A rewards token for verified humans on World Chain
BYT is a capped, burnable ERC-20 token deployed on World Chain, the human-first Ethereum Layer 2 built by the Worldcoin ecosystem. BYT powers BYT Rewards, a mini app that runs inside World App, where every user is a unique human verified by World ID.
The premise is simple: token rewards are only meaningful if they reach real people. By living inside World App and gating its core bonus behind World ID, BYT distributes value to verified humans instead of bots and sybil farms. Holders can earn BYT through participation, trade it against WLD on Uniswap, and send it to other humans, all gas-free, because World Chain sponsors transaction fees for verified users.
On-chain reward programs and airdrops share a structural flaw: an address is not a person. A single actor can spin up thousands of wallets and scripts to capture rewards meant for a community. The result is familiar: emissions are drained by farmers, genuine users receive a fraction of what was intended, and the token's distribution is concentrated from day one.
Traditional defenses (KYC, captchas, social graphs) are either privacy-invasive, easily defeated, or both. What reward systems actually need is proof of unique personhood that preserves privacy.
BYT is built natively inside World App and uses World ID for proof of personhood. World ID lets a user prove they are a unique human (and, with Orb verification, that they are verified to the highest level) without revealing their identity. This single design choice changes the economics of rewards:
BYT is a standard, audited-pattern ERC-20 built on OpenZeppelin contracts (ERC20Capped, ERC20Burnable, Ownable), compiled with Solidity 0.8.28.
| Parameter | Value |
|---|---|
| Name / Symbol | BYT Token / BYT |
| Standard | ERC-20 (capped, burnable) |
| Network | World Chain (chain ID 480) |
| Decimals | 18 |
| Hard cap | 21,000,000 BYT (immutable) |
| Supply minted to date | 5,000,000 BYT |
| Minting | By owner only, never above the cap |
| Burning | Any holder may burn their own BYT |
The 21,000,000 hard cap is enforced in the contract itself: any mint that would exceed it reverts. The cap can never be raised. Burning is supported, which can only ever reduce supply.
BYT follows a mint-as-needed, hard-capped model rather than a single fixed supply. Of the 21,000,000 maximum, 5,000,000 BYT exist today. The remaining 16,000,000 are unminted and will only be created, up to the cap, to fund rewards, liquidity and ecosystem growth. Because minting is an owner action recorded on-chain, anyone can audit total supply at any time.
The 5,000,000 BYT minted to date are allocated as follows, read live and verifiable on-chain:
| Allocation | Amount (BYT) | Share | Notes |
|---|---|---|---|
| Treasury & ecosystem reserve | 3,726,317 | 74.5% | Held by the owner/treasury for rewards, liquidity & growth |
| Locked reserve | 1,000,000 | 20.0% | Held on-chain, not in circulation |
| Community | 251,780 | 5.0% | Held in user wallets |
| Reward campaigns | 21,935 | 0.4% | Distributor pool for signed reward claims |
BYT is a utility and rewards token. Its roles are: (a) the reward unit paid for participation; (b) a medium of peer-to-peer transfer between verified humans; and (c) a tradable asset paired with WLD on Uniswap v4. BYT does not represent equity, debt, profit-sharing or any claim against a legal entity.
Participation rewards (daily claims, referrals, the World ID bonus) are delivered through the Rewards Distributor (RewardsDistributor), which pays out using off-chain signed approvals:
Security properties: each nonce is single-use (replay-protected), and the signature is bound to msg.sender, so a stolen signature is useless to anyone else. The signer key can be rotated by the owner.
The one-time World ID Bonus is gated by World ID using IDKit (v4) with Orb-level verification. Each successful verification yields a nullifier hash that the backend stores; the same human can never claim the bonus twice, and unverified actors cannot claim it at all. World ID proves uniqueness and humanity without revealing the user's identity.
In the interest of full transparency, BYT is currently operator-controlled, not yet decentralized. A single owner/treasury account holds the following powers:
This concentration is a deliberate launch-stage tradeoff for speed and flexibility, and it is disclosed openly. The intent (Phase 4) is to place these powers behind a multisig and/or timelock and to give the community input over emissions and treasury. Until then, users should understand that they are trusting the owner with the powers listed above.
Completed items are live on-chain today. Later phases are intentions, not commitments, and may change.
| Phase | Status | Highlights |
|---|---|---|
| 1. Launch | Done | Token, mini app, World ID bonus & signed rewards live on mainnet |
| 2. Growth | In progress | World App store listing, deeper Uniswap liquidity, expanded earn mechanics, and pursuing an independent audit |
| 3. Utility | Planned | More ways to spend BYT, partner campaigns, public transparency dashboard |
| 4. Decentralization | Exploring | Owner powers behind multisig/timelock, community input on emissions & treasury |
All contracts are deployed and verified on World Chain mainnet (chain ID 480).
