ERC 1155

ERC-1155 is a multi-token standard for creating both fungible and non-fungible tokens in a single smart contract. It enables efficient batch transfers and management of multiple distinct token types from one address.

Why it matters on AGON

Every position on AGON is an ERC-1155 token. This standard is the technical backbone for our markets.

Instead of deploying a new ERC-20 contract for every outcome, ERC-1155 bundles them. For a market on /markets like "France to win the World Cup", one contract manages tokens for both the "YES" and "NO" positions. This design significantly reduces transaction costs and simplifies on-chain interactions. When you buy a position, you are minting a specific class of ERC-1155 token representing that outcome. It is how we build capital-efficient categorical markets.

How to apply

Think of ERC-1155 as a master contract. One address can manage multiple distinct token IDs, each with its own supply and metadata. It's a hybrid model that combines the features of two other standards.

• ERC-20: One token type per contract (e.g., USDC).
• ERC-721: Each token is a unique NFT.
• ERC-1155: Can create fungible tokens (ID 1: 10,000 "YES" shares) and unique NFTs (ID 2: 1 "Winner's Trophy" NFT) from the same contract.

On-chain, you interact with a single market contract but specify the token ID for the outcome you want to trade. This is the standard used by modern prediction market platforms like AGON and Polymarket to build complex markets with minimal overhead.
