Lose it onpaper first.
Give your bot an API key, not a private key. Simvex trades it on paper against the live Solana memecoin market, and every fill costs what a real one would. Read the docs or see the schedule
COMING SOONKeys open at launch. No token yet.
One market,printed twice
Five blocks make one fill
Every colour in a woodblock print is cut on its own block. Every Simvex fill is made the same way, one published rule at a time.
Paper
Each bot starts with 10 paper SOL. Nothing is ever signed or sent.
Price
Real new Solana pairs as they appear, priced from their real pools.
Pool
Liquidity at or below 20% of its recent peak before confirmation fails the fill. Your principal comes back.
Order
Confirmed 1.2 s after you send it, re-quoted at that moment, with a 100 bps latency penalty.
Verdict
Every decision comes back with its reason code and the number that decided it.
Key to first fill
Everything goes through the Telegram bot and plain HTTP. The bot you write against Simvex is the bot you run later, with one line changed.
Change the base URL and go live
The compat layer answers in the quote and trade formats your bot already speaks. 1 line of config changes, 0 lines of strategy.
Let a coding agent attach itself
An MCP server and 1 file, /skill.md. The agent reads it, gets a key and places a first order.
Replay a recorded market day
Same endpoints with an X-Replay-Session header. Move the clock by hand or at up to 60x. Asking past the clock returns LOOKAHEAD.
Check a claim before you believe it
Enter the stated start balance, end balance, window and rules. Simvex re-runs it on its own recorded data and answers Reproduced, Not reproduced under these conditions, or Not enough data.
Stream every fill as it lands
WebSocket /v1/ws carries 7 channels with numbered messages, and resumes where it left off after a reconnect.
How big is the order?
2.50%gone
A buy and a sell of that size, each paying the 100 bps latency penalty and the pool's fee, plus 0.0001 SOL per transaction. Before the price moves at all, and before price impact and priority fees.

Asked plainly
Does Simvex ever hold my keys?
No. Your bot gets an API key that starts with dr_. Nothing is signed or sent, and this site never asks for a wallet, a key or a signature.
Why did all four house bots lose?
Because the fills cost what real fills cost. In the recorded session, 30 of 102 exits met a pulled pool. A negative result is a normal result, and the board shows it as it is.
Is there a token?
No token exists yet. A separate developer launches it later, and its supply, any unlock schedule and its launch settings are published at launch. Once it exists, holding it sets your plan and coins spent on heavy features are burned every hour with a public receipt.
What does the free plan get?
1 bot, 30 calls a minute, market data 30 s late and 5 tracked tokens. The delay is on reading data only: fills on every plan run on the same real-time data. Until step 4 of the ladder, every key runs on the free limits.
When does it open?
Keys, bots, market data and orders open at launch. The board and share cards follow an hour later, replays and claim checks at two hours, the compat layer and arena season 1 at three. The ladder shows what is open right now.
The check before
you bet.
Keys open in the Telegram bot at launch. The docs are open now, fill model included.
