Non-custodial copy trading · built on Definitive Flash

Copy the plan.
Keep the control.

PACT is non-custodial copy trading. Leaders publish structured trade plans; your own mandate decides what to copy, how much, and how you exit. You sign every order in your wallet, and Flash executes it.

  • ✓ No custody, no private keys
  • ✓ You sign every order
  • ✓ Every decision on the record

The problem

Copy trading works for leaders. Followers pay for it.

A publisher-reported study of 100,236 copier outcomes on Binance, Bybit and MEXC found 97% of leaders green on their own PnL, but only 44% of them made money for the people copying them. The idea can be right and the copy still loses.

A different trade

Followers get a worse entry, a size that does not fit their capital, costs that erase the edge, and an exit they do not control.

Exit liquidity

A leader can buy early, publish, and sell into the buying their own followers create. Most platforms cannot see it, or do not show it.

Blind automation

Copy bots hold keys or mirror every move. Followers rarely see what they are signing, or why a trade was taken.

How it works

A leader proposes. Your mandate decides. You sign.

PACT sits between a leader's plan and your wallet. It never holds either.

  1. 01

    A leader publishes a plan

    Pair, side, Flash order type, entry, stop, target, invalidation and how many followers it can take. The leader can attach their own Flash order and Base trades as evidence.

  2. 02

    Your mandate decides

    Your own rules for that leader size the copy and return COPY, SCALE, WAIT, REVIEW or DECLINE, with the reason. A blocked plan never reaches Flash.

  3. 03

    You sign; Flash executes

    PACT gets a Flash quote, your browser re-checks the exact payload, and you sign in your wallet. Your stop and target go on as a Flash TP/SL pair on your position.

  4. 04

    Every step is on the record

    Fills, drift against the leader's entry, fees and protection are read back from Flash. Each decision joins a hash-chained evidence log your browser can verify.

What makes it different

Familiar trading. Follower-owned rules.

The shell looks like the terminals you know. What is new is who is in charge of the copy.

Mandate

One mandate per leader

Follow up to ten leaders. Each gets its own sizing (proportional, fixed or stop-risk), daily sleeve, order types and exit, inside your portfolio caps.

Policy

Policy before price

Entry drift becomes the Flash limit price; impact, cost and concentration are checked before a quote. Blocked plans are never quoted.

Wallet guard

Your browser checks what you sign

Recipient, tokens, amount, spender, fee vault and deadline are re-checked in the page. In tests it refused a quote whose amount a server had inflated 20×.

Exits

Your exit, not the leader's

PACT never mirrors a leader's exit. Your stop and target sit on Flash as a protective pair; cancelling a copy cancels both with one signature.

Evidence

Plans backed by execution

A leader's attached Flash order and Base trades are read and compared with the plan. A plan the leader's own execution contradicts is held for every follower.

Fairness

Catches leaders who dump on followers

PACT flags a leader who traded long before publishing at a better price, or whose asset left their wallet on Base while followers' copies filled. A repeat holds new copies.

World ID

Verified humans

A leader can prove one unique human is behind their wallet; one human backs one leader address. Followers can copy verified humans only, and approve Autopilot limits as a human.

Autopilot

Automation with limits on chain

An optional session key that can only sign within limits your PACT wallet enforces on chain: tokens, amounts, recipient, expiry. Revocable in one call.

Paper copies

Probation with real quotes

Every new plan is paper-copied at Flash's real all-in price, with no signature. Followers can require a leader to pass probation before copying.

Follower fairness

The first copy desk that can show a leader dumped on their followers.

Every evidence-backed plan carries the leader's own trade and its time. PACT compares it with followers' real Flash fills and with what left the leader's wallet on Base while followers were buying.

Traded well before publishing

The leader's own trade came at least 30 minutes before the plan, and followers paid at least 1% more. Trading just before publishing is normal skin in the game.

Sold into followers' buys

The plan's asset left the leader's wallet on Base while followers' copies were filling: at least a quarter of the position.

Once is a warning. Twice is a hold.

A repeat holds every follower's new copies of that leader for review, and the finding goes into the evidence log.

Honest limits

PACT reads Base. Sales on a centralized exchange, another chain or another wallet are not visible, and the page says so.

Trust

What PACT will never do

  • Hold your private key or your funds.
  • Place a trade you did not sign, or that a session key you created and limited on chain did not sign.
  • Invent PnL, win rates or leader rankings. Numbers come from Flash fills and on-chain records, or they are not shown.
  • Claim to see what it cannot: it reads Flash and Base, not centralized exchanges or other chains.
