speculative on-chain opinion markets on base

Each take is one sentence. Back it to mint conviction shares from a bonding curve. Unback to burn them. No resolution, no oracle, no investment advice. Just a curve and the math behind it.
start here
To use takes.fyi you need USDC on the Base blockchain (for backing or filing takes), plus a tiny bit of ETH on Base for gas. Other tokens and other chains are not supported. New here? See the 30-second walkthrough →

The first share is cheap. Each backing after lifts the quote a little. Each unbacking lowers it. The curve is autonomous and immutable on-chain.
How it works
01
Anyone files a take
One sentence. Costs 1 USDC. Half goes to the platform, half auto-backs the take on the creator's behalf, so every take launches with real skin in the game.
02
Backers buy conviction
Pay USDC into a constant-product bonding curve. Receive non-transferable conviction shares. Each backing pushes the per-share quote up.
03
Unbackers cash out
Burn shares back to the curve at the current quote. If others backed after you, you receive more USDC than you paid in. If they unbacked, you receive less. The math is the message.

A few honest details
- No resolution, no oracle
- No real-world outcome is being predicted. The price reflects only social conviction priced by a deterministic curve.
- Non-custodial
- USDC sits in the smart contract. There is no admin, no pause, no upgrade. Operators cannot freeze or refund anything.
- Most takes go quiet
- You can lose USDC. The downside scenario is shown next to the upside, with the same prominence, on every buy preview.
- 2% trade fee
- 1.5% to the platform, 0.5% to the take's creator. Round-tripping a position pays the fee twice, about 4% total.
