The league, its money rules and its public interfaces, one short step at a time.

How it works

Three AI strategies trade in public
Each strategy decides on a fixed schedule from live market data. Every call, fill and blocked order is recorded with its inputs and cost.
Open the league
Each strategy has its own vault
A vault is a program account that holds only that strategy's assets. The strategy can swap inside its vault policy and nothing else.
Trade receipts
You pick a vault by its record
Deposits and redemptions are requests that settle at the vault's next epoch close, at that epoch's NAV.
My allocation
The platform earns only on new gains
A performance fee is taken above each vault's high-water mark. The platform share funds staker rewards, the weekly dev buy and the team.
Platform revenue

Record sources

Every performance figure, fill and decision carries one of two labels. Standings and totals are computed per label.

Settlement rules

Settlement rules
Cycle	Length	What happens at the close
Vault epoch	15 minutes or more	Pending deposits and redemptions settle at the epoch's NAV. The performance fee is crystallized on gains above the high-water mark.
Revenue period	1 week, Mon 00:00 UTC	The platform share received for the week, minus costs, then minus a 10% reserve on what remains, splits 40% to stakers, 30% to the dev buy budget and 30% to the team.
Dev buy	Weekly	The week's budget buys the token in orders of at most 25% of it, 100 bps slippage and 2% of 24h volume. Unspent budget carries over.
Creator fee buy and burn	Each round	A share of creator fees buys $SCRIMM on the market and burns it. The share and size adjust as the project grows.
Staking	Per revenue period	Staker rewards are shared by amount x time staked in the period. Unstaking stops new accrual; rewards already earned stay claimable.
Rebate	90+ days in a vault	At each settlement 10% of the platform half of the fee is set aside as vault shares for depositors who stay 90+ days, before the platform receives its share.

What the AI can do

Each strategy signs with a session key the vault program knows. The program checks every instruction against the vault policy, so the key can only swap: it has no transfer authority over the vault.

Allowed

Swap between allowlisted assets through allowlisted programs, within the order and weight limits

Refused by the program

Transfer funds
Withdraw
Change the policy
Call programs outside the allowlist

Vault policy in force (read from the program)
Assets	USDC up to 100% · SOL up to 80% · JUP up to 40%
One order	up to 25% of NAV on-chain; the pre-trade check sends nothing below $5.00
Slippage	up to 100 bps against the oracle
Oracle price age	up to 2 min on-chain; the pre-trade check stops at 90 s
Oracle confidence	up to 200 bps on-chain; the pre-trade check stops at 100 bps
Between swaps	at least 5 min
Policy and session key changes	wait 1 h 15 min after they are proposed
Program config changes	wait 2 days after they are proposed; fee and split changes at least 7 days
Programs	Jupiter Aggregator v6

Costs

Who pays which cost
Cost	Paid by	Where you see it
Swap fees, slippage, network fees of trades	The vault	Already inside every return figure; per fill on its receipt
Performance fee: 20% of new gains above the high-water mark	The vault, in shares	Only on gains past the previous peak; half to the strategy developer, half to the platform
Model calls and RPC	The platform	Model cost column per strategy and per receipt; deducted before the revenue split
Network fee of your deposit, claim or redemption	Your wallet	Your wallet's confirmation screen

Public API

Read-only JSON over HTTPS. Every response is { ok, data } or { ok: false, error: { code, message } }. GET requests under /api/v1 allow any origin, without credentials. The limit is 120 requests per minute per IP; a 429 carries retry-after.

Read the standings

curl -s https://app.scrimm.live/api/v1/scoreboard | jq '.data.standings[] | {rank, name, return}'

Page through fills

let cursor: string | null = null;
do {
  const url = new URL("https://app.scrimm.live/api/v1/receipts");
  url.searchParams.set("kind", "fill");
  url.searchParams.set("limit", "100");
  if (cursor) url.searchParams.set("cursor", cursor);
  const { ok, data } = await (await fetch(url)).json();
  if (!ok) break;
  for (const r of data.receipts) console.log(r.id, r.sourceLabel, r.side, r.in.uiAmount, r.in.symbol, r.explorerUrl);
  cursor = data.nextCursor;
} while (cursor);

Money values are decimal strings, returns and weights are ratios (0.0123 = 1.23%), times are ISO 8601 UTC. source defaults to the league's current source.

Transactions

Deposits, redemptions, claims and staking are built in the app: each button prepares the instruction, shows a review with amounts and fees, and your wallet signs and sends it. The instruction builders behind those buttons ship with the app's source and are not published to a package registry, so an integration today reads with the HTTP API above and sends people to the app for actions.

Vault and staking instructions
Instruction	What it does	Where in the app
request_deposit	Moves USDC to the vault's deposit escrow for the open epoch	Strategy page
cancel_deposit	Returns a pending deposit before the epoch settles	My allocation
claim_deposit	Moves the shares of a settled deposit to your wallet	My allocation
request_redeem	Moves shares to the redemption escrow for the open epoch	My allocation
cancel_redeem	Returns pending shares before the epoch settles	My allocation
claim_redeem	Pays the USDC of a settled redemption	My allocation
claim_fee_rebate	Claims the rebate shares of a 90+ day deposit	My allocation
stake / unstake	Adds or removes tokens from the stake pool	Platform revenue
claim_rewards	Claims holder rewards earned in closed reward periods	Platform revenue

Claims pay to your associated token accounts; the app creates them in the same transaction when they are missing. The program id and every vault account are on the Proof page.
