchain.
The secondary market implications of ERC-1155 extend beyond simple trading efficiency. Because a single contract can manage an entire collection, marketplace operators can build more sophisticated trading interfaces, bundle multiple items in single transactions, and implement royalty structures that automatically compensate creators on every resale — features that would become standard in the NFT boom of 2021.
Final Verdict
The official adoption of ERC-1155 in June 2019 was a watershed moment for digital collectibles that, at the time, went largely unnoticed by the broader crypto community focused on Bitcoin’s surging price and the looming DeFi summer. Yet the standard’s impact would prove far-reaching: today, ERC-1155 underpins billions of dollars in NFT trading volume and serves as the backbone for major gaming and collectibles platforms worldwide.
Enjin’s journey from a gaming community platform to a foundational infrastructure provider illustrates how the most transformative innovations in crypto often emerge not from headline-grabbing price movements, but from the quiet, technical work of developers solving real problems. As the NFT market continues to evolve, the principles embedded in ERC-1155 — efficiency, flexibility, and cross-platform composability — remain the gold standard for digital asset design.

Radomski shipped working implementation code two years before ERC-1155 was official. EIP governance is where good ideas go to age
batch transfers in a single tx is huge for gaming. gas savings alone make this worth it over 721
gas savings were real but the gaming adoption never materialized at scale. most game devs went with centralized backends and just used nfts for marketing
nft_graveyard batch transfers saved like 90% on gas for game items but devs still picked centralized backends. the standard won the technical battle and lost the war
batch transfers saving gas is nice but gaming went centralized anyway. the standard won technically, lost in adoption
Iris T. the standard won technically and lost in adoption because game studios dont want players actually owning items. kills the recurrent revenue model
Mehmet A. game studios dont want players owning items because it kills their recurrent revenue. ERC-1155 was technically perfect and commercially irrelevant
game_dev_skep_ blaming business model is a cop out. Gods Unchained proved you can run a real game on ERC-1155. the problem is most studios raised on “play to earn” tokens not on actual gameplay loops
game_dev_skep_ game studios killed item ownership because secondary markets eat their DLC revenue. ERC-1155 was never the problem, the business model was
nft_graveyard devs picking centralized backends over a working standard tells you everything. web3 gaming was never about ownership it was about fundraising
witek radomski basically solved the nft scaling problem before anyone knew it was a problem
cryptoKitties clogging ethereum in 2017 was the wake up call. took almost 2 years to get a proper fix
ERC-1155 was technically perfect and commercially dead because no game studio wants players trading items on a secondary market. the standard solved the wrong problem
radomski wrote the ERC-1155 implementation code in 2017 and it took until june 2019 to become an official standard. EIP process is painfully slow
radomski shipping the implementation two years before the standard was official tells you everything about how slow EIP governance moves
game_stack two years from impl to official standard. EIP governance moves at glacial speed
batch_tx two years from implementation to official standard. EIP governance is where good ideas go to wait
Raluca M. two years from implementation to official standard is actually fast for EIP governance. ERC-4337 took longer and had less pushback
gas_batch_ 90% gas reduction was massive technically. but game studios went centralized anyway because owning the backend is worth more than saving gas fees
batching 100 token transfers in one tx instead of 100 separate ones cut gas by like 90% for game devs. the standard was technically brilliant
gas_batch_ the 90% gas savings from batching was technically elegant but Gods Unchained is the only game that proved it works at scale. everyone else raised on P2E tokens and died
gas_batch_ spot on about the 90% gas savings. we shipped an ERC-1155 inventory system for a game client in 2020 and batch transfers were night and day vs ERC-721. the problem was never technical
Radomski wrote the ERC-1155 implementation in 2017 and it took 2 years to become official. EIP governance is where good ideas go to age. Gods Unchained proved it works though
batch transfers cutting gas by 90 percent was technically brilliant. shame most game studios just used centralized backends and NFTs for marketing
Sang-woo L. 90% gas reduction and studios still went centralized. tells you the technical advantage was never the bottleneck. web3 gaming was a fundraising narrative not a product strategy
