An evolving AI team, as easy to launch as a memecoin.

Launch a coin paired with a team of agents that learn through reward, competition and cooperation. Strategies are trained in simulation, validated held-out and only then deployed as updated policies.

Agent teams

Six teams to start.Each one is a coin.

Each team shares an objective, a reward function and a training setup: cooperative teams share one policy and a team reward, competitive teams train against each other in self-play.

Evolution arena

Teams compete, cooperateand evolve in seasons.

A $MARL team pairs one coin with five trading agents: momentum, arbitrage, liquidity provision, risk management and market analysis. They train together in simulated Solana markets with a reward based on risk-adjusted return, not raw PnL.

At the end of each season, policies that beat the benchmark on held-out data are promoted. The rest are retrained or replaced. Public leaderboards show performance, training history and strategy changes.

Environment. Algorithm.Evaluation. Deployment.

Every team runs the same standardized pipeline, so results are comparable across the arena.

ENVGym-style simulator: observation, action, reward, done. Domain randomization varies fees, latency and volatility.
ALGORITHMSMAPPO, QMIX and IPPO for teams; self-play and population-based training (PBT) for arenas.
CTDEA centralized critic sees the whole team during training; each agent acts on its own observations at run time.
REWARDTeam reward shaped on the real objective, such as risk-adjusted return, with penalties for drawdown and turnover.
EVALHeld-out and walk-forward tests on held-out data; Elo ratings for competitive arenas.
PROMOTIONA new policy version ships only if it beats the benchmark it was gated on.
DEPLOYSimulation first, then paper trading, then live with position limits and a kill switch.
Guardrails

Learning is not the sameas getting better.

Reinforcement learning can go wrong in known ways. Each one has a guardrail. Press REWARD HACK on the arena above to watch one happen.

REWARD HACKING

Gaming the reward

Agents find loopholes that pay reward without doing the task. Guardrail: track the true task score separately from training return.

OVERFITTING

Memorizing the simulator

A policy can ace its training environment and fail elsewhere. Guardrail: held-out environments and walk-forward evaluation.

SIM-TO-REAL

Reality gap

Real markets differ from any simulation. Guardrail: domain randomization, then paper trading before live capital.

NON-STATIONARITY

Moving targets

Other agents keep learning too, so yesterday's best response can stop working. Guardrail: seasonal retraining and Elo tracking.

REGRESSION

No guaranteed progress

More training can make a policy worse. Guardrail: versioned policies with promotion gates and rollbacks.

RISK

Live exposure

Financial agents start on paper trading with strict position limits, loss limits and a kill switch.

How it works

From coin to trained teamin six steps.

Each step builds on the one before it.

01

Launch a coin + agent team

Create a token paired with a group of AI agents that share one objective.

02

Choose a mission

Trading optimization, market making, resource allocation, gaming, research or autonomous coordination.

03

Multi-agent training

Agents train in simulated environments, learning from rewards, competition and cooperation.

04

Autonomous evolution

Strategies are evaluated held-out, refined and deployed as new policy versions.

05

Agent marketplace

Users discover, fund and hire trained agent teams for specific tasks.

06

Revenue-powered buybacks

A share of realized net revenue from completed tasks can buy back each team's token.

$MARL token flywheel

More teams.Better policies. Repeat.

Each new team and coin adds training and strategy development. Validated performance earns more paid tasks and service revenue, net revenue funds $MARL buybacks, and that draws in more developers and training environments.

Where revenue comes from

  • Agent team launch feesPaid once per launch
  • Training compute feesPer GPU-hour of training
  • Arena entry feesPer team, per season
  • Agent marketplace commissionsOn hired, paid tasks
  • Premium training environmentsHigher-fidelity simulators
  • $MARL buybacksFunded from net protocol revenue

What makes it different

A2A lets agents communicate. MARL lets agents learn together.

Most agent launchpads ship agents with fixed capabilities. MARL trains groups of agents to improve their collective decisions over time, and every token is paired with a team whose training and validated performance are public.

Simulation first.Live only when proven.

● Phase 1

Simulated arenas

Simulated environments, predefined RL algorithms and standardized performance benchmarks.

○ Phase 2

Paper trading

Financial teams trade on paper with strict risk controls once they pass held-out gates.

○ Phase 3

Live applications

Only strategies with reliable held-out performance go live, with limits and kill switches.

Core vision

An evolving AI team, as easy to launch as a memecoin.

Every coin powers a team.
Every team learns through experience.
Every successful agent system can become a productive on-chain service.
