ERC-EVOLVE is a new token standard built on Uniswap v4. Holding earns experience. Long-term holders trade cheaper than short-term flippers — and earn a continuous slice of every swap fee. Loyalty becomes a measurable, on-chain property of the protocol.
Every holder looks identical to the protocol. Conviction has no weight. Time held has no value. On-chain identity ends at the address itself.
A bot that bought in block zero and a believer who has held since the seed round pay the same fee, receive the same units, and accumulate the same on-chain reputation: none. Loyalty programs have been bolted on — wrapped tokens, off-chain points, reflection mechanics — but none of them live where the trading happens.
Uniswap v4 hooks change what's possible at the AMM layer. ERC-EVOLVE uses them to make every wallet's history part of its trading economics.
A token, a v4 hook, and time. No oracles. No off-chain dependencies.
Every wallet's experience grows as the integral of its balance over time: ΔXP = balance × Δt × baseRate. The contract settles XP lazily on every transfer; no staking, no opt-in. The longer and larger you hold, the more you earn.
Uniswap v4's beforeSwap hook checks the trader's XP, derives a level, and overrides the pool fee with that wallet's personal fee tier — from 1.00% at Lv 0 down to 0.05% at Lv 50. Long-term holders trade for a fraction of what new wallets pay.
The hook routes 30 bps of each swap into a Loyalty Treasury that continuously pays out to wallets at Hatchling (Lv 5) or higher, weighted by balance × tier_multiplier. Paperhand traders are, in effect, paying yield to diamond hands.
Each tier unlocks a lower personal fee, a bigger yield share, and discrete utility. Mythic isn't a badge — it's a meaningfully different economic position.
| Tier | Fee | Yield | Perks |
|---|---|---|---|
| EggLv 0 – 4 | 1.00% | 0× | Default rate. XP accruing. |
| HatchlingLv 5 – 9 | 0.90% | 1× | Baseline yield unlocks. Soulbound badge. |
| AdolescentLv 10 – 19 | 0.75% | 2.5× | Launchpad whitelist for partner allocations. |
| AdultLv 20 – 49 | 0.50% | 5× | 2× governance voting weight. NFT badge mint. |
| MythicLv 50 | 0.05% | 10× | Treasury proposal rights. Exclusive pool access. |
A cheaper fee tier reduces your cost. Loyalty Yield generates positive return. The protocol pays you to hold — funded by the people who don't.
A fixed 1B supply, minted in full at deployment, paired with ETH and seeded into the canonical v4 pool. Zero insider allocation.
Every EVO in circulation came from a swap. There are no insiders to dump, no vesting cliffs, no team allocation. The team participates the same way every other holder does — by buying from the pool. The protocol's operating model is funded by the Loyalty Treasury's fee revenue, which accrues in WETH from real trading activity, never in EVO itself.
Backwards compatible. Wallets and exchanges see a normal token. The leveling lives in extra view functions plus the canonical v4 hook.
The token contract adds soulbound per-wallet state — xp, level, lastTouch, peakBag — and exposes view functions for reading XP, level, and the wallet's effective fee. The Uniswap v4 hook implements beforeSwap, afterSwap, and beforeAddLiquidity, enforcing the dynamic fee and routing the loyalty take.
XP is non-transferable. Sending tokens to a fresh wallet does not move XP — the receiving wallet earns from there. This prevents level laundering and keeps reputation tied to time held by a single address.

ERC-EVOLVE makes conviction measurable, priceable, and rewarding — at the AMM layer, on every swap, with no third party.
