Under the surface

The pond runs deep

Fish it Degen! has multiple on-chain mechanics built into the contract.

01 / CAST

catch_(amount)

Mint 1-10 fish per txn. First fish per wallet is free. MINT_PRICE = 0.0001 ETH each. Rarity rolled on-chain using block.prevrandao + nonce.

02 / SPECIALS

Special traits

Poison (1%), Twin (0.5% — double mint), Ghost (1%, after 5k minted). All traits packed into one uint256 per token. Nothing off-chain.

03 / GUARANTEED

Forced legendary

Every 500 casts, _castsSinceLastLegendary resets and one fish is forced to rarity 4 (Legendary). No exceptions.

04 / MUTATION

Mutation events

Every 100 casts, a random existing fish gets the Mutated trait set on-chain permanently. The Mutated event is emitted.

05 / BOSS

Boss battles

Every 1,000 casts a boss spawns. Call contributeToBoss(tokenId) to sacrifice a fish. Once 5 contributed, call catchBoss() to claim a free Legendary.

06 / EVOLVE

evolveSet()

Burn 5 fish of same rarity via evolveSet([ids], rarity). All 5 sent to dead address. You receive 1 fresh Legendary with Mutated trait.

07 / CURSED

Cursed pond

Owner activates Cursed Pond (3 uses lifetime). When active, rarity odds fully invert — Legendary gets common odds, Common gets legendary odds.

08 / TROPHY

Trophy system

Highest-scoring fish (rarity × 1000 + species) holds the Trophy trait. Updates automatically when a higher-rarity fish is minted. One trophy at a time.

09 / HISTORY

Catch history

Last 3 wallets to hold each fish stored on-chain in catchHistory. Updates automatically on every transfer.

Questions

Common questions

Is the art really stored on Ethereum?

Yes. The pixel-art drawing engine (~33KB) is stored in two SSTORE2 blobs inside FishRenderer.sol. The tokenURI assembles a self-contained animated SVG. No IPFS, no CDN, no expiry.

How does the free first fish work?

The contract tracks each wallet with hasFreeCast. Your first catch_ call is free (minus gas). Every fish after costs 0.0001 ETH. Up to 10 per transaction.

How does the evolve mechanic work?

Call evolveSet([id1,id2,id3,id4,id5], rarity) with 5 fish of the same rarity you own. All 5 are burned to 0xdead and you receive 1 Legendary with the Mutated trait.

What is the Twin trait?

0.5% chance per mint. When rolled, the contract mints TWO identical fish instead of one — both go to your wallet at no extra cost.

How is rarity determined?

On-chain using block.prevrandao + timestamp + wallet + nonce + tokenId. Odds shift as supply decreases. One guaranteed legendary every 500 casts.
