Call it.Back it.Prove it.
Post a perps trade call as a card that can never be edited, with a USDso bond behind it. Followers take it with the stop and target already set. The market price settles it.
Somnia Tokyo testnet. Paper USDso.
Reading the latest calls from the chain...
The problem
Anyone can post a trade call. Nobody pays for being wrong.
- A post can be edited, deleted or forgotten once the move has happened.
- Followers copy late, by hand, and often without a stop.
- A caller with a bad record can start over with a new account.
Callout writes the call on chain and puts money behind it. The price decides who was right.
How it works
Four steps, all on chain.
1
Post
Write the market, direction, entry, stop, target and expiry. The card goes on chain and can never be edited.
2
Bond
Say how much follower size you cover, then back it with a USDso bond of at least 2% of that.
3
Take
Followers take it on dreamDEX perps with the stop and target already armed. You earn a 10 bps builder fee on every follower fill.
4
Settle
The market's on-chain mark price settles it. A hit returns your bond. A stop pays it to the people who took the call.
Who gets the bond
Be right and it comes back. Be wrong and followers are paid.
Caller TakersThe last bar is an example. The real split follows the price at expiry.
If nobody took the call, the bond always comes back to the caller.
Live proof
Every outcome is a public on-chain transaction.

Built on
dreamDEX perps and Somnia Reactivity.
dreamDEX perps
Followers trade on dreamDEX with the call's stop and target armed. Each fill carries the card's tag, so the caller earns the 10 bps builder fee.
Somnia Reactivity
The chain counts each take in the same block as the fill, and settles every call at its own expiry. No server, no database, no indexer.
